From the point of view of energy generation, the term biomass is derived from recently living organisms or used as fuel to produce them. From the point of view of ecology, biomass is the total amount of living matter in an ecosystem or a plant or animal population. The two concepts are linked. Although, they are different.
In the definition of biomass for the power generation are excluded the traditional fossil fuels, although these are also derived from plant life (coal) or animal (oil and natural gas) but are the result of several changes that require millions of years to happen. Biomass can be considered a renewable natural resource, while fossil fuels are not renew the short term.
THe biomass is used in the production of energy from processes such as the burning of organic material produced and accumulated on an ecosystem, but not all the primary production begins to increase the plant biomass of the ecosystem. Part of the stored energy is used by the ecosystem for their own maintenance. The advantages are the low cost, is renewable, allows the reuse of waste and is less polluting than other forms of energy such as that produced from fossil fuels.
The burning of biomass causes the release of carbon dioxide in the atmosphere, but as this compound had previously been absorbed by plants that led to fuel, the balance of CO2 emissions is zero.
