How energy is harnessed from biogas?

Biogas is harnessed by capturing methane-rich gas produced from the anaerobic digestion of organic matter, such as agricultural waste, food scraps, and manure. This biogas can be used directly for heating or converted into electricity via combustion in gas engines or turbines. Additionally, it can be upgraded to biomethane, which is suitable for injection into natural gas grids or used as vehicle fuel. The process not only generates renewable energy but also reduces greenhouse gas emissions by managing organic waste.
