In Canada, Régie des matières résiduelles du Lac-Saint-Jean (RMR), owner, and operator of the Hébertville-Station landfill serving 50 municipalities in the Saguenay-Lac-Saint-Jean region and the Mashteuiatsh community in Québec and Waga Energy Canada, a subsidiary of France-headed landfill gas (LFG) to renewable natural gas (RNG) technology provider Waga Energy SA, have signed an agreement to produce RNG at the Hébertville-Station Landfill site in the Saguenay-Lac-Saint-Jean region.
The Hébertville-Station landfill site has an annual capacity of 203,500 tonnes of waste. The decomposition of organic materials within this waste generates landfill gas (LFG), which is currently captured and flared.
As part of the project, Waga Energy will construct and operate a purification unit, using its patented WAGABOX technology, to convert LFG into RNG, a renewable substitute for fossil-based natural gas.
Once the WAGABOX unit is operational in 2026, the gas will instead be purified and injected into Énergir’s natural gas distribution network to supply renewable energy to local residents and businesses.
The facility is expected to produce up to 55 GWh of RNG per year (188, 000 MMBtu) —enough to meet the energy needs of approximately 2,280 households.
Aligned with provincial goals
The feasibility study for the project received CA$300,000 in funding from Québec’s Ministry of Economy, Innovation, and Energy, under the Renewable Natural Gas Production Support Program, and is financed by the Electrification and Climate Change Fund.
This special fund supports measures under the 2030 Green Economy Plan to combat climate change. Additional funding applications for the necessary investments will also be submitted under this program.
This initiative aligns with Québec’s goal, outlined in the 2030 Green Economy Plan (PEV), to integrate 10 percent RNG into the gas network by 2030.
The collaboration between Waga Energy and the RMR represents a concrete contribution to this objective.
By avoiding the release of roughly 10,000 tonnes of carbon dioxide equivalents (CO2eq) annually, the project will help reduce the region’s carbon footprint and advance Québec’s climate goals.
With this innovative project, the RMR is taking a decisive step toward maximizing the value of residual waste. By capturing and transforming landfill gas into renewable natural gas, we are directly contributing to Québec’s climate goals while providing a clean energy source. This partnership with Waga Energy reflects our vision of resource management focused on the future and is beneficial for our region, said Luc Simard, President of the RMR and Prefect of the Maria-Chapdelaine RCM.
Fifth Waga Energy project in Canada
This is Waga Energy’s fifth biomethane project in Canada. Three units are already operational in Québec, in Saint-Étienne-des-Grès, Cowansville, and Chicoutimi respectively, with another under construction in British Columbia (BC).
I’m thrilled about this collaboration with the RMR Lac-Saint-Jean. Together, we are working toward a more responsible management of landfill gas at the regional landfill of the Saguenay-Lac-Saint-Jean region. We commend the dedication of the RMR’s elected officials and teams to the energy transition, a core driver of Waga Energy’s growth. Our teams have already demonstrated their expertise with three projects in Québec and the ongoing construction in British Columbia. This new project reaffirms the attractiveness of our WAGABOX technology and our commitment to supporting landfill operators in their transition efforts, remarked Julie Flynn, CEO of Waga Energy Canada,
