Question: What is biofuel and how does it work?

Answer:Biofuel refers to several kinds of fuel sources that are all made from organic matter or biomass. The main biofuels produced and used today are bioethanol and biodiesel. Today bioethanol is produced by the fermentation of corn. Most of the research in this field is directed toward finding other biomass with less environmental demand than corn that we can use for industrial production of ethanol. Corn’s high environmental demand means that it pulls lots of nutrients from the soil as well as its high water demand. Finally, corn is also a food source, in addition to being a fuel production source, so the interaction of these two markets has brought about unexpected results in pricing. Biodiesel are oils derived from vegetable and/or animal fats. The most common are used oils that are waste products of cooking establishments where, once they have been used in food preparation, the oil is disposed of because it is no longer useful.

Diesel engines can can successfully burn biodiesel with limited modifications. Regular gasoline engines are capable of burning bioethanol and gasoline mixed fuel, but pure ethanol has some issues performing as fuel alone especially because of its low temperature properties.
