Biosolids Home Partners Biosolids Application Research and Studies FAQs

Roughly 4,500 bulk tonnes of biosolids are produced by the RDN's Pollution Control Centres every year. Since 1999, RDN biosolids have been beneficially used in agriculture, landfill closures, mine reclamation and forestry. Since 2007, RDN biosolids have been beneficially used in Vancouver Island University's (VIU) Forest Fertilization Program.

What are Biosolids?

Biosolids are nutrient-rich, humus-like materials that result from the treatment of wastewater. They contain nutrients such as nitrogen and phosphorous which are vital to healthy and productive soil. In addition, biosolids also have a high organic content which allows the soil to hold more water thereby decreasing run-off and erosion. Biosolids that meet regulatory standards are suitable for use as soil amendments in sectors such as agriculture, landscaping, landfill closure, mine reclamation and forestry.

Why Recycle Biosolids?

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.
