The treatment centre for organic waste (Centre de traitement des matières organiques -CTMO), located in Saint-Laurent borough, transforms garden and food waste into compost, using high-end equipment that maintains good air quality.

The CTMO opened in September 2024. It services the West Island’s related municipalities and the following boroughs: Pierrefonds-Roxboro, Île-Bizard–Sainte-Geneviève, Lachine and Saint-Laurent. It has the capacity to process immense quantities of organic materials from organic and food waste collections.

LEED Gold certification – protecting the environment through technology

The centre is LEED Gold certified (Leadership in Energy and Environmental Design), a certification of the Canada Green Building Council.

Composting is done inside a closed building, using state of the art machinery that prevents the release of odours and harmful airborne particles.

Up to 50,000 tons processed every year

The site has an enormous capacity – 50,000 tons per year. The current use of brown bins is largely inferior to the quantities that the CTMO can process for optimal operations.

If you wish to do your part, but do not have a brown bin, you can request one.

Quality material used locally

The material produced is BNQ 0413-200 certified and is unrestricted. Compost is rich in nutrients and improves soil quality and fertility. It may be used for agriculture or tree plantation. In Montréal, you can also use it in your flower beds.

Boroughs regularly distribute compost, usually during the spring and fall seasons.

Educational component

The building is equipped with a glass observatory, complete with a digital immersive experience for visitors to enjoy. The centre also has an education room, where visitors can learn about waste materials. It will be open to the public as of 2025.

A work of public art integrated in the treatment centre for organic waste
