Waga secures second landfill gas-to-RNG contract in Quebec

Waga Energy has secured a contract with Brome-Missiquoi Intermunicipal Waste Management Board (RIGMRBM) to produce biomethane (renewable natural gas) at a landfill in Québec.

This is the second contract in Canada for Waga Energy, which was selected earlier this year by Enercycle to equip the Saint-Étienne-des-Grès landfill.

Waga Energy will build a WAGABOX® purification unit on-site at Cowansville landfill to transform the gas into biomethane, which will then be injected directly into Énergir’s gas grid. Until now, the gas produced by the landfill waste was flared to prevent direct emissions of methane into the atmosphere. The WAGABOX unit in Cowansville will be commissioned at the start of 2023.

Cowansville landfill treats 75,000 tonnes of waste annually. Designed to recover 1,000 cubic metres per hour of gas, the WAGABOX unit will produce 30 GWh of biomethane per year and supply 1,750 Quebec households with renewable gas, thereby avoiding the 5,000 tonnes of CO2 emissions per year.

This project will contribute to the Quebec Government’s objective of increasing the share of green gas into networks by 10% by 2030.

“Several experts were consulted to ensure that we had the best technology for our site,” said David Rumsby, managing director of RIGMRBM.

“After a comprehensive due diligence was carried out, our choice fell on the company that offered the best technology and, above all, had the most positive impact on the environment.”

Waga Energy will finance the construction of the unit, as well as the connection of the installation to the gas network, 5 kilometres away. It will also purchase the RNG produced on-site from RIGMRBM for 20 years, as well as operate and maintain the unit and generate income by selling the green gas to a Canadian energy company.

The WAGABOX unit will be built by Waga Energy’s Canadian subsidiary, with the support of local subcontractors. Only the cryogenic distillation module, which concentrates a large part of the firm’s unique expertise, will be manufactured in France and shipped overseas.

Mathieu Lefebrve, CEO and co-founder of Waga Energy, commented: “We are happy to be able to help the RIGMRBM to improve its environmental practices through our innovative gas recovery technology.

“This new contract in Quebec is the result of the significant work we committed over the past two years to deploy our solution in North America and help move the energy transition forward. Our investor-operator model involves a long-term commitment and required the establishment of local industrial capacities to build and operate our units.”

Waga Energy already operates 10 WAGABOX units in France, representing a production capacity of 225 GWh of biomethane per year.

With six new units under construction, including high-capacity units, the company plans to increase production ‘significantly’ over the next 18 months.
