Biomasses are commonly used as electrical/thermal energy, as fuel for transportation and as raw materials for the production of chemicals; the applications for biomass continue to grow and are increasing rapidly. Although there are areas where biomass is effectively used, it is in efficient utilized in direct combustion, especially in less-developed countries.
However, the amount of atmospheric pollution generated remains negligible compared with other pollution sources of energy production.
A wide variety of studies has been conducted on the use of biomass as a source for renewable energy and an alternative to fossil fuels; interest in biomass continues to grow in an increasing trend.
