Biosolids 101 - Sorting Through the Muck

Biosolids. In the United States, more than 19,000 municipal treatment facilities generate 7 million dry tons of this nutrient-rich material every year. They spend $1.1 billion to treat and dispose of the stuff. Over 80 percent of it is recycled and reused.

As the numbers suggest, biosolids management is a significant industry in and of itself. It is closely regulated by federal guidelines, and supports a widening variety of technical solutions.

What follows is a primer on how to sort through the muck and find the right technical solution to treat biosolids so they can be beneficially recycled to the environment.
