Green Chemistry in the Circular Economy: Catalytic Innovations and Industrial Decarbonization Pathways

Abstract

The transition to a circular economy necessitates innovative strategies for sustainable chemical production and industrial decarbonization. Green chemistry, with its emphasis on atom economy, renewable feedstocks, and environmentally benign processes, has emerged as a cornerstone in achieving these objectives. This review explores recent catalytic innovations that enhance reaction efficiency, reduce waste, and enable the valorization of industrial by-products within circular systems. Key advancements in heterogeneous and homogeneous catalysis, including photocatalytic and electrocatalytic approaches, are analyzed for their potential to decouple chemical manufacturing from fossil-based carbon sources. Furthermore, the study examines industrial decarbonization pathways, highlighting the integration of green catalytic processes into large-scale operations and the role of process intensification in minimizing energy consumption and greenhouse gas emissions. By synthesizing current research and case studies, this review underscores the synergies between green chemistry principles and circular economy frameworks, offering insights into scalable solutions for sustainable industrial transformation. The findings provide a roadmap for policymakers, researchers, and industry stakeholders aiming to align chemical innovation with climate and sustainability goals.
