Landfill Gas

Landfill gas is piped from the nearby landfill to the power station where it is burned in engines to generate electricity. Impurities in the gas must be filtered out so they don't clog catalytic filters on the engine. This generator is a 1.6 MW generator. This power station is in Lincoln Nebraska. Landfill gas is mostly methane (~60%) carbon dioxide and other impurities.
