Though less photogenic than some of their carbon offset project counterparts, landfill gas projects play an essential role in the offset ecosystem, primarily by reducing emissions of methane, a greenhouse gas 28 times more potent than carbon dioxide. In Elba, Alabama, the Coffee County Sanitary Landfill has invested in being part of the climate solution by installing a system to collect and combust landfill gas before it can escape into the atmosphere. Without this project and its control of methane emissions, this county landfill would be a significant methane emission source.
There are 48 vertical wells installed within the Coffee County Landfill, with depths that ranging from 12 feet to 88 feet. A blower creates a vacuum that draws the landfill gas from these wells to the main collection header, where the landfill gas is combusted via a flare. The system now meets the rigorous performance standard defined by the Climate Action Reserve landfill gas protocol.
