Agrofuels are manufactured from biomass and from the by-products of large-scale crop plantations and agro-industries. There are two types of agrofuels, namely, ethanol and biodesel. Ethanol can be manufactured from three types of raw materials: (1) crops with high sugar content (glucose, saccharose), such as sugarcane and sweet sorghum; (2) crops with rich starch content, such as maize, wheat, barley, cassava and rice; (3) materials rich in cellulose, such as wood and agricultural residue (this is the “next generation” agrofuels). The “next generation” agrofuels is not yet commercially available. Biodiesel in turn comes from oil crops, such as rapeseed, palm, moringa, coconut, and jatropha, among others.
