Managing your hazardous waste


Hazardous waste contains substances that are harmful to humans and the environment. It is directly harmful or toxic, corrosive, explosive or flammable. When stored or handled incorrectly, it can be harmful to the environment or health.

The following is considered to be hazardous waste:

  • agrochemical waste
  • degreasing waste that contains solvents
  • sludge and solid waste that contains hydrocarbons
  • hydrochloric acid
  • salts and solutions that contain cyanide.

As producers and owners of hazardous waste, you are subject to the following obligations:

  • to store hazardous waste with a cover, in a sealed area and in closed containers with a clear indication of the waste being stored
  • to entrust the waste to a collector that has been approved by Wallonia
  • to record the waste produced in a register (quantity, type and date of removal by the approved collector)
  • to declare the waste produced to the Soil and Waste Department.

Key points

  • Some hazardous waste is subject to specific obligations. This particularly concerns asbestos and waste oils.
  • The leftovers of hazardous products, their packaging and utensils that have been in contact with said products are also considered hazardous waste.
