Ethanol Production
Today, U.S. ethanol is primarily produced from starch-based crops by dry-mill or wet-mill processing. Cellulosic ethanol has been produced commercially in very small volumes. Several commercial cellulosic ethanol production plants are under construction, and intensive research and development is rapidly advancing the state of cellulosic ethanol technology.
