Q&A: Gas fermentation could be game changer for the circular economy

Central goals of the circular economy include closing material cycles, reducing waste, and permanently keeping raw materials in the economic system. Achieving this requires innovative technologies that open up new avenues for recycling. Gas fermentation is a promising technology; however, some aspects are still in the research phase. The biotechnological process uses exhaust gases such as carbon dioxide as feedstocks to produce valuable products and enable a new approach to industrial emissions.
