Book Description
The high demand for advanced metallic materials raises the need for an extensive recycling of metals and such a sustainable use of raw materials. "Sustainable Utilization of Metals - Processing, Recovery and Recycling" comprises the latest scientific achievements in efficient production of metals and such addresses sustainable resource use as part of the circular economy strategy. This policy drives the present contributions, aiming on the recirculation of EoL-streams such as Waste Electric and Electronic Equipment (WEEE), multi-metal alloys or composite materials back into metal production. This needs a holistic approach, resulting in the maximal avoidance of waste. Considering both aspects, circular economy and material design, recovery and use of minor metals play an essential role, since their importance for technological applications often goes along with a lack of supply on the world market. Additionally, their ignoble character and low concentration in recycling materials cause an insufficient recycling rate of these metals, awarding them the status of “critical metals”. In order to minimize losses and energy consumption, this issue explores concepts for the optimization concerning the interface between mechanical and thermal pre-treatment and metallurgical processes. Such new approaches in material design, structural engineering and substitution are provided in the chapters.

Book Description
Over the past two decades, concern about the environment has brought with it a tremendous increase in recycling in the United States and around the world. For many, it has become not only a civic, but also a moral obligation. Long before our growing levels of waste became an environmental concern, however, recycling was a part of everyday life for many Americans, and for a variety of reasons. From rural peddlers who traded kitchen goods for scrap metal to urban children who gathered rags in exchange for coal, individuals have been finding ways to reuse discarded materials for hundreds of years. In Cash for Your Trash, Carl A. Zimring provides a fascinating history of scrap recycling, from colonial times to the present. Moving beyond the environmental developments that have shaped modern recycling enterprises, Zimring offers a unique cultural and economic portrait of the private businesses that made large-scale recycling possible. Because it was particularly common for immigrants to own or operate a scrap business in the nineteenth century, the history of the industry reveals much about ethnic relationships and inequalities in American cities. Readers are introduced to the scrapworkers, brokers, and entrepreneurs who, like the materials they handled, were often marginalized. Integrating findings from archival, industrial, and demographic records, Cash for Your Trash demonstrates that over the years recycling has served purposes far beyond environmental protection. Its history and evolution reveals notions of Americanism, the immigrant experience, and the development of small business in this country.

Book Description
"From the Foreword: " This book presents the results of a waste audit study for the metal finishing industry. The study, carried out for the State of California but applicable for metal finishers elsewhere, identifies opportunities for waste reduction available to the metal finishing industry and develops procedures that can be used by metal finishers to assess their own waste reduction opportunities. The study emphasizes technologies available to small- and medium-sized metal finishing plants. Typically, these shops operate a variety of physical, chemical, and electrochemical processes. Chemical processes include degreasing, cleaning, pickling, etching, coating, and electroless plating. Electrochemical processes include plating and anodizing. The tasks included in the study were: (1) selecting metal finishing plants to include in the study, (2) performing a waste audit at each selected plant, (3) developing recommendations for implementing waste reduction technologies at each audited plant, (4) discussing with facility representatives the feasibility of implementing the waste reduction recommendations, and (5) developing this waste audit study report and methodology. The study identifies three categories of waste reduction technologies that are available to metal finishers: (1) source reduction, (2) recycling and resource recovery, and (3) alternative treatment. The costs associated with implementing these technologies range from a few hundred dollars for making simple improvements in housekeepiing and minor process modifications to tens of thousands of dollars for installing recovery or treatment units. The benefits realized from implementing such improvements include reductions inmaterial purchase and waste disposal costs, as well as reduction in the liability

Book Description
Principles of Metal Refining and Recycling provides a self-contained introduction to the field of purification and recycling of metals. The scientific principles in the treatment of the various metals are the same. The importance of using a clean and properly alloyed metal is described in detail. The text covers thermodynamics, physical and transport properties, mixing, mass transfer and numerical models. It describes methods for removal of dissolved impurity elements, particles, and inclusions. It considers important aspects of the solidification process, remelting and adding of alloys. Recycling, future challenges and specific processes for each metal are discussed in detail. The book is a greatly extended update of the 1992 book Principles of Metal Refining by T. Abel Engh. It includes in particular the subjects of metal recycling, ferrous and non-ferrous metal refining, and metalloids like silicon.

Book Description
Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Book Description
"...This book is the best I have read on this subject of increasing importance in the past five years. Therefore, I recommend it strongly to a broad audience which is interested in and responsible for pollution prevention: students on environmental management courses, their lecturers, government administrators, industrial decision-makers and employees, consultants and members of NGOs. The honest impulse toward sustainable development underlying the work as a whole is encouraging for all of them." (Int. Journal of Environment and Pollution) "...Although this book necessarily focuses on many aspects of environmental law and industrial production in the USA, it contains much detailed information on pollution issued in the pulp and paper, pharmaceutical, electronics and commercial printing industries which will be of wider interest. It should prove useful to industrial chemists and engineers and indeed to all those with an interest in protecting our increasingly threatened environment." (Environmental Engineering)
