Plastic bags, fruit stickers and other non-compostable
CompostEcology sets regulatory standards for compost facilities and compost quality, and provides technical assistance to local governments. Composting is an important component of "closed loop" recycling. By composting yard debris, food scraps, manure and crop residues, we can turn waste into a valuable resource for farmers, orchardists and gardeners while also reducing the production of greenhouse gases. About 35 percent of waste in Washington could have been composted.

The Washington Organic Recycling Council offers a one week Compost Facility Operator Training every October, at Washington State University Puyallup Research Station. Registration opens each Spring. Upon successful completion of this training, students are eligible for continuing education credits, including 2.9 credits toward Ecology's Wastewater Operator Certification Program
Compost can be used in landscaping, new construction and roadside applications. In Washington, there are soil best management practices for using compost when soil is disturbed on developed land.
Fifty percent of residential garbage in Washington could have been composted! Most of this material consisted of food (18 percent) and leaves, grass or prunings (12 percent). For information on composting classes and education, contact your local WSU Cooperative Extension Office or local solid waste department.
From 2010 through 2015, more than a million tons of material was composted at commercial facilities in Washington. These charts show what materials were composted and how much was produced.
