Biofuels
Biofuels are all kinds of liquid, solid and gaseous fuels produced from biological raw materials in large quantities and rich in hydrocarbons. In Spain, typical example is the development of a project to use orange peels to produce.
Biofuels are resulting from biomass processing, which in turn is a renewable source. After the first oil crisis of 1973 Biofuels are considered energy source (substitute) fossil fuels for transport and can be easily integrated into the system of fuel supply.
