Biofuel is a fuel that is derived from biological materials, such as plants and animals, or agricultural, commercial, domestic and/or industrial organic wastes.
A common type of liquid biofuel in use today is bio-Ethanol. It can be used as fuel in engines, cooking stoves and used for other technical purposes (e.g. sanitizers).
Bio-Ethanol can be produced from a variety of feedstocks such as sugar cane, sugar beet, grain, hemp, potatoes, cassava, fruit, corn, wheat, straw etc., as well as many types of cellulose waste and harvesting. To produce it for fuel requires relatively large production, and smaller production units (micro distilleries) are not suitable for that. They can instead be excellent as a basis for e.g. hand sanitizers.
Biofuel can also be in solid form, e.g. wood pellets. Pellets are produced from biomass, raw materials (soft organic materials) like groundnut shell, sawdust, wheat straw, palm husk, rise husks etc. and many other agriculture and forestry wastes. Pellets are highly compressed biomass that may have a high burning value, and it is easily transported and handled. It can also easily be used for automatic feeding.
