Bio Ethanol Fuel

Today we discussed how to make bio ethanol. Bio ethanol is most often used as motor fuel. The ethanol that is found in this fuel is the same alcohol that is in alcoholic beverages. Bio ethanol is a form of renewable energy that can be produced from agricultural feedstocks. It can be made from corn, sugar cane, potato and manioc. The basic steps fror large scale production of ethanol are yeast fermentation of sugars, distillation, dehydration and denaturing.

There are pros and cons to Bio ethanol. Some pros are that through the use of bio ethanol, some of these CO2 Green house emissions will be reduced as the fuel crops absorb the CO2 they emit through growing. Also, it will reduce dependence on Oil. Some cons are that bio ethanol can be corrosive to metals such as aluminum. Also, it may require the use of too much arable land and too much energy input during the production process to justify it.
