The term “residual materials” refers to all the material that an individual would want to dispose of, more commonly referred to as waste. However, the term residual materials is more appropriate, since it puts the emphasis on the different categories of materials that we can find in our waste:

    • – Voluminous materials, which can be reused or recycled;
      – Recyclable materials, for the sorting center;
      – Organic waste, which can be valuable for composting;
      – Ultimate waste, for landfill sites;
      – Hazardous waste, with electronic and informatic equipment which can be brought to the Eco-Centres.



You can download the guide All About Collections from the Ville-Marie borough.

For more information on the various collections (household waste, recyclable materials, bulky items, green waste) offered by the Ville-Marie borough, please visit their website.

Our main goal is to reduce our consumption. The first concrete action of the 4Rs principle is the reduction. This practice addresses the management of waste at its source. Below, you’ll find simple examples of basic reducing actions:

– Stop using plastic bags: Bring either reusable bags or a backpack.
– Stop using disposable cups: All coffee shops will serve your beverages in reusable mugs and some will even offer a discounted price.
– Stop using disposable lunch bags: Most restaurants can provide resuable containers if requested.
– Stop unsolicited flyers: You can put a sticker that says you do not want to receive flyers. These stickers are available for free at the Éco-quartier Peter-McGill.
– Stop receiving the yellow pages: To stop receiving the Yellow Pages directory, click on this link and remove your address from the list.
– Stop using disposable diapers: The new reusable diapers are easy to use, eco-friendly and less expensive than disposable diapers.

To reuse something is to keep a product until it is no longer functioning, or until it can no longer be given another utility. By adopting this practice, you can prevent the exploitation of resources that are needed to create new products. Before disposing of materials or products, ask yourself if they can be used again or could be used in another way.

If you’re looking for furniture, electronics, sport items, musical instruments, books, clothing or even construction materials, always think about reusing first.

The city of Montreal offers a directory of addresses where objects can be reused, anywhere on the island of Montreal. Check their website.

Recycling is the activity or process of extracting and reusing useful substances found in waste. It’s better to recycle an object once it has been used completely and after reusing has been considered. Whenever possible, buy items made from recycled materials, as it takes 10 times less energy to produce recycled products.


This plastic is not accepted in the collection of recyclable materials. To identify the plastic types, look for a triangle made of three arrows (Mobius strip) and you can see a number inside this symbol. Here are a few examples of items made of plastic number 6 (polystyrene/styrofoam): single use plates, bowls and utensils, mushrooms package, individual yogurt container, croissants containers (noisy and breakable). The programme Finding Number 6 helps Montrealers to bring their polystyrene articles to the LaSalle Ecocenter, located at 7272 St-Patrick Street. This articles must be clean and without any packaging, label, absorbent pad or aluminium tops.

Recovery corresponds to the transformation of a residual material in order to obtain a new material or energy (ex.: composting, grasscycling, biogas, etc.).

Composting is a natural process where organic matter is decomposed by the actions of living organisms that live in the soil (bacteria, mushrooms, insects, earthworms, etc.). This process results in compost, a rich brown soil that bring nutrients to gardens.

– Up to 45% of home waste is made from organic matter;
– The organic matter that decomposes inside landfills create greenhouse gas and pollute both groundwater and surface water;
– Compost enhances the soil quality for gardening.

– Food waste collection by the City of Montreal
First of all, you need to have access to that collection in the Peter-McGill district. If this is the case, it takes place every Thursday and your bin must be left between 5 am and 8 am on the morning of the collection. You will find more information on the areas covered by the collection, the accepted materials as well as the implementation schedule on the Ville-Marie borough website.


Which bags to use?
The bags must be labeled “compostable” and not “biodegradable”. Indeed, biodegradable bags do not work for compost collection because they require a very long period to decompose (unlike compostable bags). They can be purchased at local hardware stores or pharmacies. It is also possible to use some newspapers to make paper bags that fits in the small kitchen bin.


– Garden Compost
Traditional composting for a garden can be produced using a large wooden or plastic box called a “composter”. To buy your own wooden composter, contact us! For more information, visit the Compost Council of Canada website.

– Community Composting
The Éco-quartier Peter-McGill provides large community composters in the public area. This project allows anyone who cannot make compost at home to have access to a shareable composter that could be found in the public domain. Click here to learn more about our program!

– Vermicomposting
Vermicomposting is perfect if you live in an apartment, this process lets you create compost with green organic matter inside your home, all year long. Earthworms will digest the organic matter and transform it into rich soil. To know more about vermicomposting, read Le guide de vermicompostage.

– Compost Montréal
The company Compost Montréal provides an organic waste collection service on the Island of Montreal. The service is provided throughout of the metropolitan area, on a weekly basis. If you’re interested, please click this link : Consult Compost Montréal’s website.

Hazardous household waste, computer equipment and electronics are materials that you should not dispose with your regular household waste as they pollute landfills. This is also unsafe for those who sort waste materials, as hazardous waste contact can be dangerous.


  • Eco-Centres are sites where waste is being reused or recycled. Those centres are accessible all over the city of Montreal. To know more about eco-centres :,75371938&_dad=portal&_schema=PORTAL
