Where are those trucks going?

August 31, 2017

If you drive or live along Interstate-90, you’ve probably seen this truck on the road. You have probably wondered what it is carrying, and where it might be going.

Each one of these trucks carries about 31 tons of an endlessly renewable resource that returns valuable nutrients back to the soil. Loop® is a fertilizer-like product recycled from the waste that we send down drains and toilets.

While a small amount of Loop biosolids is turned into a garden product called GroCo compost, most Loop trucks are headed to farms and forests. Farmers and foresters have used Loop for decades to grow healthy crops and trees. Every day of the year, 10-15 trucks travel to approved sites across the region. As long as people in King County use those drains and toilets, we will find beneficial uses for recycled resources.
