Biomass Energy and Environmental Impact

Biomass energy, derived from organic matter, is a renewable energy source. It involves various conversion processes like combustion, gasification, pyrolysis, anaerobic digestion, and fermentation. The choice of process depends on feedstock availability and desired energy form. Biomass remains crucial for many, especially in developing regions, but poses environmental and health challenges, such as emissions and deforestation.
