Landfill Garbage Methane Gas Counterpoint

One of the biomass fuels that have been given little attention is methane gas generated from garbage in Waste Management dumps. Waste Management is converting methane gas from rotting trash into electricity power. The gas powers turbines that turn generators, producing electricity for a power grid. In the U.S. the number of methane gas projects has grown to 510 and generate more than 1.563 megawatts per year, or supply energy to power 1.6 million homes. A landfill will produce gas for 20 to 30 years, and is a reliable consistent source. Economics, energy legislation mandates, and technology advancements are the reason for the fuels development. At the present, landfill gas power cost is about the same as from wind, but is still more expensive than from coal-generated power (Cents per kilowatt-hour: Coal=3 to 8, Landfill gas=7 to 10, Wind=5 to 11).

Methane is the second most important green house gas after carbon dioxide. Reducing its emissions in the atmosphere, and using it for energy power generation and a component of natural gas are good reasons landfill methane-electricity projects made up 10.8% of the country’s renewable energy output. The EPA says, landfill methane becomes a greenhouse gas at least 20 times more potent than carbon dioxide, the principle greenhouse gas, when it rises in the atmosphere.

The 1.6 billion tons of garbage, 550 lbs per person, is a growing potential source for clean energy. The methane generated in the landfills should be used for energy power instead of being released to the atmosphere.
