Kitchen cone

A simple, easy way to collect compostable food scraps! Three easy steps:

  • Line the cone with newspaper.
  • Put daily food scraps in the cone.
  • Once the cone is full, remove the paper containing the waste and place the whole package in the compostable waste bin outdoors.


The cone is free for residents (proof of residence required) and available from the Public Works counter at City Hall(451 Saint-Jean Boulevard).

Tips and hints

1. Transfer container

A small container is a handy way to collect food waste and transfer it regularly to the compostable materials bin. If you do not use the kitchen cone, an ice cream container with a lid will serve the same purpose. Put it in a convenient location in your kitchen and line it with paper towel or newspaper to prevent food scraps from sticking and reduce smells.

2. Leaf and grasscycling

Leaf and grass recycling are ecological practices that involve leaving shredded fallen leaves and grass clippings on the ground after mowing so that they can break down into the soil. Leaves and grass are natural fertilizers!

3. Avoid problems

To avoid Solution
Smells 1. Keep your bin or garbage can clean

  • Wash your container with full-strength or diluted white vinegar (25 centilitres of vinegar in 1 litre of water). Spray the vinegar inside and outside the container and then rinse. It is important to let the container dry before placing waste in it.

2. Use a deodorant

  • Baking soda, white or green clay 
    Place baking soda or white or green clay in the bottom of the empty bin to absorb odours. You can also add a few drops of eucalyptus oil. After collection, remove the remaining baking soda or clay and clean the container with white vinegar to limit odours.
  • Newspaper and tea tree oil
    Place newspaper in the bottom of the container and spray it with a mix of a few drops of tea tree oil diluted in a small quantity of lukewarm water. You can also place two drops of oil directly on the paper. After collection, remove the remaining newspaper and clean the container with white vinegar to eliminate odours.

3. Other tips

  • Freeze or refrigerate meat, poultry or fish waste.
  • Let leaves and grass clippings dry before placing them in the bin so they do not emit a strong ammonia odour.
  • Keep your bin or receptacle out of the sun and put it out for every collection regardless of how full it is.
Small animals
  • Take the same precautions as with household waste.
  • Apply menthol lotion around the cover.
  • Secure the cover with a bungee cord.
Flies and maggots
  • Wrap meat, poultry and fish waste in newspaper or a paper bag before placing it in the bin. You can also refrigerate or freeze it until collection day.
  • Alternate your food scraps in the bin with dry waste (paper towels, newspaper, sawdust, wood chips, dead leaves, etc.).
  • Do not put large amounts of liquid in your bin.
  • Keep your bin out of the sun, with the cover closed, and put it out for collection every week.
  • Sprinkle hot water, salt or a blend of water and vinegar on maggots to kill them.
  • In winter, to prevent materials from sticking, place a layer of newspaper or a piece of cardboard on the bottom of the bin. You can also use a paper bag in the bin.

Damaged bins

What to do if the bin provided by the city is damaged

Take note of your serial number from the side of the bin:

Take a photo of the damaged section of the bin.  Review the images below to determine if your bin needs replacing or repairing.  Repairing a bin costs less than replacement and is better for the environment.  Repairs types include: adding a new lid, end caps to secure the lid, lid axel, wheels and or wheel axels.  Replacement of the bin is required when the bin is cracked or when the portion of the bin that supports the axels are broken.
