DuPont’s Cellulosic Plans

DuPont has been digesting its acquisition of Danisco for a while now, and has sent out an update about what used to be called DuPont Danisco Cellulosic Ethanol – now shortened, as you might guess, to DuPont Cellulosic Ethanol. In a press release, DuPont says the effort will now be led by Steven J. Mirshak, who will scoot over from his position as president of DuPont Tate & Lyle Bio Products.

The firm is still planning to build a cellulosic ethanol plant in Nevada, Iowa. Like another Iowa cellulosic ethanol plant being built by corn ethanol producer Poet, DuPont also is pushing a parallel effort to gather up the corn stover needed as a feedstock. It is a part of something called the Stover Collection Project, with Iowa State University.

Meanwhile, back at the ranch, otherwise known as DuPont’s demonstration facility in Vonore, Tenn., the company “continues to make advancements” in preparation for scale-up, though we don’t learn what those are. Nearby, DuPont partner firm Genera Energy (which is connected to the University of Tennessee) is harvesting test fields of switchgrass. Genera held a recent field day where the company showed visitors the switchgrass varieties as well as the equipment used to harvest them.

We here at Cleantech Chemistry will be monitoring  progress toward large-scale production of cellulosic ethanol. As a recent report from the National Academies has pointed out, the U.S. is way, way behind  where it is supposed to be this year in producing the stuff.
