Hazardous household waste (HHW) includes a large number of commonly used products. Although they represent only 1% of the waste produced by Quebec households, they contribute significantly to the toxicity of a landfill site if they are disposed of in household garbage. As well, the dumping of hazardous waste in sewers can have serious consequences for the environment.
Anything generated in the home that is corrosive, flammable, toxic, explosive, oxidizing or leachable (mostly called solvents) constitutes HHW.
HHW represents a physical hazard (explosion), a health hazard and/or an environmental hazard if not properly disposed of and treated. Therefore, they must be handled, stored, and transported with care while being disposed of safely.
Other characteristics may also be associated with HHW that warrant special management. Some products, such as computer equipment or batteries, contain several chemicals and heavy metals (mercury, lead, chromium, cadmium, etc.) that can lead to soil contamination and water pollution.
Did you know? One litre of oil can contaminate one million litres of water.
How to recognize HHW?
Ask yourself these two questions: Would I put this product on my skin? Would I put this product in my mouth? If you answer "No" to either of these two questions, the product should be considered as HHW.
HHW can usually be recognized by pictogram(s) found on the product label. HHW most often comes in liquid, viscous, paste, gas or powder form.
The presence of symbols may help to identify some HHW:
All HHW does not include such symbols, for example, paint, oil, batteries, compact fluorescent lights, car batteries, and medications, are often packaged without warnings on labels. HHW is also not always stored in its original container (old cans or containers).
How to safely store your HHW?
HHW should be stored in leak-proof containers, out of the reach of children and animals.
Avoid pouring or mixing products; this can cause dangerous chemical reactions and/or produce toxic gases (in addition to reducing the possibility of reuse, recycling or energy recovery of materials).
The accumulation of HHW should be avoided; its presence is a common cause of fire and can be a health hazard.
What to do with HHW?
It is important to never dispose of HHW in your household garbage, in the sewer system or more broadly in nature. HHW also has no place in the regular collection of recyclable materials.
HHW must be deposited at appropriate and designated disposal sites. Once recovered from these locations, HHW is sent to specialized industries for processing and recycling.
You can return your HHW at mobile collection sites offered free of charge to all citizens of the MRC.
The MRC du Haut-Saint-Laurent collects HHW during mobile collections at temporary sites according to a set schedule. The collection of HHW is accessible to residents of the 13 municipalities within the territory of the MRC. Only household products are accepted. Others – such as agricultural, industrial and/or commercial waste – will not be accepted.
In 2023, collections will take place from 8:30 a.m. to 4:00 p.m. at the following dates and sites:
Saturday, June 10: 5001 Route 132, Saint-Anicet (Municipal Garage)
Saturday, July 8: 1539, chemin de Fertile Creek, Très-Saint-Sacrement (Municipal Garage)
Saturday, August 12: 1570 Route 202, Franklin (Municipal Garage)
Saturday, September 16: 9 St. Paul Street, Ormstown (Ecocentre)
The list of accepted HWW and products as well as the collections guidelines will follow in the next sections.
Some types of HHW can be returned to a municipal depot/town hall, pharmacy or retailer.
Did you know? Smoke detectors are safe to be thrown in the garbage (recommended by the Ministry of the Environment because of their low radioactivity per unit), as can light bulbs (incandescent).

Mobile Collections Instructions and Guidelines
Instructions for disposing of HHW at collections:
Bring your HHW in the original container, otherwise in identified sealed containers.
Report any product where the origin is unknown to collection staff on site.
No decanting will be permitted at the collection site.
Deposit HHW, at scheduled times only, as this waste is toxic and accidents could occur if it is left unattended.
In order to facilitate the recovery and processing of HHW, identify your products well, with the original label if possible.
How can we reduce the use of hazardous household products?
Our consumption habits directly influence the amount of HHW we generate. We can contribute to the sound management of HHW through source reduction or waste prevention and through the reuse of products.
Here are a few tips to reduce the amount of HHW in circulation:
Avoid buying products identified with a hazard symbol.
Replace toxic cleaning products with natural/organic alternatives (no toxic fumes) or homemade recipes .
Ask your retailers for information.
Buy a product in the format strictly corresponding to the necessary quantity.
Buy recycled paint (e.g. Boomerang). Use rechargeable batteries instead of single-use batteries.
Offer your surplus paint and other products (e.g. antifreeze).
 Example of basic ingredients: vinegar, soda crystals, borax, baking soda, white soaps.
