Biology alcohol

The United States is the biggest ethanol production country on the world, alcohol commercializes production only then at last centuries 90 time, raw material basically is corn. 2006, 5% what alcohol occupies American benzine to consume gross about, alcohol mix into burns scale to be normally 10% , 46% what add the mixture benzine of alcohol to occupy countrywide benzine to supply gross.

According to the United States but the statistic of association of second birth fuel, up to by 2006, the United States shares 111 alcohol manufacturer, productivity is 16 million tons. Additionally 76 factories and 300 factories lie respectively in construction and plan in. To 2009, alcohol productivity will achieve 34.9 million tons.

Profit margin is low it is another problem. Two years corn price rose nearly 1 recently times, since achieving 10 years top level, alcohol is produced almost already profitless. Ethanol production profit was 2.5 dollars in July 2006 / gallon, dropped in January 2007 to 50 cent / gallon, the level that dropped to be balanced to profit and loss further in Feburary 2007. 2006, every bushel corn is producible 2.8 gallon alcohol, ethanol production cost is 1.14 dollars / gallon, alcohol produces average interest rate to be 25.3 cent about / gallon. Alcohol sale price changes as season happening, was 4.23 dollars in June 2006 / gallon, was 1.68 dollars in September 2006 / gallon, was 1.87 dollars in January 2007 / gallon, was 2.21 dollars in March 2007 / gallon.
