Waga Energy, the Europe-based leader in landfill gas-to- renewable natural gas (RNG) technology, has been appointed by The Mauricie Residual Materials Management Board (RGMRM) to exploit its innovative gas upgrading solution at the Saint-Étienne-des-Grès landfill in Quebec. Énergir, the comprehensive gas distribution company in the province, will purchase the produced green gas and inject into its gas grid onsite. The landfill gas-to-RNG project will be the first in Canada to employ the WAGABOX® technology, built by Waga Energy, to recover landfill gas in the form of RNG.

Following the agreement signed in March, Waga Energy will purchase the landfill gas from RGMRM for a duration of at least 20 years. Then the landfill gas will be transformed into grid-compliant RNG by a WAGABOX® gas treatment unit built onsite. Waga Energy will make income by selling its RNG production to Énergir. Til now, the landfill gas at Saint-Étienne-des-Grès was captured and burned in a flare.

The WAGABOX® unit in Saint-Étienne-des-Grès is designed to process 3,400 cubic meters of biogas per hour (2,000 scfm), expected to produce 468,000 GJ (444,000 mmBtus) of renewable gas per year, corresponding to the yearly consumption of 8,000 local households. A local company will develop the WAGABOX® unit under Waga Energy’s Canadian subsidiary’s supervision. But there is an exception, as the cryogenic distillation module will be imported from France. The project is foreseen to be completed by 2022. 

The project will develop the environmental record of Mauricie and will contribute to Quebec’s energy transition. It will obstruct the release of 23,000 tons of CO2 per year into the environment by substituting renewable gas for fossil natural gas.

President and Co-Founder at Waga Energy, Mathieu Lefebvre showed gratitude towards the WAGABOX® solution. He stated that because of this project, hundreds of landfill sites across the United States and Canada will be able to generate renewable natural gas, contribute to the energy transition, and generate a new revenue stream, without any investment, and free from additional operating constraints.

Michel Angers, President of RGMRM, stated that this contract is the result of an initiative undertaken several months ago to recognize the best technology to enable them to use landfill gas to its full potential. He acknowledged the WAGABOX® technology and said that treating their gas is no longer an expense. It is a new income source, and more importantly, it is yet another step towards a more sustainable approach to landfill management. The project fits correctly with the government’s greenhouse gas reduction objectives, and they are proud to contribute to Quebec’s energy transition.

Renault Lortie, Vice-President of Customers and Gas Supply at Énergir, stated that the development of the green gas industry in Quebec is one of the cornerstones of their efforts to decarbonize the economy. Énergir intends to inject an ever-increasing amount of renewable gas into its network, equivalent to a volume of at least 10% that of an yearly volume it distributes by 2030. This fantastic project brings them a step closer to this objective, demonstrates the value of a smart circular economy, and enables more and more of their customers to benefit from clean and local energy.

WAGABOX® is a breakthrough technology for the restoration of landfill gas in the form of RNG injected into gas grids. This innovative technology resulted from 10 years of research & development and benefitted from French industry giant Air Liquide’s active support. Combining membrane filtration and cryogenic distillation, it ensures a higher energy yield than solutions based on electricity production, and the best use of the resource, without operational constraints for the landfill operator.
