BIOMASS

Biomass, as a renewable energy source is biological material from living, or recently living organisms.As an energy source, biomass can either be used directly, or converted into other energy products such as biofuel.
In the first sense, biomass is plant matter used to generate electricity with steam turbines & gasifiers or produce heat, usually by direct combustion. Examples include forest residues (such as dead trees, branches and tree stumps)yard clippings, wood chips and even municipal solid waste. In the second sense, biomass includes plant or animal matter that can be converted into fibers or other industrial chemicals including
biofuels .

Industrial biomass can be grown from numerous types of plants, including ,mischantus,switchgrass,hemp,corn,poplar,willow,sorghum,and a variety of variety of free tree species ranging from eucalipthus,to oil palm.

Biomass is carbon, hydrogen and oxygen based. Biomass energy is derived from five distinct energy sources: garbage, wood, waste, landfill gases, and alcohol fuels. Wood energy is derived both from direct use of harvested wood as a fuel and from wood waste streams. The largest source of energy from wood is pulping liquor or "black liquor a waste product from processes of the pulp, paper and paperboard industry. Waste energy is the second-largest source of biomass energy.
