Oh Replaces Ramsbottom as R.E.G. President

AMES, Iowa (April 14, 2009) - Renewable Energy Group�, the nation's leading biodiesel manufacturer and marketer, today announced Daniel J. Oh, Chief Operating Officer, will transition into the role of President and Chief Operating Officer.

With the announcement, Oh oversees biodiesel manufacturing, sales and marketing, procurement and risk management, production operations and technology services, in addition to alternative feedstock research and commercialization, and corporate development programs for Renewable Energy Group's growing domestic biodiesel business.

Oh takes the reins from Nile Ramsbottom, who has served as Renewable Energy Group's president since the company's incorporation in 2006. Ramsbottom's leadership helped launch REG as a premier producer and marketer of high quality biodiesel. In the nine years Ramsbottom has served at REG and its predecessor West Central Cooperative, the company's biodiesel business has grown from a 1 million gallon-per-year batch plant to a network with the more than 300 million gallons of annual production capacity. Ramsbottom has agreed to forgo full retirement to help strengthen REG's global presence. The new global sales position will be based in St. Louis.

Of the transition Renewable Energy Group Chairman and CEO Jeffrey Stroburg said: "Our board of directors appreciates Ramsbottom's willingness to continue in this new and critical role as he shifts from his position as REG's president and prepares for a personal and professional transition after his 65th birthday in May. In this new position, Ramsbottom will continue pursuing relationships and business with national and international biodiesel customers and large feedstock producers."

Jeffrey Stroburg remains Chairman of the Board and Chief Executive Officer, while Jeff Pattison remains Chief Financial Officer. Renewable Energy Group leads the biodiesel industry by offering a complete biodiesel solution. Renewable Energy Group markets a biodiesel product lineup - REG-9000TM biodiesel, which exceeds ASTM quality specifications - through existing nationwide diesel infrastructure. REG-9000 biodiesel is produced by REG network production facilities consisting of state-of-the-art, proprietary multiple feedstock technology.
