Bioethanol is a fuel made from the fermentation of carbohydrate-rich biomass such as sugar and starch, and has an alcohol content of at least 99% by volume, making it practically water-free. Bioethanol can essentially be produced from any raw material that contains either sugar or starch. In Europe, the most important raw materials used to produce bioethanol include all crops containing starch, as well as concentrated sugar beet juice. In the USA, bioethanol is largely made from corn, while in tropical regions, particularly in Brazil, sugar cane has become the sole source of this fuel. |
Biodiesel is a fuel made from vegetable oils or animal fats. In Europe, biodiesel is made from rapeseed and from used cooking oil and animal fat. In other parts of the world, raw materials such as palm oil and soya are also used to produce biodiesel. In line with legal admixture obligations, biodiesel is added to diesel and sold as 100% biodiesel at filling stations throughout Austria. |
