If you are already doing landfill and other possible disposal solutions are either inaccessible or too costly, LFG is a good option. This method relies on capturing methane gas from existing landfills to help generate electricity and simultaneously reduce GHG emissions. The methane gas serves as an energy source to power turbines and, in turn, the turbines generate electricity for the grid. As biodegradable waste, wood poles and other untreated wood material produce methane during the degradation process.
