Biomass is a term used to describe all organic matter produced
by photosynthesis, existing on the earth’s surface. They
include all water- and land-based vegetation and trees, and all
waste biomass such as municipal solid waste (MSW),
municipal biosolids (sewage), and animal wastes (manures),
forestry and agricultural residues, and certain types of
industrial wastes. The world's energy markets have relied
heavily on the fossil fuels. Biomass is the only other naturally
occurring energy-containing carbon resource that is large
enough in quantity to be used as a substitute for fossil fuels
