SUEZ
Milhac-d'Auberoche
In early November 2022, SUEZ and Waga Energy successfully started up a new biomethane production unit at the Madaillan Non-Hazardous Waste Storage Facility (ISDND) in Milhac-d'Auberoche, located in the Dordogne region of France. This new installation marks the fifth biomethane production unit jointly commissioned by SUEZ and Waga Energy, further strengthening their partnership in advancing sustainable energy solutions. The facility will harness the potential of organic waste to generate renewable energy, contributing significantly to reducing greenhouse gas emissions and supporting the transition to a circular economy. This milestone not only underscores the commitment of both companies to innovation and sustainability but also plays a crucial role in France's broader goals of increasing renewable energy production and decarbonizing the waste management sector.
SUEZ will produce up to 20 GWh/year of biomethane, ie. the annual consumption of 3,000+ households in the Greater Périgueux area, avoiding the emission of 3,500 tons of CO2e per year, by replacing fossil natural gas
The result of ten years of R&D at Air Liquide and Waga Energy, the WAGABOX® is a breakthrough landfill gas upgrading technology. It combines two upgrading processes: membrane filtration and cryogenic distillation. Membrane filtration removes the carbon dioxide (CO2) and impurities from landfill gas. The gas is then cryogenically cooled to separate the methane (CH4) from the oxygen (O2) and nitrogen (N2). WAGABOX® technology guarantees grid compliant biomethane regardless of air concentration in landfill gas. It adapts to raw gas flow rates and composition variations and delivers three times more energy than CHP, the most approaching competing technology. Biomethane can be transported and stored using existing gas infrastructure. The solution is fully integrated and is protected worldwide by six patent families.
