Ageing Biofuel is a fuel that is produced through contemporary biological process such as agriculture and anaerobic digestion rather than a fuel produced by geological process such as these involved in the formation of fossil fuels such as coal and petroleum from Prehistoric biological matter. if the source biometer can regrow quickly the resulting fuel is said to be a form of renewable energy.
Biofuels can be diversed directly from plants that is (energy crops) or indirectly from agricultural,commercial, domestic and or industrial wastes. Renewable Biofuels generally involve contemporary carbon fixation such as those those occur in plants or micro Algae through the process of photosynthesis. other renewable biofuels are made through the use of conversion of biomass. this Biomass can be converted to convenient energy containing substances in three different ways;
