Former Royal Dutch Shell executive joins leadership team

Lakewood, Colo. - March 15, 2011 - ZeaChem Inc., a developer of biorefineries for the conversion of renewable biomass into sustainable fuels and chemicals, announced today it has added energy industry executive Bob Walsh to the leadership team as Chief Commercial Officer. Based on his experience in the global energy and renewable fuels industries, Walsh will lead the company's drive to commercialize a robust portfolio of biobased fuels and chemicals from cellulosic feedstocks. Walsh joins the company following the accomplishments of the June 2010 groundbreaking and key financial milestones of ZeaChem's 250,000 gallon-per-year biorefinery in Boardman, Ore, which is currently under construction.

Walsh's primary responsibility is to grow ZeaChem's commercialization efforts, and he brings decades of direct industry experience and relationships to his newly appointed position. Most recently, Walsh served as CEO and director of Aurora Biofuels in Alameda, Calif., which he joined after executive roles with LS9 and Royal Dutch Shell. Walsh spent 25 years with Shell in manufacturing, supply, trading and strategic planning roles in both the U.S. and Europe.

“Bob brings a proven track record of delivering outstanding results from his extensive experience in the refining and chemical industries,” said Jim Imbler, president and CEO of ZeaChem. “His international experience will be particularly useful to ZeaChem as we seek to broaden our markets with our product platforms.”

ZeaChem's Boardman biorefinery, which will begin to come online in 2011, will convert biomass into ethanol and chemical building blocks including acetic acid and ethyl acetate. The company plans to partner for commercial production plants based on successful operations at Boardman.
