DuPont’s $500 million winning ethanol bet

DuPont's $500 million (€391 million) bet on producing ethanol from corn crop waste will pay off as companies add to demand for renewable chemicals and fuels.

The US chemical company is investing in building a biorefinery in Nevada, Iowa, on research and development for enzymes to break down corn waste into ethanol.

DuPont will supply cellulosic ethanol to Procter & Gamble's Tide Coldwater liquid laundry detergent, in the company's first commercial scale-up of its kind.

The biorefinery will be completed in the coming months.
