Landfill Gas
CH4 is one of important greenhouse gases that have to be reduced, but it is 20 times more effective than CO2. CH4 should be separated and purified for effective utilization.
Durability against Contaminants
Water / Humidity: Liquid water should be avoided and less than 80 RH% Small Particles: As few as possible, less than 0.01 µm Residual Oil:
