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.
