At the city’s écocentres, gypsum waste is deposited in the same containers as other recyclable building materials. As a result, it may be contaminated by these materials.

As part of a pilot project that will run until August 2022, the Écocentre Saint-Laurent is handling gypsum separately from other construction debris. This sorting process improves the quality of recycled gypsum and increases its potential for reuse. Gypsum powder is recycled into a product that enriches farm soil, and paper is recycled into absorbent material that is used by pumping companies and commercial garages.

To ensure that the gypsum is clean and contaminant-free, please separate the gypsum from your debris before bringing it to the Écocentre Saint-Laurent.
