Ethanol Biofuel

The largest national use of ethanol biofuel exists in Brazil (gasoline sold in Brazil contains at least 20% ethanol and hydrous ethanol is also used as fuel). In order for ethanol (ethyl alcohol) to be suitable for use as a replacement to petrol in its pure form, it must be distilled to at least 70-80% purity by volume before use.

Today almost 50% of Brazilian cars are able to use 100% ethanol biofuel, that includes ethanol only engines and flex fuel engines. Flex fuel engines are able to work with all ethanol, all gasoline or any mixture of both, giving the buyer a choice between price and performance.

Biodiesel is diesel fuel made from animal or vegetable materials. ..fewer pollutants than petrodiesel, although they also generally get slightly fewer miles per gallon
