The Indian River County Landfill has a voluntary landfill gas collection system that needs periodic expansions to continue to capture the methane gas to reduce odors, reduce the risk of fires and to reduce it to the less harmful carbon dioxide via flaring in the short run, and ultimately facilitate the sale of the landfill gas to NoPetro EcoDistrict (NED) for its renewable natural gas (RNG) project.
