"There are almost a dozen companies racing to build the first next-generation cellulose ethanol plants in the United States over the next few years. The plants will be built all over the United States. and will churn out bio-fuels made from waste, plant byproducts and woody energy crops. It’s no easy task. Not only do these companies have to build pilot and demo plants, but ultimately large-scale, commercialized refineries that can take years to construct and require hundreds of millions of investment dollars.

While bio-fuels have been getting a bad rap lately, President Bush’s Twenty in Ten Initiative aims to increase the use of renewable and alternative fuels in the transportation sector to the equivalent of 35 billion gallons of ethanol a year by 2017. These 11 companies are focusing on finding the right recipe to make the cellulose ethanol production economically feasible."
