The book provides a comprehensive overview of the technologies and processes involved in renewable energy generation, with a specific focus on their role in improving the circular economy. It offers all the necessary information and tools to help readers select the most sustainable renewable energy solution for different conditions. Exploring real-life examples, the book delves into the practical applications of the circular economy in the renewable energy sector. It takes a multi-faceted approach, examining the circular economy from various perspectives and incorporating methods such as lifecycle assessment, sustainability assessment, multi-criteria decision-making, and multi-objective optimization modes. Furthermore, the book explores the concept of blockchain, hybrid renewable energy models, technologies, and implementation. It also investigates the critical factors and key enablers that influence sustainable development in this field. By doing so, it not only facilitates the transition to a circular economy but also highlights the shift in recent research, trends, and attitudes towards a more scientifically grounded approach. The primary objective of this book is to compile research specifically focused on the circular economy in renewable energy. By providing researchers and policymakers in the energy sector with the necessary scientific methodology and metrics, it enables the development of strategies for a sustainable transition. This book serves as a valuable resource for students, researchers, and practitioners seeking to deepen their understanding of energy planning and the current and future trends of biofuel as an alternative fuel.

Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it’s based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

​This book describes the available technologies that can be employed to reduce energy consumption and greenhouse emissions in the steel- and ironmaking industries. Ironmaking and steelmaking are some of the largest emitters of carbon dioxide (over 2Gt per year) and have some of the highest energy demand (25 EJ per year) among all industries; to help mitigate this problem, the book examines how changes can be made in energy efficiency, including energy consumption optimization, online monitoring, and energy audits. Due to negligible regulations and unparalleled growth in these industries during the past 15-20 years, knowledge of best practices and innovative technologies for greenhouse gas remediation is paramount, and something this book addresses. Presents the most recent technological solutions in productivity analyses and dangerous emissions control and reduction in steelmaking plants; Examines the energy saving and emissions abatement efficiency for potential solutions to emission control and reduction in steelmaking plants; Discusses the application of the results of research conducted over the last ten years at universities, research centers, and industrial institutions.
