Corn ethanol represents the first generation of biofuels. Cellulosic ethanol, made from grass, woody plants, and crop debris, was supposed to be the second generation.
The Spanish energy company Abengoa opened the world's largest cellulosic refinery in Hugoton, about 90 miles southwest of Dodge City, Kansas, said Biofuels Digest.
With Abebgoa to open its $300 million celllulosic ethanol plant in Kansas on Friday, the Minneapolis Star Tribune says there is worry within the industry that debut of large-scale cellulosic plants in the United States may also be the closing act for big plants domestically.
The EPA proposal to relax the ethanol mandate could pinch the market for biofuels made from crop debris, grass and wood, says a front-page story in the Des Moines Register.
