CHAPTER 5: DOOR-TO-DOOR OUTREACH STRATEGIES AND LOBBY EVENTS

 

THE ORGANIC STREAM: We left off episode three discussing Milan’s outreach campaign as part of their roll-out strategy. One of the key ingredients of their campaign was meeting tenants face-to-face in the apartment buildings, or at community meetings. This is the cornerstone of any outreach campaign.

I want to look at this in a little more detail, because engaging tenants is not always as simple as just heading over to the building and knocking on the door. It’s about gaining trust.

In episode two, we discussed in detail the importance of understanding the demographics you’re working with – reaching people where they are – either online or offline, at community gatherings, social media spaces, television, on the street at local festivals, and so on. Also making sure to have native speakers of the different languages on staff is crucial. This can go a long way to getting people to engage and to trust you. But there is more to it than that. Program coordinators have a few extra tricks up their sleeves to get people in apartment buildings interested, engaged, and willing to attend meetings.

Remember Alexa Kielty, member of the residential zero waste team at the San Francisco Department of Environment?

Well, Alexa told me a lot about their outreach work, and I was really impressed. We covered San Francisco in great detail in episode one and two, and as we know their zero waste strategy is one of the most impressive zero waste initiatives. In terms of organics recycling in multi story buildings – all residential buildings with less than six units separate their organics, and eighty percent of large-scale residential buildings do the same. Right now, San Francisco is focusing on the remaining twenty percent to close the gap, and because of this they have started to really hone-in their outreach strategy.

Alexa told me that in San Francisco, staff work directly with building managers to create individualised outreach program for the building – again, this means working with different demographics, customising the outreach materials, and so on. They also go door-to-door to deliver kitchen caddies and outreach materials year in, year out. Because of this, they have some great experience in knowing what to do to gain people’s trust and make it work…

 

ALEXA KEITLY: After we set up the programs, we have a whole outreach team called Environment Now, which is a green careers program – so, somewhat of a job training program. We hire from the community so we get a lot of native Spanish speakers, native Chinese speakers; we have a native Russian speaker and a native Filipino speaker on staff. And those folks will do what we call a Green Apartments, which is essentially door-to-door outreach within apartment buildings, at about five to seven pm in the evening, so hopefully we’re getting people when they’re coming back from work. And we work with the property manager so the tenants know ahead of time that we’ll be there on the certain days; we find out what languages are needed; we send outreach materials to property managers to post within the building ahead of time and in the elevator, so it’s not a surprise visit.

What’s great is if the property manager can come with us when we do outreach, or the resident manager, which is even better because they typically know more tenants. If that person can actually conduct the door-to-door outreach with us that’s really helpful because more people are willing to open their doors if there’s somebody they know.

 

TOS: This is great information here. First off, it seems the most important thing is to make the outreach personal. Alexa says they hire people from within the community they’re reaching out to – people who understand the community and are native speakers of the language of that community. It’s easier to open your door to people familiar to you.

Another thing they do is work with the building manager to give people notice that they’ll be coming, of course.

And finally, and most importantly, the trick to getting people to open their doors is to have a building or resident manager come with them. When we spoke to Lily Kelly of Global Green in her office in San Francisco, she said a similar thing…

 

LILLY KELLY: Having a tenant or a property manager come with us when we were doing the door-to-door outreach initially, especially if it’s a tenant who knows other people in the building, I think we got a lot more people answering their doors because it was their neighbour who’s knocking and saying, “Hey I want to introduce you to this person who’s doing this composting project, we’re going to have this at our building and it’s going to be really great”. I think that really changed people’s perspectives on it right at the outset of, “Oh, this is something my neighbours are interested in.

 

TOS: Gaining trust is a big part of getting people involved and interested in the program. So if tenants can see there’s someone from their building that’s interested, they might be more inclined to listen.

Now, in a big city, with a lot of buildings it’s not always easy to manage or finance such initiatives – which is why it’s a good idea to find recycling champions in the building – either a tenant or building manager and support them in promoting the program. Seattle has a great volunteer program for building managers that does exactly that, the Friends of Recycling and Composting program – and I’ll get into it later in the episode.

Another great tactic is to work with people that have some social significance – popular figures within the community, or local celebrities. This can really boost a program’s image and make it more attractive.

So that’s door-to-door outreach. Now let’s look at open events, or what are often called lobby events.

Setting up an event in the building, where people can come along to get information and perhaps pick up equipment is a common strategy. Many programs do this, and it can work quite well. But to get people to take time out of their day to attend, that requires some strategic thinking.

There are two main tricks you can use that have been shown to give results. And to learn about them, I wanted to take a trip back down memory lane, to one of the first interviews I ever did here on The Organic Stream.

(Clip of old episode plays).

TOS: This is our second episode, when I interviewed Rokiah Yaman and Clare Brass, director of the SEED Foundation, about her food scrap recycling research program that aimed to discover the barriers to organics recycling in urban environments. Clare was working with an inner-city estate, the Maiden Lane estates, in a disadvantaged area in London. And she told me about her difficulties in engaging the residents, who had much more immediate problems to deal with.

But using some clever techniques, she was able to overcome these challenges and get people participating in the program anyway.

 

CLARE BRASS: Recruitment is still the most difficult thing with these projects and you need to get under the skin of the people, your primary stakeholders. Now, often the thing that is driving you, so in our case the environmental challenge of food waste, is not the thing at all which is maybe driving a resident of a housing estate.

The thing that works quite well, and I think this is a really good trick, is that we piggybacked on an event that was happening at the estate. Just when we started the project there was a barbeque event coming up on the estate. We went along to that event, and we set up a stall with a poster. All we did really was go along with a whole stall full of little tomato plants, a bucket of food waste and a bucket of compost, and just talked to people and say “did you know that your food waste can look like this one day, and then it turns into this?” And most people were quite surprised, but it was an opportunity for us to start a conversation with them.

And I think the key thing here is, if you’re recruiting, it’s to go to where people are already going to be going, and just give them a little, a little tiny reward. Just to have a first point of contact. After that we managed to get about 15 to come to our first workshop. So that was a really good way in.

 

TOS: So there we have two of the best strategies for getting people to attend – using existing meetings or events at a building for your own outreach event, and make sure to have rewards. Other programs, such as Seattle, often advertise their educational presentation sessions in buildings as the place where people can collect their free containers. Another really great idea is to provide refreshments, because as program managers have told me – people tend to come if there’s food. So these strategies work really well.

 

CHAPTER 6: FOOD SCRAP COLLECTION EDUCATION STRATEGIES – SEATTLE CASE STUDY

 

TOS: One of the most important goals of an organics recycling program is to change behaviour and to get people to understand the impact their actions will have. Without this, there is no will to carry out the action. And this is where education comes in.

We touched on education before in episode two – focusing strongly on the importance of multi-language education materials.

Today, we go further and focus on the excellent education strategy that Marcia Rutan, Recycling Program Manager at Seattle Public Utilities, employs for their organics program.

TOS: Marcia Rutan has been working in education for a long time and she’s been greatly supported in her work thanks to Seattle’s progressive recycling laws. We learned quite a bit about Seattle’s organics program in the last episode. In 2011 it became mandatory to provide organic carts in multistory buildings, and implemented a full composting mandate for the whole city in January this year. Fines for too much food waste in garbage containers will start to be issued in January 2016.

From researching their program, I was inspired by the work they do to educating people. When I got Marcia on the phone, I wanted her to tell me all about it. And the first thing I asked was to start from the beginning: just what were the basic building blocks of their educational program?

 

MARCIA RUTAN: In terms of education, what we find across the board is that property managers especially appreciate posters that can be placed above the carts. Then we also have labels for the carts, and all of these have pictures as well as wording. And then we have our basic flyers. We use two basic flyers for this program. One is called the Where Does It Go flyer, and it has colour coding for all three waste streams: the recycling, which is blue, the compostables, which are green, and the garbage, which is a grey/black colour. The other flyer then is basically a food plus compostables guideline, which is all green, and it’s just to make it clearer to people what goes into the compost cart since it’s a new program. The flyer also provides a few “why is this important” points, as well as tips for storing and carrying out materials – so it just gives some more information. Those are the two basic flyers that we use with this program.

These are foundational for the property managers. They really rely on those flyers, the labels, the posters and the carts – and they’re all colour coded. And that partly came from…in about 2007 or 2008, we held focus groups with community based organisations. They were primarily constituted of folks who were immigrants or who have English as another language (I won’t say second language, because we know some of these folks have several languages under their belts). But they said they wanted the colour coding, and they didn’t want a “yes” “no” type of poster, which was confusing to them, but just “where do things go” in all categories. So that’s where these informational flyers came out of, and the colour coding.

 

TOS: So flyers, labels and posters are foundational elements for property managers in Seattle. Using focus groups to understand what residents would prefer gave them a better idea of how to design their materials. Colour coding is a crucial element – many cities agree that this is key. It’s easy to understand and transcends any language barriers as well. Another important element that also overcomes language barriers, and for those with reading difficulties, is pictures. And it was Alexa that said to me at one point during our interview that a lot of people, no matter what language they speak, tend not to read the posters – so pictures can really help.

One important thing here I want to bring up is the design of the materials. We often see too many design mistakes – so materials are either overcrowded with information and pictures, the signage is unclear or hard to follow, colours and contrast is also something to take into account as well, because if there is too much going on, or it’s just plain black and white, people won’t want to look at it. The more well-designed, clear and pleasant to look at the materials are, the better it will be.

So – educational tools such as flyers, hand-outs and stickers can be classed as passive education tools. Other very popular passive education tools are promotional tools like door hangers or magnets, and of course websites, apps, and social media.

Now, Marcia mentioned websites and social media as tools they like to use for education and outreach – and this was the same for all the cities we interviewed. In this day and age, when so many of us rely on smartphones and the internet as a primary source of information, having an online presence can make a big difference. The benefits are great. They allow program managers to interact directly with residents, share information quickly and easily, and to answer questions.

There are an increasing amount of platforms online to use to get the message out. The key here is to choose the right platform for your target group – for example, younger generations don’t tend to use Facebook as much as they use Snapchat or Instagram. The DSNY in New York have currently started an Instagram account, to try and reach the younger audience – they also have twitter, Facebook, YouTube and Flickr accounts. So there are a growing number of platforms, and when designing your outreach strategy, it is your responsibility to adapt your strategy.

So these are great passive tools to use in an educational campaign. But what about the more hands-on approach we discussed before?

What interested me greatly in Seattle city as a case study and Marcia’s approach was her use of a more active educational approach. At many of the properties, Marcia conducts one-to-one on-site presentations that seem to go down very well with the residents.

 

MR: And we use that Where Does It Go flyer and we take props with us so people get a hands-on experience with putting things into the right colour bin. So I take two big bags of stuff, I distribute it to folks, teach them how to use the flyer, and then they come and put it into the bin they think it goes in and we discuss it. And this is a very popular game, people really love it. I’m a real believer in multiple educational intelligences: rather than just looking at a printed form, that people get their hands on things, and are kinaesthetic as well – they like to get up and move. So I think all of those are really important.

 

TOS: This idea of providing a mix of different educational methods to help reach people is an interesting one. And practicing the physical act of putting organics in the right bin can definitely help make the lesson to stick in a person’s mind.

With on-site presentations like these, it’s easy to see how they can help build a positive relationship between tenants and the program. It also gives educators a chance to get feedback directly from people, address questions and so on.

Seattle has 5 thousand multistory properties…and half of the population of the city lives in mulitstory buildings. That is a lot of people to reach out to. I asked Marcia if they had the budget to be able to reach everyone this way, and she said no. But what they do have is the volunteer program that I mentioned before…

 

MR: We run a train the trainer program called Friends of Recycling and Composting, where property managers or their designanted representatives come and take a two-hour training to get motivated and educated on where does stuff go and best practices at the property, as well as how to motivate residents. And people provide really high marks on this training program. They say they basically came just to get the free buckets (which we use as a hook to get them there!), but they left actually profoundly motivated to back and work with their residents, so it’s been really effective.

 

TOS: While it’s important to educate tenants, many reports show that the most effective education is focused on property managers. This is why the Friends of Recycling and Composting Program is such a great tool.

But educating building managers and owners is not without challenges.

 

MR: There is quite a bit of turnover of property managers, so we’ll just get them educated and inspired, and then they’ll move on to another property…which sometimes can work in our favour, because then they go on to help that other property get going. But sometimes we just basically lose them. And then there’s also resistance by some property managers: they hide the cart, they don’t want the residents to use it because they don’t want to deal with the ick factor, or they perceive a mess is going to happen. So we have missing carts.

We don’t have a good way to deal with the turnover – we just train, train, train and then like I said, some go on to other properties and help out those other properties to get going. But in terms of resistance – the drivers do report missing carts and we can just sort those and find out what are the larger properties (because those are the ones we go after). And then we target them. We give them a call, we go on site and find out what the barrier is for them to participate. Then we work with them, trouble shoot and provide education – anything we can to help feel more confident to get going. And often it’s that they’re very busy, so it can be a time issue. Another issue is fear, and we just try to deal with those fears. So a lot of those have gotten up and going.

 

TOS: One thing about education is that it’s always on-going. There is no real end to the work that needs to be done. Especially for a city like Seattle – with a program that’s very comprehensive and can still cause confusion over what goes where. We gained a lot of insight into what tools work best for educating both tenants and property managers. But the most inspiring thing to take away from the Seattle case study is their commitment to constantly refining their strategy year after year to help clear up this confusion.

 

MR: We continually listen to our customers. We do have a wonderful “look it up” tool on our website, which is one of the most used links on our website, where hundreds of items are listed and the best disposal practices are provided for, and it’s just so many different materials. So that’s been a big help. And we are also continually listening when people give us feedback about what isn’t working with the flyers, or what might need revision, so each year when we go to revise the flyer, we try to make it more clear and useful for people. You know, it’s not always going to meet everybody’s personal style of education, but we just do our best. We really try to listen to the customer, rather than thinking we’re the experts. We are experts, but we also know that it’s incredibly important to listen to the customer. We learned a lot through the community-based social marketing, we really do employ those principles as much as we can. And so listening to our customers is very key.

 

CHAPTER 7: TRACKING RESULTS IN YOUR PILOT PROGRAM – LOS ANGELES CASE STUDY

 

JASON SANDERS: We’re in the Old Bank District Buidling right now, we’re on the eight floor. And we’re walking into the refuse room…and they’re out of compost bags in this one…

 

TOS: We’re back with Ecosafe Zero Waste’s Jason Sanders and Jessica Aldridge of Athens Services in Los Angeles.

 

JS: So we have two compost bags in here, and…we do have one aluminium can.

 

TOS: Here, we’re following them as they conduct their monthly inspections of the trash rooms on every floor of the Old Bank District Building.

 

JS: We do monthly site visits here to check each floor, and we mark down the odour level, the cleanliness level, contamination level, participation, and what the bag count looks like in the dispenser system.

 

TOS: Tracking results. This is one of the most valuable tools to have in an organics recycling program – especially a pilot program. The types of information to track can be materials collected, contamination rate, challenges faced, key contacts, and the amount of outreach employed. Compiling a detailed history of all these factors will be invaluable in moving forward, and to give accurate information when presenting program results.

In LA, we were impressed by the strength of their tracking system and their hands-on approach.

 

JS: So what we’ve seen so far with this program is a high level of participation and a low contamination rate. To this date we’ve done three site visits, and on each of those three site visits we have one or two standard traditional poly bags in the compost bin, and that’s it.

TOS: As you can see, by tracking results in person, Jason and Jessica have a much clearer understanding of how successful their program is. By visiting the building in person, they have a chance to spot problem areas and recognise trends in the buildings.

Of course, one of the most important things to track is the contamination rate. Keeping an eye on how contaminated the stream is, and being able to react quickly to any issues is useful – especially for the processor who will be dealing with the materials on the back end.

 

JESSICA ALDRIDGE: From the hauler and the collector and processer’s standpoint, we have to make sure that the material we’re collecting is good material. And I would say one of the hardest programs to enact is a multi-family separation program, especially for organics. So through this process we want to keep a very watchful eye on that product to make sure it’s as clean as possible. Because if we’re processing this material and it’s making its way back to our sort line – so, when it comes back to materials recovery facility, we have a sort line that it goes up to and the material that’s not supposed to be in there is pulled off. Then it is shipped off to our compost facility in Victorville, it is screened once again, then it is composted and that compost is then screened once again.

So we want to make sure that we have as little an amount of contaminants as possible, or else we end up with a more strenuous process. And also, it gives us an idea of if we need to send out more education and outreach to the residents here, to the management or to the maintenance – whatever it may be. So that also directs how we’re going to move forward with the program.

 

TOS: So, tracking is not only is useful to help you to understand and optimise your program, but it can also help shape your program as well. Frequent site visits are an excellent way to keep a close eye on what’s going on and allow you to quickly react to any problems that come up.  This is extremely valuable – especially for pilot programs that are looking to expand in the future.

 

CHAPTER 8: HOW POLICY CAN SHAPE YOUR ORGANICS RECYCLING PROGRAM

 

TOS: Every organics program is shaped by the regulatory structure it exists within. It can be supported by this structure, or it can be hindered by it. Throughout the show, we’ve come across examples of how policy has impacted on the programs we’ve covered. And it is no coincidence that the cities we chose for our case studies have some of the most progressive laws and policies in place today.

Places that put in place ambitious recycling targets, landfill or incineration diversion goals, or bans on organics going to landfills or incinerators as part of a sustainable waste management strategy are really important. They can create the necessary leverage needed to push for organics recycling. When supported and enforced properly, they can be a critical driver for collection programs. Every city we spoke to has a zero waste vision, or a zero waste commitment, with ambitious recycling targets. Most notably San Francisco – which leads the way in terms of ambitious policy – with just five years to reach zero waste in 2020.

Financial tools used by policy makers to promote organics recycling are important. Pay-as-you-throw systems for waste have been shown to greatly increase participation in recycling schemes in municipalities all around the world. And it makes sense: If buildings are charged more for waste collection than food scrap collection, it gives managers direct financial incentive to participate in the program.

 

ENZO FAVOINO: Bring systems never work as effectively as kerbside systems do. The true springboard towards zero waste has always been the implementation of a kerbside scheme targeting also the organics. With such a system, you quite easily jump up to seventy or eighty percent separate collection. Then, after that, in order to move further towards one hundred percent, what we do next is the implementation of a pay-as-you-throw scheme. And this increases separate collection by a further ten percent, but also it remarkably decreases the overall waste arisings.

 

TOS: But in a city where buildings are serviced by private haulers, municipalities can’t always control the price of collection. In some cases, where landfills are publicly owned, they can control how expensive it is to send the waste to these public facilities. Municipalities may also be able to raise tipping fees for garbage, and tax rates for landfilling or incineration, so that recycling once again becomes the more desirable option. This in turn will mean buildings are charged more for garbage collection and give them a reason to start composting!

There are also policy measures that indirectly impact on programs – which we saw in the case of Milan with the ban on chutes and the plastic bag ban that led to biobags becoming more available.

But perhaps what had the greatest impact on the cities we covered are mandates that require composting, or that organics stay out of waste bins.

 

MARCIA RUTAN: Basically we mentioned the two policies that have been the most critical: one requiring properties to subscribe, which was September 2011 – and that definitely had some impact but it had no enforcement quality to it, so it was not as strong as the new law which started this January that says no food waste in the garbage. And with that associated fine, that has had a very big impact on the properties wanting to participate.

 

LILY KELLY: When there’s an ordinance, or when there’s a law that requires composting, it really makes a difference. Just listening to the property managers changing their narrative it from, “Oh, I don’t know if I want to compost, it seems gross and smelly,” to, “How do we make this work?”

 

TOS: While it’s not a fix-all solution, the financial incentives that come with mandatory measures can make a huge difference – nobody wants to pay a penalty for not recycling properly. In multistory buildings, fines that are shared equally among tenants can help combat the anonymity factor. Enforcing these fines work best with a kerbside system.

Those are some of the key policy measures we’ve come across in the cities we’ve covered that have had a direct positive impact on programs. Having a strong policy framework will help steer everyone in the right direction, but it also has another great effect. It leaves program coordinators free to concentrate on doing their job, as opposed to spending their time fighting to change things for the better:

 

MARCIA RUTAN: Seattle is just a really leading-edge city in this. The agency I worked at previously had a pretty good program, but I always felt like in some ways I had to fight for recycling and composting to continue. Whereas when I’m working with Seattle, I basically feel like I’m swimming as fast as I can to catch up. And it’s wonderful! I can go as fast as I can to do as much as possible and there’s still room for opportunity. It’s really great!

 

FINAL CONCLUSION

 

So we’ve come to the end of our show, and it’s been a great journey. We’ve covered a lot of ground on this topic and there is a lot to take in.

But what we’ve seen through this show is that while multi-residential organics programs have their challenges, it is very possible to roll out a well-running, successful scheme.

The success of the programs we covered is a result of careful planning of the system, building strong relationships with key partners, working with building managers to find solutions, spending time with focus-groups to craft a successful outreach campaign, investing in communication, and taking a step-by-step approach to implementation.

They each use a combination of different strategies – all tailored to suit the needs of the specific building, or area, that they’re targeting. Your program’s success is predicated on your ability to execute consistently all the strategies we discussed, and to continually measure and improve your approach as you go along.

And in the case of Milan especially, we can see that with the right system and approach, and a supportive policy to back it up, organics recycling programs in multi-residental buildings can be rolled out with no more difficulty than any other organic recycling scheme.

So while multi story residential buildings can be a challenge for many cities, combining the wealth of experiences and best practices from the leading cities, we have a great roadmap to guide us on our journey.

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.
