What are Biosolids?

Biosolids are the solids that result from municipal wastewater treatment and meet strict requirements outlined in the Organic Matter Recycling Regulation. Because of their stabilized, nutrient-rich, and humus like properties, biosolids provide a sustainable alternative to chemical fertilizers as a means to improve soil fertility where nutrients are limited.

Why Recycle Biosolids?

Biosolids contain nutrients, such as nitrogen and phosphorous, which are vital to healthy and productive soil. Biosolids also have a high organic matter content that allows the soil to hold more water, thereby decreasing run-off and erosion. Biosolids that meet regulatory standards are suitable for use as fertilizer and soil amenders.

Recycling biosolids returns nutrients to the land. Recycling our biosolids makes good environmental and economic sense. The alternative to recycling biosolids is disposing of biosolids in the Regional Landfill. With space declining at the Regional landfill, diverting biosolids from the landfill is consistent with the RDN's Zero Waste policy.

Since 1999, RDN biosolids have been beneficially used in agriculture, landfill closures, mine reclamation and forestry.
