First Waga Energy Cryogenic Distillation Module Sold to Air Liquide Passes Acceptance Testing
Air Liquide certified its first Waga Energy cryogenic distillation module after acceptance testing was completed in January. Waga Energy supplied the module for Air Liquide’s RNG plant at the Mallard Ridge landfill in Delavan, Wisconsin.
Waga Energy’s patented cryogenic distillation module separates the methane from the air gases nitrogen and oxygen in landfill gas. At the Mallard Ridge RNG plant, the module is implemented with an Air Liquide membrane filtration system. The plant, now up and running, is already producing RNG—a renewable alternative to fossil-based natural gas—from the landfill gas produced on site and injecting it directly into the local gas grid.
