April 13, 2021. Waga Energy, the Mauricie Residual Materials Management Board (RGMRM) and Énergir are joining forces to launch a renewable natural gas (RNG) injection project at the Saint-Étienne-des-Grés landfill site, the first project of its kind on Canadian soil. The WAGABOX® technology that will be used for this project allows landfill site operators to recover the gas emanating from these sites in the form RNG, also known as biomethane.
As part of this project, Waga Energy is committing to purchasing the gas produced by waste products from the RGMRM for a twenty-year period. To recover it, Waga Energy will build a treatment unit on the site, using its WAGABOX® patented technology. Waga Energy will fund the unit’s construction and operation, as well as the costs of connecting the site to the local gas network. Énergir will purchase RNG production from Waga Energy, thus contributing to achieving the Quebec government’s objective of introducing a 10% share of renewable gas into the network by 2030.
Given that Saint-Étienne-des-Grès is the largest community-managed landfill site in Quebec, RGMRM will become the first North American waste treatment operator to benefit from the WAGABOX® solution, which combines breakthrough technology and an investor-operator model. This site receives 180,000 tons of waste each year.
The WAGABOX® unit in Saint-Étienne-des-Grès, which will be built in Quebec by the Canadian subsidiary of Waga Energy and will be operational as of 2022, will be able to treat up to 3,400 cubic meters of gas and produce 468,000 gigajoules of RNG per year, which is the equivalent to the annual consumption of 8,000 Quebec households. Its operationalization will prevent 23,000 tones of CO2e emissions each year.
