What if our table scraps could be used to heat our homes?

Organic waste makes an incredible raw material for producing renewable natural gas (RNG).

Now, all our customers can have access 

to renewable natural gas (RNG)

How is renewable natural gas produced?

Biomethanation

Organic waste is collected and transported to a biomethanation plant where it is converted into energy, i.e. renewable natural gas (RNG).

Injection into the network

RNG is injected into the traditional natural gas network. Renewable and traditional natural gas molecules intermingle and are interchangeable.

Purchasing RNG

By purchasing RNG, you reduce greenhouse gas emissions (GHGs) in Quebec and help drive the development of the RNG sector. Although we can’t guarantee that RNG is supplying your home, a portion of the RNG that flows through the network is attributed to you. And only you can claim that you are improving your carbon footprint with the purchase of this renewable energy.

Renewable natural gas: energy with a future

Reduced GHG emissions

Renewable natural gas (RNG) is a 100% renewable source of natural gas that reduces greenhouse gas (GHG) emissions in two ways: First, by replacing fossil fuel with renewable energy, and second, by diverting organic waste that produces methane emissions in landfills.

Value-added waste

Turning table scraps into RNG is easier than you think! Residual organic matter becomes a valuable energy source when transformed into RNG. In addition, the process creates an all-natural fertilizer that can be used on garden beds and farms alike.

Locally produced energy

Did you know that your municipality can produce renewable natural gas using your organic waste? Well, it turns out that it’s a very effective municipal waste management solution..

Organic waste that pays off

Waste with energy to spare: I’ll buy that! RNG production can be an opportunity for municipal governments, farmers and various industries to turn their organic waste into new revenue streams.

Shining the spotlight on RNG producers

To meet the growing demand for renewable natural gas, Énergir deals with suppliers from all over Quebec and North America.

Meet our first producer: Saint-Hyacinthe

Saint-Hyacinthe was the first city in Quebec to produce energy through biomethanation and move one step closer to energy independence. Implemented in partnership with Énergir, 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 tons of greenhouse gas. It's a great example of a community repurposing waste to produce renewable energy.



Coop Agri-Energy Warwick

Coop Agri-Énergie Warwick is the first agricultural cooperative dedicated to renewable energy production in Quebec. Since the spring of 2021, it has brought together a dozen agricultural producers from the Arthabaska MRC who produce RNG from slurry and dairy cattle manure mixed with residual organic matter from local businesses. The biomethanation facilities were developed, built and are now run by Coop Carbone, a non-profit cooperative solidarity that develops cooperative agricultural biogas projects.


Quebec

Starting in 2023, the City of Québec will be injecting renewable natural gas into Énergir's network. The Quebec Agglomeration Biomethanation Center (CBAQ) is currently under construction. The plant will treat:

  • food residues (86,600 tons/year)
  • biosolids (a product of the wastewater treatment plant) (96,000 tonnes/year).

Why is renewable natural gas considered clean?

Through a process of biomethanation, organic matter (food waste, slurry, manure, wastewater, etc.) is transformed into biogas, which once purified becomes renewable natural gas. 

This product reduces greenhouse gas emissions in two ways: first, by replacing fossil energy with renewable energy, and second, by avoiding methane emissions associated with the disposal of organic waste at landfill sites. 

Renewable natural gas is recognized by Natural Resources Canada as a renewable energy and clean fuel that will help Canada achieve its new net-zero emission targets. In addition, according to the Government of Québec’s Regulation respecting mandatory reporting of certain emissions of contaminants into the atmosphere, greenhouse gas emissions for RNG are very low and comparable to hydroelectricity emissions (0.30 kg CO2-eq/GJ for RNG vs. 0.44 kg CO2-eq/GJ for hydro).

Can natural gas really be renewable?

Yes, if it is produced from a renewable source. There are five main sources of renewable energy: the sun, the earth (geothermal energy), wind, water and organic matter. In the case of RNG, the raw material is residual organic matter. Be it table scraps, wastewater, slurry or farm manure, these materials all have very short renewal cycles.

How do you plan to offer RNG to customers in the coming years?

Énergir is working hard to reduce the carbon footprint of the natural gas it distributes, and it believes that RNG is one of the ways to get there. Its aim is to have RNG represent 5% of the gas injected into its existing network by 2025, replacing traditional natural gas. The cities of Saint-Hyacinthe and Québec already have production projects underway. And the province has the potential to do so much more! This is why our teams are hard at work mobilizing all actors involved in developing these promising projects throughout Quebec.

Will producing RNG encourage food waste?

Our wish is to get the full value out of every item of food. However, we are aware that no matter how much we try to reduce food waste, certain organic materials such as pits, skins and peels will never be eaten. With RNG, we want to reuse the organic materials that end up in brown bins to give them a powerful second life.

What if RNG good for?

Énergir firmly believes that making complementary use of a variety of energy sources is the most effective way to reduce greenhouse gases. As we always say, you need the right energy in the right place!

That’s why we rely on RNG as a greener energy source in cases where using electrical power would be too complicated, such as heating a large building or when a flame is required for an industrial process
