Alabama biofuel project turns tree limbs into ethanol
The country's first program to turn wood waste, such as tree limbs, into biofuel is under way in Hoover, Ala. The first shipment of E-85, an 85% ethanol-gasoline blend, was only 100 gallons, but industry officials hope it is just the beginning. The goal is to have a network of small ethanol plants near urban areas so that municipal wood waste can be turned into biofuel and sold for less than the cost of gasoline.
