Sugar is extracted using enzymes, then yeast cells convert the sugar into ethanol and carbon dioxide (CO2). The ethanol is stray from the fermentation broth by distillation.

In 2005, the U.S. Congress passed an energy bill that necessitate gasoline exchange in the United States to be motley with ethanol in ord er to decrease the nations dependence on oil! . There is a limit to the amount of ethanol that can be mixed with gasoline in the American market, however. virtually all in advance(p) automobiles can use E10, fuel that contains 10 per centum ethanol. By contrast, E85, containing 85 percent ethanol and just 15 percent gasoline, requires specially equipped flexible-fuel engines.
