DuPont and NexSteppe to Collaborate on New Feedstocks for Renewable Industry

January 4, 2012

For Immediate Release

Collaboration Aimed at Development of New Sweet Sorghum and High Biomass Sorghum Hybrids

DES MOINES, Iowa, and MALIBU, California, (January 4, 2012) – DuPont and NexSteppe have entered into a collaboration to develop advanced feedstocks for biofuels, biopower and biobased products. The collaboration will focus on the development of new sweet sorghum and high biomass sorghum hybrids which will create additional feedstock options for these rapidly evolving industries.

Under the agreement, DuPont has made an equity investment in NexSteppe, and through its Pioneer Hi-Bred business, will provide knowledge, resources and advanced technologies to help the company accelerate the breeding and commercialization of new hybrids of these crops in the United States and Brazil.

“We’re using science-based innovation and collaboration to develop scalable, sustainable feedstock options for the biobased industries,” said John Bedbrook, vice president for DuPont Agricultural Biotechnology. “Collaborations like this one with NexSteppe will provide new opportunities for growers to address the rising demand for secure, environmentally sustainable and affordable alternatives to fossil fuels.”

Anna Rath, NexSteppe founder and CEO, said, “Sorghum is a crop with significant genetic diversity and great potential that has received relatively little research attention and funding. Combining DuPont’s world-class research and development capabilities with our industry knowledge, experienced team and singular focus, we will be able to rapidly improve the crop to produce feedstocks tailored to the needs of the biofuels, biopower and biobased products industries.”

Sorghum is naturally drought- and heat-tolerant and has the ability to grow in marginal rainfall areas with high temperatures where it is difficult to grow other crops. It has a relatively short growing season and is suitable for crop rotation systems. Sorghum is increasingly grown as a source of feedstock for industrial value chains. Sweet sorghum can be used as a complement to sugarcane in existing Brazilian sugar to ethanol mills, and as a feedstock for advanced biofuels and other biobased products produced from sugars. High Biomass Sorghum is a high-yielding crop that can be used as a feedstock for biopower and cellulosic biofuels. DuPont, through its Industrial Biosciences business, operates and develops industrial processes that use sugar as a feedstock.
