This second volume of the Handbook of Energy, Environment, and the Circular Economy focuses on Sustainable Resource Management at the intersection of energy systems, environmental chemistry, and circular materials. Building on the conceptual framework established in Volume 1, it provides an in-depth examination of key scientific and technological pathways that enable the transition from the linear economy to circular energy and material flows.The chapters address fundamental and applied aspects of environmental chemistry, water–energy interactions, plastics recycling, and emerging catalytic systems for sustainable chemical production. Emphasis is placed on understanding material cycles, process efficiency, and system integration across the energy, water, and industrial sectors. The chapters combine theoretical foundations with practical insights, highlighting state-of-the-art technologies, techno-economic considerations, and real-world implementation challenges.Authored by leading researchers from academia and international research institutes, this volume offers a balanced perspective that integrates chemical engineering, environmental science, and energy systems analysis. Richly illustrated and extensively referenced, it serves both as a comprehensive reference work and as a teaching resource for advanced undergraduate and graduate courses.This volume is intended for researchers, engineers, policy analysts, and decision-makers seeking scientifically grounded solutions for sustainable resource management within the broader context of the circular economy and global energy transition.
