Organic Waste

Organic Waste Collection (green waste + food scraps)

Almost half of the waste materials produced by the residential sector consist of organic waste. When disposed of with household garbage, this waste ends up in landfill (waste disposal) sites and slowly decomposes, releasing biogases in so doing and contributing to climate change.

Collection is required for all buildings served.

Time of day and location

Organic waste may be disposed of by the curb between 7 p.m. the day before and 7 a.m. on the day of the collection.

Containers

Brown bins used for this collection are provided by the City when the collection is first implemented. These bins remain City property and may not be used for other purposes. They belong to the address delivered and must remain on site at moving time. Excess food waste may be disposed of next to the brown bin, in a paper bag, a cardboard box or garbage can.

PLEASE NOTE: PLASTIC BAGS ARE PROHIBITED!

NO plastic bags, including those that are certified biodegradable or compostable—are accepted for this collection.

Why not?

The composting site where the Borough of Lachine sends the organic waste that it collects does not have the certification required to open plastic bags. TheMinistère du Développement durable, de l’Environnement et de la Lutte aux changements climatiques issues this certificate only to centres that prove they have met their requirements relating to controlling the gases that may be produced inside these bags. The Ministère takes the view that all plastic bags, whether biodegradable, oxo-biodegradable or compostable, cause anaerobic decomposition conditions that produce biogases in turn.

Moreover, plastic bags, including those that are certified biodegradable and compostable, take more time to decompose than the composting process for organic materials in itself. As a result, even after processing, pieces of plastic are found in the compost.

Tips and advice

Summer

  • Take out the bin every week, even if it isn't full.
  • Keep your bin in the shade.
  • Wrap the materials in newspaper or paper bags, especially meat or fish, and put some newspaper on the bottom of the bin to absorb excess liquid.
  • Sprinkle a little baking soda or place a charcoal briquette in the bin.
  • Rinse the bin with a solution of vinegar and water.
  • Freeze or refrigerate delicate foods and place them in the bin on the day of the collection.
  • If white grubs appear, sprinkle them with vinegar or salt.
  • To keep squirrels away from the brown bin, coat the lid with cough ointment (available over the counter in pharmacies and supermarkets).

Winter
In winter, to prevent your brown bin from freezing and becoming difficult—or even impossible—to be emptied by our crews:

  • Place layers of newspaper at the bottom of the bin and bag. The paper will serve as insulation and make it easier to absorb the excess moisture from the food.
  • If you don't use any bags, coat the inside of the bin with a bit of vegetable oil so that the waste doesn't stick to the walls of the bin, in case of freezing temperatures.
  • Please take care not to interfere with snow clearance operations when placing your bin by the curb for collection.

 Composting centre

Organic waste collected on Lachine territory is transported to an open-area composting site (Mironor in Brownsburg-Chatham). High-quality compost is produced there for use in agriculture and landscaping.

Ville de Montréal's composting centre, scheduled to open in 2020 in the Borough of Saint-Laurent, will be accepting organic waste from Lachine territory. The nearness of this centre will reduce the distances to be covered by approximately 80%.
