What Is Ethanol?

How Ethanol is made:

The production of ethanol or ethyl alcohol from starch or sugar-based feedstocks are among man's earliest ventures into value-added processing. While the basic steps remain the same, the process has been considerably refined in recent years, leading to a very efficient process. There are two production processes: wet milling and dry milling. The main difference between the two is in the initial treatment of the grain.

Importantly, companies today are involved in technological innovations such as cold starch fermentation, corn fractionation and corn oil extraction. Companies are also utilizing biomass gasification and methane digesters to reduce natural gas consumption. Additional work is being done to reduce energy consumption and production costs, increase efficiency and reduce emissions using the best available control technologies.
