As I have mentioned in previous posts, technologies involved in the production of biofuels are constantly evolving and improving. Cellulosic ethanol has received a lot of press in recent years because it has the potential for higher ethanol yields, and it quells the food v. fuel debate that has surrounded corn-based ethanol. The knock has always been that the technology was not where it needed to be for it to compete with corn-based ethanol, however.
As evidence that cellulosic ethanol is headed towards large-scale commercialization, Feedstuffs reports that Gulf Alternative Energy Corp. has agreed to purchase an ethanol plant in Iowa ("Biofuels Buzz" Feedstuffs, August 17, 2009 pg. 14). Gulf plans on converting the plant to into a cellulosic ethanol plant, which will use corn stover, cobs, switchgrass, and animal waste products as feedstocks.
