This book examines resource recovery and recycling from waste metal dust, including currently used techniques for waste processing and recycling and their applications, with practical examples and economic potentials of the processes. The focus of this book is on resource recovery by suitable treatments and techniques, including those of recovery by-products. For the first time, this book provides a comprehensive, one-stop reference including seminal principles and methods, the advantages and disadvantages of the processes discussed, and the economics of the technology. It will serve as a technical reference for working scientists and engineers, while serving as an educational reference to students studying the waste recovery of metals.

Resource recovery and recycling from millions of tons of wastes produced from industrial activities is a continuing challenge for environmental engineers and researchers. Demand for conservation of resources, reduction in the quantity of waste and sustainable development with environmental control has been growing in every part of the world. Resource Recovery and Recycling from Metallurgical Wastes brings together the currently used techniques of waste processing and recycling, their applications with practical examples and economic potentials of the processes. Emphasis is on resource recovery by appropriate treatment and techniques. Material on the subject is scatterend in waste management and environmental related journals, conference volumes and government departmental technical reports. This work serves as a source book of information and as an educational technical reference for practicing scientists and engineers, as well as for students. - Describes the currently used and potential techniques for the recovery of valuable resources from mineral and metallurgical wastes - Discusses the applications to specific kinds of wastes with examples from current practices, as well as eht economics of the processes - Presents recent and emerging technologies of potentials in metal recycling and by-product utilization

Pollution Control and Resource Recovery: Municipal Solid Wastes Incineration: Bottom Ash and Fly Ash explains the tools and technologies needed to characterize, stabilize, treat, recycle, or properly dispose bottom and fly ash. The public concern for the environmental impact of MSW incineration has increased significantly over the last 20 years, forcing manufacturers to develop, and plants to install and operate, high-cost advanced technology for pollution control. This book explores the latest information on this important topic. - Includes methods for characterization, stabilization, and solidification, treatment, and final disposal and recycling of bottom ash and fly ash - Provides the characterization of bottom ash and fly ash, the impact of moisture on the incineration process of municipal solid waste, and the weathering process of bottom ash in a landfill - Presents a brief, but rigorous, discussion of the constituents of fly and bottom ash, including polynuclear aromatic compounds and heavy metals

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.

The concept of a circular economy has been gaining increasing attention in recent years. Many of the sources of chemicals we have become reliant on are dwindling and the accumulation of waste products poses a serious environmental problem. By recovering resources from these waste materials, we can reduce our dependence on virgin feedstocks that may not be sustainable as well as reducing the quantity of material going to landfill sites. Incorporating different perspectives from a global authorship, this book aims to introduce systems thinking to the field of waste and resource management. The topics covered range from the use of biogeochemical processes in resource recovery to the application of engineered nanomaterials, with information relevant to both academia and industry. The broad range and cross-disciplinary nature of the topics in this book make it a valuable resource for those working in circular economy research, green chemistry and waste and resource management.

Holistic view of the current and future trends in electronic waste management, focusing on recycling, technologies, and regulations Management of Electronic Waste delivers a complete overview of all aspects related to the toxicity characterization of electronic wastes, along with other important topics including resource recovery, recycling strategies, biotechnological advancements, and current perspectives on waste generation and management. The book presents hazards associated with conventional recycling methods and highlights environmentally compatible economic approaches for resource recovery, along with eco-friendly strategies for management of electronic wastes. The high metallic content, heterogeneous and composite nature of e-wastes make them a rich secondary reservoir of metals. The book explores the valuable potential of e-waste and highlights the eco-friendly, sustainable technologies and recycling strategies for the profitable and effective conversion of waste to wealth. Written by a highly qualified and internationally renowned author, Management of Electronic Waste covers sample topics such as: Rise of e-waste generation paired with rising economies and mounting demand for electrical and electronic devices, with a country-by-country breakdown Status of e-waste management and recycling efforts around the world, along with key processes that drive e-waste recycling Macroeconomic trends between global demand and supply for metal resources and the transition of linear to circular economy Bioleaching, an economic and green approach for recovery of metals, from e-waste and other low grade metal repositories Different metallurgical approaches for extraction and recovery of resources from e-waste and their pros and cons Filling a gap on the understudied biotechnological recycling techniques and methods for mitigating environmental pollution caused by electronic waste, Management of Electronic Waste serves as an excellent guide on the subject for electronic waste producers, consumers, recycling industries, policy and law makers, academicians, and researchers.
