"Cellulosic ethanol technology is a lot closer to reality than a lot of articles would have you think," said Jacques Beaudry-Losique, manager of the Department of Energy's Biomass Program this morning at the American Association for the Advancement of Science meeting. After some well-publicized studies stated that corn-based biofuels might exacerbate CO2 damage to the environment, focus has shifted to these so-called "second generation" biofuels that use non-food crops such as switchgrass, wood chips or crop residues (e.g. all the parts of the corn plant that are currently wasted after harvest--the stalk, leaves and "cob").
