Biogas is produced by fermentation of organic waste and renewable resources (NAWAROS). The main components of biogas are methane (CH4) and carbon dioxide (CO2). Depending on the type of material used, biogas may also contain a significant amount of hydrogen sulfide (H2S). Furthermore, the biogas also contains nitrogen (N), oxygen (O2), ammonia (NH3), and water vapor/moisture. Wi.Tec sensors can accurately and reliably measure these components to control and regulate the biogas process.
