Bioethanol is a spirit produced by biomass, so as to be used as fuel, with the advantage of having a clean combustion. The spirit is produced by a sugar starch, which usually comes from two different sources: 1st generation bioethanol made of "edible" plant parts. 2nd generation bioethanol is made from plant waste or straw. Through a fermentation process, the starch is utilized in the biomass, which is converted to bioethanol. Environmentally speaking, bioethanol is a very good alternative to the most widely used fuel types, as it is CO2 neutral. In addition, the production of bioethanol contributes to an increased self-sufficiency in the energy field
