Electronic Waste: Toxicology and Public Health Issues discusses the major public health concerns due to the presence of toxic chemicals that are generated from improper recycling and disposal practices of electronic waste (e-waste). This book highlights hazardous inorganic chemicals found in e-waste, including arsenic, cadmium, lead, mercury, gallium, iridium, and nanomaterials, also focusing on health issues related to the presence of BPA, styrene, and other plastic components and combustion products, while also identifying populations at special risk. To provide readers with potential solutions to this global problem, Dr. Fowler presents risk assessment approaches using chemicals, mixtures, biomarkers, susceptibility factors, and computational toxicology. He discusses how to translate the information gathered through risk assessment into safe and effective international policies. The final chapter is devoted to future research directions. This is a timely and useful resource for all those concerned with the health issues surrounding e-waste management and proper disposal, including toxicologists, public health and policy officials, environmental scientists, and risk assessors. Offers a well-researched, single authored book and draws attention to the need for better and more informed risk assessment and policymaking in this area Emphasizes the transference of electronic waste (e-waste) to developing countries where populations of concern include children working in recycling activities and impoverished groups with poor nutritional status and limited access to medical resources Reviews, in detail, the issue of exposure to chemical mixtures as a central feature of e-waste due to the presence of a number of organic and inorganic chemicals in modern electronic devices

The landscape of electronic waste, e-waste, management is changing dramatically. Besides a rapidly increasing world population, globalization is driving the demand for products, resulting in rising prices for many materials. Absolute scarcity looms for some special resources such as indium. Used electronic products and recyclable materials are increasingly crisscrossing the globe. This is creating both - opportunities and challenges for e-waste management. This focuses on the current and future trends, technologies and regulations for reusable and recyclable e-waste worldwide. It compares international e-waste management perspectives and regulations under a view that includes the environmental, social and economic aspects of the different linked systems. It overviews the current macro-economic trends from material demand to international policy to waste scavenging, examines particular materials and product streams in detail and explores the future for e-waste and its' management considering technology progress, improving end-of-lifecycle designs, policy and sustainability perspectives. To achieve this, the volume has been divided in twelve chapters that cover three major themes: holistic view of the global e-waste situation current reserve supply chain and management of used electronics, including flows, solutions, policies and regulations future perspectives and solutions for a sustainable e-waste management. The emphasis of the book is mainly on the dramatic change of the entire e-waste sector from the cheapest way of getting rid of e-waste in an environmental sound way to how e-waste can help to reduce excavation of new substances and lead to a sustainable economy. It is an ideal resource for policy-makers, waste managers and researchers involved in the design and implementation of e-waste.

An examination of the global trade and traffic in discarded electronics that reframes the question of the “right” thing to do with e-waste. The prevailing storyline about the problem of electronic waste frames e-waste as generated by consumers in developed countries and dumped on people and places in developing countries. In Reassembling Rubbish, Josh Lepawsky offers a different view. In an innovative analysis of the global trade and traffic in discarded electronics, Lepawsky reframes the question of the “right” thing to do with e-waste, mapping the complex flows of electronic materials. He counters the assumption that e-waste is a post-consumer problem, pointing out that waste occurs at all stages of electronic materials' existence, and calls attention to the under-researched world of reuse and repair. Lepawsky explains that there are conflicting legal distinctions between electronic waste and non-waste, and examines a legal case that illustrates the consequences. He shows that patterns of trade do not support the dominant narrative of e-waste dumping but rather represent the dynamic ecologies of repair, refurbishment, and materials recovery. He asks how we know waste, how we measure it, and how we construe it, and how this affects our efforts to mitigate it. We might not put so much faith in household recycling if we counted the more massive amounts of pre-consumer electronic waste as official e-waste. Lepawsky charts the “minescapes,” “productionscapes,” and “clickscapes” of electronics, and the uneven “discardscapes” they produce. Finally, he considers both conventional and unconventional e-waste solutions, including decriminalizing export for reuse, repair, and upgrade; enabling ethical trade in electronics reuse, repair, refurbishment, and recycling; implementing extended producer responsibility; and instituting robust forms of public oversight.

Currently, recycling of e-waste can be broadly divided into three major steps: (a) disassembly: selectively disassembly, targeting on singling out hazardous or valuable components for special treatment, is an indispensable process in recycling of e-waste; (b) upgrading: using mechanical processing and/or metallurgical processing to up-grade desirable materials content, i.e. preparing materials for refining process, such as grinding the plastics into powders; (c) refining: in the last step, recovered materials are retreated or purified by using metallurgical processing so as to be acceptable for their original using. Four topical areas are planned including one special session on the recycling of batteries. Papers in the following topics will be welcomed: Mechanical recycling of E-Wastes Recycling of plastics from E-Wastes Recovery of metals from E-wastes Hydrometallurgical recycling (leaching) of E-Wastes Combustion or pyrolysis of E-Wastes Life cycle and economic analysis for the recycling of E-Wastes

Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has catastrophic effects on humans and the environment. WEEE contains considerable quantities of valuable metals such as base metals, precious metals and rare earth elements (REE). Metal recovery from WEEE is conventionally carried out by pyrometallurgical and hydrometallurgical methods. In this PhD research, novel metal recovery technologies from WEEE are investigated. Using acidophilic and cyanide-generating bacteria, copper and gold were removed from crushed electronic waste with removal efficiencies of 98.4 and 44.0%, respectively. The leached metals in solution were recovered using sulfidic precipitation and electrowinning separation techniques. Finally, a techno-economic assessment of the technology was studied. This research addresses the knowledge gap on two metal extraction approaches, namely chemical and biological, from a secondary source of metals. The essential parameters of the selective metal recovery processes, scale-up potential, techno-economic and sustainability assessment have been studied.
