What is the difference between biogas energy and biomass energy pdf?

Biogas energy is produced through the anaerobic digestion of organic materials such as manure, food scraps, and agricultural residues, resulting in the production of methane gas. Biomass energy, on the other hand, involves converting organic materials into heat, electricity, or liquid fuels through processes like combustion or gasification. While biogas is a specific form of biomass energy produced through anaerobic digestion, biomass energy encompasses a broader range of technologies and processes for utilizing organic materials for energy production.
