Award for Biosolids Management

We were presented with the prestigious Water Environment Association of Ontario (WEAO) Exemplary Biosolids Management Award. The award recognizes those who go beyond and raise the bar in the management of residuals and biosolids in Ontario. Biosolids are a nutrient rich by-product of municipal wastewater treatment, and we have been treating them since 2007. Our Niagara Biosolids plant supports the Region of Niagara and the City of Toronto with the management of their biosolids.

The plant uses N-Viro® technology to process these organic residuals from wastewater treatment plants and turns them into a safe, nutrient-rich fertilizer known as N-Rich®. Farmers across Southern Ontario value N-Rich® for both its nutrient content and pH adjustment properties.

Over 30,000 tonnes of N-Rich® have been sold as fertilizer.
