Composting Essential To City's Waste Diversion

摘要

Odense Environmental Center (OEC), owned and operated by the City of Odense, Denmark through the Odense Waste Management Co, is an integrated waste management facility that includes composting, sorting and recycling, treatment of oil-contaminated soil and landfilling. OEC started composting yard trimmings from its parks and gardens in 1998. Finn Andersen is responsible for the windrow composting operation. He uses a computer program to determine the right mixture of biosolids, green waste and straw. The composting process takes eight weeks, with windrows turned once a week. Annual compost production is about 35,000 metric tons, most of which is used as fertilizer for agricultural crops, such as grain. Finished compost is screened to a 1-inch particle size. Show less
