Brazil's sugar cane-based industry is more efficient than the U.S. corn-based industry. Sugar cane ethanol has an energy balance seven times greater than ethanol produced from corn. [2] Brazilian distillers are able to produce ethanol for 22 cents per liter, compared with the 30 cents per liter for corn-based ethanol. [151]
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses , wood , algae , or other plants.
Ethanol fuel production by state. The United States became the world's largest producer of ethanol fuel in 2005. The U.S. produced 15.8 billion U.S. liquid gallons of ethanol fuel in 2019, and 13.9 billion U.S. liquid gallons (52.6 billion liters) in 2011, [1][2] an increase from 13.2 billion U.S. liquid gallons (49.2 billion liters) in 2010 ...
Ethanol produced from the sugar is a popular fuel in Brazil. [citation needed] The cellulose-rich bagasse is also being investigated for its potential in producing commercial quantities of cellulosic ethanol. For example, until May 2015, BP operated a cellulosic ethanol demonstration plant in Jennings, Louisiana. [citation needed]
First-generation bioethanol is produced by fermenting plant-derived sugars to ethanol, using a similar process to that used in beer and wine-making (see Ethanol fermentation). This requires the use of food and fodder crops, such as sugar cane, corn, wheat, and sugar beet. The concern is that if these food crops are used for biofuel production ...
Saccharum officinarum, a perennial plant, grows in clumps consisting of a number of strong unbranched stems. A network of rhizomes forms under the soil which sends up secondary shoots near the parent plant. The stems vary in colour, being green, pinkish, or purple and can reach 5 metres (16 feet) in height. They are jointed, nodes being present ...
Mechanized harvesting of sugarcane (Saccharum officinarum), Piracicaba, São Paulo. The history of ethanol fuel in Brazil dates from the 1970s and relates to Brazil 's sugarcane -based ethanol fuel program, which allowed the country to become the world's second largest producer of ethanol, and the world's largest exporter.
