As an vitality supply, biomass can either be used directly through combustion to produce heat, or indirectly after changing it to numerous forms of biofuel Conversion of biomass to biofuel may be achieved by different methods, that are broadly classified into: thermal, chemical, and biochemical methods.
The main various vitality supply for transportation fuel was biofuels, with ethanol main the market. Alternatively, various energy could be widely produced with fundamental gear and natural processes. In contrast to biomass vitality sources, biofuels make use of animal and flora to create vitality.
