Garbage Is Dirty, But Is It A Clean Fuel?
About 45 minutes north of downtown Los Angeles, a machine the size of a small truck flattens tons of food scraps, paper towels and other household trash into the side of a growing 300-foot pile. To Waste Management which operates the landfill, this is more than just a mountain of garbage. Pipes tunnelled deep into the mound extract gas from the rotting waste and send it to a plant that turns it into electricity.
