Composting Roundup
BioCycle June 2011, Vol. 52, No. 6, p. 12 Washington, D.C blanket approval for compostable plastics in organic production. The letter was in response to comments received at the public meeting asking the NOP to clarify its position on bioplastics in compost destined for certified organic production and to suggestions that the board accept as allowable any products meeting ASTM D6400 and D6868 and Biodegradable Products Institute (BPI) compostability standards. McEvoy wrote: “Several commenters asked that NOP address the use of postconsumer food waste, such as compostable plates, cups, cutlery and plastic bags. We agree that this is a new development in handling food waste, but we believe that these represent synthetic materials that would need review and recommendation by the NOSB before they can be utilized in compost for organic production. Members of the public may wish to file petitions for consideration by the NOSB for these types of materials as compost feedstocks. Instructions for the preparation and submission of petitions are provided at http://www. ams.usda.gov/ NOPFilingaPetition.” The Washington Organic Recycling Council (WORC) presented a proposal to NOSB while the board was having its meeting in Seattle. “The proposal was to not require all synthetic foodware products to have to be individually evaluated for inclusion but rather use the ASTM test methods,” says Jerry Bartlett of Cedar Grove Composting, the official composter for the city of Seattle and a WORC member. “We were trying to avoid the petition process for each synthetic compound. The USDA rejected the proposal, and so it is now the manufacturers’ responsibility to go through the petition process with each synthetic item they want to be composted.” The WORC letter had stated: “WORC recommends that the National Organic Program approve compostable products that meet ASTM Specification Standards D6400 [and] D6868 as feedstocks suitable for incorporation in compost products registered for use in organic agriculture. This action makes sense for all vested parties: it will lessen the burden of feedstock segregation and management currently placed on composters, generate increased volumes of products desired by organic farmers and gardeners across the country, and not yield any significant risk to the environment or consumer.” BPI and some manufacturers continue to explore ways in which the NOP might be convinced to adopt ASTM testing protocols. Compost Quips Salt Lake City, Utah What Blake attributes to observation and experience is the realization that compost made with food waste seems to retain more macro and micronutrients than manure-based compost. “A cow or a chicken or a turkey has already digested all of those nutrients,” says Blake, explaining that EcoScraps accepts fruits and vegetable waste only and does not work with potentially contaminated green waste such as lawn clippings or landscape debris. For a carbon source, the company takes in wood shavings from local lumber mills and some coffee grounds. All composting is done indoors, with piles moved once every three days via an industrial-sized snow blower. According to Blake, it only takes three weeks from when produce scraps are delivered to the facility and mixed with wood chips and mineral amendments to when the finished product is bagged and shipped to retailers. EcoScraps has two production sites — its 5,000-sq.ft. facility in a converted steel mill in the industrial district in Salt Lake City, and a 6,000-sq.ft. facility in Tempe, Arizona. Feedstock flow to both plants totals 40 to 60 tons/day of food waste from more than 70 Cosco outlets, grocery stores and produce wholesalers throughout Arizona and Utah. Haulers delivering source separated organic residuals to its facilities receive a substantially reduced tipping fee from what they would pay at local landfills. A discounted rate is also given to clients who separate produce scraps for pickup via the company’s own trucks rather than contracting with conventional trash haulers. A total of 35 to 40 cubic yards/day of compost is produced. Bagged compost (1 cubic foot) wholesales for $5 and retails for up to $8.50 at garden centers and nurseries throughout the West. Each bag carries a minimum macronutrient promise of .5-.15.-.5 (NPK) with a pH of 6.5 and a moisture content of 33.85. Recently EcoScraps has been talking to Walmart about both carrying the fledgling company’s compost and helping the giant retailer meet its stated goal of diverting all of its organics from disposal. Salinas, California Bend, Oregon The IGA donates produce that can’t be sold due to slight bruising or blemishes but which is still edible to food pantries in the community through its Gleaner Program. Produce and other food waste that’s no longer edible is earmarked for the composting program. Cascade Disposal provides secure containers to dispose of each department’s food waste, including meat, vegetables, seafood, bakery items, eggshells and coffee grounds. The contents are picked up weekly and delivered to Deschutes Recycling, where they are composted and screened to remove oversized material. The resulting compost will bear the U.S. Composting Council Seal of Testing Approval and will be available for purchase by the public. “We are saving approximately $100 per month, but more importantly, we have the satisfaction of knowing we are helping reduce the amount of waste going into the landfill,” Newport Ave. Market owner Rudy Dory told the Progressive Grocer. “It is helping to create jobs and doing the right thing for the neighborhood, community and environment.” Copyright 2011, The JG Press, Inc. |
