Describe how energy is harnessed from bio gas?

Biogas is harnessed by capturing the methane-rich gas produced during the anaerobic digestion of organic materials, such as agricultural waste, food scraps, and manure. This gas is then collected and can be burned in a generator to produce electricity or used directly for heating. Additionally, biogas can be refined to remove impurities and upgraded to biomethane, which can be injected into natural gas grids or used as a vehicle fuel. The process not only generates energy but also reduces greenhouse gas emissions and promotes waste management.
