CEDAR GROVE COMPOSTING ANNOUNCES DIGESTER TECHNOLOGY SELECTION
Cedar Grove Composting, a long-time organics processor in the Seattle region, has been evaluating several anaerobic digestion technologies to process food waste and yard trimmings at its Everett, Washington facility. In early July, the company announced that it is working with BIOFerm Energy Systems, owned by the Viessmann Group in Germany, to integrate high solids digesters into its composting operation. The first phase is being designed to process 50,000 tons/year. Cedar Grove is in the engineering and design stage, and hopes to begin construction by the end of 2010. The permitting process with the Puget Sound Clean Air Agency and the Snohomish County Public Health Department is also underway.
The Everett facility receives about 225,000 tons/year of yard trimmings, wood and residential and commercial/institutional food waste and soiled paper. Cedar Grove utilizes the GORE Cover composting system, which is operated in three phases — two covered and one uncovered. Once operational, digested material will go directly into the second phase of the GORE system, creating more processing capacity on the composting pad. “Cedar Grove is moving into the next realm of its development, the creation of green energy from food scraps that were once destined for a landfill,” says Steve Banchero, CEO. “We are looking to secure contracts for sale of electricity or natural gas in order to complete our digester business plan.”
