Methane from landfills provides fuel for garbage trucks
Talk about going full circle. A garbage truck running on methane picks up the trash out in front of your home and deposits it in a landfill. Over the next few years, that garbage begins to deteriorate, releasing methane gas in the process. That methane waste gas is captured and re-used by the same garbage trucks to pick up your trash. While we aren't necessarily proponents for landfills, at least some good can come out of their creation. Methane gas is a pretty horrible greenhouse gas, so it's much better to capture it in some way than to let it out into our atmosphere. When burned, however, methane (natural gas) releases more energy and less carbon back into the atmosphere that other, more traditional hydrocarbons ... like petroleum-based gasoline. T. Boone Picken's company Clean Energy Fuels has recently made an acquisition for this purpose in Texas.
Another use for the waste-methane emitted from toxic dumps is for electricity generation. Many landfills pipe their natural gas to power-generating facilities where huge turbines could potentially create the power for your next electric car.

You capture much more methane if you stick all the rubbish in an anaerobic digester. Although making one big enough to take the amount that a landfill does would require a massive investment.

Check out a company called BIOferm at www.BIOFerm-ES.com, this is a big company already doing this all around the world, headquarteres in Germany, with plants already running. They just made a presentation to our town for a plant here in Montana.

Cheers for the link Doug. I can't recall if it's BIOferm but I've read about a company do this stuff on quite a big scale in South Africa.

do you guys know the geographical areas where methane gas would be feasible?

can any body tell me about the exact mechanism of how the methane gas is generated from rubbish, such as what is the role of the bacteria.
