In Boulder County, Colorado, the name Eco-Cycle has long been synonymous with recycling. Founded in 1976, Eco-Cycle remains one of the oldest and largest private nonprofit recyclers in the country. Recognizing that recycling is only part of the picture, however, Eco-Cycle is now going beyond recycling and into the world of composting.
“Recycling rates are stagnant at about 30% through the recovery of traditional materials – paper and containers,” explains Executive Director Eric Lombardi. “To fulfill our mission of maximizing diversion from the landfill, we have to go after the rest of the waste stream. With about half of the remaining waste stream consisting of potentially compostable materials, we need to start composting.”
The landfill tipping fee in the Boulder area is ridiculously low at a mere $12 per ton. Thus Eco-Cycle’s entry strategy into composting needed to be carefully planned. We took a four-pronged approach: Initiating a commercial food residuals collection program; Exploring options for a compost site in the ever more densely populated Boulder area; Creating high-quality compost products to gain marketing experience; and Educating the community about the importance of recovering this valuable resource.
Successful Collection Pilot
Beginning with a grant of $8,470 from Boulder County to help offset some of the extra overhead costs, Eco-Cycle launched a six-month pilot program in February 2004 to collect commercially-generated compostable waste from a limited number of diverse businesses in Boulder. The focus of the pilot was intentionally narrow: To teach all employees in a participating business the importance and value of proper source separation of compostables from trash for the purposes of maximum diversion and ultimately for the highest quality compost.
The pilot began with nine businesses and institutions, including restaurants, cafeterias, flower shops, a small grocery co-op, and one small manufacturer, a local chai brewer (this is Boulder, after all!) Over the course of six months, the number of participants grew to 14, including the dormitory cafeterias of the University of Colorado, where university officials wanted to begin practicing source separation in their kitchens in preparation for the inauguration of their own in-vessel composting operation. To do the actual composting, Eco-Cycle partnered with A-1 Organics, a well-established composter with a site in an adjacent county 18 miles from central Boulder.
It was a given that hauling efficiencies would be poor during the pilot. Eco-Cycle used a box truck with a lift-gate to collect full toters from businesses on a once or twice a week schedule and then hauled 20 toters at a time to the A-1 composting site for manual unloading. Participating businesses weren’t charged for the service while Eco-Cycle learned what kind of diversion rate to expect from the different types of businesses.
As the pilot phase wrapped up in September, participants saw a 30% decrease in their garbage, and were thrilled to see resources move from the trash bin to the recycling bin.
Eco-Cycle is now transitioning into a second phase of the program, expect to last another six to eight months, during which they will test the revenue and expense assumptions established during the pilot. Because of the high recycing ethic and environmental awareness in Boulder, Eco-Cycle expects there are a certain number of businesses willing to pay extra to support the program, but eventually, they will want to see a bottom line result.
Says program manager, Dale Ekart, “We’d like to see if we can bring the total number of participants to around 50 in the next phase. From the pilot results, we project our costs will be around $11-12 per pickup. The standard charge to participants for the service will be $15 per pickup. If we can divert enough waste from the trash that participants can either reduce the frequency of trash service or the size of their dumpster, overall waste service costs will remain constant.”
Whole Foods Market recently signed up for the service, adding a designated roll-off compactor specifically for compostable waste from all departments of its Boulder store, its largest store by volume in the country. In the first two months of participation, the store composted 67% of its total waste. With recently completed additional training, they expect to meet their goal of 70% diversion in the near future.
The Cheap Disposal Challenge
Central to the long-term success of the composting service is the improvement of hauling efficiencies. Eco-Cycle purchased a used rear-load packer truck that has taken over the food residuals route. Ekart will be closely monitoring the number of pickups per hour, expected to be somewhat fewer than a standard trash route.
Flexibility and lean operating costs will be paramount because though people in Boulder tend to want to do what’s best for the environment, they are used to paying some of the cheapest landfill disposal rates in the country. The tipping fee at A-1 is $16.50 a ton (compared to the $12/ton landfill fee). Add to that the extra hauling distance and time, and Eco-Cycle has quite a challenge making the program cost-effective.
With no operating landfills in Boulder County, the old adage, “out of site, out of mind” is extremely difficult to overcome. The nearest operating landfill, just over the county line, recently won an expansion of over 100 acres with virtually no notice in Boulder. Without knowing or understanding the alternatives, Boulder residents will be sending their compostable trash to the landfill for many years to come, ensuring the emission of methane and other greenhouse gases and the pollution of groundwater for generations.
Standing to a testament to the problems landfills inevitably create, a landfill-turned Superfund site just outside the Boulder city limits has cost Boulder taxpayers nearly $5 million and counting in clean-up costs since it was shut down in 1991 by Subtitle D regulations. Unfortunately, this too is large ignored or forgotten.
Yet on our side of the county line, opportunities to find a few acres for composting are few and the possibility of neighborhood opposition is real. Advocating for a site is a challenge almost on the same scale as trying to convince people to recycle newspaper was nearly 30 years ago.
Community-Building to Reach Our Goal
Unlike siting, good compost can sell itself. The key to reaching our goal is to make the connection in people’s minds between healthy soil, good local food, and their own compostable discards. Boulder is home to a flourishing farmer’s market that is popular in large part because its structure highlights local growers and the importance of local agriculture. So to begin building visibility for our composting program, Eco-Cycle purchased a 25-gallon compost tea brewer, set up some plant trials to demonstrate the effectiveness of compost tea, and staffed a booth at the farmer’s market.
Our positive trial results drew plenty of interest and customers had a great time experimenting with tea on their gardens and lawns. We sold our product for $6 a gallon, and before noon on the first day, we realized we had to buy a 100-gallon brewer to meet demand. Most importantly, the tea proved to be the community conversation piece we had hoped for to start building community enthusiasm for our composting vision.
We plan to expand our work at the farmer’s market next year by making it the nation’s first Zero Waste Farmer’s Market. We will add vermicompost and composting worms to our sale inventory and expand our testing of compost tea with local growers and perhaps some plots on
City parks or golf courses. And some day soon, we’ll have finished compost to sell.
