Heterogeneous catalysis is essential for sustainable chemical manufacturing, requiring a multidimensional approach that integrates atomic-level design with planetary impact considerations. The current linear economy model is unsustainable, as over 99% of chemicals exceed planetary boundaries. Sustainable catalytic technologies must prioritize sustainability metrics, industry partnerships, and circular economy principles. Chemical engineering has historically enabled large-scale production of essential products, but reliance on fossil resources has caused environmental and health issues. The Anthropocene era is marked by human-induced environmental changes, making limiting global warming to 1.5°C a major challenge. Heterogeneous catalysis will play a key role in transforming renewable feedstocks like CO₂, water, and biomass into sustainable chemicals. Chemical engineers must consider environmental, social, and economic dimensions of sustainability. Atomic-scale engineering has enabled new materials for CO₂ conversion, such as Pd-In₂O₃-ZrO₂ and Zn-ZrO₂, which show industrial potential. Single-atom catalysts offer uniform structures that enhance scarce metal utilization. However, challenges remain in controlling metal environments and reaction dynamics. Advancements in characterization techniques, including machine learning, are crucial for understanding catalyst behavior. Reactor design and mass-transport considerations are vital for improving electrocatalytic devices and plastics recycling. Life-cycle assessments help evaluate environmental impacts and guide sustainable process design. Decentralized ammonia synthesis using solar-powered electrocatalytic nitrogen reduction shows feasibility in densely populated areas. Implementing sustainable catalytic processes requires collaboration between academia and industry, as well as public awareness. Machine learning can accelerate data analysis and improve catalyst synthesis reproducibility. A circular economy model is needed to replace the traditional 'take-make-dispose' model. Sustainable chemical processes must integrate renewable resources, decarbonized energy, and circular economy principles. Achieving this requires educational initiatives and policy development to promote sustainable practices. Heterogeneous catalysis is a crucial tool for a sustainable chemical industry, but its success depends on multidisciplinary collaboration and a shift in mindset toward sustainability.Heterogeneous catalysis is essential for sustainable chemical manufacturing, requiring a multidimensional approach that integrates atomic-level design with planetary impact considerations.
