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
Available estimates suggest that the amount of used electronics is large and growing, and that if improperly managed can harm the environment and human health. Recent data suggests that over 100 million computers, monitors, and televisions become obsolete each year, and this amount is growing. These obsolete products are either recycled, reused, disposed of in landfills, or stored by users in places such as basements, garages, and company warehouses. This book explores the disposal of used electronics and the potential problems that can be averted through recycling or reuse.

Book Description
The consumption of technological products has increased in recent years owing to the modern industrial revolution, where people continue to acquire semiconductor device–based innovative hardware. However, this lifestyle may not be sustainable in the coming decades because it creates the global issue of electronic waste, caused by either mass-manufactured products or hardware that has worked in the past but is outdated now. This book presents accessible and organized literature on electronic waste recycling as an alternative route to engineering and realizing functional devices based on unusual material properties. It is a comprehensible study guide on the fundamentals of electronic waste usage and describes all aspects related to the state-of-the-art production and consumption cycles and the recycling of materials. The book explains the use of waste materials and the ways in which their unusual properties can be the basis of innovative devices for signal processing, sensing schemes, and reconfigurable operation.

Book Description
This book covers state-of-the-art technologies, principles, methods and industrial applications of electronic waste (e-waste) and waste PCB (WPCB) recycling. It focuses on cutting-edge mechanical separation processes and pyro- and hydro-metallurgical treatment methods. De-soldering, selective dismantling, and dry separation methods (including the use of gravity, magnetic and electrostatic techniques) are discussed in detail, noting the patents related to each. The volume discusses the available industrial equipment and plant flowsheets used for WPCB recycling in detail, while addressing potential future directions of the field. This practical, comprehensive, and multidisciplinary reference will appeal to professionals throughout global industrial, academic and government institutions interested in addressing the growing problem of e-waste. Covers principles, methods and industrial applications of e-waste and PCB recycling; Details state-of-the-art mechanical separation processes and pyro- and hydro-metallurgical treatment methods; Describes the available industrial equipment used and plant flowsheets for PCB recycling and addresses potential future developments of this important field.

Book Description
Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as e-waste. With advancements in the electronic world almost occurring on a day-to-day basis and increased availability of products to the public, it is not surprising to see a staggering increase in the generation of electronic wastes over the past decade. The e-waste now represents the biggest and fastest growing manufacturing of wastes with as high as about 40 million tons a year at the global level. All these thing leads to increase in E-waste generation in the country. Electrical and electronic equipment contain different hazardous materials which are harmful to human health and the environment, if not disposed of carefully. Due to the lack of awareness for e-waste recycling in emerging economies, innovation hubs and centres of excellence have not yet been established. This has leads to the requirement of a proper disposal and recycling system so that environmental pollution and health hazard is reduced. We have tried to give information in this book which will help in minimizing this ever growing problem. Today the electronic waste recycling business is in all areas of the developed world a large and rapidly consolidating business. This recycling is done by sorting, dismantling, and recovery of valuable materials. This diversion is achieved through reuse and refurbishing. This book aims at providing a thorough understanding and analysis of the E-Waste in the wake of evolving market dynamics. The book describes E-waste rules by Ministry of Environment and Forests. The book discusses the overview of the E-Waste Recycling along with their Classification, Composition, Recycling Process of different products and effects of E-waste on environment and human health. Also it contains suppliers contact details of plant & machinery with their photographs. The book covers E-waste Recycling- An Introduction, Overview of WEEE/E-Waste Management, Hazardous Materials in E-Waste, E-Waste Management System Specifications, Recycling of E-Waste, Recycling of Printed Circuit Board, Recycling of Liquid Crystal Display, Cell Phones Recycling, Battery Recycling, Computer Recycling, Restriction of Hazardous Substances Directive and Environmental Aspects. It will be a standard reference book for Professionals, Decision-makers, Engineers, those Studying and Researching in this important area and others interested in the field of E-Waste Recycling. Professionals in academia and industry will appreciate this comprehensive and practical reference book, due to its multidisciplinary nature.
