The Ministry of the Environment holds LHSC accountable for the proper disposal of and reporting of all hazardous wastes through the Hazardous Waste Information Network (HWIN). All chemicals must be disposed of according to our Chemical Waste Control Procedures and LHSC's Waste Management Manual.

In 2019, approximately 43,814kg of chemicals were disposed of as hazardous waste from our labs at LHSC. The majority of this waste was Formalin, a preservative and Xylene, a solvent used in the labs.
