The budget for 2025 is exhausted! Thank you for your interest and participation. See you next year!

Would you like to save up to $100 on the purchase of a home composter?

The home composter produces fertilizer for use in the garden. It’s an environmentally-friendly way to dispose of organic materials such as dead leaves and fruit and vegetable residues.

The City reimburses 50% of the cost of purchasing a new backyard composter, up to a maximum of :

  • 100 for a composter purchased from a Brossard business
  • 75 for a composter purchased from a business outside Brossard

Eligibility criteria

  • Be a resident of the City of Brossard;
  • Apply no later than 12 months after the date of purchase.
  • A limit of one subsidized composter per residential address will apply.
  • Electronic composters are not eligible.

Documents to be prepared

  • Proof of residence (e.g. driver’s license, electricity bill, municipal tax bill)
  • Proof of purchase
    • The following items must appear on the invoice:
      • Date of purchase
      • Dealer name and contact details
      • List of purchased items
      • Total cost

Fill in the form

The subsidy programs are now closed for 2025, as the budget has been exhausted.


Frequently asked questions

Composting is a natural recycling process. In the presence of oxygen, micro-organisms, insects and worms transform organic matter into a product rich in humic compounds: compost. The effective use of a home composter allows you to :

  • Divert nearly 40% of your waste from landfill;
  • Reduce the production of greenhouse gases associated with the landfilling and transportation of residual materials;
  • Reduce groundwater contamination.

Since 2017, Ville de Brossard has gradually implemented food waste collection throughout its territory. This project is part of the government’s drive to ban organic matter from landfill sites.

Additional resources

Ideally, choose a well-drained, semi-shaded spot where you can add water if necessary. If it lacks moisture, biological activity will slow down.

The City’s brown bin is collected by a contractor and you can drop off your animal waste. The home composter is installed in your garden, where micro-organisms transform your organic matter into compost that you can reclaim.
