Overview

​Valero's Jefferson ethanol plant is located near Jefferson, Wisconsin, about halfway between Madison and Milwaukee off of Interstate 94. The biorefinery sits on 344 acres and started ethanol production in January 2008. The facility uses a dry-grind fractionation production method and state-of-the-art technology to maintain industry-leading standards in production, safety, product quality and environmental stewardship. The Jefferson plant annually processes approximately 41 million bushels of corn into approximately 110 million gallons of un-denatured ethanol and approximately 352,000 tons of high-value co-products including distillers grains, bran, germ and CO2. The biorefinery employs approximately 80 full-time personnel.

The entire kernel of corn is processed. Ethanol is an environmentally friendly, high-octane renewable fuel produced by fermenting converted corn starch with yeast. It is used as a blending agent with gasoline. Distillers grains are the co-product left after the ethanol is removed from fermented corn mash, and are sold as a valuable livestock feed. Jefferson’s distillers grains are very high in protein, and contain fat, vitamins and minerals, making an excellent feed supplement for beef and dairy cattle, swine and poultry. The Jefferson plant markets dried distillers grains as well as a bran-plus-syrup mix and corn germ.
