Organic waste like table scraps is converted into biomethane, an entirely renewable gas, which is then used to fuel vehicles or heat buildings. And there you have it—an endless cycle of renewable energy.

This project is garbage!

The city of Saint-Hyacinthe received support from Gaz Métro to build Québec’s first biomethane plant. In 2017, it will also be the first municipality to heat its buildings and operate its vehicles with renewable natural gas.


Thanks to a project carried out in cooperation with G4 Insights, wood chips we turned into renewable natural gas. Tests showed that the process is technologically exploitable; a larger pilot project is in preparation.

How do you like them apples?

If 266 apple cores pull together, they can fuel a tractor-trailer for one kilometre. How? By transforming into biomethane, a process that produces 90% less greenhouse gas emissions than oil.


Cow patties can also be turned into biomethane. Vermont’s Blue Spruce Dairy Farm gives cow dung a second life by transforming it into renewable energy. Gaz Métro is proud of its investment in Green Mountain Power, who then distributes the electricity produced with it. And that’s a smart moo-ove!

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.


By 2022, Québec municipalities will no longer be allowed to dispose of household waste in landfills. Instead, they can either turn it into compost or convert it into biomethane. As a result, local production of renewable natural gas will skyrocket. No fewer than 60 municipalities will soon be following in Saint-Hyacinthe’s footsteps by carrying out their own methanation projects. A small step for our household waste, but a giant leap for Québec’s energy future.
