  • /

WAGABOX® by Waga Energy implemented by Veolia in Claye-Souilly (France) in 2022

The new installation at Veolia’s site will account for 25,000 tons of CO2 savings.

WAGABOX® by Waga Energy implemented by Air Liquide in Rockford, Illinois (United States) in 2023

WAGABOX® by Waga Energy implemented by SUEZ in Milhac-d'Auberoche (France) in 2022

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.

The Environmental Benefits

  • Recovers 90% of the methane contained in landfill gas, allowing an energy yield up to three times higher than CHP
  • Once commissioned, the solution injects biomethane 24/7, around the year
  • By April 2022, 13 WAGABOX® units were operating in France with 480 GWh of installed capacity
  • 37,000 metric tons of CO2eq avoided by substituting fossil natural gas since the commissioning of the 1st WAGABOX® unit in 2017 (April 2022)
  • 145 GWh of renewable natural gas injected into the French gas grid to substitute fossil fuel in 2021

The Financial Benefits

  • On a large capacity landfill, production cost can be between 40-70 € /MWh
