Butamax Advanced Biofuels, LLC, a joint venture between BP and DuPont, said it will collaborate with Fagen, Inc. to introduce the commercial production of biobutanol by retrofitting existing ethanol plants using Butamax technology. Fagen is the world’s most experienced biofuels engineering, procurement and construction contractor, having built more ethanol capacity than any other company in the world.”We are delighted to partner with Fagen on our path to commercialize biobutanol,” said Paul Beckwith, Butamax CEO. “Fagen is simply the world leader when it comes to project execution in the biofuels industry, with leading standards for safety and quality.” The first retrofit project will start in 2013. Butamax was the first company to identify the opportunities and technology for cost-effective production of isobutanol through advanced biotechnology. The company announced last December the formation of the Early Adopters Group (EAG), a consortium of world-class biofuel production companies interested in becoming early adopters of Butamax biobutanol technology. Butamax is planning to start commercial production of biobutanol in 2014. (April 19, 2012
