Pioneer of the biogas industry Carbotech Gas Systems GmbH was founded from Bergbau-Forschung GmbH. That is why we can look back on more than 60 years of experience in developing, engineering, and manufacturing gas processing and gas generation plants. Carbotech Gas Systems GmbH is the specialist for industrial gas purification and gas production of various biogenic and technical gases. With innovative technologies, we make an active contribution to CO2-neutral energy generation. The pressure swing adsorption process (DWA, “Druckwechsel-Adsorptionsverfahren”) developed and patented by Carbotech, is simple and impresses with its low energy requirements. Thanks to the continuous development of the plants over the past three decades, DWA is now one of the most efficient treatment processes on the market. Carbotech plants have been in operation worldwide for many years.
