DuPont hosts Ernst at biofuels enzyme production plant in Iowa

By DuPont Nutrition & Biosciences | August 20, 2019

DuPont Nutrition & Biosciences, a world leader in biotechnology and the production of enzymes that aid in the more efficient production of conventional and cellulosic biofuels, today hosted U.S. Sen. Joni Ernst, R-Iowa, at its plant in Cedar Rapids, Iowa. During a tour and town hall with employees, Ernst and DuPont leaders discussed the positive impact of strong national biofuels policy on America’s farmers, on the environment, and on consumer choice at the pump.

“DuPont applauds Senator Ernst for her tireless advocacy on behalf of biofuels and for the Renewable Fuel Standard (RFS),” said Troy Wilson, global business director for DuPont Biorefineries. “DuPont’s investments in new and advanced biofuel technologies support a strong rural and farm economy when backed by reliable biofuels policy. While we welcome the Environmental Protection Agency’s (EPA) recent action to remove regulatory barriers to allow for year-round E15, it is critical that the agency also end the misuse of small refiner exemptions, which erodes demand for biofuels and ultimately hurts farmers, rural communities and consumers. We thank Senator Ernst for continuing to press the EPA to undo policies that threaten the integrity of the RFS.” 

“Iowa’s economy continues to charge ahead because of innovative employers in our state like the DuPont Nutrition & Biosciences’ production plant in Cedar Rapids,” Ernst said. “I was pleased to hear directly from some of these employees during today’s town hall about their work and what can be done at the federal level, and in cooperation with our state and local partners, to help make sure our economy continues to move in the right direction.”

At its Cedar Rapids plant, DuPont manufactures a full product line of enzymatic and yeast solutions that allow for a higher conversion rate of starch to sugar, which creates greater yields in biofuel production and improves productivity for biofuels producers.
