The dominant ethanol feedstock in warmer regions is sugarcane. [8] In temperate regions, corn or sugar beets are used. [8] [9] In the United States, the main feedstock for the production of ethanol is currently corn. [8] Approximately 2.8 gallons of ethanol are produced from one bushel of corn (0.42 liter per kilogram).
In Brazil where sugar cane is used, the yield is higher, and conversion to ethanol is more energy efficient than corn. Recent developments with cellulosic ethanol production may improve yields even further. [12] In 2006 a study from the University of Minnesota found that corn-grain ethanol produced 1.25 units of energy per unit put in. [13]
Ethanol is commonly made from biomass such as corn or sugarcane. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 ...
Historical trend of Brazilian production of light vehicles by type of fuel, neat ethanol (alcohol), flex fuel, and gasoline vehicles from 1979 to 2017. [14] Brazil was until recently the largest producer of alcohol fuel in the world, typically fermenting ethanol from sugarcane.
U.S. sugarcane production occurs in Florida, Louisiana, Hawaii, and Texas. The first three plants to produce sugarcane-based ethanol went online in Louisiana in mid-2009. Sugar mills in Lacassine, St. James and Bunkie were converted to sugarcane ethanol production using Colombian technology to enable
In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol used as fuel. Sugar cane plantations covered 3.6 million hectares of land for ethanol production, representing just 1% of Brazil's arable land, with a productivity of 7,500 liters of ethanol per hectare, as ...
"America's ethanol program is a product of government subsidies. There are more than 200 different kinds, as well as a 54 cents-a-gallon tariff on imported ethanol. This prices Brazilian ethanol out of an otherwise competitive market. Brazil makes ethanol from sugarcane rather than corn (maize), which has a better EROEI. Federal subsidies alone ...
Likewise, the production of ethanol, lactic acid or methanol and ethanol-lactic acid from sugarcane bagasse have been studied; [12] lactic acid demonstrated to be economically attractive by showing the greatest net present value (M$476–1278); in the same way; the production of ethanol and lactic acid as co-product was found to be a favorable ...
