• 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.
Article Summaries:
- Gas fermentation is emerging as a potential breakthrough for the circular economy, which aims to close material loops, cut waste, and keep raw resources within the economic system. The biotechnology process captures exhaust gases-particularly carbon dioxide-from industrial emissions and converts them into valuable products such as biofuels, chemicals, and feedstocks. By turning waste gases into useful materials, the technology could reduce reliance on virgin resources and lower greenhouse‑gas footprints. However, the approach remains largely experimental, with most studies still in the research phase. Further development and scaling are needed before it can be widely adopted in industrial settings.
