The Ministry of the Environment (MOE) supports the use of environmentally protective and beneficial options for managing all types of biosolids including sewage biosolids and pulp and paper biosolids. Ways they can be used include land application, renewable energy production, mine remediation, and further treatment options for land application such as pelletization and composting.
Municipalities, pulp and paper mill companies and other biosolids generators are responsible for choosing which biosolids management option best suits local situations, as long as the option meets provincial standards. As of January 1, 2011, the Ministry of Agriculture, Food and Rural Affairs (OMAFRA) is responsible for issuing approvals for agricultural land application.
