• Homegrown energy

    Producing more energy means importing less of it. By transforming their organic waste locally, municipalities reduce their dependence on fossil fuels. It’s one step closer to energy independence.
  • Potential that has promise

    Biomethanation gives your table scraps a second life and reduces the amount of waste that ends up in landfills. The energy produced by municipalities can be used to power their buildings and vehicles.
  • A sustainable solution

    In addition to possessing all the properties of ordinary natural gas, biomethane is a renewable and carbon-neutral energy source that emits 90% less greenhouse gas than oil. A smart choice for transportation and heating.

This is how biomethane is produced:

  1. You save your table scraps
  2. They’re collected
  3. The plant transforms them into biomethane
  4. Biomethane is added to the gas network
  5. The energy is ready for use


Mini biomethanation glossary
Raw natural gas essentially consisting of methane (CH4) and carbon dioxide (CO2) produced from organic waste. Still contains too many impurities to be referred to as biomethane.
Refined biogas with characteristics similar to those of natural gas, but unlike the latter, is a renewable energy source.
Natural gas produced from household and agricultural organic waste. Also known as biomethane.
Compostable by-product of biomethanation. Can be used as agricultural fertilizer.
Enormous vat in which organic waste undergoes fermentation during the biomethanation process. It’s like a large artificial stomach.

Saint-Hyacinthe, biomethane producer

Innovation fueled by gas

Saint-Hyacinthe is the first city in Québec to use biomethanation to help meet its energy needs. In partnership with Énergir, this initiative will heat municipal buildings and fuel city vehicles while reducing greenhouse gas emissions. It’s a great example of a community repurposing waste to produce renewable energy.

Biomethane: a promising energy source for municipalities

By transforming them into biomethane, a 100% renewable natural gas, many Québec municipalities can reduce their energy costs and cut their greenhouse gas (GHG) emissions at the same time.
