Biomass, as a renewable energy source, is biological material from living, or recently living organisms.[1] 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 miscanthus, switchgrass, hemp, corn, poplar, willow, sorghum, sugarcane,[2] and a variety of tree species, ranging from eucalyptus to oil palm (palm oil).
