Al-Corn, Clean Fuel: Ethanol

Dry milling – The whole corn kernel is ground into a powder, mixed with water to form a mash (similar to oatmeal) and then cooked with enzymes that turn the starch into glucose.The mash is fermented and distilled to separate the ethanol from the solids and water, which becomes a high quality livestock feed called distillers grains.

Corn ethanol - Wikipedia

Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States.Corn ethanol is produced by ethanol fermentation and distillation.It is debatable whether the production and use of corn ethanol results in lower greenhouse gas emissions than gasoline. Approximately 40.5% of the U.S. corn croplands are used for ethanol production.

How is Ethanol Made? | Renewable Fuels Association

After steeping, the slurry is processed through grinders to separate the corn germ. The remaining fiber, gluten and starch components are further segregated. The gluten component (protein) is filtered and dried to produce animal feed. The remaining starch can then be fermented into ethanol, using a process similar to the dry mill process.
