Ethanol is an organic compound made from fermented agricultural products, such as grain, leafy vegetables, and animal waste. Ethanol, unlike other renewable fuel sources can be directly converted into liquid fuels that are also known as biodiesel fuels in order to meet automotive fuel demands. Ethanol is mainly produced through fermentation of sugars and starch and with the help of the necessary bacteria and yeast. There are two ways in order to create ethanol. These are, directly by using the animals' waste and indirectly by using wood and pulp from forests or wood chips.
