For the past 40 years, gardeners, landscapers, foresters, and farmers across Washington state have used Loop® biosolids to enrich their soils and grow healthy plants.

The King County Biosolids Program has built ongoing partnerships with its customers to establish sustainable and beneficial recycling programs for commercial agricultural and forestry applications. Compost made with Loop has also enriched local landscapes since the program began. Today, the King County Biosolids Program continues its legacy of using 100 percent of the Loop biosolids it produces.
