Bioethanol is a chemical compound that has got applications in the chemical industry and in the liquid fuels industry for the transportation sector; it is obtained at industrial scale from the fermentation of sugars, present in feedstocks such as cereals (wheat, barley, corn and sorghum).

Bioethanol is used mainly as a pure fuel or in blends with gasoline or diesel and it has got several advantages over fossil fuels:

• Renewable origin.

• It is a biodegradable product.

• Greater independence from oil imports. Its use contributes to energy autonomy and diversification.

• Cleaner fuel in terms of pollutant emissions such as sulfur oxides and particulate matter.

• It contributes to growth of local economies and income redistribution, creating jobs in rural areas.

• It reduces greenhouse gas (GHG) emissions, which contribute to warming the earth’s surface and accelerate climate change.

• It is easy to produce and store.
