Poop Loop Biosolids and Sustainable Agriculture

SUMMARY: The key to building good soil is reusing our own poop. King County’s wastewater treatment plants break down and transforms the poop and the food that we flush every day into an endlessly renewable resource to build our soil. King County calls these biosolids Loop®. By using Loop to grow crops and healthy forests, we return carbon and nutrients to our land, which helps us fight climate change and farm sustainably.
