Biomass is the generic term given to dry plant materials and organic wastes. It is also used to describe vegetation and wastes that are subsequently used for conversion into fuel. All biomass products are originally derived from photosynthesis and are potential sources of energy. For centuries biomass has been used by man in the form of wood and charcoal. The fossil fuels oil, coal, gas and peat were also once biomass, transformed over hundreds of thousands of years by natural geological forces and micro-organisms.
