​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.

This book describes improvements in the iron and steel making process in the past few decades. It also presents new and improved solutions to producing high quality products with low greenhouse emissions. In addition, it examines legislative regulations regarding greenhouse emissions all around the world and how to control these dangerous emissions in iron and steel making plants.
A circular and environment-friendly economy could displace the linear economy as it is in use around the world. This would involve enlarged life cycles for products, and an increase in the efficiency of electric and electronic devices. The generation of new materials will be essential, as well as materials recycling or conversion after use. This book discusses new ways of production, management, recycling and conversion of new and regular materials. Keywords: Microplastics, Lignocellulose-Based Materials, Food Packaging, Biorefinery, Solar Energy, Reused Materials, Recycling of Plastics, Biopolymers, Composites, Polymeric Systems, CO2 Capture, Anticorrosive Polymeric Coatings, Metallic Structures, Scrap for New Steel, Nanomaterials, Waste from Electronic Components, Future of Cars, Raw Materials, Biomaterials, Bioeconomy, Circular Bioeconomy, Polymeric Electrolytes, Fuel Cells.
Numerous laws – including the Green New Deal – have been proposed or passed in cities, states, and countries to transition from fossil fuels to 100% clean, renewable energy in order to address climate change, air pollution, and energy insecurity. This textbook lays out the science, technology, economics, policy, and social aspects of such transitions. It discusses the renewable electricity and heat generating technologies needed; the electricity, heat, cold, and hydrogen storage technologies required; how to keep the electric power grid stable; and how to address non-energy sources of emissions. It discusses the history of the 100% Movement, which evolved from a collaboration among scientists, cultural leaders, business people, and community leaders. Finally, it discusses current progress in transitioning to 100% renewables, and the new policies needed to complete the transition. Online course supplements include lecture slides, answers to the end-of-chapter student exercises, and a list of extra resources.
Carbon intensive industries are at a crossroads. Long-term manufacturing plans using pyrometallurgical processes all include decarbonization levers: we must solve the problem of fossil-based reduction and fossil-based power generation processes for metals production. This collection explores innovative and diverse strategies for the enablement of low carbon industries in the high-temperature metals and materials processing fields. In particular, the following processes are investigated: · Electrolysis and electrification of metallurgical processes · High-temperature electrolytic routes for metal and alloy production · Use of hydrogen and other alternative non-carbonaceous reducing agents · Biofuels and other non-fossil reagents for metallurgical applications · Direct and indirect use of solar energy in high-temperature processing · Energy efficiency and waste heat recovery concepts applied to pyrometallurgical operations
This textbook explores the production of pig iron, covering the first part of the steel production process, known as ironmaking. Divided into seven chapters, it discusses the following topics: raw materials for steel production (coking coal, iron ore, slag-forming agents and fluxes, scrap, ferroalloys and pre-reduced materials), the sintering process (used to prepare the burden for the blast furnace), the pelletizing process (used to agglomerate the fine iron ores), the production of coke (the main reductant in the ironmaking process), the production of iron by reduction with gas (an alternative to the blast furnace) and the production of pig iron in the blast furnace (which is used in more than 65% of steel production worldwide). Specially conceived for graduate and undergraduate courses, this book is based on more than 30 years of teaching experience in courses for undergraduates, graduates (master and Ph.D.) and industry professionals (technicians). It explores the recent trends in the iron- and steelmaking process (which might used in the future production of steel), and features 55 worked exercises and real-world problems to complement of the theoretical sections of the text.
