The Johnson County Landfill is the largest privately owned landfill in the United States, encompassing over 700 acres in the northern region of Johnson County, Kansas. Located in the metro Kansas City area, the landfill services twelve counties in Kansas and Missouri and has a projected active life that extends through 2023 with useful methane production expected well beyond that date. Landfill Energy Systems, through its wholly owned subsidiary EIF KC Landfill Gas, LLC (KCLFG), owns and operates the well field gas collection system and landfill gas (LFG) processing facility on the Johnson County Landfill. The landfill is currently producing approximately 4,000 standard cubic feet per minute (scfm) of landfill gas. This is the equivalent of producing approximately 2,800 MMBtu of natural gas per day. The LFG currently produced at KCLFG has the potential of generating approximately 13 MW, or enough electricity to power 10,000 homes.
The 6.3 MMScfd gas facility processes the LFG by removing the majority of the non-methane components including CO2, water, sulfur and volatile and non-volatile organic compounds to attain pipeline quality. The KCLFG facility uses a modified Selexol-type scrubbing system to treat the gas. In April 2008, LES, completed the acquisition of the KCLFG facility and is currently responsible for the operations and asset management of the facility.
