Bioethanol is a clear, colorless fuel which has a characteristic smell and is mostly used as a petrol substitute for road transport vehicles. The production of bioethanol is done by the sugar fermentation process and chemical process which includes the reaction of ethylene and steam. Fuel and energy crops are the primary sources of sugar which are used for the production of bioethanol. The energy crops such as corn, maize and wheat crops, waste straw, willow and trees, cord grasses, Jerusalem artichoke, sawdust, reed canary grass, and sorghum plants are grown specifically for energy use. Bioethanol is a clean source of energy as it is produced from a renewable resource.
