Ethanol Production - How Is Ethanol Made? | Infinita Biotech
Currently, most ethanol intended for industrial use is produced from ethylene, a petroleum product. Beverage ethanol is produced by fermentation of starch and sugar-rich feed-stacks. Use of cellulose will provide a renewable feedstock for industrial ethanol yet will not compete with the supply of food.

Ethanol Production Business Plan | Pro Business Plans
Ethanol is produced from biomass mostly via a fermentation process using glucose derived from sugars (sugar cane, sugar beet and molasses), starch (, wheat, grains) or cellulose (forest products) as raw materials. In this form, it is renewable. Synthetic ethanol can also be produced from non-renewable sources like coal and gas.
