Biomass
___________________________________________________________________________________________________________________________________________The term biomass refers to the whole of all organic matter of plant or animal origin, which includes materials that come from natural or artificial transformation. The energy that can be obtained from biomass comes from sunlight, which, thanks to the process of photosynthesis, is used by green plants and transformed into energy that is accumulated inside their cells.
This energy can be transferred by the food chain in the animal kingdom. The energy accumulated in the biomass can be released by subjecting it to various processes of energy use.

The use of biomass energy contributes significantly to the improvement and conservation of the environment, since it does not have a significant environmental impact, since the CO2 that is released into the atmosphere during combustion has been previously captured by vegetables during their growth; therefore, the final balance is null.
Applications
Thermal applications
The combustion process of the woody biomass allows to generate a thermal fluid (steam, hot water, thermal oil, etc.) that allows a direct use and the saving of fossil fuels derived from petroli.Thus, in a direct way, the combustion of forest and agricultural waste can be an energy source for heating in the domestic environment, both in individual and collective facilities.
Electrical applications
The combustion of biomass in a boiler allows to generate steam at high pressure and temperature, which expands in a steam turbine generating electricity.It is also possible to use biomass in existing cogenerations (with alternative engines, gas turbines or steam turbines) from gasification and pyrolysis technologies.
