Biogas systems are technologies that convert organic waste into renewable energy in the form of biogas. This process typically occurs in an anaerobic digester, where microorganisms break down materials like food scraps, agricultural waste, and manure in the absence of oxygen. The resulting biogas primarily consists of methane and carbon dioxide, which can be used for heating, electricity generation, or as a vehicle fuel. These systems not only produce energy but also help manage waste and reduce greenhouse gas emissions. By utilizing organic materials that would otherwise decompose and release harmful gases, biogas systems contribute to a more sustainable and circular economy.
