What role does King County play in recycling biosolids?
King County’s biosolids management program recycles biosolids as a source of nutrients and organic matter in forestry, agriculture and other soil improvement projects; a portion of our biosolids is composted with sawdust for use in landscaping and gardening. King County is committed to recycling 100% of the biosolids we produce — about 112,000 tons annually. The biosolids program emphasizes beneficial use of this resource and pursues environmental stewardship through diverse public-private partnerships. King County is a member of the Northwest Biosolids Management Association which provides collaborative research, technical assistance and public information for biosolids managers in the region.
