The potential of gas from garbage

Turning garbage into fuel is potentially an answer to two pressing problems—diminishing the world's dependence on fossil fuels and an alternative to burying trash in landfills. In fact, the 468 million metric tons of trash produced in North America each year could provide 47 billion liters of ethanol—or roughly the same amount as produced from corn, which presently supplies 10% of U.S. gasoline demand.

This is actually a low profile success already. The US harvested enough methane from landfills to power 14 million private automobiles in 2009.
All of the commodity plastics can be rendered biodegradable in landfills, by the use of Earth Nurture Additive. The energy locked in the plastic can then be harvested as methane.
The use of these additives to render plastics biodegradable in landfills will add only 16% to the materials component of the treated plastic product, or perhaps 5% of the total price. See: http://earthnurture.com .
