Des Moines Register: DowDuPont plans to find a buyer for its ethanol plant in Nevada, Iowa, a 30 million-gallon, $225 million operation that uses corncobs, husks and stalks to produce the biofuel. DowDuPont has shuttered operations and cut 90 workers. The move is part of DowDuPont’s announcement today that it will cut its global workforce by 5 to 7 percent, consolidate and shut down some buildings and facilities, and centralize purchases. The company was unable to outline how Iowa workers might be affected. DuPont Pioneer employs about 2,600 workers in Johnston.
