About hazardous waste
Hazardous wastes are primarily generated by industrial and manufacturing processes. These wastes include a broad range of materials such as:
- materials from manufacturing (e.g., waste acids, contaminated sludges and chemicals)
- biomedical wastes from hospitals and other health care facilities
- photo-finishing chemicals
- waste pesticides
- polychlorinated biphenyls (PCBs)
- motor oil
- unused cleaning products from homes
- discarded batteries
Hazardous wastes require special handling to reduce adverse effects to human health and the environment.

The Ministry of the Environment has a cradle-to-grave management system which controls:
All hazardous waste generators must register to provide the government with a record of:
- who creates hazardous waste
- where it is generated
- what hazardous wastes they generate
To register go to: Hazardous Waste Information Network (HWIN)
All off-site movement of hazardous waste and liquid industrial waste is tracked using a manifest.
- accompanies the waste from its point of origin to its point of disposal
- describes the waste
- shows when it changes hands between generators, carriers and receivers
If you are a carrier or receiver of hazardous waste or liquid industrial waste, you must obtain Environmental Compliance Approvals from the Ministry of the Environment outlining the specific conditions of your operations, including wastes you are approved to manage safely.
