Bio-fuel is a generic term that is used to refer to liquid or gaseous fuels that are produced from a biological source. The term ‘liquid bio-fuel’ is more commonly used to refer to specific types of biofuels used as fossil fuel substitutes. These are further defined by the particular type of biomass from which they are made, and the degree to which they are refined before use. The most common types of liquid bio-fuel are: 1 Straight Vegetable Oils (SVO) - Possibly the simplest form of bio-fuel is pure vegetable oil, such as the oil from peanuts, olives or sesame seeds. This oil has similar energy content and some similar physical characteristics to diesel fuel. In fact the inventor of the diesel engine, Mr. Rudolph Diesel, originally designed his engine to be run on peanut oil. 2 Bio-diesel – This is a product that is made through the ‘trans-esterification of suitable biological oils, and strictly speaking should confirm to a commercial standard such as ASTM D 675. This product is very similar to fossil-based diesel fuel and can be used in almost any type of diesel engine without modification, and has a long shelf life. 3. Ethanol – This can be produced from a wide range of biomass (plant) material using a relatively complex chemical process. Generally the ethanol is mixed with gasoline, in varying concentrations, although cars are now produced for sale in some countries that can run on pure ethanol (“flex-fuel cars”)
