The corn starch and remaining water can be fermented into ethanol through a similar process as dry milling, dried and sold as modified corn starch, or made into corn syrup. The gluten protein and steeping liquor are dried to make a corn gluten meal that is sold to the livestock industry.
Ethanol is commonly made from biomass such as corn or sugarcane. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 × 10 9 liters (4.5 × 10 ^ 9 U.S. gal; 3.7 × 10 ^ 9 imp gal) to more than 52 × 10 9 liters (14 × 10 ^ 9 U.S. gal; 11 × 10 ^ 9 imp gal).
Sugarcane ethanol has an energy balance seven times greater than corn ethanol. [101] As of 2007, Brazilian distiller production costs were 22 cents per liter, compared with 30 cents per liter for corn-based ethanol. [102] Corn-derived ethanol costs 30% more because the corn starch must first be converted to sugar before distillation into ...
Since the 1970s, the U.S. has subsidized ethanol produced from food crops, especially from corn, thus providing a homegrown, alternative fuel source for our automobiles. But for multiple reasons ...
In the 1970s most industrial ethanol in the U.S. was made as a petrochemical, but in the 1980s the U.S. introduced subsidies for corn-based ethanol. [104] According to the Renewable Fuels Association, as of 30 October 2007, 131 grain ethanol bio-refineries in the U.S. have the capacity to produce 7 × 10 ^ 9 US gal (26,000,000 m 3) of ethanol ...
In fact, to make the U.S. corn ethanol industry profitable, lawmakers had to institute a tariff against Brazilian ethanol, which is made with sugar cane. The 54-cents-a-gallon tariff, coupled with ...
There’s ethanol, a fuel made often from corn. There’s cornstarch, which is good for your biscuits, but can also be used for dextrin, which has industrial uses like as an adhesive for bookbinding.
E10 or Gasohol is commonly marketed in Delaware and E85 is found in many states, particularly in the Midwest where ethanol from corn is produced locally. Many states and municipalities have mandated that all gasoline fuel be blended with 10 percent alcohol (usually ethanol) during some or all of the year.
