|Description: Biofuels are alternative fuels made from plant and plant-derived resources. Biofuels are used mainly for transportation. There are two types of biofuels: bioethanol and biodiesel.
Bioethanol, the principal fuel used as substitute for petrol for road transport vehicles, is mainly produced by the sugar fermentation process of cellulose (starch), which is mostly derived from maize and sugar cane. Biodiesel on the other hand is mainly produced from oil crops such as rapeseed, palm, and soybean
