Do we need to rinse containers before putting them in the recycling bin?

It is recommended to rinse containers to avoid contaminating the residual materials and to protect the health of the employees involved in the recovery, sorting and recycling stages. You are also preventing bad odors in your recycling bin!

How can we help solve the problem with residual materials?

Opt for the 4Rs! Before even making a purchase, take a minute to think about reducing at source or how the product will be reused. When the object is no longer useful, put in the recycling bin. You can also make sure objects have a valuation by donating them or ensuring they will be reused. Even our waste is reused when put in an engineered landfill site since renewable energy is produced from the biogas generated during the decomposition process!

Do we have to remove labels on cans?

It is recommended to remove labels in order for the paper to be recycled same as the metal of the cans. During the recycling stage, the containers are melted at high temperature and the paper is burned. Therefore it does not affect the transformation of the metal.

What is the difference between a sanitary landfill site and an engineered landfill site?

An engineered landfill site (ELS) is designed to limit the risk of pollution and the impact on the environment as much as possible. In general, we will be able to prevent the release of leachate from the containment cells, to capture the biogas produced through waste decomposing and even often to produce renewable energy from biogas.

What is a waste materials management plan (WMMP)?

A waste materials management plan is the document that lays out how a municipality, an institution or a business will manage the residual, recyclable and putrescible materials generated on its territory. For municipalities it is a legal requirement, but many businesses now consider it to be a social responsibility to minimize its environmental impact with a sound management of its residual materials.

Do you recycle everything?

Selective collection recycles the following items to carry them at our sorting centre:

  • Tin cans
  • Aluminium
  • Ferrous metal
  • Milk and juice containers
  • Plastics (code #1 to #7, excluding #6)
  • Flexible plastic films)
  • Bottles & containers
  • Paper (newspapers, magazines, flyers, office paper, envelopes, etc)
  • Cardboard (flat and corrugated
  • Small household appliances (toaster, oven, etc)
  • Frying pan, kettle


What happens to the content of my bin after it has been picked up by the recycling service?

Your blue bin’s content is brought to a sorting centre after having been emptied in our selective collection truck. The materials are mechanically separated under the watchful eye of our employees, and then crushed and bailed to be taken to the appropriate recycling plant. Non-recyclable materials rejected during the sorting process are taken to the landfill site.

What is the difference between the different recycling bins?

A small green bin is better for dwellings and apartments, even though their residents usually should empty their little bins in the big rolling bin. It is the latter that will be emptied when the recyclable waste is collected, with the help of a mechanical arm, in most of the municipalities we serve. This collection method limits greenhouse gas emissions since trucks spend less time idling in the streets.

What is the difference between the different types of containers?

First, there is the volume the bin can hold – this will have an impact on how often it will be lifted. Front loading containers are generally used for the smallest of volumes, and trucks must be able to get to them in order to lift and empty them. “Roll-off” bins are used for larger volumes – they are picked up by a truck, placed on a trailer and then taken to the landfill site or the transfer centre. Compacting-type bins reduce their own content, and they will also be picked up by a truck to be emptied. Last, but no least, semi-underground containers offer a more discreet look since only a part of them appear above the ground.

What is dry material?

“Dry material” is construction, renovation and demolition waste – usually building materials that are no longer useful, such as used roof shingles. Once they are recovered, these materials will become parts of new objects.

What does “life cycle analysis” mean?

Life cycle analysis (LCA) is a method used to determine an object’s real environmental footprint; from the moment it was made to the end of its useful life. The method helps find ways to evaluate how an object could generate less residual materials – with its packaging is an example.

What will the recycled items are used for?

Paper and cardboard become paper and cardboard again, but of better quality. Plastic containers are recycled into polar fleece clothing, packaging or containers or other useful products. Aluminum cans are completely recycled, without any loss in quality. Glass bottles and containers are used to make other containers, fibreglass insulating material, abrasive material or filtration products.

Can I bring old tires or waste oil to an ecocentre?

Services Matrec’s ecocentres accept this type of material, but we recommend you get more information beforehand by visiting our page on ecocentres.
