The word "biofuel" makes most people think of grain ethanol and biodiesel, but an older technology called gasification may be able to be combined with hi-tech nanoscale catalysts to create ethanol from a wide range of biomass, including stiller's grain left over from ethanol production, corn stover from the field, grass, wood pulp, animal waste, and garbage, according to researchers at the Department of Energy's Ames (Iowa) Laboratory. Gasification turns carbon-based feedstocks into...
