Biogas is a renewable energy source produced from the breakdown of organic materials, such as food waste, animal manure, and plant materials, by microorganisms in an oxygen-free environment. This process, known as anaerobic digestion, generates a mixture of gases, primarily methane and carbon dioxide, which can be used for heating, electricity generation, or as a vehicle fuel. Using biogas helps reduce waste and lower greenhouse gas emissions, making it an environmentally friendly option. Many farms and communities are adopting biogas systems to manage waste and produce energy sustainably, contributing to a cleaner and more sustainable future.
