Sustainable catalysis: A holistic framework for lifecycle analysis and circular economy integration in catalyst design

This paper presents a holistic framework for advancing sustainable practices in catalyst design, emphasizing the integration of lifecycle analysis (LCA), recyclability, and circular economy principles. Catalysts are critical in numerous industrial processes, but their production, use, and disposal often lead to significant environmental impacts. The proposed framework advocates for LCA as a tool to assess and minimize these impacts across the catalyst lifecycle. It highlights strategies for enhancing recyclability through advanced material designs and innovative regeneration technologies, addressing challenges of cost and technical feasibility. Furthermore, the paper explores the integration of circular economy principles, showcasing closed-loop systems in industries like petroleum refining and semiconductor manufacturing. These systems demonstrate the potential for substantial environmental and economic benefits by recovering and reintroducing spent catalysts into production cycles. Recommendations for industries and policymakers include adopting lifecycle thinking, investing in advanced recycling technologies, and establishing regulatory and economic incentives. The framework provides actionable insights to guide industries toward sustainability while ensuring high-performance catalytic processes.
