Biomethane is a renewable energy source produced from organic materials, such as food waste, agricultural residues, and animal manure. Through a process called anaerobic digestion, microorganisms break down these materials in the absence of oxygen, resulting in biogas, which primarily consists of methane. This biogas can be further purified to remove impurities, yielding biomethane that can be used as a clean fuel. Biomethane can be utilized in various applications, including electricity generation, heating, and as a vehicle fuel. It contributes to reducing greenhouse gas emissions and helps in managing waste, making it an important component of sustainable energy solutions.
