Landfill gas is produced when anaerobic conditions are created through the compaction of waste materials and then covering them with layers of soil and other materials. The anaerobic digestion of the organic waste materials will produce gases (methane, CO2, and others). The gas builds up and then gas collecting systems (like the one shown above) can capture the gas for refinement and processing.
Once the gas is captured it is then piped to a nearby facility where it is dried and refined. The conditioner pictured above aids in the refinement of the landfill gas for it to be used in an internal combustion engine.
This engine is powered by the landfill gas and produces enough power for 1,000 homes.
There is also a back-up flare on-site for direct burning of the landfill gases.
