How is ethanol produced?



  1. 0 Votes

    Ethanol is made from any crop or plant that contains a large amount of sugar or components that can be converted into sugar, such as starch or cellulose. Then this goes through a four step process that turns into ethanol.

    • The crop/plant is grounded for easier processing.
    • Sugar is dissolved from the ground material or starch/cellulose is converted to sugar depending on your material.
    • Microbes feed on the sugar, producing ethanol and CO2 as a byproduct.
    • The ethanol is purified.

    Ethanol can also be produced  through wet-milling process which has high fructose corn syrup as a product (a sweetener).

    Ethanol is produced from plants such as sugar cane, sugar beets, corn, wheat, and barley. These plants are then ground up. After this happens, either sugar is dissolved from the plant or cellulose or starches in the plant are converted into sugar. Microbes then feed upon this sugar to produce ethanol and carbon dioxide. Lastly, this ethanol is purified to make it suitable for use.
