Advanced Carbon Conversion and Utilization Technologies for Sustainable Industrial Chemical Production

Abstract

The mitigation of anthropogenic carbon dioxide emissions has become a critical priority for sustainable industrial development. Carbon conversion and utilization (CCU) technologies offer a promising pathway to transform CO₂ from a waste byproduct into valuable chemical feedstocks, fuels, and materials, thereby closing the carbon loop. This paper presents a comprehensive analysis of advanced CCU technologies with a focus on their integration into sustainable industrial chemical production systems. Thermochemical, electrochemical, photochemical, and biological conversion pathways are examined in terms of reaction mechanisms, catalyst design, energy efficiency, scalability, and techno-economic feasibility. Particular emphasis is placed on emerging catalytic systems, renewable energy coupling, and process intensification strategies that enhance conversion efficiency while reducing environmental impact. Life-cycle assessment perspectives are incorporated to evaluate the sustainability performance of CCU- enabled chemical processes. Key challenges, including high energy demand, catalyst degradation, and infrastructure compatibility, are critically discussed. The study demonstrates that advanced CCU technologies, when strategically integrated with renewable energy sources and industrial symbiosis frameworks, can significantly reduce carbon footprints while enabling circular chemical manufacturing. The findings provide valuable insights for researchers and industry stakeholders seeking scalable and economically viable pathways for carbon-neutral chemical production.
