Energy efficiency technologies for clean electric power from biomasses: The state of the art and perspectives for the future

This paper reports the results of studies on energy production by using bio-masses. The use of bio-masses is encouraged all over the world due to the increasing prices of oil and natural gas and the growing concern for pollution and CO
₂
emissions as well as to the possibility of using local resources and help local economies. Bio-masses have been classified according to type and production chain. Data on world production of bio-masses and their use for energy transformation are also reported. The main techniques for the energy transformation of bio-masses are investigated and some practical examples are explained in details.
