UPTON, Wyo. (AP) - In the tiny town of Upton, KL Energy Corp's test plant is among those at the forefront of a concerted research effort to turn trees, waste wood and other plants into automobile fuel. The Rapid City, S.D.-based company is hoping to capitalize on doubts about corn ethanol and the federal government's embrace of biofuels as a way to create jobs, help replace imported oil and protect the environment. The government has also touted wood biofuel as a way to create markets for small wood and low value trees on federal forest lands. KL's process turns the wood into 200-proof liquid ethanol. A company executive says it plans to build plants based on its Upton model near forests around the country.
