Get details about organic material collections

Last updated November 25, 2025

Collection schedules, accepted materials, materials that are not accepted and types of bins that are allowed. Find out how to put out kitchen scraps for collection and composting.

Only 5 boroughs offer an organic waste collection: Lachine, Le Plateau-Mont-Royal, L’Île-Bizard-Sainte-Geneviève, Pierrefonds-Roxboro and Saint-Laurent. 

The other 14 boroughs have two separate collections: the food waste collection and the green waste collection.

What is organic waste?

Organic waste includes food waste (table and kitchen scraps), paper and cardboard with stains from food or water and green waste (dead leaves, grass clippings and other plants).

Unfortunately, these materials are often thrown away and sent to a landfill. Landfilled organic waste generates methane, a powerful greenhouse gas that contributes to global warming.

If an organic waste collection is offered in your area, you must participate. You will help reduce waste and preserve the environment.

Restaurants and food waste 

If you manage or own a restaurant, you must hire a company specializing in the collection of food waste if the volume produced is over 720 litres per week, since the city’s collection service is limited that specific volume per week per address. 

You must also obtain a permit in order to place your food waste container on public property.
