What are the byproducts of ethanol production?
Ethanol byproducts (co-products) include distillers dried grains (DDGs), corn bran, corn gluten feed, corn gluten meal, corn germ meal and condensed fermented corn extractives. Every bushel of corn made into ethanol yields 18 pounds of DDGs, which are used as livestock and poultry feed. Nearly 3.8 million tons of DDGs are created in domestic dry grind ethanol production.
