Landfill gas upgrading into grid compliant Renewable Natural Gas

Waga-Energy upgrades landfill gas into grid-compliant biomethane (also called Renewable Natural Gas or RNG). Thanks to the WAGABOX® technology, which combines membrane filtration and cryogenic distillation, Waga Energy recovers the methane produced spontaneously by the breakdown of organic matter contained in the waste to inject it directly into the gas grid.

Most of waste ends up in landfills. Once landfilled, the organic materials they contain degrade and produce a gas containing a high proportion of methane, mixed with carbon dioxide, air (oxygen and nitrogen) and various pollutants. This biogas is very difficult to valorize because of the presence of air and its highly variable and unpredictable nature.

The result of ten years of R&D, the WAGABOX® technology combines membrane filtration and cryogenic distillation to separate the methane from the other components of the landfill gas. It provides high-quality biomethane that is injected directly into the gas grid. WAGABOX® units are fully automated purification units: they operate 24 hours a day, 7 days a week and are remotely controlled by a supervision device.

Waga Energy deploys this solution worldwide through a dedicated business model: Waga Energy purchases landfill gas from landfill site operators, finances the construction of the WAGABOX® units and their connection to the gas network, and generates income by selling biomethane to energy utilities.

The first WAGABOX® unit was commissioned in France in February 2017 thanks to a grant from Ademe as part of the French government’s economic stimulus program PIA. Four years later, ten WAGABOX® units are in operation in France. They supply 35,000 households and avoid the emission of 45,000 tons of CO2eq per year into the atmosphere by substituting biomethane for fossil natural gas.
