About the CompostWise program

Applying compost improves environmental outcomes for the King County region. It aids agriculture, horticulture and landscaping, stormwater management, ecosystem conservation and restoration, and contaminated site remediation. It helps us close the loop on the organics circular economy by supporting waste reduction and cultivates local green jobs.

King County’s CompostWise Program works to bolster the regional compost market. We do this by providing education, training, technical assistance, and resources to help you improve your soils through the use of compost. We also lead by example by procuring and using food and yard waste compost in King County projects.
