Electronic Waste

Book Description :

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

Book Description :

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

Book Description :

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.

Book Description :

Electronic and electric waste (e-waste), defined as end-of-life electronic products, including computers, television sets, mobile phones, transformers, capacitors, wires and cables, are a major global environmental concern. The crude recycling of e-waste releases persistent toxic substances, such as heavy metals, polybrominated diphenyl ethers (PBDEs), polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), and the environmental pollution and health risks caused by the improper disposal of e-waste has become an urgent issue. This book offers an overview of e-waste history, sources, and entry routes in soil, air, water and sediment. It also addresses e-waste transport and fate, bioavailability and biomonitoring, e-waste risk assessment, impacts on the environment and public health. In addition, it discusses the impact of e-waste on soil microbial community diversity, structure and function and reviews the treatment and management strategies, such as bioremediation and phytoremediation, as well as policies and future challenges. Given its scope, it is a valuable resource for students, researchers and scholars in the field of electronics manufacturing, environmental science and engineering, toxicology, environmental biotechnology, soil sciences and microbial ecology, as well as and plant biotechnology.

Book Description :

Hazardous waste has been defined as waste that is either in a solid, liquid, or gas form, which contributes significantly to serious irreversible or incapacitating reversible illnesses and poses a potential hazard to human health or the environment, depending on its quantity, concentration, and physical, chemical, or infectious characteristics. Hazardous waste risk assessment is a quantitative means of assessing the potential adverse effects of exposure on human health.Management of hazardous waste is a very important process for saving the environment and human life. Traditional and innovative techniques for the treatment and solidification of hazardous waste make for interesting research and study. Proper storage of hazardous waste ensures proper segregation of waste, separation of incompatible wastes, easy access to wastes, reasonable protection against vandalism, and adequate secondary containment. Hazardous wastes are generally stored in different modified containers, including drums and tanks. Prevention or minimization of hazardous waste and improving control methods are introduced as risk management options.Many countries, including developing countries, have taken steps in the right direction to minimize and manage hazardous waste, not only by cleaning up contaminated sites, but also by controlling and reducing the generation of hazardous wastes.
