TLDR
This study, using China as a case study, analyzes the environmental, economic, and social implications of e-waste recycling in the developing world and recommends more practical approaches to alleviate the increasing environmental disruption from improper e-Waste disposal.Abstract:
E-waste recycling has become a hotly debated global issue. This study, using China as a case study, analyzes the environmental, economic, and social implications of e-waste recycling in the developing world. More practical approaches, taking into account local economic and social conditions and the principles of Extended Producer Responsibility, are recommended to alleviate the increasing environmental disruption from improper e-waste disposal.read more

Levels and trends of PBDEs and HBCDs in the global environment: Status at the end of 2012
Robin J. Law,Adrian Covaci,Stuart Harrad,Dorte Herzke,Mohamed Abou-Elwafa Abdallah,Kim J. Fernie,Leisa-Maree Toms,Hidetaka Takigami +7 more
TL;DR: More data on temporal trends of BDE and HBCD concentrations in a variety of matrices and locations are needed before the current status of these compounds can be fully assessed, and the impact of regulation and changing usage patterns among different flame retardants determined.
Journal ArticleDOI
Waste printed circuit board recycling techniques and product utilization.
TL;DR: The physical recycling techniques, which efficiently separate the metallic and nonmetallic fractions of waste PCBs, offer the most promising gateways for the environmentally-benign recycling of this waste.

Electronic waste as a secondary source of critical metals: Management and recovery technologies
Arda Işıldar,Arda Işıldar,Eldon R. Rene,Eric D. van Hullebusch,Eric D. van Hullebusch,Piet N.L. Lens,Piet N.L. Lens +6 more
TL;DR: In this paper, the global state of electronic waste, its management and the latest technological developments in metal recovery from various streams of e-waste are discussed. And perspectives on electronic waste as a secondary source of critical metals are given, including printed circuit boards (PCB), hard disc drives (HDD) and displays.

Tracking the global generation and exports of e-waste. Do existing estimates add up?
TL;DR: The main objective of this study is to track the global transport of e-wastes by compiling and constraining existing estimates of the amount ofe-waste generated domestically in each country MGEN, exported from countries belonging to the Organization for Economic Cooperation and Development (OECD) MEXP, and imported in countries outside of the OECD MIMP.

Advancements in the treatment and processing of electronic waste with sustainability: a review of metal extraction and recovery technologies
TL;DR: A review on the science and engineering of both conventional and innovative separation and recovery technologies for e-wastes with special attention being given to the overall sustainability is presented in this article, where physical separation processes, including disassembly, density separation, and magnetic separation, as well as thermal treatment of the polymeric component, such as pyrolysis, are discussed for the separation of metals and non-metals from ewaste.

Present and long-term composition of msw landfill leachate: a review
Peter Kjeldsen,Morton A. Barlaz,Alix P. Rooker,Anders Baun,Anna Ledin,Thomas Højlund Christensen +5 more
TL;DR: In this paper, the long-term behavior of landfills with respect to changes in oxidation-reduction status is discussed based on theory and model simulations, and it seems that the somewhere postulated enhanced release of accumulated heavy metals would not take place within the time frames of thousands of years.

E-waste: An assessment of global production and environmental impacts
TL;DR: Miniaturisation and the development of more efficient cloud computing networks, where computing services are delivered over the internet from remote locations, may offset the increase in E-waste production from global economic growth and theDevelopment of pervasive new technologies.
Journal ArticleDOI
Global perspectives on e-waste
TL;DR: The Basel Ban, an amendment to the Basel Convention that has not yet come into force, would go one step further by prohibiting the export of e-waste from developed to industrializing countries as discussed by the authors.

Export of toxic chemicals – A review of the case of uncontrolled electronic-waste recycling
Ming Hung Wong,Shengchun Wu,Wenjing Deng,X. Z. Yu,Qian Luo,Anna Oi Wah Leung,Coby S.C. Wong,W. J. Luksemburg,A. S. Wong +8 more
TL;DR: It is obvious that the environment is highly contaminated by these toxic chemicals derived from the recycling processes, especially on tracking the exposure pathways of different toxic chemicals which may affect the workers and local residents especially mothers, infants and children.

Spatial distribution of polybrominated diphenyl ethers and polychlorinated dibenzo-p-dioxins and dibenzofurans in soil and combusted residue at Guiyu, an electronic waste recycling site in southeast China.
TL;DR: The crude processing of e-waste has become one of the major contributors of PBDEs and PCDD/Fs to the terrestrial environment and acid leaching and open burning emitted the highest concentrations.
