 Biomass - Wikipedia, the free encyclopedia
The term biomass is especially useful for plants, where pickle some internal structures may not always be considered living tissue, such as the wood (secondary xylem) of a pickle tree.
Biomass is grown from several plants, including switchgrass, hemp, corn, and sugarcane.
Although fossil fuels have their origin in ancient biomass, pickle they are not considered biomass by the generally accepted definition because they contain carbon that has been 'out' of the pickle carbon cycle for a very long time.

Biomass such as waterwaste (sewage), manure, or food processing waste, is mixed with water and fed into a digester tank without air.
Biomass absorbs carbon dioxide during growth, and emits it during combustion, therefore, it recycles atmospheric carbon and does not add to the greenhouse effect.

 Biomass Energy Home Page Biomass Energy
Biomass is a renewable energy source because the growth of new plants and trees replenishes the supply.
If the amount of new biomass growth balances the biomass used for energy, bioenergy is carbon dioxide "neutral." That is, the use of biomass for energy does not increase carbon dioxide emissions and does not contribute to the risk of global climate change.

Additionally, when biomass is heated, carbon monoxide and hydrogen (biosynthesis gas) is produced in great amounts to be later used in the production of plastics, acids, and synthetic fabrics.

 Electricity from Biomass
The term "biomass" encompasses diverse fuels derived from timber, agriculture and food processing wastes or from fuel crops that are specifically grown or reserved for electricity generation.
Because biomass technologies use combustion processes to produce electricity, they can generate electricity at any time, unlike wind and most solar technologies, which only produce when the wind is blowing or sun is shining.
Biomass fuels may be obtained from supplies of clean, uncontaminated wood that otherwise would be landfilled or from sustainable harvests.

 Tiempo Climate Cyberlibrary, Tiempo - Issue 29, Biomass as an energy source
It has, however, been recognized for at least a decade that growing and using biomass on a continuous basis as a substitute for fossil fuels has clear advantages compared to using the biomass solely as a means to sequester carbon to create a carbon sink.
The contribution of all forms of biomass (137 million tonnes oil equivalent) to reducing carbon dioxide emissions would total about 150 million tonnes of carbon by the year 2010, that is, a reduction of 17 per cent, twice the European Union’s obligation under the Kyoto Protocol.
A clear point for policy makers is that trees and other forms of biomass can act as carbon sinks, but at maturity or at their optimum growth rate there must be plans to use the biomass as a source of fuel to offset fossil energies (or as very long-lived timber products).

Biomass is considered a renewable resource because new growth typically replaces that of the decaying plants and trees.
Biomass can be converted to a solid, liquid, or gas fuel or burned directly to produce steam to drive an electric generator.
Although the burning of biomass does release some air pollutants, since biomass is part of the carbon cycle, carbon dioxide emissions are substantially reduced or nearly equal to what was captured during its growth phase.

 WEC Survey of Energy Resources 2001 - Biomass
The inability to fully address the indigenous biomass resource capability and its likely contribution to energy and development is still a serious constraint to the full realisation of this energy potential, despite a number of efforts to improve biomass energy statistics.
The increasing interest in biomass for energy since the early 1990's is well illustrated by the large number of energy scenarios showing biomass as a potential major source of energy in the 21st century.
Thus, if biomass is considered primarily as a substitute for coal, using modern conversion technologies for producing either electricity or liquid synfuels, the effect on atmospheric CO would be comparable to that which could be achieved with carbon sequestration, per tonne of biomass produced.

 Bioenergy and Biomass Frequently Asked Questions
Biomass is a scientific term for living matter, but the word biomass is also used to denote products derived from living organisms - wood from trees, harvested grasses, plant parts and residues such as twigs, stems and leaves, as well as aquatic plants and animal wastes.
If biomass is cultivated and harvested in a way that allows regrowth without depleting nutrient and water resources, it is a renewable resource that can be used to generate energy on demand, with little net additional contributions to global "greenhouse gas" emissions.
Installed capacity of biomass power generation worldwide is about 35,000 MW, with about 7,000 MW in the United States derived from forest-product-industry and agricultural residues (plus an additional 2,500 MW of municipal solid waste-fired capacity, which is often not counted as part of biomass power, and 500 MW of landfill gas-fired and other capacity).
