Biomass Definition (Energy Source)

Biomass is the fuel developed from organic matter waste of living organisms like plant waste, animal waste, forest waste, and municipal wastes.

In biological terms, the word biomass refers to the organic plant matter, which is converted into fuel and used as an energy source. Biomass fuel is considered to be of great importance as it plays the role of a renewable and sustainable source of energy. For example, biomass is used for the production of electricity. Due to this, biomass is capable of replacing fossil fuels.

Organic materials which can be recycled like wood, agricultural wastes, and municipal wastes serve as excellent sources to produce biomass fuel. The biomass can be burnt directly and later converted into methane and ethanol biofuels. Biomass’s chemical composition includes hydrogen, carbon, nitrogen, oxygen, certain alkali atoms, alkaline earth metals and heavy metals.
