Methane gas is also a natural by-product of landfills, full of decomposing waste, and can be harnessed here to produce electricity as well. The advantage in burning methane gas is that is prevents the methane from being released into the atmosphere, exacerbating the greenhouse effect. Although this method of biomass energy production is typically large scale (done in landfills), it can be done on a smaller individual or community scale as well.[1]
