Coupling membrane filtration and cryogenic distillation to upgrade landfill gas into grid compliant biomethane:

• Improvement in energy yield compared with cogeneration.
• Optimized methane capture as there is no limitation in air concentration in landfill gas.

Example: WAGABOX® in Claye-Souilly, France:

• Capacity: 130 GWh/y.
• 21,000 eqCO₂ avoided/y.
• 20,000 households supplied with biomethane.
