Never Enough Waste To Fuel Department

A company called Xethanol is currently looking for sites to turn biomass into ethanol. By "biomass" they largely mean waste that has already been abandoned or landfilled, so we are looking at removing waste and converting it into fuel. As there is increasing dispute against using switchgrass as an ethanol source, and since corn ethanol is incredibly wasteful, I'm intrigued to see if Xethanol can prosper with using abandoned wastes.
