Of that, approximately 0.2 mmscfd is collected by the system. The gas contains approximately 35.3% methane, which can be captured for energy generation. The facility operates 38 gas collection wells. Flares are in place at this facility. LFG collection reduces greenhouse gas emissions and, in some cases, generates renewable energy for the grid.

Southwest Regional Landfill participates in the following environmental programs: an LFG energy project with status 'Low Potential' is associated with this site. These initiatives help reduce the environmental footprint of landfill operations by capturing resources, reducing greenhouse gas emissions, and diverting material from direct disposal.
