Makers and users of King County’s biosolids share stories

The people who make resources from wastewater, and those who appreciate their efforts, will share first-hand experience with biosolids in a series of upcoming videos.

Scientists, farmers, and environmental educators, along with employees from the county’s Wastewater Treatment Division, appear in six 60-second videos that highlight the value of Loop biosolids, from nourishing eastern Washington wheat fields to sequestering carbon and fighting climate change.

The first video released today tells the story of a young mother, avid gardener and soil scientist talking about growing her own food using GroCo compost.

Produced by King County’s regional wastewater treatment plants for nearly 40 years, Loop is a natural soil amendment and endlessly renewable resource that restores carbon and nutrients to the land for the good of plants, people and Puget Sound.

Gardeners and commercial landscapers value the Loop in GroCo compost because it’s a source of nutrients that build soil and boost plant growth. GroCo is free of weeds and pathogens. It also aerates soil, retains moisture, and naturally helps plants grow bigger and better.

Besides building healthy soils, Loop reduces the need for synthetic fertilizer, sequesters carbon, and helps to offset the greenhouse gas emissions equivalent to taking 8,000 cars off the road each year.

Additional videos will be posted to and YouTube over the coming weeks.
