Waste Less Recycle More: How New South Wales Is Transforming the Organics Recycling Landscape

TOS37_EPA_MainImage

EPISODE SUMMARY

This week we’re in New South Wales, Australia, to learn about the Waste Less Recycle More initiative and the Organics Infrastructure Fund that will see 70 million AUD invested into organics management in the region. We speak with the Director of Waste and Resource Recovery at the NSW Environment Protection Authority (EPA), Steve Beaman, to learn more about this initiative and their plans to pull more organics out of landfills, and discuss the importance of government support and strong policy for success.

We also speak with Robert Niccol of landscape and agricultural supply company Australian Native Landscapes, to get an insight into the processor’s perspective, the challenges that the industry anticipates with this increase in supply, and to discuss further the EPA’s plans to work with industry in developing new markets with their Organics Market Development grants.

 

MADE POSSIBLE BY NSW ENVIRONMENT PROTECTION AUTHORITY (EPA)

The NSW Environment Protection Authority (EPA) is the primary environmental regulator for New South Wales. Our purpose is to improve environmental performance and waste management for NSW.

The EPA’s Waste Less, Recycle More is a five year, $465.7 million initiative that’s transforming waste management in NSW. It includes funding for organics collections, processing infrastructure and market development, business recycling, drop off centres for problem wastes and programs to tackle litter and illegal dumping.

TRANSFORMING ORGANICS RECYCLING LANDSCAPE

 

THE ORGANIC STREAM: We often talk on the organic stream about the importance of policy and government support for making a real impact with our sustainability programs, and the NSW government provides a great example of this – with a strong policy direction stemming from the objectives set out in their waste legislation, the EPA and the NSW government have initiated a host of strategies and programs to reduce waste and keep materials circulating within the economy.

In particular, a 5-year initiative that invests just over 465 million Australian dollars into increasing recycling and keeping materials out of landfill – an unprecedented amount of funding that’s pulled directly from the region’s waste levy. The Waste Less Recycle More initiative has a heavy focus on organics recycling in particular with the Organics Infrastructure Fund. To learn more about this program and the importance of a comprehensive and cohesive policy for success, we gave a call to Steve Beaman, Director of Waste and Resource Recovery at the New South Wales Environment Protection Authority (EPA).

And with a goal of diverting organics from landscape, this will of course mean an increase in organics supply at organic recycling facilities around the region. How will this impact the industry? Well after speaking with Steve we reached out to Robert Niccol of Australian Native Landscapes, or ANL, to get an insight into the processor’s perspective and discuss further the EPA’s plans to work with industry to develop new markets.

Pretty exciting episode – so let’s jump right in with Steve Beaman of the EPA…

 

INTERVIEW WITH STEVE BEAMAN (EPA)

 

TOS: So Steve, a lot is happening in New South Wales at the moment – can you fill us in?

 

STEVE BEAMAN: The New South Wales EPA and government has set ambitious waste targets, both in terms of waste avoidance and in greater recycling and recovery of material if we do generate it as waste. At the end of 2014, we just released a seven year strategy, the Waste Avoidance and Resource Recovery strategy, and that has six key focus areas. It’s about having programs in place to reduce the amount of waste being generated in the first place; it’s to increase recycling at a household, commercial and construction level; it’s about increasing the diversion of waste away from landfill; it’s about establishing community recycling centres across New South Wales to make it easy for the community to get rid of problem wastes and to do so in a safe manner; and finally it’s to reduce illegal dumping and prevent littering.

So there’s a very progressive agenda at the moment in New South Wales. And we’ve been able to have that funded from a waste levy. So, for every tonne of waste that’s disposed of in the populated areas, there’s a government levy that’s imposed on that waste disposal, and the purpose of that levy is to make recycling more cost effective against traditional landfill. And as part of that income stream, the government’s allocated over 465.7 million dollars for us to drive this change. And the change is really around three aspects, which are: greater education and community engagement, delivering new and improved infrastructure, and the last is about having a strong regulatory framework that underpins it, so there’s clarity right across the sector and the community of what the government’s expectations are around the rules about managing waste and recycled products.

 

TOS: Excellent – and there is a great emphasis on organic waste, I know – you’re directing 70 million dollars of that to an organics program.  So what is the key focus for you in terms of organics recycling at the moment?

 

SB: It’s really around those seven aspects. We’ve just run a series of grant rounds where we’ve got forty three million dollars available of that seventy million for new infrastructure. These are organic processing facilities that are typically a combination of food and garden organics processing and is usually around some form of composting technology. We didn’t have the infrastructure in place, so we’re pulling this stuff out of the bins but we needed the processing capacity to be built, and all that’s being built at the moment.

Our local authorities, our councils that provide the services to the community needed access to new and improved collection systems – and typically that has been mobile garbage bins. So, we’ve funded four hundred and forty three thousand new garbage bins and kitchen caddies, so people can sort out their waste in the kitchen and put it into the right garbage bin.

And this is an exciting one that we’ve just released, but we’ve got four million dollars around market development. And this is around the concept that now that we’ve pulled this organic material out of the system and it’s being processed in these facilities, we have to ensure that we’ve got sustainable and resilient end-markets for this material to be used. If the material gets composted it can go to urban restoration; it can got o mine-site rehabilitation; it can go back to farmland and pasture organic improvements. The thing about Australian soils is that they’re very low in organics typically, and then farming practices over the last two hundred years has depleted those organics even further.

So there’s great multiple benefits here with us taking this stuff out of landfill, processing it and putting it back on the land, improve the water-holding capacity of the land, and also improve the nutrient uptake in some of those soils that are organic poor. So we see this as a great opportunity.

We’re also, from that market development work, looking at how we can assist industry to improve the quality of the compost. Because it’s coming from the domestic waste stream, typically, it’s important to educate communities that they can’t put their used batteries into the organics bin, because it has a consequence: if that battery breaks open, you spread lead through the compost material and renders it useless for use on urban development or agricultural use.

So it’s a multi-faceted program. That’s the thing that’s really exciting about this, it’s trying to attack the issue on a couple of fronts: education and community engagement, industry development, the infrastructure component, and then having the regulations behind it that gives the community the confidence that using recycled products is the way to go.

 

TOS: Very good – and I’d like to talk about the importance of this strong policy framework that underpins everything and how that has contributed to the program’s success?

 

SB: I think the thing about Waste Less Recycle More is that success is really going to be attributable to having a really strong policy, certainty and clarity around it, and that’s why I started with the Waste Avoidance and Resource Recovery strategy. The government has set this long-term strategy, it’s adopted the targets to increase recycling, reduce illegal dumping and to prevent littering, and that really gives us the instruction that we need to go and deliver these. These are government priorities, and those priorities really stem from community expectations – the community wants to see these services being offered and want to see these improvements.

But the fact that we’ve actually been able to align a very strong policy commitment directly from government, and have that underpinned by a very strong funding program, really gives us the recipe we need to be able to deliver this program. And I think it changes the confidence in the community. They can see and engage with the EPA and government on waste and recycling now, and we’re able to provide that information out to the community – we have an excellent website called Love Food Hate Waste, which is around waste avoidance.

But this also has changed the approach by the waste sector, where it’s moving away from the traditional waste collection and waste disposal and towards trying to be a part of this new circular economy and a recycling and resource recovery agenda. So we see this as a great opportunity to change the agenda in New South Wales.

 

TOS: That’s very exciting. And let’s talk more about the market development side of things for a moment. Developing compost markets is quite a big task – can you tell me a little more about your plans here, and are you anticipating any challenges?

 

SB: with the markets for compost, I think we’re really pulling a lot of material out of the system, and we need to be careful. That’s why we’re investing in a market development program, so we get that balance right and we don’t disturb the system too much by pushing too much material through the system, thereby increasing the supply and affecting prices. So we need to think carefully and we’re working in partnership with industry around exploring how we can help industry and local government to stimulate the markets so that we’re actually resilient for the longer term, and when more material comes through we’ve actually generated the demand at the end-use level. And that the farmers and the urban restoration workers and so on are more comfortable in using the organics in their soils and agricultural systems, so we can get that market to mature as fast as we can and it then becomes a self-sustaining system.

 

TOS: It’s great that there is so much investment going into it. But moving out again – are there any pressing challenges you’re facing at the moment in terms of organics recycling – or any problem areas you’re focusing on?

 

SB: The single main challenge for us is contamination. This is around trying to educate the community and industry. And this is why it’s a very interesting program, because people have things in their household that they mightn’t know how to get rid of. Oil, paint, gas bottles, batteries, smoke detectors, light bulbs… And so if we find that they’re unsure, they’ll often inadvertently do the wrong thing and put it into the wrong bin.

And this is why part of another program of Waste Less Recycle More is the community recycling centres. So there’s another seventy million dollars to build these drop-off centres, and the aim is to have eighty-six of these centres where you can drop off all those problem items you’ve got in the household for free. So if we can make it easy for the community to easily dispose of these problem materials, and also educate them on why it’s important that they don’t drop these materials into their organics bins, then that’s going to keep improving the product quality of our organics and compost.

It’s a real issue for us, and we’re starting to do some exciting work on rolling out a state-wide education campaign to help improve the knowledge and behaviour of householders. And that’s what we’re starting to work on next.

 

TOS: And all this comes from the funding from the waste levy. Do you consider this waste levy to be the most important, or crucial part of the program’s success?

 

SB: I’d describe the Waste and Resource Recovery framework as an ecosystem – I don’t think there’s one part that dominates over the others. I think it’s getting all the parts to work in concert with each other. So it’s about having a very strong direction from government to do the right thing. The government has said that we want to achieve these very ambitious targets, and that sends a very strong message. It’s about having a financial and economic tool with the waste levy and that we’ve set a price signal for our landfills and we don’t want landfills to be the predominant processing option – we want people to think a bit more broadly. It’s about having education as well, and that sort of engagement with industry and community so that people are aware and we know how to influence the knowledge, attitudes and behaviours.

None of this works if you don’t have infrastructure, and all this falls apart if you don’t have a regulatory regime that sets very clear standards and has offence provisions that say that if you don’t meet these standards, there will be very serious consequences. And I think, from my end, it’s not just the levy that’s important – although it is a very important aspect – but it’s getting all aspects to work well together that is important. And if we get it all operating together in a very clear and consistent manner, I think that’s when we’re going to get the best outcome.

 

TOS: It will be very exciting to see how it all works, and I’m sure you’re very busy focusing on this now – but as a final question now – I’d love to know – what’s next for the EPA in New South Wales?

 

SB: There are two things that are exciting for us. Looking forward to future population growth, and hopefully less waste generation, and looking at where we should have the next generation of infrastructure. Where should it be installed? Are there areas around the state where we’re short on infrastructure, and how can we stimulate that investment from the local community or industry? So it’s about making sure we’ve got infrastructure in the right locations.

And the second really exciting thing we’re working on – and we’ve just released it for consultation – is a new state-wide education strategy called Changing Behaviour Together. And this is really around building a platform for a conversation with the community at all levels – with local government, industry and residents – and finding out what their needs are in relation to their knowledge, attitudes and behaviours around waste and recycling, and how can we help standardise that and run state-wide programs to focus on that behaviour change that really underpins our investment in infrastructure.

 

TOS: Okay, so there’s a real focus on education and outreach there…

 

SB: Yes, absolutely. I think you can have very complex systems of multiple bins and recycling plants, but it takes an engaged community to make these systems work to their optimum. If people aren’t using these systems correctly, and they don’t understand why it’s important to separate properly, these systems do tend to struggle. And that’s where you get this issue of contamination really raising it’s head. So, I think you really get good bang for your buck from your investment in infrastructure if you have it underpinned by a strong education program.

 

TOS: Great stuff. And we’ll be following the progress very closely – and best of with the program in the next few years!

 

PROCESSOR’S PERSPECTIVE: EXPANDING MARKETS A CHALLENGE

 

THE ORGANIC STREAM: And that was Steve Beaman of the EPA giving us an insight into the NWS’s organic recycling plans. Steve mentioned the need to be very careful in increasing supply of organics to not upset the market (blah?) – and this is indeed something that requires attention. What are the challenges that industry anticipates with this increase, and how big of a task will it be to develop new markets for organic products, compost in particular?

Another key challenge might be contamination rate – with plans to increase kerbside collection, are processors preparing for an increase in contamination as well?

We put these questions to Robert Niccol of ANL and this is what he told us…

 

TOS: Hi Rob, thanks for coming on the show. Just before we begin, can you give us a short introduction to Australian Natural Landscape?

 

ROBERT NICCOL: We began life as a landscape construction company about forty five years ago, and that grew into looking for materials to use in landscape supplies. Pat Soars who owns the company started going over the mountains and getting truckloads of bark, and coming back into Sydney and selling as mulch and what have you. We then got into composting, greenwaste, biosolids and all the urban waste streams that are around nowadays.

We currently compost or process about five hundred thousand tonnes of sorted organic streams at the moment. We’re a very strong landscape and agricultural compost supplies company. You name it, we’re into it – we’ve a very strong consumer market of packaged products, supply chain, bulk material supply and landscape construction – that sort of thing.

 

TOS: Right, and so as a processor on the ground, the government’s plans will have an impact on your business and indeed the industry as a whole. What will this impact be, and are there any concerns in the industry about this increase in supply of organics?

 

RN: The government, to their credit, is spending a quite extraordinary amount of money in industry support and in terms of processing and market development in a whole rage of areas. It’s the best part of half a billion dollars. It’s a huge amount of money, and we will never see the like of that again.

I think there are some concerns about whether or not we can grow the markets sustainably to consume all the additional tonnages. So I think that is a big ask. The government is certainly supporting market development of about seventy thousand tonnes of additional uptake, but the increase of supply will be greater than that, so there’s potentially an issue there.

Whether or not that becomes a problem will really hinge on how effectively the market development money is implemented and spent; what sort of strategies come out; how those markets are developed; and can we get structural change in the bigger markets, like the agricultural sector, which is really where we see the main growth potential being in terms of demand. So, is it going to be a struggle? Yes. I think there are a lot of opportunities for lots of businesses, but the additional tonnes…yeah, it will be a struggle.

 

TOS: What are some of the main challenges, or concerns, you have about market development – what barriers to you face at the moment as an industry that will need to be addressed in order for this to work?

 

RN: Where there’s an issue and a debate that needs to be had – and it has been had some extent – is that you do have different business models, and I’m sure that’s the same all over the world. In our case, we’re one of a number of private companies that started as a horticultural supplies company, and that business has grown and eventually got into what would be considered as the resource recovery and waste sector. But at heart, we are a horticultural supplies company, selling horticultural products.

Then you’ve got the other business model, which tends to be the larger corporatized kinds – those sorts of businesses who are in the waste sector. You know, the real waste driven companies. They don’t come into the market with a horticultural supplies philosophy – they come in with a waste management philosophy, and the two are quite different. Their business model is very much about getting cost recovery at the gate as soon as the material comes in, and then the products of their processing go into the marketplace at a very low dollar value. Whereas those of us in the horticultural supplies tend to have a lower gate fee because we’re expecting to have a value recognised in the output at the end. And they are different models, and there are obvious difficulties with that in the marketplace when you have those two models producing an output that’s competing differently with a different economic structure. That’s a problem.

I think that is something our industry has struggled with and the government has struggled with, and I don’t know that there is a good answer to that. But the difficulty is that when you’re looking to grow markets, like the agricultural sector – and we’re particularly looking at cropping and grazing – where there are more marginal growing sectors anyway, they have some very good years, but they have some very lean years in between. So they’re a relatively low return sector anyway. So you’re going into the hardest part of a market to actually get money out of them, in terms of value for your product.

And the products in those sort of applications are effective, but they’re still competing with fertilisers and bedded down systems. So part of what we need to do is engage in those systems, and get product uptake in those systems. They are inherently a conservative sector, so you need to get those people who have been growing often multigenerationally in a particular fashion. You need to engage with them and give them some comfort that what we have to offer is of value, and it’s sustainable and will work for them with their current cost models.

So we’re looking to actually see, out of the market engagement, the real value of what we have to offer recognised, and to try and penetrate those markets and show the effectiveness of the product. We have to do it at a competitive price, obviously, but unless you break that nexus, that market will never exist. If we don’t get past this first hurdle, where they’re used to using synthetic fertilisers, then it will never change.

 

TOS: Yes and here you mention education and outreach – which are key components to developing markets in New South Wales?

 

RN: I think when you look at the current supplies into those sectors, you have larger, agricultural chemical supplies companies who have been supplying into that sector for many, many years; their data is very good and they have a history of use with those products working well. They’ve engaged well, they have a lot of money behind them, and they’ve been able to set up their supply into that sector, well supported with good data, good technology and good advice.

Whereas we’re stepping into that without the dollars behind a Monsanto type of company. We don’t have those sort of resources and we’re stepping into a conservative area, so the education and engagement, and the extension of the good information and data that we have at the moment…we haven’t been very effective in getting that out. So there will be a lot of people who I think we will get to change – and are probably quite keen to change – but we haven’t yet spoken to them. We haven’t engaged with them and we haven’t explained the case well. So, the education side is very important.

 

TOS: And going back to the increase supply and perhaps another challenge you’re facing: the EPA is focusing a lot of their efforts on educating people about putting materials in the right bins and so on – really getting people to understand the importance of recycling in an effort to keep contamination low. With kerbside collection expanding in the next few years, are you concerned about contamination? What has been your experience so far?

 

RN: We’ve had quite a number of different contracts over the last twent y five years. Often the contamination is an issue given that most of these streams come out of local government. So they’re within a local area, and that local government facility or waste system is the driver for the recovery of whatever the new stream is – when they decide to introduce a green bin and kerbside collection for green and food waste, or whatever it is. If that council or local government authority has an environmental philosophy from top to bottom, where everything that flows from the top down is about closing the loop and understanding that the outputs of these materials will be coming back to our environment, then they see the issue is about contamination and how it affects the value or quality of the product. And they set up really strong and clear systems that are linked to their council philosophy.

When they start, the new services come in and that’s when you have early issues when it’s new to people and they don’t necessarily know what’s going on. If you have a council that sets up a contract, it’s well aware of that and as soon as those issues arise, they’re proactive – they don’t want the contamination and engage with local residents – and generally speaking, those issues evaporate because they’re driven from the council and local community. And someone has a contract to collect it, and the collecting contractor is a really important part of that as well because they’re the ones picking up the bins – it’ll end up coming to us and as a processor, it’s critical to us that we don’t have contamination. But if you have everyone in that loop with the same general philosophy, contamination isn’t an issue, because if you as a resident don’t care and you keep on putting garbage in your bin, they take away the service.

If on the other hand, and we’ve certainly had contracts where that’s not a driver within the government, then it’s very difficult to manage – because as the end contractor, you don’t have the power in the process to stop that contamination coming in, and that becomes very difficult. So it’s very much down to education and I know the state government is engaging very strongly with local government, and that’s absolutely where it needs to be – because they’re the drivers of the contracts; they’re the people who sign the contracts up with people like us, so if they’re not supportive of it and don’t have structures at the end of the day to remove a service if it comes to that, then we’re stuck with whatever comes in the truck.

 

TOS: And the government’s cooperation with industry is another important aspect. So, building up relationships and strong communication channels between them is crucial for success, I imagine?

 

RN: That’s absolutely critical. We’ve run a couple of different grants within our business, and I think personally that the process that we’ve gone through has just been exceptional. They’ve had people within government that understand our sector that we can go and talk to. So if you’re that person, I can go to you and say, “Eleen, this is the grant we’re thinking of putting” and I get very clear guidance, such as, “Yes that’s good, but I’d think about doing that, that and that”, or, “No, it doesn’t fit within the guidelines”. So very quickly you get an answer as to whether the idea you have fits with what they want. If it does, there is an opportunity to get economic consultants in to evaluate the business case and give you advice on whether or not they think economics of what you put forward is logical. After we’ve won our grant, they then have consultants – I think we have about twenty hours of free consultancy after the grant is approved to get through the approvals process and to get thought issues you have in in actually getting your facility built, or whatever it is, once the grant is up. And there’s support after the grant.

I think, really, as a private business, you can’t ask for more than that. It’s been very, very good. It’s a lot of money that they’re spending and it’s a pretty big achievement to get that sort of money out of treasury for our sector, so I think they’ve done a pretty amazing job, really, for the complexity of the programs they’re looking for.

 

TOS: So it’s an exciting time now in New South Wales, it’ll be very interesting to see how it all goes…

 

RN: Oh, definitely. It’s certainly going to be a lot of activity and it will be interesting to see where we are in our sector over the next couple of years, because an extra hundred and sixty thousand tonnes of material is what they’re proposing to generate, and that’s a lot on top of what we’re currently doing.

Organics Recycling in France: How New Compost Standards & Incoming Laws will Change the Landscape

TOS31_Feature Image_Compost_France

This episode corresponds to Lesson 5 of our online course.

EPISODE SUMMARY

On today’s episode, we’re taking a look at the new compost label and quality assurance system designed by the French national network for the collection and recycling of biowaste, Compost Plus. We’re joined by Thomas Colin of Compost Plus who gives us a detailed look at the new system and what it will mean for organics recycling in France. We examine how strict the standards are and how they will be enforced, the reasons for creating them and the issues with the pre-existing standards, how the new system will benefit the French compost industry and the agricultural sector, and the challenges they faced in creating these standards.

We also get an update from Thomas on source separation in France, the new guidance manual developed by Compost Plus and what it will do, and about the new Energy Transition Law – which is currently being reviewed in the Senate and, if passed, will greatly impact the landscape for sustainable organics collection in France.

TRANSCRIPT

 

Compost Plus and the French Situation

 

Q: Can you tell me about Compost Plus and what you are up to in France at the moment?

Thomas Colin: Compost Plus is a network of local authorities all involved in composting and separate collection of biowaste in France. There were six members at the beginning in 2009, and now we are sixteen members, which represent around 1.3 million inhabitants. It is important to notice that Compost Plus is a fully independent association and there is no money from private companies.

All our resources are from members’ fees and the goal of the association is to promote the collection and develop separate collection of biowaste in France. We use different methods, like communication. We communicate on separate collection of biowaste in many conferences and meetings all over France, and we organise every two years specific working days on that field, inviting councillors and technical agents.  We also do a little bit of lobbying; we’re involved in different regulation working groups, and we’re also members of the European Compost Network – which is a lobbying group of European experts with who we share the same vision about the way to recycle biowaste.

And finally we have a few projects – two of them are finished this year. First is a quality assurance system for composting plants, and compost from biodegradable waste. The second one is a guidebook on separate collection of biowaste, giving the reasons why it should be developed and aiming to spread the best practices. There is one project still in progress; it’s an observatory of local policy, aiming to evaluate the economic and environmental impacts of separate collection of biowaste.

Q: Just to clarify – you work solely with municipalities that source separate their organics?

TC: Yes that’s correct, they are all involved in separated collection of biowaste – all involved in source separation.

Q: Can you give me an overview of the situation in France regarding source separation, and composting standards, before your system came in?

TC: In France the separate collection of biowaste is really unpopular at the moment. There is only maybe three to five percent of the population involved in this type of collection. So it was essential for us to write this guidebook in order to demonstrate the feasibility of this industry.

And in terms of the compost context in France: the French quality standards were not sufficient enough for the agriculture industry. They were asking for stronger external control, more traceability, and clearer specification. For instance, there was no clear difference on packaging requirements biowaste compost and municipal solid waste compost, so this was a fear for operators that the user would be mistaken and would lose confidence in the industry, and finally would prefer not to use compost anymore on their farms. So that’s why Compost Plus found it necessary to build this new quality assurance system. It’s called ASQA – the translation in English would be Soil Improvers Selected and Quality Certified.

 

Introducing the New Compost Quality Assurance System

 

QWhen did the work on the quality assurance system start?

TC: The work started two years ago. It was a big collaborative work. All the stakeholders were involved in the project: Compost Plus with its members, but also the ADEME (the National Agency of Energy and Environment) from which we received some funding as well. The Agricultural Chamber of France, which represents all the local agricultural chambers, was also involved. The FNAD, which is the federation representing private companies. A few other associations, like the European Compost Network, and the Composting Farmers of France, and the certification bodies were also involved.

I would like to say that the support of the Agricultural Chamber of France was really important – they brought us a technical as well as political support. Actually two press releases have been co-written and published together, one of them during the last Paris International Agriculture Show. This collaboration was really strategic for the wide acceptance of the project by users, because four years ago the Ministry of Ecology led a similar project of the National Composting Charter, including altogether the urban compost, biowaste, green waste, municipal solid waste compost, but the project eventually collapsed because they didn’t get the confidence of the agricultural industry.

Q: Did the collapse of the previous project make it more difficult for you then to set up this new system and label?

TC: Yes, well, what was difficult was gathering all the stakeholders around the table – the private companies, the agricultural industry, the local authorities, and technical experts as well.

Q: So there are quite a lot of players involved…

TC: That was a lot of players, yes. That was one of the challenges – to get everybody around the table, and finally, to make sure the final document was fully approved.

Q: And that process took two years.

TC: It was two years of work, yes.

QThe quality assurance system has just launched last year in September, so it’s still very new. And we touched on this already, but can you tell me the reasons for making this new label?

TC: There were a few reasons for making this new label. For users, the priority was to give them more traceability, more control, more warranties, and better quality. For operators, the label allows them to secure their outlet, and makes the market more lasting for the future. As I said, it was also a clear way to mark the difference between biowaste compost and other urban compost like municipal solid waste compost.

Let me say one more thing. In relation to the French context, there was a lack of quality assurance systems in France, actually. Most of the plants use ISO Standards, which focus particularly on management, but nothing on the product quality. So the project was to create this integrated system based on both management and product standards.

 

Compost Label Criteria: Just How Strict Is It?

 

Q: How strict is this new system, and the compost label – what criteria did you put in place and what does it cover?

TC: First, the label is open to any plant, public or private, even if it was a public initiative at the beginning, that composts biodegradable waste separately collected. Meaning that municipal solid waste or sewage sludge is not allowed and can’t be part of any product from this label. Compared to what was done before, the label is a lot stricter: there are thirty-six requirements for quality management, environmental management, and product quality.

A big part of the label is inspired by ISO Standards, which means that the quality policy and the procedures are written, the internal communication done, and information is given to operators on the plant. And there are also internal controls done every year to make sure the plant is still in line with the label requirements.

About the product, there is also a threshold for pollutants, in line with the European Eco label for soil improvers, which are stricter than the French national standards, especially on heavy metals content and impurities.

Q: In terms of the operational aspects – what steps will be taken to ensure operational quality in the compost plants, and so on?

TC: Everything has to be recorded: all the composting operations during the process and the composting parameters such as temperature and moisture. Everything has to be recorded and independent certification bodies can ensure that the requirements are respected. At least one external control is done per year, and each product is sampled for external laboratory analysis. There is also internal analysis required, and there is a particular attention given to pollutants that are likely to pass the allowed thresholds. For instance, when a threshold once, the implicated parameters are analysed on all the following batches for one full year. Aside from the agronomic criteria, the organic matter and nitrogen content are analysed on every batch.

Q: Tell me a little bit more about the traceability.

TC: One goal of the label was to bring more traceability, as I said. So, the work on the platform starts by creating input batches. Each batch is followed during the full process from the first stage to the final product, and at every stage of the process, the operators have to know the exact composition of every batch. That means that each kilo of input or output is recorded.

 

Dealing with Costs and Expectations

 

Q: Were there any stumbling blocks or issues you had in relation to designing the quality control aspects of the system?

TC: Well, the main challenge was to create a label complying with farmer’s expectations and operator’s limit in the field. So we had to deal as well with the existing rules and practices that sometimes can be hard to change, even just a little bit. So we tried not to revolutionise everything, and to retain most of the best practices already implemented on the field.

One challenge, as well, was to contain the implementation costs of the label. That is why operators have to do part of the control – I spoke about internal control already. So they are doing that internal control and sampling the product. And as the label has some similar requirements to the ISO Standards, we made it fully compatible with them. Thanks to this the implementation costs are reasonable, I would say. Even more for operators already ISO certified, because when the certification body is at the site, it can control parts of the two systems at the same time.

Q: So it ends up not costing the operator as much in that case…

TC: Exactly, so that is why I call this label an integrated label. When you get a contract with a certification body, this label will cost a lot cheaper for operators already ISO certified.

Q: And how has the reaction been so far?

TC: Well for the moment, five plants are doing the work to be certified. Maybe the first certification could open between April or May, but for the moment we haven’t done any communication – we are waiting for that first certification before making any conclusions.

Q: Can you tell me more about who will benefit from this new label, and how?

TC: Those who benefit will be every stakeholder of the industry. Users will benefit from this label because it gives them more traceability, more control and more quality. Operators will benefit because it secures their outlets. Even, I would say, by extension the consumer who is buying food products grown on farms using certified compost, and finally as well it benefits the national authorities by increasing the quality of the national market.

 

The Question of Biowaste From MBT Plants

 

Q: We mentioned before the trouble you had to bring all the stakeholders together around the table, but you’ve had a few other issues too, like deciding whether or not to include mechanical biological treatment plants (MBT) plants. Would you care to talk a little more about that?

TC: Well that was one of the questions, whether this label should include the municipal solid waste compost from MBT plants and other sludge sewage compost as well or not. In the end we decided to make this label apart, because Compost Plus members are not familiar with those plants, so it was too complicated for us to imagine creating a label integrating all urban compost. We didn’t want to make a label that confused the user, so it was better for us to separate this initiative.

Q:  Was there any pushback on this decision, or did you have any trouble defending it? 

TC: No, actually they understood this position and today they are working on their own certification label as well on their side. So we’re happy because our initiative gave them the same idea and hopefully with their label they will try to increase the quality of their compost.

Q:  Of course our stance is that source-separation is the best way to go for organics recycling, but are MBT plants popular, or gaining popularity, at the moment in France?

TC: I will say that for the moment the local authorities are waiting for a signal from the national authorities. There are no clear national strategies on how to recycle biowaste. Some local authorities chose to do separate collection of biowaste, others chose to do MBT – but there are few of them, and for the moment most of the local authorities haven’t done anything yet.

 

Source Separation of Organics & The Energy Transition Law

 

Q: This is a good transition to talk about what’s happening in France more generally now with organics recycling and source separation. It’s an exciting time at the moment in France – can you tell us more about why?

TC: Well there is a big regulation project called the Energetic Transition Law. In this initial project – supported by the new Minister of Ecology – there is one goal, which is to generalise source separation of biowaste by 2025. So this will be the strong signal I was talking about for local authorities to favour separate collection of biowaste all over the country.

It will also be a really important measure when you think about the international context of climate change and also in contemplation of the next 21COP held in Paris in November (a summit on climate held in Paris at the end of the year), and this measure will be strong contribution from France to reduce our environmental waste impacts. Because we have to know that thirty percent of human methane gas emissions are from landfilling.

So about this Energetic Transition Law – in a few days the Senate will examine the law, and their conclusion should be delivered in the middle of February, so in two weeks, maybe the national situation will totally change.

Q: You’re busy right now talking to the senators and so on about separate collection to spread the word, and this brings me to the source separation guide book (or manual) that you’ve produced (published 5th February). How long has it been in production?

TC: It was also two years work, actually. It’s a book that gathers many, many successful experiences from all around France about source separation of biowaste. There are more than twenty local authorities that have contributed to this guide. And we will officially publish on the 5th of February, so then we will widely spread it to local authorities.

Q: Can you tell me why there is so little source separation in France at the moment, is it just a question of economics or is there much opposition to it?

TC: I wouldn’t say that there is many people against source separation of biowaste in France, but there are still the same people and local authorities defending – and that’s normal – their investment and what they have done. So we can’t say that France is MBT, because some of them are, but some of them are in favour of source separation of biowaste.

Q: Right so there are just a lot of different voices at the moment.

TC: Yeah, it’s a lot of different voices, but most of the people are just waiting for the conclusion.

Q: But municipalities might gain the confidence to start source separation schemes now thanks to this guidance manual?

TC: Yeah that’s true. That is one of the goals of this manual to show the local authorities that source separation of biowaste works everywhere – in urban areas as in rural areas. And yeah, we want to demonstrate that it is working and it’s feasible technically and economically. Because most of the time the argument is that separate collection of biowaste costs more than, for instance, MBT. But this guidebook shows that the twenty local authorities can contribute to this book haven’t got more costs than the national average.

The Future For Compost Plus and France

 

Q: It will very much depend on what happens with the Energetic Transition Law, but what is the focus for Compost Plus then in the next few years?

TC: Well first of all our next goals will be to make sure the ASQA label is implemented everywhere by local authorities in as many plants as we can. And in relation to the Energetic Transition Law, if the law is in favour of source separation of biowaste, we might have to focus on how we can educate new local authorities in the way of developing source collection of biowaste.

Q: It will be a very busy time, then! And it’s a very busy time for France, too – I’m sure you’re excited for what the future holds.

TC: Yeah, that’s true. The situation can totally change in a few days, and I’m sure this is because of this unclear situation that there is this debate in France. In all other countries in Europe, the national law is clear so there is no debate, and then source separation of biowaste is well developed. As we see in Germany or in Italy, when the national strategy is clear, the local authorities know that they are supported, so it’s easier for them to…to

Q: …to make the change…

TC: To make the change, exactly.

An Approach To Expanding Commercial Composting Operations

TOS_25_Composting_Facility_Expansion

This episode corresponds to Lesson 5 and Lesson 6 of our online course.

In this episode we’re in Los Angeles talking to the project manager of the Inland Empire Regional Composting Authority Jeff Ziegenbein about how best to expand your composting facility without compromising quality or risking your business.  We discuss with him the reasons why composters may need to expand, the technological advances that can help with processing and odour control, how to use a phased approach to growth in order to secure financing and to maintain production quality, tips on dealing with regulations, and much more.

Thanks to If You Care for making this episode possible.

If You Care Certified Compostable Bags are made from potato starch from starch potatoes, blended with a fully compostable polymer, and are polyethylene and plasticizer free. Their potatoes are grown for starch only unlike corn which is grown for food. Their potatoes require forty percent less land than corn and no irrigation. For more, visit their website.

TRANSCRIPT

New Mandate And What It Means For Composters

 

Q: In terms of closing the loop, it is often preferable to have a larger number of small-scale composting facilities to ensure that organic materials do not have to travel far from their source in order to be treated. However, today there is still a great need for larger facilities, and composting facilities often face scenarios that require them to scale up their operations. Jeff, you mentioned before we started that there are changes taking place in California that will see more composting facilities needing to expand. Can you elaborate on this and tell us more?

JZ: California is going through a huge change. We’re mandating the organics away from landfills, and it’s a very ambitious goal. CalRecycle, which is our Integrated Waste Management board here in the state, has announced that they have this new paradigm, saying they want to move out of the landfill. They want to disincentivize and do whatever they have to do to pull those organics out of the landfill for higher and better use.

But the way this new assembly bill reads, some of the activities that are currently considered recycling will no longer be considered recycling – specifically Alternative Daily Cover for landfills. We’ve got a whole bunch of green waste and other organics going into landfills that are not being counted as disposal, but rather as recycling because it’s being used as Alternative Daily Cover. Under this new assembly bill, this no longer will count. We’re essentially doubling the amount of recycling in a very, very short period of time. So the impact to the organics world in California is going to be very profound. Most of us in California, and others I talk to in the US, view that what happens in California tends to trickle outward across the country and sometimes far beyond, so everybody’s watching how rolls out very closely.

I say that because when composters are facing different scenarios that may encourage them to change or expand their facilities, this is a big driver. Right now, California composts almost six million tons of organics, so we in the organics industry are expecting that to double to about twelve million tons in about five years. So that’s going to require more facilities, more markets, and infrastructure. I think one of the big things that we all need to be aware of is that it’s going to require diversity, so we’re going to have to be creative. We’re going to have to open our minds up a little and understand that it’s not just one technology, one scenario or one application that’s going to require a lot of different varieties. So, small backyard operations, community operations as well as very large regional facilities are all going to have to be constructed and expanded to satisfy this new mandate.

Q: So one of the major reasons a composting site might need to expand is an increase in feedstocks. But how about regulations? There are very stringent regulations in California that make it difficult for smaller composting sites to get off the ground…

JZ: That’s true. California is a big state, but I one of the things that’s common across the state is the challenge of siting facilities. We have a population and a state that doesn’t usually like facilities to be very close to where their residents are, but the further you move away from where your populations are, the more transportation costs you have. So we always try to build as close as we can to where the materials are generated, but in our state we have a lot of stringent regulations around water, air and nuisance that do require higher technology than I see in other places in the country.

For example, the facility that I’m operating here in Southern California – the Inland Empire Regional Composting Facility – this facility actually cost ninety million dollars to construct. And that is a very large price tag for any composting facility; it may be one of the most expensive ones in the world. But the reason why it’s so much money is because it’s right in Los Angeles. It’s in an urban area, and it’s in an area that is very heavily regulated by an air district, because LA is not in compliance with the clean air act and is also heavily regulated with water and with lots of things.

So in order for us to be compatible to build a facility like this in this type of an area, it required a lot of engineering and a lot of infrastructure. The good news is that we did get it built, we did get it permitted and we’re able to operated it at a very competitive cost, but the only way we’re able to make all that work is by a heck of a lot of volume. In the case of this facility, we’re operating over two hundred thousand tons every single year, and that’s the reason why we can make this work. It’s not always that easy: if you build a small or a medium sized facility with this type of VOC and odour control (VOC’s are volatile organic compounds, which are regulated in this district), and you don’t have a lot of volume to spread those costs over, you can price yourself right out of being a possibility. So we see that challenge over and over again in the state of California, and I’m sure that’s a common problem across the world.

Q: So if regulations are very strict, it may force composters to invest in building covers or in more expensive technologies, which in turn would require them to scale their operations.

JZ: Yes, and the good news that in two major areas in California have air rules that require the removal of VOCs, and when you remove VOCs you also have to remove most of the odours in the air streams that are remitted for composting facilities. So just by surviving in these air districts, we’ve learned a lot as an industry; what does work, and what works on a big scale, so we try to share that information and teach others that these technologies do exist – they’re fairly predictable in how they operate; I’m really talking about biofilters. We do have a pretty good understanding about how these work and we can use them in lots of ways; in ways that are very expensive, but also in some ways that aren’t quite so expensive. So we view that there’s some hope that we can site more facilities in California and be compatible with the air rules and the neighbours.

TECHNOLOGICAL Advances In The Composting Industry

 

Q: Let’s talk about technologies. A big factor here is that within the last 20 years we have seen an increase in the amount and type of feedstocks being accepted into composting facilities (biosolids, paper sludge, food scraps…). Due to the increased complexity in processing the material and controlling odours, it’s spurred on the need for more sophisticated technology to handle all this. Jeff, what rare the technologies that are worth investing in today to handle odour, and so on?

JZ: For odour control is often a biofilter, and a biofilter is essentially in most cases a wet pile of wood, and the beauty of that is it’s a wet pile of wood and most of us can figure out how to operate those. It’s not that complicated, you don’t have to have a full-time engineer with a bunch of fancy instruments, it really is just a pile of wood, and we have to maintain it for moisture and make sure the air is moving through it appropriately, and size the pieces of wood appropriately and things like that. But biofilters work, and the good news is that we can copy this and teach people how to do this, allowing them to build these things fairly inexpensively.

So for odour control, and for compliance with these air districts, a biofilter is a very good tool, and we’re getting more and more confidence with using them. More recently, there’s been a couple of variations to biofilteration, including some covers where they have permeable tarps that you can put over piles that have a bunch of surface area in the tarp so the water molecules will collect in the surface area and the air passes through and transformed similarly to how it would be in a biofilter. Those seem to work pretty good as well.

The Association of Compost Producers, a non-profit trade organisation that represents most of the composting companies in the state, developed an alternative to all those I’ve just talked about, where a finished compost layer is placed over a compost pile, and then air is blown up through the compost pile. And as the air passes through the finished compost layer, that actually works as a biofilter. So that’s even cheaper yet than securing new wood and having to size it and moisten it and so on. And so that was done in the San Joaquin air district that has very stringent air regulations.

So the Association of Compost Producers representatives and some others put together a pilot project with a grant, and demonstrated and measured the air omissions from these piles using the lowest cost technology, and it actually worked very well and got about ninety eight percent removal. So that may be something that really helps facilities deal with odour removal and VOC control with even a lower cost method. That same technology is being tested in the South Coast air quality district and other districts in California to verify it and see if it can be repeated in another air district. And if it can be, it may be adopted as a best management practice for these districts.

Q: Is there anything else on the market right now that you see as promising or worth investing in?

JZ: The most exciting things that I have seen is some of the technologies in the tarps that can actually process the odours and VOC control. I’ve seen quite a few of these work and I like the simplicity of just throwing a tarp over a compost pile and having these automated systems control the air flow and temperature and so on. So some of these kits for making a compost system are pretty interesting, and as we get more and more experienced, I can see them becoming an easy way for someone to start up a small or medium sized facility. It’s just a tarp and a probe that has an oxygen sensor and a thermocouple, and it goes to a small motherboard that controls the fan. I like the thought of that, I think things like that have a lot of promise.

Q: Your facility is a completely covered facility, is that right?

JZ: Yes, the Inland Empire Regional Composting Facility that I manage is a converted warehouse. It’s actually an old Ikea warehouse that’s almost five hundred thousand square feet, so it’s a very large warehouse that has conveyors and wheel loaders and things like that operating inside of it. So all of the emissions from the compost piles are trapped within that building and then exhausted out through the biofilters. The amount of control of emissions is pretty extraordinary, actually.

Q: Because of this, would you say that covering your facility or using in-vessel composting would be the best way to go when dealing with such stringent regulations or being close to residential buildings?

JZ: I think it depends on where. We’ve looked at possibly working with other people on building additional facilities, and almost every time we halfway serious about it, we end up envisioning a covered, fully enclosed facility, due to the reasons I mentioned before. The only way we really feel comfortable in an urban area on a very large scale was to do the complete enclosure. I think if you’re in a different area and not so close to Los Angeles for example, then that’s when you can get into some of the hybrid technologies that I mentioned before.

 

 Challenges When Expanding Operations

 

Q: I’d like to focus on the process of expanding a facility. What are the key issues or challenges to take into account when planning your expansion?

JZ: I think the big challenges, and not in any particular order, would be environmental regulations – and that has some cost impacts – markets, and definitely technology to make sure it’s clean enough to be marketed and processed, and probably transportation.

Those seem to keep coming up over and over again when I talk to folks about expanding or building new facilities. But markets are always a major concern. In some areas less than other areas, of course, but in Southern California which has a tremendously robust composting infrastructure – we’re currently composting over three million tons down here – we need to expand markets.

Q: Market creation seems to come up again and again, and it’s something we talk about quite often. It is complex and it’s difficult for the composter to handle it by themselves of course, but what would you recommend to composters, then, as a strategy for expanding the markets?

JZ: Building markets is a long term process, and it needs to have the mainstream of people realise that it is important not to have naked soil and to just throw water at naked soil. We do that all the time in this state, and I’m sure across the world. So, getting that message across is very, very important. And in California at least, with the Association of Compost Producers, we’re working on service announcements, we’re working with our water distributers, creating model ordinances requiring soil preparation before irrigation permits go down…just educating people that it’s wrong not to treat your soil. You shouldn’t just throw a bunch of water on sand and waste this drinking water.

In order to market, it takes this broad approach. And then on top of that it takes a local approach. You need to work with your customers and tell them why they need more, how to expand their market, what their messages need to be. We work with schools in trying to get the message to the children that you need to put compost down. So it’s all of those things.

 

Using A Phased Approach

 

Q: Another big issue for expanding a facility is in securing funding and putting in place a workable strategy that will give confidence to lenders and also yourself when expanding. How would you advise composters to start planning their expansion with these issues in mind?

JZ: Yes, for example, to fund a new composting facility in California and get a bank to come up with a bunch of money so you can build your facility, they need some assurance that it’s actually going to work. So if you just have this vision of this huge facility, a lot of times folks will try to go get put or pay contracts, and build these models and things, but banks sometimes aren’t satisfied with that, and that can make the cost of money pretty prohibitive.

One of the better models is if you can design a facility so you have this expandability to it and you can do a phased approach, then you have a lot better shot of success. You can have, say, a receiving structure that’ll take it in a little or a lot of material, but that’s usually a fairly inexpensive part of your process, and then you can feed these different operational trains for one through four phases. And the facilities I’ve seen use that kind of process – that’s the smartest way to go if you can do it. In other words, if you can get funding for phase one at twenty-five thousand tons and you can make the business case work, then you can prove that out. And by the time you get to phase two your economies of scale are so much better, and it really gives you an opportunity to expand a facility.

But then you’re not starting right at this maximum best case – there’s just a lot more risk for failure when you do it that way. If we’re talking about borrowing, you need to demonstrate in a very professional way what’s working and why your expansion is going to assure that you are going to pay money back. So when you’re doing performa on your business models and having enough comfort level in there and enough conservatism in there that the numbers are real and you can verify them, that’s the key. It’s very tough to design a facility and have it actually work exactly how you estimated it would, so I would be as conservative as you can stand, and then if you have a bit of a track record and your numbers are real, I think you can get the funding that you need. It can be done, I see examples of it all the time, but you do have to put together a real performa, and it has to have some sort of backing to it.

Q: Yes, and in the US at the moment, financing is a very tricky thing to get these days what with state grants and loans having been decreased over the last ten to fifteen years. Is it easier for a composting site that has been running for a while to secure capital in order to expand?

JZ: Well I think it might be easier. I think if you go to a lender and you have this track record, and then this proposed expansion, I think you have a little bit more confidence from the lenders. And there is also some grants currently, with this new paradigm as CalRecycle likes to call it, there is some funding for facility expansion. So there is some money available that folks are competing for to expand their facilities, and that may give lenders a little bit more confidence too. I think there’s a little bit more money than there was, say, five years ago. I don’t think it’s as healthy as it was ten years ago, but it’s certainly better than it was recently.

 

How To Tackle REGULATIONS

 

Q: Let’s move onto regulations. It’s always going to be a long process to go through when figuring out what regulations apply and how to comply with them, and we can see even from our discussion today that they have shaped the composting industry and where we go with it. What advice would you give to composters on this front, and how can we best get on the right side of the regulators?

JZ: : I know this is a regional answer, but again we’re sort of a case study: in California I think it’s very important to be involved with a lot of these changing issues. Specifically the Association of Compost Producers which is this trade organisation, it has a seat at the table. We have a lobbyist sitting in Sacramento, and we are the state chapter for the United States Composting Council, so we are working with Caltrans and CalRecycle and assembly people, and the water board and the air board – all these different variables that are impeding the growth and expansion of the compost marketplace. It’s very important to get involved, and it doesn’t cost a lot of money, but you have to maintain involvement and get to know what’s going on.

For a long time the compost industry has been a fragmented group of companies who saw each of their own projects as an individual island, but because these regulations have become so dynamic and impacting, all these groups have joined together for this common cause to make sure everybody understands that compost is the highest and best use for this material, that we are a real industry with a real group of professionals, that we are involved and are funding staff to make sure we have a seat at the table. I think that’s probably the most important thing folks can do. Just get involved!

I think that raises the bar, raises the standard, it makes common standards, it keeps everything as professional as possible, and that’s really one of the biggest keys to moving forward successfully

Q: So your key advice is for people to just get involved, and then maybe we can influence how regulations are being created to support composting better.

JZ: Absolutely.

 

Managing ODOURS and QUALITY CONTROL

 

Q: In terms of managing the facility during expansion, it can be quite a lot of work to maintain your quality control and odour control as it gets bigger and bigger. What steps can we take to expand without losing quality or risking odour problems?

JZ: Yeah, that’s tricky. It is definitely tricky, and it’s not usually a linear change. If you have some sort of control system and you do a forty percent increase, you can’t just increase your control system forty percent and call it good. It’s more complicated than that. You have to be conservative when you’re expanding a facility for the reasons you just mentioned. The cost is so high; if you have a successful operation and you go to do a forty or fifty percent increase and you kill your whole project – that isn’t anything that you want to have happen. So I think you nailed it; I think it does require a lot of planning and research and control measures to make sure that when you do make these changes you’re not jeopardizing your entire project.

And we’ve seen that happen, it’s very unfortunate. You know, you think “this works, so if I do more it’ll work better”, and sometimes that just is not the case. So you have to build in a lot of safeguards when you start to expand operations.

Q: And what would these safeguards look like?

JZ: Well, there are a lot of professionals – not that you necessarily have to go and hire a full engineering firm – but there are some very competent professionals that can help measure and quantify some of those changes. For example, what’s going into a biofilter? What is the cubic feet per minute and concentration and the effectiveness of your biofilter? And if you want to expand to some X percentage greater, what would your empty bed retention time and biofilter need to be, and therefore your square feet? There are a lot of folks who can really help build in some of these control measures and then give you a safety factor.

That’s really the take on what I’m trying to say. I think you really need to be conservative when you start designing expansions. For example, if you wanted to expand by fifty percent you might phase that in. Start with your odour control device, and then do incremental increases in your throughput – that way you’re not destroying your whole project. So if you doubled your odour control device, but then only increased your throughput by half, then potentially you have this bit of a cushion before you jeopardize your project.

Q: So you need to go slow and steady.

JZ: I think it’s pretty important. Projects do get killed in California; it happens. If the neighbours are against the project, the regulators start to fall out of favour with it, and the local enforcement agencies – it’ll kill a project. There’s a lot at stake; it’s expensive to build these things in California, you do not want to get it shut down.

Q: And this applies to the rest of the world too.

JZ: Of course.

TECHNOLOGY – Simple Is Best

 

Q: In terms of picking out the right technology for your expansion, there is often a tendency to source the highest functioning technology available, because it’s cutting edge and might be easier to sell when looking for grants, but that’s not necessarily the best option…

JZ: Well I think you’re right, and we’ve seen examples of trying to fully automate composting processes, and  we end up modifying that somehow and doing as much labour or more trying to live with whatever savings we thought we were going to get from this automation.

Personally, I take whatever is the cheapest and the dumbest first and work up from there, and ask why you can’t do this or can’t do that. Really low technology or inexpensive technology with the finished compost biofilters thing that ACP did is very good. It’s not going to work everywhere, but that’s one of the ones you’d look at early on. You know, “can I do this with a windrow? Oh I can’t because f the air rules. Okay, well can I do this compost blanket technology? Oh, I can’t because there’s a retirement community three miles away. Well okay, can I use a cover? Oh, I can’t because of – whatever”.

So you have to start ruling some of these out for whatever reason, and then ultimately maybe you get to where you have a fully enclosed composting facility, because that’s really the only thing that’ll be compatible in the region that you’re looking to build one. So again you need to start simple and cheap, and then work backwards.

Final Words Of Advice

 

Q: Is there one piece of advice you could give all composters out there who are looking to expand no matter where they’re situated?

JZ: I would certainly recommend looking at other facilities. We have a lot of good examples around the world of facilities that work, and go look at them. It does not cost that much; most facility operators are happy to show off what they’ve got that works. So take a look at it. Find out why it works and but lunch or something, and spend enough time that you can get the real challenges out of them. You know, ask the questions: what are your biggest challenges? Why would you do that again? And those type of things.

Learning from other’s experiences is probably one of the most valuable tools that we as an industry can use. And through associations like the United States Composting Council etc – we have these meetings where all these guys get together and talk about their projects. I think that this is a very important step.

Q: Do you have any final words before we go?

JZ: I’ll just say that as our industry matures, that organisations like the United States Composting Council and others like them around the world, and Association of Compost Producers in California – and Compostory.org – things like this are really important, and I think that the industry needs to stay informed and stay involved, and share what they know, and listen to what others know. And that’s how we mature as an industry and grow.

Choosing Compostable Plastics for Your Program: Standards, Labelling & Testing Protocols

TOS24_Compostable_Plastic_Biodegradable_Composting

This episode corresponds to Lesson 5 and Lesson 6 of our online course.

In this episode we navigate the complex and sometimes confusing world of compostable plastics, addressing the current issues and main questions on this topic. What is compostable as opposed to biodegradable, and why does it matter? What standards and testing protocols exist for compostable plastics and are they in line with what composters are experiencing on the ground? What are the pressing issues that composters have in dealing with these plastics, and how can we improve compostable plastic labelling in order to safeguard against contamination of other plastics? We pose these questions to our two guests: Chair of the Working Group on Biological Treatment of Waste at the International Solid Waste Association and member of the Italian Compost Association (CIC), Marco Ricci (Italy), and waste diversion expert Hilary Near (California, USA).

Thanks to Biolice for making this episode possible.

Understanding COMPOSTABLE PLASTICS

 

Q: There are a lot of different types of plastics out there all with slightly different names and properties and it can get quite confusing. Let’s help our audience understand the focus on compostable plastics here, as opposed to biodegradable. Marco, can you give us a definition and clarification on what compostable plastic is, compared to the other types?

Marco Ricci: A compostable plastic is a plastic that is in some way compatible with the composting process, while a biodegradable plastic may degrade under microorganism effect but is not compostable. Normally compostability has a set of requirements which is larger than the one of biodegradability. This is the basic definition. That’s why many experts in this field and also a lot of NGOs started to talk about compostable plastics since about ten, twelve years ago so to avoid any misunderstanding.

Q: So there’s a larger set of requirements needed to be passed for a plastic to be deemed compostable. Hillary Near, do you agree with this definition?

Hilary Near: Yes and I do a lot of communication around behaviour change and with businesses who are making these choices, and I try and simplify it and explain that compostable has a time frame and environment attached to the word, whereas biodegradable doesn’t have any criteria really, and so anything can be biodegradable, including your leather shoe.

 

Our current STANDARDS and ASTM REVISIONS

 

Q: Let’s talk about the requirements and standards that are in place at the moment for compostable plastics. Marco, can you tell us what principle standards exist in Europe right now?

MR: The main standard is the EN 13432 standard of the year 2000, and it’s a standard for certifying compostable plastic. The standard has four requirements, which are: biodegradation of plastic in a definite amount of time and to a specific amount of matter; disintegration, which means we must non-distinguishable fragments in a definite period of time; toxicity – the absence of eco- toxicity in finished compost; and safety requirements. So, the material or compost that is obtained by using these plastics that are in-line with the standard must sustain plant growth. So they are the four requirements.

Q: This European standard is currently known as the most demanding and we strongly recommend complying with this in Lesson 4 of our video course. In the US we have the ASTM standard – which lays out similar criteria for compostability, but there are differences between the two. The ASTM standards are now being revised to be more in line with the European Standard, and also to sync better with the reality on the ground for compost site operators. Hilary, can you give us more information on what is happening with the changes?

HN: Currently the guideline is the lab testing, so there are no field testing protocols, but to your point earlier, the ASTM is working to revise the disintegration test method with two time and temperature profiles that are hopefully going to better replicate the actual field composting conditions of the products that they’re exposed to.

The reality is that the composting process is a very unique and varied process, and it’s very diverse across the United States in all the composting facilities that are accepting this material. So in order to hopefully reflect that and also address any operational impacts of these products on commercial compost facilities, the ASTM is working to revise that and to reflect better the commercial composting facilities situation.

I’m not on that working group, but many of the members who are also on the US Composting Council Task Force on compostable plastics are represented in that ASTM working group. We’ve worked with at least four compost facilities who represent more of an open windrow and a longer with lower temperatures, and then the second time and temperature profile is a shorter process with higher temperatures. So those are hoping to replicate better an aerated static pile and an open windrow composting process. And then apply those eventually to the ASTM standard to give guidelines for which products to work in which facilities.

Q: So at the moment the standards and testing protocols aren’t really in line with what composters are experiencing on the ground?

HN: Well there are a lot of questions about that currently, and that’s what the US Composting Council Task Force is hoping to reconcile and harmonise the lab with the field experience, as it sounds like the Italians are doing as well, given their extensive distribution of some compostable plastic products. So, we are also addressing that concern by reworking the ASTM method, but other composters have had different experiences. Some composters see different products possible remaining after their process, and some don’t. So it’s really anecdotal right now and there are only several composters who are testing products individually in their processes.

Q: And apart from the field testing aspect, are there any other differences between the standards worth mentioning, and are they being revised as well? 

MR: Well, this is a good confrontation because as far as I remember, one main difference between the European standard and the ASTM standard is the requirement for biodegradability. If I remember correctly, the European standard requests a biodegradation – the conversion of the organic matter to CO2 – of ninety percent in about ninety days. While, if I’m not wrong, the ASTM standards has a lower requirement of about sixty percent. Maybe Hilary can confirm or correct me on that?

HN: I’m more familiar with the field testing situation, but that portion is not being revised. But I know that the time frame is one hundred and eighty days, and it does have less stringent sieve protocols for the resulting material that can be remaining after the lab testing.

 

Discussing Testing Protocols

 

Q: Marco, can you tell us what testing protocols are out there at the moment in Europe, and how effective they are?

MR: There are three main protocols for testing and assessing compostability in Europe. All of them refer to the European standard, obviously. The first one is the Vincotte standard – it’s probably the most well-known one. Then we have the German DIN standard. And the third standard is the one which was created in Italy, and it’s the compostable CIC standard. CIC is the Italian Composting and Biogas Association.

Obviously they have to satisfy the same criteria at the EU level, but there are some differences in the testing. For example, biodegradability and disintegration is tested by the Italian standard on a full-scale plant. So we’re running our tests in existing composting plants, while other standards normally rely on lab testing – so, on pilot scale plants. This was one of our decisions to be sure that the material  effectively biodegrades and  disintegrates when we are confronted with industrial plants.

Q: There is no call to make any revisions to them?

MR: Actually, our tests are strict enough, so we’re not demanding for stricter tests. Normally we verify that ninety percent biodegradation happens in about ninety days, which is a timeframe that complies with the standards we have in Italy for getting a mature compost – in an industrial plant, obviously. We’re talking about industrial plants, not about home or community composting.

Q: Can you tell me then what you hear from compost site operators in relation to the standards or any issues they might have in this area – what’s been their experience? 

MR: We have to first make a distinction: the most common

compostable plastic to be found in Europe are bio-bags – bags used on purpose for separate collection of biowaste, and especially for food waste. This is a long-standing tradition of about twenty years. The first bio-bags made of compostable plastics were put on the market in the mid-nineties I would say. So this is one kind of item, and then we have other kinds of items. In any case, in countries such as Italy, Spain or the UK where this kind of bioplastic is very well known, compostable plastics do not pose any problem to the industrial plants.

The complaints are that, first of all, consumers sometimes misuse traditional plastics, or so-called biodegradable plastics, and use then incorrectly for separating and delivering biowaste. The other complaint is that there are some fake bioplastics on the markets, and these are creating some problems. Even though normally where separate collection is done on the curbside – or door-to-door – theses kinds of effects are of minor problems because the total amount of non-compostables that reach a composting plant are well below five percent in weight.

It might be different if we have rigid compostable plastics – so, rigid packaging. In that case, some composting facilities need to somehow restructure their process chain, since they’ve been planned for treating biowaste, and suddenly other kinds of waste items arrive. So, maybe they need some kind of shredding or sorting, and so on.

 

GREENWASHING and CONTAMINATION – the Composter’s Experience

 

Q: If one of the biggest issues is that non-compostable plastics are entering the stream, I’m sure this makes it very difficult to identify and sort compostable plastics from other types of plastics at a site?

MR: Yes, it is challenging, especially because it’s challenging anyway to sort out a bag at a composting plant. There is actually in my opinion (and I would like to know what Hilary thinks about this – another player here that is important. The first player is the waste producer, or the consumer – the one who is doing separate collection. But the second player in this chain is the collection service.

Once the collection crews and companies are somehow advised or bound to the fact that they have to guarantee the highest quality of the biowaste they collect, these people can then help enormously in sorting out critical spots in cities and neighbourhoods. And door-to-door, or curbside, collection helps with this because the collection crew has the ability to not empty a bin where incorrect bags have been used for source-separating organics.

HN: Yeah, I agree and that is definitely an opportunity in the United States. Some of the concerns are around the fact that we often have automated curbside collection, so the drivers aren’t even flipping the lids or able to monitor the material in the containers. But there is a best practice among all the material stream – the recycling, and composting – to leave messages or communicate to the customer that it is a priority to source-separate appropriately. So many haulers will give that feedback to their customers.

I’ve heard from composters that we’ve interviewed that [it’s good] when they have integration: as in, when the composters or sometimes the hauler have relationships with their consumers and can give them guidance on even which products to buy. But then there’s other communities where they’re accepting waste from many different haulers and they just don’t have the capacity to give that kind of feedback. So they’re dealing with higher contamination a lot of times. But that is definitely an opportunity to address all sorts of contamination that composters are dealing with.

 

CONFUSION In The Marketplace – EDUCATING Consumers

 

Q: Marco, you mention the consumer’s role in sorting the plastics, but this can be tricky when there is so much confusion over what’s compostable and what’s not. How can we ensure that the different types of plastics are easily identifiable for consumers as well?

MR: We have a lot of experience with that in Italy and in other European countries. A lot of advertising and information activities have to be done to be sure that consumers can distinguish correctly compostable plastics from non-compostable ones, and the existence of certification labels helps enormously with in that way.

The Italian Composting Association (and also the Italian law) strongly advise consumers to look for the certification label – one of the three main ones existing in Europe – and make sure they are to be found on bioplastics and especially on shopping bags made of bioplastics. According to our experience and common understanding (also exchanging views with other European composting associations), these labels can help consumers enormously to identify the correct bags.

Q: Hilary, I presume there has also been problems in the US with people knowing what’s compostable and what’s not?

HN: Yes, there are definitely concerns. Although, the BPI logo is gaining recognition and was recently revised to include more specifics about what it means to be compostable, including some more caveats about checking with your local agency or waste management provider to determine whether they accept that material. It really is a regional issue right now and the best information is given to consumers by the local municipality or their local composter.

There’s still concerns and there’s still confusion, and one of the opportunities is that BPI has changed their logo and it’s been incorporated into the new printing of some of the products. And on one of the working groups on the US Composting Council recently helped to revise a labelling standard that many of the stakeholders who are manufacturers have all agreed to try and incorporate into their product distribution and labelling; so that includes things like labelling both the packaging and the product as clearly as possible with green or blue labelling and the word “compostable” – again reiterating that you should check with your local composting facility for further information about whether they accept them or not.

Q: To clarify for our audience, the BPI is the Biodegradable Products Institute, which is one of the entities in the US that regulates the use of the word compostable and maintains the best labelling program for compostable plastics in North America…

 

OPERATIONAL Impacts and Managing CONTAMINATION

 

…And Hilary, you’ve been working on a project in San Jose, developing a field testing protocol with the composters there, and you interviewed 15 different facilities who were testing these plastics. Can you share with us the other kinds of issues they had?

HN: The most common issue is just contamination in general. When we talk about compostable plastics, I think it’s important to address the fact that composters are being asked to accept a larger variety and more organic material; which is great because we’re diverting more of it from landfill, but in that case there’s still a need to continue education and address contamination issues with conventional plastic film and especially glass that effects the end product.

Q: So again it seems that contamination from other plastics (and glass too) are the main issues in the US. Marco, is this the same for composters in Europe, and how are we dealing with it?

MR: Yes, it is. Again it depends very much on where they receive the waste from. Obviously the most risky thing is to receive non-compostable plastics and to get them into a composting plant – especially because we have areas where composting plants do not have any sorting devices before mixing the biowaste together, because they expect the receive a very clean biowaste. So in that case they might be in trouble.

That’s why most composting associations in Europe regularly do sorting analysis on the biowaste and quality checks on the compost, so that they have an overview of what’s going on. CIC, the Italian Composting Association, runs about five to six hundred sorting analysis every year, and about two hundred and fifty to about three hundred compost analysis every year on the different composting plants located in Italy. So we know exactly what’s going around, and actually we can trace the type of different bags which are delivered into a single composting plant. We know if they are compostable, if they are shopping bags, and if they’ve been delivered by the municipality or not. So it’s a very robust monitoring and serving scheme that’s been running since 2004 or 2006.

Q: And for composters who want to understand the possible operational costs of accepting compostable plastics: in general, do composting sites need to alter their process or management practices in order to accommodate these plastics in any drastic way?

MR: If we’re talking about bags – no. If we’re talking about more sophisticated compostable plastic items like rigid packaging, it might be necessary to shred beforehand. Again, here it depends very much on what kind of composting plant we’re dealing with. Many composting sites in Italy which accept food waste on one line and garden waste on the other one, do not shred the food waste; they just mix it up with the garden waste.

If we move to the UK or other experiences where there is a mixed collection of food and garden waste, this material i normally shredded as a standard procedure. So the bags are opened and also rigid packaging is likely to be shredded already. So this answer is very plant-specific. Obviously keep in mind that, at least in our experience, composting plants have been designed to treat biowaste, so everything that is different – like packaging – the plant must adapt to this condition.

Q: Hilary, perhaps you have something to add here, because I’m sure in the US you’ve had more experience with rigid plastics like service wear and so on?

HN: We do have some experience with that, because I think we mentioned earlier that there’s fewer compostable plastic shopping bags, but also, to Marco’s point, it’s a very regional or composter based decision. There are a couple situations I can point out: for example, one of the composters I work with is accepting mixed solid waste. They sort a preliminary on the front-end for some recyclable and hazardous material, and then compost the process for twelve to fourteen weeks, and sort on the back-end. They remove any residuals and landfill it, and then sort to produce a compost product. That means they’re not concerned about separating rigid compostable plastics from non-rigid compostable plastics, because they’re composting everything –

MR: Sorry Hilary, but in that case, if I understood correctly, we’re talking about accepting mixed municipal solid waste, and at least in Europe this wouldn’t be allowed to be called compost when it comes out, since we need to produce compost starting from source-separated organics – separated at source at the household or restaurant, at the canteen…

HN: Right. So then another example of compost facilities that are accepting source-separated organics – and some other compostable plastics that meet BPI standards and are labelled for compostability – they are most able to identify compostable plastic bags that are green and labelled with BPI, and also some of the PLA cups with the green stripe, per the USCC labelling guidelines. The rigid plastics are sometimes harder to label or code, so they will often do their best to sort those out in the field when they accept them, and then at the end they screen them, and some of the overs are often reintroduced – as Marco mentioned there’s a similar process in Italy and the rest of Europe.

Some facilities have too much on an issue with contamination, so that the conventional plastics will remain in the overs, in which case they’ll have to landfill that material and the compostable plastics that might remaining – especially the rigids and cutlery and things like that. Those won’t be given the chance to further decompose. So that’s one of the opportunities further with the labelling and getting control over the marketplace for these products so that they can be more consistently composted and identified at the composting facility.

 

A VISION For the FUTURE

 

Q: Finally: is there anything you would like to see change or to see happen with compostable plastics or how they’re regulated? Any pressing issues that have your attention?

MR: I personally would like to ban the use of the word biodegradable for the kinds of items that are not compostable. We probably need a clear definition, at least continent-wide (world-wide would be too much). But it’s the question where we started from: what does biodegradable mean? So it sometimes creates so much green-washing that the composting sector – which is the backbone of the recycling scheme in many countries, since it represents the largest amount of municipal solid waste. So somehow there must be more stringent requests on what items can all themselves biodegradable. Otherwise confusion will still be quite strong for consumers.

HN: I would say “Amen” and that even in California where we have those labelling standards, it’s very difficult to enforce. So we need more capacity on a national level, which I think is more appropriate, rather than state-wide, to educate consumers around the difference between biodegradable and compostable, and enforce legislation to basically level the marketplace and make it possible for compostable plastics to be given the same opportunity and so that some of the green-washing can’t further contaminate our composting process and confuse people.

Winning Hearts And Minds: Outreach Strategies for Curbside Organics Collection: NYC Case Study

TOS_23_Outreach_Strategy_DSNY_NYC

This episode corresponds to Lesson 3 and Lesson 4 of our online course.

We join Director of Recycling Bridget Anderson to discuss the DSNY’s extensive outreach and education strategy for their curbside organics collection pilot program in New York City. We explore how they dealt with the different demographics in the city, how they used online social media and traditional media, the importance of face-to-face communication, the reasons why people don’t participate, and much more.

Thanks to If You Care for making this episode possible.

If You Care Certified Compostable Bags are made from potato starch from starch potatoes, blended with a fully compostable polymer, and are polyethylene and plasticizer free. Their potatoes are grown for starch only unlike corn which is grown for food. Their potatoes require forty percent less land than corn and no irrigation. For more, visit their website.

TRANSCRIPT

 

Breaking down the OUTREACH STRATEGY

 

Q: You touched on some of your strategies in the last episode, but I’d like to really understand the whole process. Can you tell me how the DSNY went about planning and implementing these strategies?

BA: Entering into a pilot program for New York City is a big challenge, because you have so many different types of communities and people with so many different experiences living in different types of housing structures. So we really approached this pilot from the perspective of what’s been successful in other cities? Most other cities have lower housing density – in New York City sixty percent of our population live in high-rise apartment buildings.

So we started focusing on the lower density areas of the city. In those low density areas, we reached out to the elected officials and the local community organisations to get feedback. Part of the strategy was to look within at sanitation and our sanitation workers know best what is happening on the ground – what neighbourhoods tend to be good recyclers already, and what neighbourhoods they think would be more amenable to doing a pilot program. Based on that, we chose a few committees; we reached out to elected officials; we talked to the local community organisations; and we tried to identify those “informal mayors” of neighbourhoods that might have their finger on the pulse of the community, to get feedback on if they think it would be successful in that neighbourhood and where the challenges might be.

Based on all of this information, we finalised our initial list of pilot areas, and then we sent a mailer to the households in the neighbourhoods about a month before the program was to start. Then we followed that up with a door-to-door door hanger that explained the program and that in a week they were to receive a brown organics bin, a kitchen container and information about the program. And then, when we do the bin deliveries – the organics bin, kitchen container and information packet – we have outreach people there during bin deliveries to talk to people on the ground; if somebody comes out and they have a question, we answer it. During those periods, we’ve encountered people who are just so excited about the program, and we’ve also encountered people who say “this really isn’t for me”. So we really try to change hearts and minds, and having people on the ground, and face-to-face communication, has been critical to getting people to even try the program.

We say that it’s a voluntary program, that you won’t get fined for not participating, but we encourage you to participate, and this is why: your going to help reduce the materials that we send to landfills that potentially could save taxpayer money, you could reduce incidences of rodents in the neighbourhood; it creates a cleaner waste stream for you, because you’re separating out the stinky stuff from the rest of your garbage. So, that on the ground, face-to-face, has been critical. It’s resource intensive, but it really has been extremely helpful to get the program off the ground in the beginning.

We also try to get articles in local newspapers – like the Daily News, New York Post, New York Times, if they’re interested – and then we have the local neighbourhood newspapers, and those have also been really helpful to explain that the scheme is coming to this neighbourhood, and that this is what it looks like, this is where you go for questions, this is our website… So they’ve been really helpful to get the message out.

Q: This strategy mirrors the strategy we lay out in Lesson 4 of our online course when we speak about outreach – that you need to let them know about the program initially around a month beforehand, and then have people going door-to-door to answer questions when the bins are delivered. And that’s exactly what you did, so it’s a very extensive campaign.

BA: Yeah, we’ve built email lists and newsletters, and any opportunity we can find the get the information to the local community, we use it.

 

 

Compost COMMUNICATION for different DEMOGRAPHICS

 

Q: Since there are so many different demographics in New York City, did you have different approaches that you used for the different groups of people?

BA: We had our standard approach, but in certain neighbourhoods, we had people on the ground who spoke the language. We had a Spanish speaker, a Chinese speaker, we also had a few neighbourhoods where Russian was an important language. So we had people on the ground so they’d have that specific face-to-face opportunity to speak with somebody in their own language. We also translated some of our materials – the most critical pieces of information – into multiple languages, and you can translate our website, so that’ been very useful as well.

One thing we have discovered is that, especially if you’re in an area that has a lot of retired people, we can’t rely on the web or social media as our only information portal. So, we have a hotline and utilise the city’s 311 program, and we have a lot of soft responses to the most common questions that we get. So we’re able to utilise phone calls as well as an opportunity.

 

 

Getting RESIDENTS started and using COMPOSTABLE plastic bags

 

Q: What were the most common questions that you got, or the most common issues that people had?

BA: We get a lot of questions like “is this mandatory, do I have to do it?” Because I think some people get the mailer and, even though it says it’s a voluntary program, they assume that because it’s a notification from the Sanitation Department, they have to participate. We encourage people by saying “it’s not mandatory, but we encourage you to try, because this is a new strategy and we’re trying to see if we can make it work in New York City”. One of the strategies that we’ve recommended to people that using certified compostable bags is one way to collect the material inside your home and get it out to the brown bin in a way that’s more similar to maybe what you used to do if you used plastic bags for garbage.

The availability of those compostable bags has been a problem. It’s taken us a while to get the bags into retail stores – there are also online outlets for the bags. The price of the bags has been a problem; some people say the bags are to expensive and they won’t use them, or that they would participate in the program if they could use the bags, but the bags are too expensive – that’s an example of something that’s been a challenge. We do say that you don’t have to use compostable bags: you can use paper bags, and you don’t even have to line your kitchen container at all if you don’t want to, it just means you have to rinse it out. And with the brown bin, you don’t have to line the bin if you have a way to rinse it out, or you can use paper bags or certified compostable bags. And this spring we’ve added that people can line their brown bin with a clear recycling bag. It’s not our preference to do this, but to encourage participation and because the compostable bags are not yet available everywhere, we are allowing people to do this to get people used to the program.

Our hope is that eventually the compostable bags will maybe become cheaper and be more available, and then we can switch out the regular plastic bags. One of the challenges with the plastic is that it doesn’t break down in the composting facility, so it adds to the contamination rate, but at this point we do think that it does encourage more participation because it’s more similar to our other recycling programs. In our recycling programs, you can use clear plastic bags, or you can put things directly in the bin, so it’s more parallel right now to those programs.

Q: So you’re thinking is that it’s more important to just get them on board and into the habit and then it’s easier to change…

BA: Right. There’s the challenge of the front end, which is participation, and then there’s the back end, which is trying to do something useful with the material. And we’re trying to balance those two things right now.

 

 

The most IMPORTANT aspects of an OUTREACH STRATEGY

 

Q: And in terms of strategy, would say that the face-to-face communication is the most important aspect?

BA: I don’t know if it’s the most important, but it’s a critical piece. I think getting articles in the media and generating a buzz…and we’ve been very lucky where the local television news media has picked up the program, the local neighbourhood newspapers have picked up the program; the city-wide newspapers have picked up the program and we’ve had radio shows pick up the program too. Having people hear repeatedly about the program has been absolutely critical.

Then, once an area becomes a pilot area where people are receiving the program itself, the on the ground outreach has been extremely useful. Not everybody reads the mailers: if you receive a mailing from the city, it might end up directly in your recycling bin – hopefully your recycling bin! And so, having people out there on the ground during bin deliveries to really make sure people understand the program is important. The elected officials and community boards have also often hosted meetings where people can come and ask questions.

I think what’s critical is that you try to hit every outreach opportunity that you can, because you never know who might be listening in which venue. And the bigger the program goes, the more difficult it will be, because of the more neighbourhoods we’ll have, and we’ll have to be really efficient in how we implement the process, because we won’t necessarily have an army to be in every neighbourhood all the time.

Q: And since you are planning to expand, is there anything you’re gearing up for, or planning, in terms of outreach campaigns for when the program does go city-wide?

BA: So this year, we’re working through the analysis to figure out if we are able to expand this program, and really think about it as a program that we’re going to expand city-wide – we’re working on this right now. So, we have plans to further expand in the spring to another, approximately, forty-thousand households. And this fall, we’re aggressively trying to recruit more multi-unit buildings to really understand the challenges to making this work in multi-unit buildings.

Then, next summer of 2015, we will start writing up our analysis and provide the city-wide expansion plan. In the end, when we expanded recycling, we started recycling in portions of the city and then expanded city-wide, we took a geographic strategy, where we said “now we know we’re going to go city-wide, let’s phase in each area of the city”. It is likely that that would be a useful tactic also for this type of a program once we expand it city-wide. But we haven’t yet crunched all the numbers to understand exactly how quickly it would happen and who would start first – those types of things.

 

 

The TROUBLE with high-rises

 

Q: Since you brought up high rises, I want to ask, what was your experience in dealing with the building owners and supers – were they on board right away, or was it hard to convince them to change?

BA: We’ve been lucky at this point because we’re recruiting buildings, and they are voluntarily saying to us that they would like to join this program. I would say one of the most interesting things to date is that it’s the co-ops and the condos – the buildings where people own their units – that tend to be much more interested in the program than the building management companies for rental buildings.

Where you have a co-op board, the co-op board president is perhaps the champion of the program, they’ve really been successful in getting buildings on board and participating, and committing to manage the program in their building. Where we have a resident of a rental building contact us, we then contact the building management company, and more often than not, the building management company says “I know this resident is interested in the program, but I don’t think I have the resources to manage it”. So we’re really working this fall to see if we can get more rental buildings on board to understand what the constraints are for a rental building as opposed to an owner building.

 

 

Residents reaction to the collection program

 

Q: In general now, how has the reaction been from the participants of the scheme so far, has it been mostly positive, or have there been any comments on it?

BA: It’s mixed. I would say you have the core group of residents that are really into the program; they’ve jumped on board and have given us feedback like, “I have no trash left!” and things like that. You do have, I would say, a significant set of residents who’ve chosen not to participate, and that’s the group that we’re really trying to recruit now. So we’re going back into the pilot areas and saying “you know, this really is beneficial and will make your trash management cleaner”, and things like that.

But we really have a mix. The people who participate are gung-ho about participating and enthusiastic, and then you have folks who are really choosing not to. It’s interesting when you look at the numbers; we have RFID tags attached to the brown bins, so when we go and collect, we’re able to see how many bins are placed out on each collection route and are able to get a sense of participation, which is really helpful for the pilot program. And what we’re finding is that there are some people who started in the program, and then they dropped out, or they dropped out in the winter and they came back again in the spring – and so you can see patterns there.

You also see, surprisingly, bins that had never been placed out for collection for three or four months, and then all of a sudden you see them being placed out for collection. So maybe that’s somebody who really wasn’t interested in the program and then saw their neighbours do it long enough that they said, “maybe I’ll five this a try”, or maybe they have a lot of yard waste and thought, “maybe I’ll use this for yard waste”.

So we’re trying to understand the patterns of behaviour. How do people behave with the program? Is there consistency with participation? It’s a pretty interesting analysis to understand people’s behaviour. And it’s a different thing from recycling – recycling is dry goods, so that “ick” factor doesn’t exist, whereas with organics it’s a little bit different. Yard waste is less scary than the food waste portion of course. But we have really great testimonials of people who say, “I really don’t have much garbage left, once I recycle and do the organics”.

Q: I often wonder about the people who start and drop out – what their reasons where. And it’s probably more difficult to get them back into the program again after that too.

BA: Yeah. And our feedback is that some people say “I had a free sample of compostable bags, and once those bags ran out, I tried to buy them and I couldn’t find them”, or, “they were too expensive.” So for those people, we tell them that they don’t have to use those bags, and list the other strategies we encourage them to try. There are some people then – it was a particularly tough winter last winter – and they said, “you know, I just didn’t want to do the program over the winter, but now that spring has arrived, I’m coming back.” It really is varying reasons.

 

Wise words of advice.

 

Q: And finally, do you have any advice on planning and implementing an outreach program, for those listening in who might be starting their own? Any pitfalls you want to warn against, or tips to share?

BA: If you have ideas of which communities you think you would like to start the program in, I would recommend having conversations with those local communities pretty early on. Give yourself at least a few months before the program starts to really start talking to that community, explain the “why” of the program: why are we doing this, and explaining how it would work. The more they feel a part of the development of the process, the better the response. I the very pilot area, we had a situation where certain people were told that this was going to be the pilot area before they were notified on a local level, and they felt a little bit slighted. So it was important for us, moving forward, to really get into those local communities. These are our candidate pilot areas: let’s get in there and talk to them and make sure they understand the program that’s coming. And then, when it comes, they’re not surprised. So having that up-front communication before the program starts would be an important piece.

I also think providing the tools – providing the bins and the kitchen containers – has been helpful. Giving them the tools so they didn’t have to go buy things right away was really helpful. In the initial pilot areas we had sample supplies of compostable bags so they could at least get themselves started, and that was also helpful.

TRANSCRIPT

The Story So Far

 

Q: Can you tell me how the program got started?

BA: Organics collection was a pilot that actually started in the schools, in the 2012-2013 school year. We started on a select number of schools and focused on school cafeterias and school kitchens; and it was really an effort that was spearheaded by a number of parent-teacher organisations. They did a great job and Sanitation saw what they did and decided that we would try in on a slightly larger scale.

Then there was momentum to try this in residences also – in homes. And we’re in all five boroughs: we have pilot areas in the Bronx, in Queens, Brooklyn and Staten Island – and then in Manhattan, which is a very dense area with lots of high-rise apartment buildings, we actually have selected apartment buildings that have volunteered to participate in the program. One of the challenges is to figure out how to do this in high rise buildings.

Q: How does the pilot program operate today? It is a voluntary program at the moment, correct?

BA: Yes, the pilot is voluntary. We chose the pilot areas in a combination of where, collection-wise, we thought it would work well operationally, and where there was interest among residents and among elected officials. We also looked for those low-density areas. So, it was voluntary and not everybody in the pilot areas chooses to participate, but everyone is given the opportunity.

We deliver a brown bin, which is what you set out curbside, and then in addition we deliver a kitchen container for each household, so that you have something you can use in the kitchen to collect the material. And then we provide a lot of education and outreach, and brochures…

What we do is we send a mailer to everyone in the pilot area, saying “this program is coming, this is what it is and you can expect to receive your brown bin”. Then about a week before the brown bin arrives, we do a door hanger. We go door-to-door and hang a door hanger and say “Your brown bag is arriving this week. As a reminder this is the program, it’s voluntary, we hope you participate, and this is how it works”. And then when the brown bin arrives, in that brown bin is the kitchen container and the brochure that gives details about what can and can’t be put in the bin – best practices for how to manage the material.

Q: I also saw just the other day that the Mayor of New York and his family made an ad using the brown bin…

BA: Yeah, it’s interesting, they approached us. One of the pilot areas is where the mayor’s home is – this is the mayor’s home before he moved to Gracie Mansion, which is the official Mayor home. He actually approached Sanitation and said “I would love to do a video. My daughter Chiara is very interested in this program”. And so, we developed a script for them, which they took and then tweaked, and they created the video. And the video turned out beautifully – I thought it was a great video. And now they’ve moved to Gracie Mansion, and we had the organics collection program in Gracie Mansion with Mayor Bloomberg, and now we’re continuing it with Mayor de Blasio, so we’re very excited about that.

 

 

LOGISTICS of COLLECTING organic waste in New York City

 

Q: I want to ask you about the expansion on the program to high-rise buildings, because as you said earlier they can be quite a challenge. How did the DSNY decide to deal with all the different types of buildings?

BA: There are other cities in the United States that already do this organics collection program – cities like Seattle, San Francisco, and Toronto in Canada – and we looked at what they were doing, where they found success. Most of those cities are lower density and don’t have as many high-rise buildings. Toronto is maybe the closest to New York City in comparison to a place that already does organics collection. And we thought, let’s try this program in the lower density areas of the city – because that’s where there’s been a precedence set to have a successful program in other cities. So, we looked for parts of the city where we would focus on single family homes and small apartment buildings that are up to nine units – little town houses, brownstones, and then small apartment buildings. The pilot areas are primarily that size of building.

Then we said, if we’re going to make this a viable program, we have to tackle high-rise apartment buildings, because a significant portion of New York City’s recycling, you have to come up with an internal recycling program that then allows the building to manage the waste and get it out on the curb for Sanitation to collect. We have to do the same thing for organic material. So, we actually work with the building management and the co-op board, if it’s a co-op building, and come up with a system for how they’ll manage the organic waste inside the building to then get it out on the curb for us to collect

Q: And how many high-rises are you working with at the moment?

BA: We have over a hundred high-rises at this point.

Q: That’s quite a few. And what has been the DSNY’s strategy in dealing with the various building types? Do you have separate systems, depending on the high rise, or is there a single system that works across the board?

BA: I would say we service a different range of types of buildings – we have old, old buildings, we have brand new Leed certified buildings…a lot of it depends on the infrastructure of the building, where there’s space to put the bins. It’s very similar to recycling – where is there space to place the bins, either on each floor or in some sort of centralised area, where people can then bring their material to drop it off. And then the building staff brings it out to the curb.

So we have a few different strategies that are the most common. One is, if our large buildings tend to have chute where people will take their trash, and it foes down to the basement. In a lot of buildings there’s a little chute room where the chute exists. And if there’s space on each floor, and the building management are willing to provide the service, we recommend that both the recycling and the organics containers are put in those shoot rooms on every floor. It’s the most convenient for the residents.

That doesn’t exist in all buildings, so what’s also quite common is a centrallsed location on the first floor, possibly the basement or in the area nearby where there’s parking, where the recycling and organics bins are placed. And that’s more of a centralised area. It’s less work for the Super to service, because it’s only location – but it’s potentially a little bit less convenient for the residents because they have to go downstairs. We find with both recycling and organics collection, convenience begets participation. So if it’s easy and convenient, people will participate. The people who want to do it are going to do it no matter where you place your collection location; the people who are saying “well I’ll do it if it’s convenient.” If it’s easy for me to just throw it down the chute on my floor that to bring the organic material or recycling downstairs, then you may lose a few people in participation.

So, we have a lot of signage – signage is absolutely key to let people know on every floor where the collection location is in the building. And keeping the collection well lit, safe, secure is also key to having people comfortable with using those locations in the building.

Q: Another crucial part in organics collection programs is the collection times. How did you decide on collection times and are they different from place to place?

BA: We have a few different strategies. About fifty-thousand of the households are being offered twice a week collection, and that’s the same frequency as refuse collection. The idea is you just set out your material on collection day, but you separate the organic material from the waste and recycling. In the other half of the homes, we’re testing once a week collection. Basically, the way things work is that here you have twice a week collection of trash, once a week collection of recycling in most parts of the city, and so we’re either offering twice a week collection on the same frequency as trash collection, and the other half od the pilot, we’re offering once a week collection on recycling day. So, it’s essentially just another recycling stream to set out on your recycling day.

Q: Do you know which one is more successful, or which you’re going to pick in the long-run?

BA: We have one area of Brooklyn, where we started them in the Fall with once a week collection and switched them to twice a week collection in May, so we’re going to be studying that one. We don’t have any results yet, but we’re hopeful that that little neighbourhood – it’s called Windsor Terrace – will actually help inform us what the effect is of twice a week versus once a week.

Q: Was it difficult, in a city the size of New York, to plan collection routes and to cooperate with the haulers?

BA: So in New York City, the city actually has a municipal hauling workforce and we collect material from residences, agencies and institutions. And so, it was simply a matter of making the case to add some to add trucks in the budget to service the same routes. And we chose the pilot areas so they were co-terminus: they were the same areas as the regular routes, so there was no issue there. People were very positive about piloting the program.

Q: The ultimate goal is to make this a mandatory, city-wise curbside composting program. How are you planning to get there?

BA: The city council passed a law for us to conduct this pilot program, and the our mandate is a two-year program. And in the October of 2015, we will have to present a report to city council and say, this is how the pilot went, these are our recommendations moving forward. And so far we feel pretty positive about the participation, about people’s understanding of the program. We’re working right now to evaluate the pilot to understand what the best practices, what are the best collection frequency, what are the other aspects of the program that we’d want to take and scale up.

Scaling up city-wide is going to take quite a while. It’s not going to happen overnight; it will have to be a phase-in process. And part of it too is that what happens is if you separate the organic material and recycling fully, you don’t have as much refuse left. So, one of the big pieces is understanding how we reconfigure our routine and our truck routes so that we manage the material differently. So, maybe we don’t need as many refuse routes because there’s not as much refuse being set out as we add the organics routes.

So there’s a lot of operation pieces that we have to put into play. There’s also the aspect of geography – do we roll out district by district, which is maybe what happens. So, we’re basically in the planning process right now as we roll out the pilot, to figure out how we would do this city-wise, and I would say that it’s going to take ten years to probably get to the entire city.

Q: We tackle this whole aspect of organics collection programs in Lesson 4 of our online course on Compostory.org, so those of you listening, can go straight to the course on our site and take a deeper look at.

 

 

COMMUNITY COMPOSTING – A Critical Piece to the Puzzle

 

And now, I’d like to touch on the topic of community composting, because in our last episode, we were taking a look at the community composting movement in New York and we know that the DSNY has been quite involved in supporting this as well. Can you tell me a little about how you work with community composters in the city?

BA: Yes, we have a longstanding relationship – over twenty years – working with community composters. The New York City Compost Project is a group that we run and fund, and we have non-profit partners throughout the city where we provide education services – helping people to understand how to compost in your backyard, if you want to take your yard waste or your food scraps and do it yourself. We work with community gardens, and we provide finished compost from the material that they city collects and manages, and we provide tools and equipment, and technical advice for how to set up composting in community gardens.

We also work to provide drop-off programs. We have food scrap drop off programs throughout the city – we’ve about seventy in operation right now. And those drop-off programs are critical, because they get people in the mindset of “oh! this is what this is…I take my food scraps and I can bring them somewhere else and recycle it – have it be composted.” So, we see the community composters as absolutely critical to helping people understand the concepts of organic separation, what happens to it, what are the benefits to it – it’s an absolutely critical piece to the puzzle.

Q: So you agree with David Buckle, who we interviewed last week, that community composting is an essential part of creating a successful organics recycling system?

BA: Both programs are very important, yes.

Q: When speaking to David, it was clear that he had concerns about a lack of vision from policy makers in the city, that might not understand the importance of local collection and composting and wouldn’t necessarily prioritize community composting over other collection systems. What’s your take on this statement – have you seen this yourself?

BA: I actually have not seen that. We’re trying to position the city, in terms of organics waste collection, to fulfill a number of goals, and community composting plays an extremely important role in terms of introducing the community to organics and composting and the concept that you can recycle this other part of the waste stream, and to showing what actually happens to your organic waste, how it turns into compost; and creating a valuable product for the local communities.

The capacity for local, small-scale community composting is too small to handle the vast hundred and thousands of tons of material that we’re looking to divert through organics recycling. So, we as a city also have a parallel mission to find how we bring composting to scale and actually move major tonnage of material to recycling, to composting and to renewable energy. So, for us we see both as extremely important, because the local community composting creates beneficial use for the city. They have been critical to introduce the concept that this is a useful strategy but it’s not going to help us divert all of the waste. There’s so much waste in New York City, that we don’t think we’d be able to handle it through community composting. You have to have large, permitted facilities to really handle that quantity of material.

But there’s plenty of material to go around, and absolutely – this is why we fund local community composting operations – we see it as a critical piece to the pie, a piece to the puzzle.

We’re really focusing on [understanding] how we create this as a cooperative program. But it’s really tough, I mean, you have people who’ve been in the trenches for two decades working on local community composting, and I understand that maybe there’s a fear that if the city takes over this program that there won’t be a place for local community composting, and we do not at all see that as the case. They are both critical to achieving the city’s overall goal, which is diverting major tonnage of material, and creating beneficial use for local communities.

 

 

Compost Use & Compost Markets

 

Q: If the program is rolled out city-wide, you will have a lot of compost on your hands. What are you planning to do with the compost and what are you currently doing with it?

BA: We take the material from the pilot to local and regional compost facilities. With the material that’s taken to the regional facilities, we don’t actually take back the compost at this point. There may be a situation moving forward where we develop a relationship where we would have a certain percentage of the compost come back. With the material that’s processed locally, we turn it into compost and use it in street trees, we use it in parks, we use it in gardens. We have give-back programs for non-profits, schools and community groups, to use the compost for their greening projects. We also create a mulch product in addition to compost. And most of the material that we’re currently compost locally is yard waste, and that creates a beautiful mulch product as well as the compost. We also sell the compost to landscapers, so we do have a small revenue stream there.

Q: Are you involved in creating markets for compost, or encouraging market growth for compost?

BA: For the material we compost locally, we’ve worked on this landscaper market, and it’s really a bulk purchase type of situation. We have not gotten into the business of creating a retail market for the material – it just hasn’t been necessary to date, because we’re handling and selling all the material with the landscapers and with our give-back programs. With the regional composting facilities that are taking the material during the pilot period, we have not been involved in how they’re marketing the material, although we are evaluating with them the quality of the material we’re giving them, and the quality of the material that comes out, so we understand better what it is we can create from the material that would come out of a New York City stream.

Q: What is the quality like, and what contamination rate are you experiencing?

BA: The quality is quite good. In the residential program, our contamination rate is very, very low. It’s well below five percent. So we feel very good about that. It is a voluntary program, so the people who participate want to participate and try to do it right. That may change obviously when you make it mandatory.

Q: Is creating a market for compost something you’re looking at doing in the future?

BA: It would definitely be part of our larger plan. We want to ensure that the material is going to beneficial use – and is not just composting; we’re also looking into anaerobic digestion so we can create energy from the material. But creating a viable program, if there’s a way to generate revenue from it, that’s obviously a huge benefit, so it’s definitely something we’ll be looking into.

Q: Yes indeed, and we just released a new lesson – Lesson 5 – of our course were we take a detailed look at market creation for compost as well. And in terms of your aims or objectives with the organic material – as you said, diverting materials from landfill and supporting communities are on your list. But what about the organic material itself and what it’s used for? Are you focused solely on creating revenue streams, with waste-to-energy for example, or are you more concerned with creating quality compost to help replenish the soil?

BA: One of our biggest objectives is to find ways to reduce the material going to landfill, and the parallel objective is to create beneficial use. And obviously as a city we are concerned about being cost-effective in what we do, so any opportunities we have to market material and gain revenue streams is important. We are focused primarily at this point on the composting, because that’s a proven technology; we know there are existing facilities, we know that a useful product can be created and marketed.

Anaerobic digestion is a little bit newer of a technology for us in the North-East. There are wastewater treatment plants that have been using anaerobic digestion for a long time, and the question is: how viable is it to utilise AD for a municipal organics program? What we’ve learned is that the challenges are when you co-mingle food waste and yard waste, and food soiled paper, that can cause problems with anaerobic digestion, and so we’re trying to figure out if those energy conversion technologies (such as anaerobic digestion), could be viable with our waste stream. We won’t be able to collect yard waste separately from food waste, we really need the efficiency of collection to collect it all together , and so the question is: is there an option to utilise anaerobic digestion with that type of material streams.

On the commercial side, with businesses, we expect it’ll be food waste. So we think that there’s quite a good opportunity there for turning food into renewable energy through anaerobic digestion. But on the residential side, we think it may be more difficult.

Q: So you’re going to stick with composting, which is probably the most ideal option on many fronts.

BA: Yes. The challenges there of course is that you need a lot of space for composting – there are siting issues. For New York City, siting any new facility is expensive and difficult. There’s permitting processes, and because we’re right the confluence of three different states, each state has their own permitting requirements and procedures.

 

 

Closing the Loop

 

Q: And for our listeners who are rolling out similar programs, we strongly recommend fully integrating the multiple benefits of compost use in the program vision. Keeping organics out of a landfill and managing the waste streams is important – and it’s usually the main argument to be had in large cities – but then programs need to take into account all the benefits of compost use as well when developing operations. We’re finding out that many programs need to put more focus on end-product quality. So there’s a whole ecosystem involved here and it goes beyond just the ‘waste management’ side of things, so it’s very important to include that in the program vision.

And so Bridget, in terms of closing the loop as much as possible do you travel far to the composting sites you use, or?

BA: We have one composting facility on Staten Island, and that’s a great system. So, all the material that we collect on Staten Island, stays on Staten Island, so that’s a very closed-loop and successful system. For the other material that we have, everything is within a hundred miles of the city, but we do have to truck it outside the city. And so, we basically say it’s regional capacity. And we’re hopeful that once we position ourselves to go to scale, that we will be able to work with companies who will local themselves closer to New York City.

 

 

Organic Waste COLLECTION in A MEGACITY: Successes and Advice

 

Q: The project has been a great success so far and it’ll be exciting to see how it progresses, but already you’ve gained a lot of experience and tackled a host of issues. I’d love to know more about the pitfalls and successes you’ve experienced on your journey so far. How has it been?

BA: Yeah, so one of the best things that has happened is that we found these local resident champions of the program, and they are the best sales people. Having peer-to-peer interactions where people are explaining to their neighbours how great the program is, how little trash they have left, and how easy it is, has been incredibly helpful. And we found that it takes a lot of work, but the in-person interactions that we have as a program with the residents is really the most effective way to get people who may be a little bit shy, nervous or intimidated on board.

We get a lot of questions and concerns about rodents and pests, and they say it’ll be more work. Well, we say it’s the same amount of waste that you’re throwing out now, you’re just putting it in a separate bin. And the bin that we have has a lid and a latch, and so we’re able to explain to people that it actually reduces the potential for pest issues because you’re containing that waste. Right now New York City has primarily a bag program, so material is placed out at the curb in bags, and when you have a plastic bag, it’s much easier for a rat to chomp into the back and access the food. If the food is in a container, it’s much more difficult for them to access that meal. So we’re working with the Department of Health to study how the rodent populations are affected by the program.

We’ve also had some people say there’s been fruit flies and maggots, and those sorts of things. And it’s amazing because we use social media a lot in the program, and we often have residents providing best practices and tips to the people who have concerns about fruit flies and maggots before we even get to them. So, we have a list of best practices and tips, but we really do rely also on that peer-to-peer education.

Q: And finally, for our audience who might be wondering how to start a similar program in other large cities around the world, what advice would you give for rolling out a system like this in a large city?

BA: I would say that you need to have a plan for where you’re going to take the material. Don’t set up the front-end without the back-end in place – that’s critical. I would say the best way to roll-out the program is to do it so it follows the existing collection schedules and the existing behaviour patterns of people – so we said “add this to the recycling bay, they’re already setting out recycling” or “have them set it out on the same days as trash”. That way the behaviour is sort of the same, it’s just that you’re separating out the material.

The stakeholder engagement has been critical, so speaking with the elected officials and getting them on board – they can be your best advocates in their districts. We found that not only the elected officials, but the local civic organisations have been critical. You have these informal mayors of neighbourhoods that really understand the neighbourhood and understand what messaging will work in that neighbourhood; is this a neighbourhood that will respond better to the fact that we’re trying to save taxpayer money? Is this a neighbourhood that will respond better to the environmental message? That’s been critical for us to target our education and our messaging.

TRANSCRIPT

Where COMMUNITY COMPOSTING is today

 

Q: The community composting movement is growing strong in New York at the moment. The DSNY, for example, who started their NYC Compost Project in 1993 to support local composting programs, now support over 200 composting sites and 8 to 10 mid-size operations in the five boroughs, and the collection points for dropping off food scraps at greenmarkets are growing in number: over half of the greenmarket farmer’s markets are outfitted with a drop-off program.

As a long-time community composter currently working at Added Value Redhook Community Farm in Brooklyn, you’re right there on the ground watching all this happening. Can you give me a brief picture of what community composting looks like today?

DB: Quite a bit of it depends upon how you define community composting. There’s an awful lot of things going on in terms of community composting in the city; there’s quite a bit going on in terms of closing the loop, and a lot of that is in the community gardens around the city. Folks will bring their kitchen scraps to their community garden, where they get composted in small systems. What there’s less of is community composting that is defined not only as trying to close the loop as much as possible on organic material, but also engaging the public as much as possible, so that we can promote environmental stewardship.

Q: Community composting has had a long history in New York, hasn’t it?

DB: Community composting has been, to a degree, fairly strong in New York, because of the presence of community gardens around the city; New York City is unusual in having hundreds of community gardens. What’s new for community composting is adding in the public engagement, and trying to make sure that capacity grows more. The community gardens can take organic material to a degree, but at some point it’s just too much for them because their systems are usually quite small. So we’re trying to develop more sites that have bigger capacity and can take more organics.

 

 

New York Policy Makers Lack Strong VISION For COMMUNITY COMPOSTING

 

Q: In terms of a vision for community composting, many (including yourself) are in favour of small-scale, decentralised models that prioritise closing the loop, can you tell me what policy makers have in mind for community composting in the city?

DB: We haven’t yet seen a strong vision articulated by policy makers for the future of community composting. What I have experienced is more helping what already is happening. So, assistance for community gardens and things like that. The Department of Sanitation has been very helpful in terms of developing slightly larger sites that can take more material, but I haven’t seen a vision that essentially articulates where we want to be in the future twenty years from now.

Q: Why do you think that is? We know how challenging it is for them to coordinate all of the different aspects in such a large city, as well as rolling out such a large collection program.

DB: Perhaps they haven’t been challenged enough to realise that this is the sort of thing we will have to confront sooner or later, because, to me, there’s no way to get around the future in terms of closing the loop on the travel of organics. We will, sooner or later, have to find ways to make sure organics are not travelling large distances in order to be processed. We think that’s the kind of vision that has to be articulated at the policy level. And then, everything else comes along with it: even if we optimise community based composting as much as we can, because our cities in the US are so badly designed, there’s no question that we will also need curbside pickup as a municipal function; we’ll also need commercial composting. We’ll need all of those things.

What we’re not seeing is a vision that’s big enough and future-thinking enough to say that we have to optimise community based composting first and foremost, and then pull in all these other elements to best address the organics.

 

 

Community Composting In Practice

 

Q: Before we tackle the bigger issues, can you tell us more about how things work today with community composting: how are the organics are collected & processed?

DB: One of the most exciting things going on in New York City in terms of organics being collected is the farmer’s market collection program. It’s run by a group called Grow NYC, which has several green farmer’s markets around the city, and they have tables where folks can bring their food scraps from home, drop off their food scraps and then buy their food to take home, where they will make food scraps that then go back to the farmer’s market the next week. So it’s a wonderful, local cycle for the organics stream.

The food scraps are distributed to different sites around the city, within the city limits, one of which is where I’ve spent a lot of my time called the Red Hook Community Farm in Brooklyn, New York. And so we will be getting that material from farmers markets in the borough of Brooklyn, closer by. We also maintain tumblers so that community residents who can’t compost at home can walk their food scraps over and put them in the tumblers, and that material will wind up in our larger system over time.

Q: Do you see a lot of people participating in this, or is it gaining in popularity?

DB: It’s growing more and more popular as people hear about it. They’ve just passed the three million pound mark in terms of the collections they have done, so it’s to be quite big of a scale, and they seem to be adding new farmer’s markets every year. So that’s very exciting. Another exciting development is that the Department of Sanitation has begun to support the development of urban farms, and you’ll see a very similar type of magic happening, because at the urban farms they will often have farm stands where they sell locally grown, fresh produce right next to the fields where the produce is grown. So folks, when they come, will bring their food scraps. And this is what happens in Red Hook, Brooklyn, because folks will come and bring their food scraps, drop them off in our tumblers, and then buy some produce at the farm stand and go back home and create a very nice local circle – a closed loop for the organics.

Q: And how is the organic material typically collected from the farmer’s markets and urban gardens?

DB: Well at Added Value’s Red Hook Community Farm, the material is brought to us. So, local residents will walk it or bicycle the material from their homes. And then we get some of the scraps from the Grow NYC farmer’s markets, which is brought to us in plastic bins by a truck. The big difference is that it’s just travelling within Brooklyn, as opposed to having trucks drive on highways and downs streets. We have a smaller truck, as opposed to the bigger trucks that get loaded up and then have to drive outside the city for a distance to transport the material.

Q: One issue we often talk about with organics collection is the contamination rate, and the quality of the organics collected in New York has been described as pristine. Would you agree with that description? What has been your experience?

DB: Well I can’t speak for the city, but what I see happening is that, in terms of the material collected at the farmer’s markets, we’ve very, very clean material that’s being dropped off – in particular because the folks who go to the trouble of collecting their food scraps and bring them to the community sites once a week are very conscientious, and so our level of contaminants are extremely low.

 

 

Curbside Organic COLLECTION And COMMUNITY COMPOSTING – Can They Work Together?

 

Q: With the DSNY managing an ever expanding residential curbside collection scheme for NYC, can community composting be an integral part of the system, or are they at odds with one another?

DB: In my view they are in direct conflict and at great odds in some ways, and it depends upon the vision that is articulated for policy in a city. For example, when I started this work, I talked to some folks in Toronto, who were very active in trying to promote sustainability in regard to how organics were treated in the city. And they had a choice – they had to either support community composting and invest in it as much as possible, or invest their time in trying to develop curbside pickup. They chose curbside pick up, because they felt it could be a bridge to community composting, and they told me that the exact opposite happened.

Because they had never developed a culture of people trying to keep their organics as local as possible, once the curbside started, it was very challenging to get to that culture, because people could just put things on the curb, and they got into the habit of that. So now what they’re looking at is a much longer time-frame for persuading the public that it would be better for their organics to stay much closer to home because it’s more environmentally sustainable.

So in that way, Toronto shows that curbside municipal pickup and community composting can be at odds and in conflict, if there’s no vision of policy that says we need to be developing community composting as much as we possibly can, while at the same time we recognise that not everything can come to community based composting sites – we do also need curbside municipal pickup. But you see, that kind of vision doesn’t see them at odds. That kind of vision says: let’s do what’s most environmentally first, and develop community composting as much as we can,  and then recognise we also have to do curbside municipal pickup, as well as commercial composting. That’s different from what happened in Toronto where it seems it was posed as a choice, one or the other, and now my colleagues up there are saying it will take them so much longer to ever develop community based composting.

Q: That is something to bear in mind when developing policy. Now let’s move on and talk about the benefits of community composting. I’m sure you agree with me in saying that community composting schemes can really make an impact in educating people on organics recycling and the importance of keeping the stream clean?

DB: That’s true. One benefit is that unlike glass or plastic, or metal, it’s much easier for the public to participate in the process when it comes to processing the organics. They can’t as likely do that with glass, metal or paper, but with community composting, they can go very close to their home, contribute to the compost process, and – if it’s a type of a site that places a value on community participation – volunteer in making the compost with their own hands.

That has several benefits. One is that if the material is used in their community, they get much more invested in it, because they see that it’s going to be used for a local urban farm, or for street trees, or a food garden their local public school where kids attend. So there’s a much stronger connection to it, and more dedication and commitment.

But they also just care more about it in general. So one effect, if it’s optimised, is that people will care more about what they’re putting out on the curb as well. So, they may take some to community sites, but if they’re putting some on the curb for pickup, they know the importance of not having contaminants if they’re participated at a community compost site, so they’ll be more careful that way.

Q: On the note of education – how do you draw people in and get them interested?

DB: I’ve never found it hard. On the site at Red Hook Community Farm, as long as you post hours that are consistent – we put hours up on our website so people can check to see when they can volunteer – and we get in touch with the different volunteer groups to let them know what the opportunity is. Very quickly things take off, and the question is not so much, “how do we get people here?, it’s more about “oh, is that too many people?”, or “how do we best manage this so everyone can have a meaningful experience, given how many people are here?”

Q: That’s a great problem to have.

DB: It is, it’s a wonderful problem. But it just further demonstrates the importance of community composting – that there’s a hunger on the part of so many to participate in this type of work.

 

 

Job Creation In Small-Scale COMPOSTING Projects

 

Q: For those out there that might not be convinced of the importance of community composting yet – can you tell us some more benefits you’ve seen?

DB: At the top of the list, it’s better for the environment. It reduces environmentally costly transport by so many trucks on the streets. It better supports local food growing, and it also supports other green projects in communities. So, if folks want to green up their community with more street trees or flower gardens, or food gardens, there’s more compost available locally to do that.

And then here in New York City, after the last hurricane we had, which was so devastating, by building up our urban soils and improving storm water management through community composting, we make ourselves more resilient in the face of climate change. The last hurricane, Hurricane Sandy that came through New York and so devastated us, made that all the more important.

And lastly, over time, if we can develop community composting sufficiently, according to the broad vision of what’s the most sustainable way to live, it will generate jobs. We’re not there yet, but we’re trying – I’m actually running a job training program out at the Red Hook Community Farm, and the movement has to get much bigger in order to start generating jobs.

Q: We’re very interested in creating self-sustaining models that benefit the economy and society as a whole – and this is an area that composting and recycling initiatives have a lot of potential. So apart from growing the community composting movement and the sites themselves, what are your main problems or focuses right now in creating jobs?

DB: One important development we need now – and we’re so ready for this – is the generation of revenue models. I can’t help but say that if community composting is going to be successful, we need some kind of funding stream. The ones that have been developed commercial enterprises don’t work, because the goals are a little different. But on the other hand, community composting can’t be just a none profit endeavour, because you would wind up chasing grants all the time.

And if one sign of success is that there are more composting sites, the problem you have is that the foundation pie (i.e. grants), gets smaller and smaller. So, much like with urban agriculture (at least in the US), the answer has to be to get a little more business-like and pay more attention to generating revenue, so that even when we continue to turn to foundations for grants, we also have some generation of revenue to develop financially sustainable models of operation.

Q: In relation to this, what is the market like for compost at the moment in New York – is it strong?

DB: It is. Before the hurricane we were able to meet the farm’s needs and start to explore some markets, and we found that many buyers are willing to pay a premium – to pay more than they otherwise would because they knew it was locally made compost and they wanted to support that movement. So there was this great, untapped market of people who wanted to support the local economy and keeping things as environmentally sustainable as possible.

 

 

Challenges to Overcome: NEGATIVITY and RESTRICTING Laws

 

Q: New York is a very densely populated area, which I’m sure brings its own unique challenges to community composting. What challenges have you faced in the city?

DB: One is the lack of the broadest vision of where community composting across five, ten, and then ultimately twenty-five, when we want it to be what it should be. So, as a result of that, people too superficially discount community composting with observations like “well, there’s just not enough land”, or, “Well, we can’t divert all of our organics to community composting, so we have to do municipal curbside pickup.

The other thing is existing laws. Not that there was any bad intention in the creation of these laws. In fact, in New York City, some of the most applicable laws were intended to address the problem of organised crime being involved in the hauling industry. And that’s an important mission, but the unintended side-effect was that the laws impede the growth of community composting – particularly with regard to commercial organics. The current law does not allow those organics to flow unimpeded to community based compost sites.

It’s been very discouraging because there are so many young people, in particular, who are very excited to be environmental stewards and to develop bicycle carting businesses, and things of that sort, and they’re deterred from the outset. And quite often they give up and turn to other environmental work. Hopefully we don’t lose them altogether, in terms of environmental work, but it’s sad that their passions get deterred at the outset.

Q: That is very sad. But there is a petition started now to change the laws? 

DB: There is a petition now. Some folks are trying to get food businesses in the city to ask the city legislators to change these laws. The hope is that it will gain some force. But the problem is that there’s a lot of discouragement, because it doesn’t seem like the policy makers are “there”, and without that kind of support it can be overwhelming.

Q: Hopefully it will work out eventually…

DB: Oh, I think it will. Things are gradually changing. One of the big problems we have had is folks who are able to stick with it and keep trying often look for ways to educate themselves about how to be community composters. And unfortunately, up until now, in the compost industry all the educational materials are geared towards commercial folks. The downside of this is that a lot of people who do community composting will go to these trainings, and they’ll come back thinking that the answer to their problems is machines. So  [they think] the way we can get more done is if we have a bucket loader, or we have a grinder. They start thinking the way a large commercial facility would think.

And I can tell you from personal experience that once machines show up at a site, the people disappear. That’s a big problem when folks start reaching for machines, because then the other goal – to engage the public and get them involved – starts to disappear because the machines are there to do the work and the people see themselves as less relevant, and less important.

But we’re just now starting to get some videos out, and some more information out, that is actually for community composters. Instead of coming from the compost industry, which really doesn’t think about community composters, it’s actually coming from community composters themselves. So there’s more material for other community composters to work with, so that they can keep their focus on people and on community. 

 

 

Wise Words Of Advice.

 

Q: For the final question – what advice can you give our listeners who might be starting their own community composting sites where they live?

DB: Yeah, I think I’d say a number of things. One is that it’s important to find the people who are more interested in action than talking – people who’re not afraid to do work with shovels and pitchforks. I think the danger sign would be that instead, people want to talk about doing a bunch of fliers, making a website, developing stickers, and planning out how to get to thirty different restaurants, or fifty different households.

One story I can tell you is that I had a couple of individuals who were very excited about doing this, and that’s the road they went down. They started making all these big, huge plans that were taking months and months of planning. And I said, “Well, why don’t you try doing a pickup from just one restaurant, and getting that process. Just try that for me to see if you can do that, because if you know you can’t do that, then you shouldn’t be making all these plans”. And it turned out they couldn’t do it.

So, for folks who are interested, that’s a good test. And that leads to my second piece of advice, which is to start small. Many people feel like they have to have it all planned out and go big, whereas if you just start with one or two restaurants, or maybe a dozen households – see if you can do that first, and control odours and rats. And if you can, that’s fantastic and you can build up and get bigger. But don’t spend all this time making big plans, when really you’re not able to pull off the practicalities of it all yet.

And then the last thing I would say is to be guided by a strong vision for what you want to achieve, because so many people will tell you all the different obstacles in the way. Like, “There’s not enough land”, you know, “You can’t have odours, you can’t have rats”. When, if there’s a strong vision which says community composting will be what we have to do in the future, because it’s environmentally the most sustainable and keeps the organics as close as possible in the loop…if you just remember that vision when people say all the negative things, you can say “Well, I know that might mean it takes us longer, but we know we’re going to get there”. And then they can keep up their good spirits. They’re on the right side of history!

12 Days in Benin: A Community Ready for Organics Recycling

TOS_15_Benin_Community_Ready_For_Organics_Recycling

This episode corresponds to Lesson 3 and Lesson 4 of our online course.

In this fifteenth episode, we speak to scientist Dr. Vara Vissa about her short trip to Benin, Africa, and the spontaneous grassroots organics recycling campaign she helped create with the help of local students and community leaders. Vara saw a wealth of opportunities for the local communities in the organic material that lies in makeshift landfills, and discovered that the open-minded and proactive people of Benin are ready and willing to make this change happen.

Thank you to Big Hanna Composter for making this episode possible.

The original since 1991, and now installed in more than 25 countries, Big Hanna’s five standard models of on-site in-vessel composters range from 75 to 2400 kg of food waste per week, for housing areas, prison, schools, canteens and restaurants. For more information, visit www.bighanna.com

(more…)

EM: So Gerry, would you mind just giving us a little background information on City to Soil and give us some background information on how it all got started?

GG: We commenced using City to Soil as a program in 2003/4 in a little town called Queanbeyan, which is next to our national capital. What we were trying to do at the time was demonstrate that we could collect clean, source separated organic waste, turn it into a high quality compost, and get it into agriculture for much cheaper than we could put it into landfill.

And we demonstrated that we could actually do that. We could collect it, process it, carry it two hundred kilometers, and put it at a farm gate for about fifty dollars a tonne, including profit when the disposal fee to landfill was seventy-five dollars a tonne.

The thing that really surprised us was the very, very low levels of contamination. The entire focus right through the City to Soil program has been on the idea that this material is going into agriculture to produce food, so it must be clean. And we’ve found that that message absolutely resonates with people.

EM: Mh-hm.

GG: Anyway, after the first very successful trial, we were given a two million dollar grant to run the program in four areas of New South Wales – four council areas. One of those areas is four and a half hours away from where we are here. If you use the normal method of composting, it would have meant that we would have been loading machinery onto trucks and carrying it from one place to another – we would have used up our two million dollars in a very short space of time. So it was clearly necessary to find a new way of composting.

EM: Yeah – and what was that new way of composting, then, that you developed.

GG: So we really…we developed this process of covering the material and using an inoculant, and it’s been very, very successful. It’s more or less, if you look back at the history of composting, it’s a combination of what the Japanese community call “Bokashi”, which uses effective microorganisms. These inoculants speed up the process, but more importantly they change the biological nature of the compost pile.

These sorts of processes have been used – there’s a very good description if anybody has the old book by Sir Albert Howard called “An Agricultural Testament”, pages forty-eight and forty-nine are almost this process absolutely described, so it’s very much like the original biodynamic composting process as well.

EM: Okay, and maybe you can give us a talk through the actual process? How do you go about it?

GG: So, the composting process that we use for City to Soil, is basically that we’ve asked people to give us clean, source separated product because we’re putting it back into the soil to grow their food. And people really seem to understand that, because our contamination rates are very, very low. We bring the material into the composting site, and we spread it out on the ground. We take out any obvious contamination – and there are things you miss in that first step. And we don’t shred: that’s very, very important. The argument is because we collect our food waste and the garden waste in one two-hundred-and- forty liter wheel bin, all of that material, pretty well most of it will be no longer than you arm and no thicker than your thumb. So most of that material will break down without shredding. If you do shred in that first stage and there’s a bottle that you’ve missed, what happens is you end up with glass, or plastic, all the way through your compost.

EM: Mh-hm.

GG: And then we get it very, very wet; so somewhere between forty percent and sixty percent moisture. Then we inoculate it with the inoculants that we’ve prepared previously. Then we push it up into a pile, we put a cover over the compost pile, and we put an indentation. And what normally happens then is that green waste in that circumstance will go up to about seventy degrees Celsius, so it gets very hot. That heat drives the moisture out of the pile, onto the inside of the cover, if you’ve got a cover on, and all the water runs off because it’s a slope. If you have an indentation in the top, then what it causes is: the two sides of the compost pile will push the water up toward the top, but most of it will drip into the bit that’s indented and fall back into the pile. That actually means that in most instances – not all, but in most instances we don’t have to apply any more water after that first stage. Although sometimes we put more water on in the middle stage, about six weeks into the process.

But then, after the compost goes through the seventy degrees Celsius, the family population – that’s the first stage, aerobic stage of composting, is totally an oxidation process. Once it gets to that peak, all those families change, and they collapse back into the pile and the process becomes fermentative. So it’s a fermentation process, much the same way as you’d make…as a farmer might make silage, or the Germans might make sour kraut, it uses lactobacillus as the principal biological agent. But those biological processes can change quite dramatically in the compost pile.

So then we just leave it for another six weeks. We leave it for six weeks in the first stage, we take the cover off and check the moisture and everything is breaking down quite well, and we may put a bit more inoculant on or we may put more moisture on, and we put the covers back on. We sometimes turn it at that stage, put the covers back on and then leave it for another six weeks – or another twelve weeks if possible, because in that secondary stage the humus in the pile is actually building quite dramatically. We’ve found with our compost process…at the end of this process we’ve had thirty to fourty percent more compost than you’d normally have if you have a totally aerobic process.

EM: Amazing.

GG: In this compost process, what we’re trying to do is make something. Most waste management processes are trying to reduce something – they’re trying to get rid of something. Which is how the oxidation process in compost is quite often looked at from a waste manager’s perspective. What we’re doing is: we are not trying to solve a problem; we are trying to develop an opportunity. It’s a totally different focus; we’re trying to make something beneficial out of something, and we want to return it back to the soil to give an even bigger impact biologically into the soil.

Interestingly, the council in Armidale, one of the five councils where we’re using the process now (they’ve been using our inoculants strictly now for about eight or nine months): the Environment Protection Authority has just given them an extended license to process fifty thousand tonnes a year on their site -which is large for a regional center in Australia – but they’ve made it a condition of the license that they have to use our process. Which I think is wonderful.

EM: Yeah, it really is. It’s a testament to the success of the process then.

GG: Absolutely, yeah.

EM: And so let me go back a bit now and ask you a few more details – can you tell me what kind of covers you use for the compost?

GG: The thing that we found to be best of all is what in Australia we call grain covers. They’re very heavy-duty, – they’re generally used to cover large outdoor piles of rice and wheat in Australia – they’re very durable which means that we can have the same cover for a long time without it deteriorating because of the ultraviolet light. So, it’s important to get something of good value. If you’re going to invest in something, you’re better off spending a couple of hundred dollars on something, because it’ll last years. Sure, you can go out and buy plastic, or you can go and buy a cheap cover, but, you know, it’s gone in six months. So yes, we try to rely on quality.

EM: Mh-hm. And they’re not breathable covers, are they?

GG: No, they’re solid, yeah. They’re actually, you don’t let any air – they entire idea is to contain the microbial processes. You’re trying to create a circumstance where they’ve got a food supply, and they’ve got enormous family members there together. While the food supply and the family members and the right conditions are there with moisture, then they’ll breed up. And in breeding up, they’re creating more humus, they’re pulling more things in from the atmosphere, and they’re creating beneficial outcomes.

EM: Excellent, and how much machinery, then, would it take to run a program like this?

GG: Very, very, little. Our entire objective in designing the process was to have something that really used minimal machinery. I’ve tried to get farmers to use the process because the only thing they need is their tractor. And most tractors have a bucket on the front so they can move manure and things around their farm. So the only things you need, basically, are the tractor and some supply of organic material, and just a simple cover. So, not a complex process.

And the inoculants: if you look up lactobacillus on the internet, you’ll find the start of those processes. Or even better still, go to your locate effective microorganism supplier and buy some of their product.

EM: And you can make the inoculant yourself?

GG: Yeah, I…we made it in a hotel room in Egypt. So, basically the process is: half a cup of rice in a small jar – a honey jar – with water. And you leave that sit for three or four days. It pulls the lactobacillus in from the atmosphere. With a loose-fitting lid: the lid has to be on, you don’t want little animals getting in there because they carry other types of biology, but the air contains the lactobacillus.

So, rice in water, for four days in a dark cupboard. And then you take that water, pour it off into two litres of normal milk – or skimmed, I’ve used skimmed milk, tinned milk, powdered milk, all sorts of treated milk. After about another four days, all the solids in that milk will form a cheese on top, which is about two centimetres thick, or an inch thick, on top. You take off the cheese and feed it to the chickens, or the dogs. Animals love it. It’s beautiful; it’s quite edible stuff, actually.

And then the serum, which is underneath: you dilute that one hundred percent with rainwater, because you don’t want any chlorine in there. If you do use tap water, let it sit for an hour. But dilute it one hundred percent with water, add a cup of molasses, and that’s the basic product. It will stay in that form for about three years without – and quite stable.

And then we take that product, and we extend it again. We turn it into a more extensive product; it can be used as a fertiliser or a compost inoculant or…. The secret to the whole thing, to my mind, is introducing a process that enables the biology to be as diverse as possible. The more diverse the biology in the compost heap, the better outcome you’re going to get in the longer run.

EM: Mh-hm. And the quality of your compost, then, is quite good?

GG: Brilliant! It matches the best of any compost I’ve ever seen anywhere. We have local people here – there’s a company called Ylad, west of us, who sell their compost for about one-hundred-and-twenty-five dollars a tonne, whereas commercial compost in this area, in bulk, would normally sell for about forty dollars a tonne.

The end objective of what we do is to have a product that is biologically active, has high levels of humus, and it uses the compost material simply as a substrate – as a vehicle to carry the biology back out into agriculture.

EM: Excellent, and so because of the nutrient value, you can sell it at a very high price. And can you tell us a little bit about the feedstock now. I know that this process can operate with variable feedstocks – so what kind of materials can you use?

GG: There are a whole lot of different feedstocks that we’ve used in the process so far. Normally in a composting process you have to have a ratio of about twenty-to-one carbon to nitrogen, up to about sixty-to-one carbon to nitrogen.

Using this process, we’ve composted Australian native sawdust, which has a carbon to nitrogen ratio of about one-hundred-fifty-to-one, on its own. Now, the reason for this, and the reason why variability of feedstocks does not matter all that much, is that this process pulls its nitrogen base from the atmosphere.

So after it goes through the first phase, or while it’s going through the first phase, the aerobic composting will normally blow off a lot of nitrogen, but the fermentative stage seems to build a whole lot of things back into the process. So yes, the mix of the materials is not really all that crucial. We’ve done it with pure food in New Town in Wales in 2007 and it worked perfectly, or we’ve done it with Australian native sawdust at the other extreme.

EM: That’s really good – it’s a really good advantage. And now Gerry, can you tell us in what contexts would this process be ideal for, do you think?

GG: Well, in terms of using the process, I think the biggest advantage is that it’s excellent for remote locations. We’ve never, ever said that this process is so unique, you know, it’s better than any other compost process in the world. Composting processes have been around since the dawn of time, and nature is very good at doing it in all sorts of different ways. But what we’ve tried to do is come up with a process that can be used in remote locations, or by farmers, to get a very, very good product.

The process is not that different to biodynamic composting, except biodynamic composting is not generally covered. And this is absolutely simple. If you’re a farmer and you don’t have time – you can set up the compost pile, put the cover on, and just go away for six months.

EM: That’s incredible, so it really requires very little. And the odour issues either, isn’t there not?

GG: Not at all. No odour…no shredding, no turning, no odour.

EM: That’s amazing.

GG: Yeah.

EM: And we know that in order to make good quality compost, you need a very clean source of organics – and you mentioned before that you’d had great success with the City to Soil program – can you give us an idea as to why that is?

GG: The thing, I suppose, that’s really unique about – well, I don’t “suppose”. It is. The thing that’s absolutely really unique about City to Soil is the community engagement process. I think people have got to a stage with recycling programs where they see that when they’re putting their newspaper into bin, or their aluminium (or aluminum, as the Americans would say) into a recycling bin, they’re giving that material away. They pay for the service to have the material collected, and in most instances it goes off to some re-processor somewhere, so they’re giving Rupert Murdoch his newspaper back at a discount price. Or they’re giving aluminium away to Comalco or one of these larger companies. Where…if you put organic material into a bin and it’s being made into compost and it’s going back into soil to produce food – the people see that it’s a very real connection.

I think that what we’ve done inadvertently, and in some ways intentionally – we obviously expected to get very clean material from it – what we’ve done is we’ve hit a button in people that really resonates with them.

We’re operating now in five council areas with City to Soil, and our contamination rate seems to get lower and lower, not worse and worse. Most contamination rates around the world in organics recycling, people think they’re doing really well if they only have five percent contamination. Our contamination has never gone above point-four of one percent. The lowest council – we just started at a place called Palerang. Their contamination level is currently running at point-zero-six of one percent.

So, in a small town of about four hundred people, we collected one-and-a-half tonnes of material and the total contamination were two soft drink cans and one plastic pot. That’s absolutely nothing.

EM: That is really incredible. And for our final question now, because we’re running out of time: can you tell us how you get such low contamination rates? What do you do?

GG: What we collect is garden waste and food scraps together. Now, that’s unusual, but in Australia, our circumstances are relatively unusual. We have four hundred and fifty-five million hectares of land under agriculture. Seventy-five percent of that land has got less than one percent organic material in it, so our soils are very low in organic material.

We have about forty-five million tonnes of waste a year, and about sixty percent of that is organic. So it’s an absolute no-brainer that the thing we should be clean product, and getting it back into our soils.

So to make that as easy as possible for people, we use a two hundred and forty liter wheel bin – a cart for the Americans – into which…we give people a compostable bag which sits on their kitchen bench. Because the compostable bag breathes, it allows water to go out of it, and allows the material to lose a lot of its moisture, but it won’t smell. People then tie up that bag and they put that in with their green waste in a two hundred and forty liter wheel bin.

The difference with our bags, is that when we give a household a roll of one hundred and fifty bags, they all have a number on them. So we can, theoretically, if we’ve registered the number against the street address of the house that we gave it to – we know where that bag came from. But we don’t use it negatively; what we generally do is we’ll wait until we get bags back at the composting site, we’ll pull two of those bags out of the compost pile and if there is no metal, glass or plastic in those bags when we open them, that household wins a one hundred dollar hamper of fruit and vegetables.

We’re trying to make people think about where their food comes from. But, more importantly the fundamental thing about City to Soil is trying to connect the urban population back to the rural population. And that whole link is to try to get people to think about the farmer as their food supplier. Because regardless of a farmer’s religious, political or social beliefs, you need to have a relationship with them because they’re growing your food. And they need security and you need security of supply.

So food is very, very important to us. We say to people all the time: if you eat, you’re involved, you know? It’s a process you can’t avoid. And so…and we think this message can transfer quite comfortably into any language, because it’s a very simple message. It’s just simply saying: clean material goes into your food supply.

EM: Amazing, that’s a great message. Well, congratulations on the success of the program, and Gerry, that’s all we have time for today so…

GG: Alright.

EM: Thanks a million for coming on the show.

GG: Okay, talk to you soon!
