Summary
The global drive toward energy efficiency and industrial decarbonization calls for innovative approaches to design, optimize, and integrate energy and resource systems. Process Systems Engineering (PSE) offers powerful methodologies for achieving these goals through systematic modeling, optimization, and integration of energy-intensive industrial processes.
This Special Issue aims to present recent advances in process systems engineering, energy efficiency, resource conservation, and low-carbon process design that support the transition to sustainable industrial systems. Contributions may include theoretical developments, methodological innovations, and practical applications that demonstrate energy and emissions reduction across industrial sectors.
Suggested topics include (but are not limited to):
· Process integration and optimization for energy and resource efficiency
· Carbon management and emission minimization in industrial processes
· Energy-water-waste nexus and cross-sector resource recovery
· Industrial symbiosis and circular resource utilization
· Multi-objective optimization for sustainability and operational performance
· Digital tools and data-driven approaches for low-carbon process design
· Life cycle and techno-economic assessment of energy-efficient systems
We invite researchers, engineers, and practitioners to contribute original research and reviews that advance the development of sustainable, efficient, and resilient industrial systems.
