Much has been made about the inefficiency of producing ethanol from grain, but what if we could instead produce it from garbage, plant waste or even discarded tires?

Using a process that involves microorganisms and a "bioreactor," Coskata claims to be able to produce ethanol for less than $1 a gallon, with a reduction in CO2 emissions of up to 84 percent compared to gasoline production.
