Loop® biosolids
Turn your dirt around
The King County Biosolids Program manages the distribution and use of Loop®, our name for the nutrient-rich organic biosolids product created by recycling the poop in the County’s wastewater. Loop is a natural soil builder and endlessly renewable resource that returns carbon and nutrients to the land. Simply put, it is good stuff that builds good soil.
