feedstocks for fuel ethanol production. While sugar substances were the feedstock for more than 60% of fuel ethanol production at the beginning of the 2000s, its share decreased to 47% by 2006, when grains accounted for 53% of the production.
Ethanol has a potential market as big as the oil market. It can potentially replace the entire fuel market for gasoline. Futhermore, plastics such as poly
