Ministers approved the Canada-wide Approach for the Management of Wastewater Biosolids on October 11, 2012. The Approach encourages the beneficial use and sound management of biosolids.
Biosolids result from the treatment of wastewater which removes the solids (sludge) from the liquid effluent. Canadians produce more than 660,000 metric tons of dry stabilized biosolids each year. The annual cost of biosolids management is approximately 50% of the total operating cost of wastewater management.
