Biomethane serving the circular economy: providing energy by recovering waste

Air Liquide purifies biogas from the fermentation of organic and agricultural wastes to obtain biomethane. It is then injected into the domestic grid or liquefied for transportation, storage and distribution as a clean alternative fuel or as industrial fuel. 

  • 20 biomethane production units around the world, including 2 inaugurated in 2020
  • 250,000 tons of CO2 avoided over the last 3 years
