Today, U.S. ethanol is primarily produced from starch- and sugar-based crops by dry-mill or wet-mill processing. Cellulosic ethanol has not yet been produced commercially. However, several commercial cellulosic ethanol production plants are under construction, and intensive research and development is rapidly advancing the state of cellulosic ethanol technology.
