Hazardous household waste (HHW) must be disposed of safely. It cannot be put out with other garbage or recyclables. Find out how to get rid of it.

Guidelines to follow

Hazardous household waste (HHW) can be harmful to health and the environment if it is used, stored, mixed with other products or disposed of improperly. It must not be put in household waste or with recyclables for collection.

  • Put your HHW in the trunk of your vehicle. Make sure that each product is stored separately (no bulk), in a waterproof container. For example, pool chlorine must be kept separate from other products.
  • Show proof of residence in the Greater Montréal area.
  • Turn off the vehicle’s engine and open the trunk so that employees can remove the products.
  • If you need to give the employees any information, please do so while remaining in your vehicle.

Ecocentres

You can take HHW to an ecocentre.
