What are biosolids?
Biosolids are nutrient-rich, processed organic material derived from wastewater treatment. They contain nitrogen, phosphorous, organic matter and micro-nutrients such a zinc, magnesium and copper, all of which are essential for crop growth.
Municipal wastewater treatment facilities separate the liquid and solid portions of wastewater. The solid portion undergoes biological treatment during which organic material is digested, or stabilized, by micro-organisms. Upon completion, biosolids must be analyzed for acceptability. This ensures that biosolids meet the quality standards, set by the Province of Ontario, and are suitable for land application.
Biosolids are a means to help municipalities reduce input, infrastructure and disposal costs, and to provide a cost effective way for farmers to meet the nutrient requirements for field crops.
