Energy Materials: A Circular Economy Approach emphasizes the engineering scalability of a circular economy approach to development and use of energy materials. It focuses on waste minimization and its valorization, recycling and reuse, and emerging sustainable materials and technologies. It offers a view of the eco-friendly energy materials and state-of-the-art technologies required for production of these materials in the process industry and manufacturing sectors. Covers fundamentals, concepts, and current initiatives within the circular economy Outlines technologies and materials with specific applications for energy systems and societal benefits Focuses on detailed aspects of process scale-up, kinetics, and application of circular economy in waste utilization and valorization Discusses technologies, processing methods, and production of materials related to fuel cells, carbon capture, catalysis, functional materials, nanotechnology, biofuels, solar energy, and fine chemicals Details topics related to synthesis and application of energy materials, their recycle, reuse, and life cycle. This book is aimed at researchers and professional engineers and scientists working in chemical, materials, energy, and environmental engineering, as well as materials chemistry.
