KL Process Design Group of Rapid City, S.D. has been producing cellulosic ethanol from wood chips on a small scale in Upton, Wyo. since last March.
"It is now possible to economically convert discarded wood into a clean burning, sustainable alternate motor fuel" said Randy Kramer, president of KL Process Design Group. "We’re proud of what this small company has accomplished, and believe that our design will be a cornerstone from which we can build our country’s renewable fuel infrastructure providing a better source of motor fuel, starting today."
The plant is the result of more than six years of developmental research between KL and the South Dakota School of Mines and Technology. Although primarily using soft woods, the plant has made test runs using cardboard and paper as feedstocks.
According to KL, the plant will increase production to 2.5 million gallons of cellulosic ethanol per year.
