A biogas plant is a facility that produces biogas through the anaerobic digestion of organic matter. This process, occurring within an oxygen-free environment, breaks down biomass into biogas, primarily methane and carbon dioxide, and a nutrient-rich digestate. The biogas can then be used as a renewable energy source for various applications, while the digestate serves as a valuable fertilizer.

Key Components of a Biogas Plant: Digester: This is the core component where anaerobic digestion takes place. It's a tank, often airtight, where microorganisms break down the organic matter. Feedstock: Organic materials like animal waste, agricultural residues, food waste, and sewage sludge can be used as feedstock for biogas production. Biogas: The gaseous product of anaerobic digestion, mainly composed of methane (CH4) and carbon dioxide (CO2). Digestate: The remaining material after digestion, rich in nutrients and can be used as a fertilizer.
