Biomass is an important renewable resource that has gained increasing importance in our surroundings because of the growing demand for energy and the need to protect the environment. Biomass refers to organic materials obtained from plants, animals and other biological sources. Agricultural residues, wood, animal dung, food waste, forest residues and certain types of municipal waste are common examples of biomass. Since these materials can be naturally replenished, biomass is considered a renewable source of energy. The importance of biomass can be understood from its contribution to energy production. Biomass can be converted into useful forms of energy such as heat, electricity, biogas and biofuels. In rural areas, agricultural waste and animal dung can be used to produce biogas for cooking and other household requirements. Biomass-based electricity can also support local energy needs, particularly in areas where conventional electricity supply is limited. Biofuels produced from biomass can be used as alternatives to petroleum-based fuels. Biomass also plays an important role in waste management.
