Biosolids are mostly organic solids resulting from the treatment of wastewater. They have undergone additional treatment to kill pathogens and stabilize the material for recycling. During treatment, bacteria and other tiny organisms break sewage down into simpler, harmless organic matter. The organic matter combined with bacterial cell masses settles out to form biosolids. This organic matter is rich in such nutrients as nitrogen and phosphorus and contains other supplementary nutrients, including potassium, sulfur, magnesium, calcium, copper and zinc. Biosolids have been approved by the U.S. Environmental Protection Agency (EPA) for land application as a fertilizer and soil amendment and for composted products.
Biosolids are used across North America and in most developed countries around the world
VBC has partnered with Virginia Tech to develop Fact Sheets on frequently asked questions concerning biosolids and their use. Recently, working with Dr. Vijay Chaganti, Assistant Professor & Extension Specialist at Virginia Tech’s School of Plant & Environmental Sciences, VBC recently updated several of its fact sheets with up-to-date research. These fact sheets provide information on how biosolids benefit soils and crops as well as emerging matters.
Below please find the most updated fact sheets, including PFAS and Biosolids, on the VBC website.
