Composting

FOOD IS NOT GARBAGE!

The Green Bin program is a very effective way to reduce the amount of material going to landfill and prevent the loss of a valuable resource: food waste.

THANK YOU FOR YOUR EFFORTS!

Since the implementation of food waste collection in 2009, thousands of metric tons have been diverted from landfills. In 2018 alone, nearly 560 tons of food waste were collected by the City.

DID YOU KNOW?

Food waste represents about 25% of the contents of a garbage bag

Burial of food waste contributes to groundwater contamination and to the production of methane, a greenhouse gas 25 times more powerful than CO2

In addition to being polluting, landfilling is expensive for cities and taxpayers

The Quebec Residual Materials Management Policy aims to prohibit organic materials in landfills.

Composting is the process of biological digestion of organic matter. It results from the action of microorganisms breaking down organic matter, such as food residues, in the presence of oxygen. This produces a soil rich in fertilizing compounds: compost.

CURBSIDE COLLECTION OF COMPOSTABLE MATERIALS

SINGLE-FAMILY HOMES AND SMALL APARTMENT BUILDINGS

In May 2009, Westmount finished implementing a weekly curbside collection of compostable kitchen waste for single-family homes and small apartment buildings.

STEP 1

Keep your green bin clean and dry by placing a few sheets of newspaper or paper towels at the bottom.

STEP 2

Add a compostable plastic or paper bag inside the bin.

STEP 3

Wrap your food waste in newspaper or place it directly in your green bin.

SINGLE-FAMILY MULTI-RESIDENTIAL BUILDINGS OF 9 UNITS AND MORE

In 2018, the City of Westmount expanded its composting program to buildings with 9 or more units. The buildings participating in the program have their 2nd weekly garbage collection replaced by a compost collection.

Phase 1 of the expansion program began in July 2018 and involved 20 buildings with a maximum capacity of 70 units located south of De Maisonneuve between Clarke Avenue and Lansdowne Avenue.

Phase 2 of the composting program began in October 2019 and targets buildings between 9 and 30 housing units across the territory.

STEP 1

Add a compostable plastic or paper bag inside your kitchen counter bin.

STEP 2

Wrap your food waste in newspaper or place it directly in your bin.

STEP 3

Tie the bag or fold down the newspaper and transfer the contents into your building’s green bin.

To obtain a new bin, or replace a broken or damaged bin, please go to the Westmount Recreation Centre at 4675 St. Catherine Street West, during regular business hours (please bring a proof of residence). Please note that the green bin is the property of the City of Westmount and should be left at the home when you move.

TIPS AND TRICKS

To line your bin, use:

  • Absorbent paper or paper bags
  • Newspaper, leaflets or cardboard boxes
  • Paper food waste bags
  • Certified 100% compostable plastic bags with one of the following certification logos

Organic materials are mainly composed of water. The most important thing to do to avoid odors is to reduce humidity:

  • Wrap your residues in newspaper or cardboard
  • Double your bin
  • Alternate wet materials (table scraps) and dry materials (paper towels, tissues, etc.)
  • Do not pour any liquids in your bin
  • Keep your food waste in the refrigerator or freezer the until the collection
  • Put out your bin for collection every week, regardless of the amount of waste collected
  • Sprinkle baking soda or salt onto your food residues
  • Hang your bin 18 inches from the ground
  • Keep the bin in a shelter or inside until collection day
  • Apply a mentholated ointment around the opening of your bin
  • Eliminate white grubs by pouring salt or vinegar on them
  • Wash your bin with water and a mild detergent
  • Sprinkle baking soda in the bottom of your bin
  • Kitchen counter bins can be put in the dishwasher

Organic materials are materials that are biodegradable by microorganisms, and therefore compostable. These include food waste, yard waste and other types of waste from industrial and municipal activities.

Table scraps and yard waste are transported and processed in two separate composting centers, so it is important not to mix them. Yard waste, such as plants, lawn clippings, small branches and leaves are collected by a separate collection by City teams. For more details, see the garden waste page here.

Food waste is transported to the Recyclage Notre-Dame composting center where it is mixed with wood chips and placed in swaths. As organic waste degrades, it produces heat. The internal temperature of the swath increases to 70°C, which eliminates pathogens. The composting process takes about six months and the finished product is used as soil fertilizer. Since the residues brought in are minimally sorted, it should be noted that it is very important that the green bin only contains compostable materials.

Due to health and safety concerns for employees who pick up materials, waste placed in the green bin must be packaged in newspaper, paper bag, or compostable plastic bags. It is important not to deposit bulk residues in the bin, as this may create odor and cleanliness problems.

Organic matter is composed mainly of water. In the presence of liquids, anaerobic decomposition of the materials occurs, which can cause odors. The essential thing to do to avoid odors is to limit the humidity in the bin. Wrapping the residues in newspaper before putting them in the green bin is the best solution. You can also store leftovers in the freezer or refrigerator and put them in your bin the day before the collection, especially during hot weather periods.

Participation in the composting program is not mandatory, but is strongly recommended. Collection programs such as the Green Bin and Blue Bin divert waste from landfills and demonstrate the contribution of residents to the health of their city. In addition, the Government of Quebec aims to ban organic materials from landfills within a few years to reduce the amount of waste landfilled.

If you have a composting unit at home, it is not necessary to stop using it. Residents are encouraged to use the green bin for materials that should not be added to the household composter such as meat, fish and dairy products.
