About biomethanation

  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.

How to produce renewable natural gas

Biomethanation gives your table scraps and other organic residues a second life, which reduces the amount of waste that ends up in landfills. The biomethane produced from this matter can be added to our gas network to heat buildings, fuel vehicle fleets, and much more.

Saint-Hyacinthe, biomethane producer

Saint-Hyacinthe was the first city in Québec to produce energy through biomethanation and move one step closer to energy independence. Implemented in partnership with Gaz Métro, this initiative will heat municipal buildings and fuel city vehicles while reducing greenhouse gas emissions. This project will, in time, lead to an annual reduction of 25,000 tonnes of greenhouse gas. It’s a great example of a community repurposing waste to produce renewable energy.

Cattle manure: another way to produce biomethane

Cattle manure is organic matter that can also produce biomethane. Fully transferable in the form of natural gas, the biomethane produced from cattle manure can be injected into the gas network or used to produce electricity.

This is what’s happening in Vermont, where our subsidiary Green Mountain Power buys electricity produced from cattle manure from the Blue Spring dairy farm. This family-run business is a pioneer in the field — it’s been converting cow manure into energy since 2005!

Other forms of natural gas

There are several forms of natural gas, allowing citizens to consume better and less. Renewable to give our waste a second life, compressed or liquefied to replace diesel as a fuel, natural gas is an energy that meets a variety of needs.

  • Natural gas

    Gaz Métro is the largest gas distributor in Québec and Vermont.
  • Liquefied natural gas

    LNG is natural gas that changes from a gaseous to a liquid state.
  • Compressed natural gas

    CNG is compressed natural gas that can be used as fuel.

Gaz Métro, more than natural gas!

We believe diversity is key to the future of energy. This is why Gaz Métro is involved in developing solar and wind power and hydroelectricity.
