Weighing The Value Of Biosolids As Fertilizer

Wastewater treatment plants process tons and tons of sludge every year and they have to contend with the question of what to do with it. Increasingly, biosolids are looked at as an opportunity to help the planet.

“Biosolids are created when sewage sludge obtained from wastewater plants is processed and treated, with the finished result being a nutrient-rich material that can be used to ‘maintain productive solids and stimulate plant growth,’ according to the U.S. Environmental Protection Agency,” reported the Niagara Gazette.
