DuPont Industrial Biosciences has been working to develop biofuel technology for more than 25 years. Our enzyme solutions for the conversion of starch to bioethanol are already making significant contributions to targets for renewable energy set in the US and the EU. And our advanced biofuels technology - using biomass feedstocks and more sustainable fermentation techniques - will stimulate new industries, new green jobs and help to power clean economies.
Commercial production of cellulosic ethanol
From the success of our pilot projects, to the imminent commercial scale production of our second generation biofuels, we are at a pivotal stage in the development of cellulosic ethanol as a viable alternative fuel. In 2012, DuPont is scheduled to break ground on our first commercial-scale cellulosic ethanol plant in Nevada, Iowa. Once fully operational, the Iowa facility is expected to produce 27.5 million gallons per year. We're also working closely with local farmers through our award-winning Feedstock Collection Program to secure reliable and sustainable feedstock supplies.
For the conversion of these and other biomass feedstocks, DuPont has developed a market-leading enzyme solution. Accellerase® TRIO is the first single enzyme p roduct to deliver all major enzyme activities required for efficient biomass hydrolysis into both C5 and C6 sugars - often at half the dose of previous enzyme innovations.
Optimizing fermentation yield
The fermentation process comes with a major challenge: eliminating bacteria that can stress or kill the yeast and reduce ethanol yields. Traditional antibiotic use is suspected of contributing to the development of resistant strains of bacteria, and may become subject to regulatory restrictions. DuPont has responded to this challenge with FermaSure® XL, a more sustainable ethanol fuel production process that rapidly attacks and decreases harmful bacteria, while increasing ethanol fermentation rates and efficiency. Using FermaSure® XL routinely results in a 5% improvement in ethanol fuel production. This has the potential to contribute more than 500 million extra gallons of ethanol in the US every year.
It's one more way that DuPont is rising to the global energy challenge, and working for a more sustainable future.
