Humans discovered ethanol not long after they figured out how to put fire to good use. Today, ethanol has many uses: you can drink it – diluted, of course; use it in food and other manufacturing; and blend it with petrol to make a truly sustainable and renewable transport fuel.
Bioethanol - or simply ‘ethanol’ - is an alcohol which is made by fermenting the sugar and starch components of plant materials by using yeast such as saccharomyces cerevisae.
Ethanol can be used as a fuel for vehicles in its pure form as a replacement for gasoline, but it is usually blended with gasoline so as to improve vehicle emissions.
