Turning trash into ethanol?

Another reason to forget corn?

Fulcrum BioEnergy wants Americans to forget about corn-based ethanol. Instead, Fulcrum would prefer to turn organic garbage into ethanol. More interesting, the company can turn trash into fuel for less than $1.00 per gallon in an energy positive, carbon negative way according to the company.

While turning trash into fuel is a great idea, is ethanol the right fuel? Many companies are currently using methane from trash to power factories and such. Which technique is better? Might it not be better to keep trash energy local, rather than transporting this energy?
