Greenhouse gas (GHG) emissions are a hot-button topic within the landfill industry and society as a whole. Landfills naturally generate GHGs in the form of landfill gas (LFG) and generally collect these gasses and will often use them for beneficial end uses. However, even at world-class landfills, GHGs are emitted through things like gaps in LFG collection system coverage, insufficient cover, blown traps, piping leaks, malfunctioning equipment, etc. We have successfully used several different technologies to help identify and reduce GHG emissions. We will share our thoughts and experiences on how different technologies can be deployed at landfills to help identify, quantify, and reduce GHG emissions.
