This work used correlative and automated microscopy to have a better understanding of
the internal components and structures of a smartphones. The objective is to see if there
is any potential that these techniques can be of extra value for the recycling of electronic
waste.
Parallel slices were made out of one smartphone to study the internal structure and
components of the phone. After, the same kind of smartphone was shredded and melted
to study the behaviour of the material after these processing steps under the microscope.
For this research, the SEM and the attached software Mineralogic by ZEISS were used
to provide visual and statistical data. The system proved to be e cient and accessible
in treating waste electronic material. That is to say that the components could be easily
identi ed and classi ed under a speci c name. In the case of electronic waste this is
either as an alloy or as a pure metal. To have a good understanding of the alloy, detailed
analysis by Bruker were often necessary. Precious and critical metals were located and
their internal relationships with other components was studied. Shredding showed how
these compositions crumbled into smaller fractions or kept together as a whole. This
helped for instance to understand how metals are discarded into waste streams during
pre-processing steps as being trapped within other metal fraction, ceramics and plastics.
The molten phone sections showed how the original composition of the di erent components
completely changed. During crystallization, new compositions are made completely
di ering from the original ones.
Mineralogic in association with Bruker proved to be a valid system. However, it was
suggested to segment the sample in di erent phases based on optical microscopy and BSE
images. These phases could be more rapidly analysed under EDS without analysing all
pixel in a pre-determined grid analysis. This suggestion was mainly made to improve the
e ciency of automated microscopy on WEEE samples. Another issue to be faced in the
future is the sample preparation as it is very hard to generate representative sample for
this work. Combination with Ct-scans or other techniques is advised.

Water Electrical and Electronic Equipment Recycling: Aqueous Recovery Methods provides data regarding the implementation of aqueous methods of processing of WEEEs at the industrial level. Chapters explore points-of-view of worldwide researchers and research project managers with respect to new research developments and how to improve processing technologies. The text is divided into two parts, with the first section addressing the new research regarding the hydrometallurgical procedures adopted from minerals processing technologies. Other sections cover green chemistry, bio-metallurgy applications for WEEE treatment and the current developed aqueous methods at industrial scale. A conclusion summarizes existing research with suggestions for future actions.

Electrical and electronic waste is a growing problem as volumes are increasing fast. Rapid product innovation and replacement, especially in information and communication technologies (ICT), combined with the migration from analog to digital technologies and to flat-screen televisions and monitors has resulted in some electronic products quickly reaching the end of their life. The EU directive on waste electrical and electronic equipment (WEEE) aims to minimise WEEE by putting organizational and financial responsibility on producers and distributors for collection, treatment, recycling and rec

Global E-waste Management Strategies and Future Implications provides in-depth information about the global E-waste problem and the potential opportunities. Part 1 of this book starts with the introduction to the E-waste, sources, critical composition, and associated challenges & opportunities. Part 2 of this book further elaborates detailed overview of the current trends in E-waste management and existing treatment options (hydrometallurgy, pyrometallurgy, bioleaching and biohydrometallurgy) and its implications. The book also discloses the critical implications of the secondary pollutants on the environment and human health with special emphasis on the informal recycling practices in the developing nations. Part 3 deals with the existing regulations in developed and developing countries which are illustrated using case studies for effective understanding and to bridge the gaps between the developed and developing nations. Part 4 of this book includes scientific and technical information to get a better vision and understanding of the most advanced and innovative methods for E-waste management such as life cycle assessment (LCA), tax credit, extended producer responsibility (EPR), extended consumer responsibility (ECR) which is explained systematically with case studies. Part 5 of this book covers the best E-waste management practises, such as reduce, recycle, recover and reuse (4R) principles, circular resource management, value out of waste (VoW), solutions for smart cities, green product design etc., which is explained using the ideal case studies. Part 6 summarizes the transition towards sustainability.

This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Electronic waste occurs not just in the form of discarded computers but also as a scatter of information devices, software, and systems that are rendered obsolete and fail. Where other studies have addressed "digital" technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural, and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated "spaces" where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository. All together, these sites stack up into a sedimentary record that forms the "natural history" of this study. Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. By drawing on the material analysis developed by Walter Benjamin, this natural history method allows for an inquiry into electronics that focuses neither on technological progression nor on great inventors but rather considers the ways in which electronic technologies fail and decay. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys pulls together the far-reaching material and cultural processes that enable the making and breaking of these technologies.
