Overview

​Valero's Aurora ethanol plant is located near Aurora, South Dakota, six miles east of Brookings and 60 miles north of Sioux Falls. The biorefinery sits on 420 acres and started ethanol production in November 2003. The facility uses a dry-grind production method and state-of-the-art technology to maintain industry-leading standards in production, safety, product quality and environmental stewardship. Recognized as the ethanol industry's first 100 million-gallon-per-year production facility, the Aurora plant now annually processes approximately 48 million bushels of corn into approximately 135 million gallons of denatured ethanol and 400,000 tons of distiller grains co-products. The biorefinery employs more than 70 full-time personnel.

The entire kernel of corn is converted to ethanol or distillers grains. 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. Distillers grains are high in protein, fat, vitamins and minerals, making an excellent feed supplement for beef and dairy cattle, swine and poultry. The Aurora plant markets both dried distillers grains with solubles (DDGS) and modified (or wet) distillers grains with solubles (MDGS).
