A biofuel is a fuel (such as alcohol / ethanol) that is derived from plant or animal material (biomass) by a biological process such as fermentation or anaerobic digestion. Ethanol and methane are examples of biofuels that can be formed from a variety of sources of biomass.
Ethanol can be used as a fuel (in its pure form) for vehicles or used as a petrol additive to increase the octane ration / improve emissions. It is widely used in Brazil. Ethanol has been produced from a range of plant materials, for example, sweet sorghum, maize, wheat, sugar beet, sugar cane, Miscanthus (elephant grass) and wood pulp. Cellulosic ethanol is derived from biomass such as straw from crops and wood pulp - the latter is particularly rich in lignin and cellulose. Read more...
