Ethanol production in Brazil uses sugarcane as feedstock and relies on first-generation technologies based on the use of the sucrose content of sugarcane. Ethanol yield has grown 3.77% per year since 1975 and productivity gains have been based on improvements in the agricultural and industrial phases of the production process.
The early technology in flex fuel engines had a fuel economy with hydrated ethanol (E100) that was 25 to 35% lower than gasoline, but flex engines are now being designed with higher compression ratios, taking advantage of the higher ethanol blends and maximizing the benefits of the higher oxygen content of ethanol, resulting in lower emissions ...
2013 – Raízen begins construction of a cellulosic ethanol facility using Iogen technology in Brazil. The facility is located adjacent to Raízen's Costa Pinto mill. Raízen says it plans to expand to eight cellulosic ethanol plants using Iogen's technology. 2012 - Iogen Corporation lays off 150 workers at its Ottawa headquarters.
The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.
Brazil’s production of ethanol fuel from sugarcane dates back to the 1970s, as a governmental response to the 1973 oil crisis. Brazil is considered the biofuel industry leader and the world's first sustainable biofuels economy.
The world's top ethanol fuel producers in 2011 were the United States with 13.9 billion U.S. liquid gallons (bg) (52.6 billion liters) and Brazil with 5.6 bg (21.1 billion liters), accounting together for 87.1% of world production of 22.36 billion US gallons (84.6 billion liters). [1]
"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 ...
UNICA (Portuguese: União da Indústria de Cana-de-Açúcar), the Brazilian Sugarcane Industry Association, is an organization of producers of sugarcane and ethanol fuel. UNICA members are responsible for more than 50% of all ethanol produced in Brazil and 60% of overall sugar production. [1] [2]
