Products
- Ethanol: A clean-burning, high-octane renewable fuel that is blended with gasoline.
- Fiber Cellulosic Ethanol: An enzymatic process is used to convert waste fibers into cellulosic ethanol, offering a much lower carbon intensity than ethanol and conventional gasoline.
- Distillers Grains: Dried and modified (wet) co-products from the fermenting of sugars (starch) in the corn during the distillation process, consisting of protein, fats, fiber and other solids sold as valuable livestock feed.
- Fuel- and Feed-Grade Corn Oil: Inedible corn oil is extracted during the evaporation process of making ethanol, used to make renewable diesel fuel and livestock feed.

Our largest plants annually process 57 million bushels of corn into 140 million gallons of ethanol and 434,000 tons of distillers grains.
The Science of Ethanol
-
What is Ethanol?
Ethanol is a clear liquid that is blended with gasoline, improving combustion that releases the energy to power the car’s engine.
Ethanol lowers life cycle greenhouse gas emissions at least 30% compared to non-blended gasoline.
-
Is Ethanol Made From Corn I Can Eat?
Ethanol is made from field corn, which typically is used for livestock feed and industrial use. The kind of corn we eat is called sweet corn. Only 1 percent of corn grown in the U.S. is sweet corn for human consumption. The remainder is field corn used for livestock feed and fuels.
-
How Much Corn is Used to Produce Ethanol?
Each year we use approximately 583 million bushels of corn, to supply our ethanol plants.
-
How Many Products Do You Get From Corn?
Processing corn results in ethanol, distillers grains and fuel- and feed-grade corn oil.
-
What are Distillers Grains?
Distillers grains are the co-product from the fermenting process, consisting of protein, fat, fiber and other solids. These can be dried or modified (partially dried).
Because of its concentration of nutrients, distillers grains are a valuable livestock feed for cattle, swine and poultry.
