Book excerpt: Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Available in PDF, EPUB and Kindle. Book excerpt: The high demand for advanced metallic materials raises the need for an extensive recycling of metals and such a sustainable use of raw materials. "Sustainable Utilization of Metals - Processing, Recovery and Recycling" comprises the latest scientific achievements in efficient production of metals and such addresses sustainable resource use as part of the circular economy strategy. This policy drives the present contributions, aiming on the recirculation of EoL-streams such as Waste Electric and Electronic Equipment (WEEE), multi-metal alloys or composite materials back into metal production. This needs a holistic approach, resulting in the maximal avoidance of waste. Considering both aspects, circular economy and material design, recovery and use of minor metals play an essential role, since their importance for technological applications often goes along with a lack of supply on the world market. Additionally, their ignoble character and low concentration in recycling materials cause an insufficient recycling rate of these metals, awarding them the status of “critical metals”. In order to minimize losses and energy consumption, this issue explores concepts for the optimization concerning the interface between mechanical and thermal pre-treatment and metallurgical processes. Such new approaches in material design, structural engineering and substitution are provided in the chapters.

This book was released on 2011-05-17 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although most strategic metal reserves are unlikely to run out over the coming decades the perception of scarcity of certain minerals and metals may lead to increased speculation and volatility in price and supply. Strategically important metals are vital to advanced manufacturing, low-carbon technologies and other growing industries and the Government should provide reliable information on potential resource risks in a coordinated and coherent way. The UK also exports large quantities of scrap metal and waste electrical and electronic equipment (WEEE), often to developing countries. This metal not only is a potential resource for the UK but it is also an example of the UK exporting its environmental problems elsewhere. There are also concerns about the illegal export of WEEE, which is often labelled as second hand equipment for re-use, and calls for safeguards to be put in place. Despite a rate of 90% (by weight) metal recycling in the UK, it is of great concern that some strategic metals are likely to be lost in the 10% not being recycled. The report recommends: Improving existing legislation to ensure companies implement requirements on reporting non-financial information, such as human rights and health and safety issues; an evaluation by the Government of the potential for introducing similar legislation to that in the US whereby companies are required to produce detailed reports on 'conflict minerals' that they use. This report also brings the alleged activities of large dealers on the London Metals Exchange to the attention of the Office of Fair Trading. Finally, the report looks at domestic extraction and says planning regulations should not unnecessarily restrict the use of significant potential reserves and that domestic mining could alleviate risks associated with sourcing metals from external supply monopolies. In parallel the Government has to invest in research to ensure that future domestic mining has the least possible environmental impact

This book was released on 2018-05-18 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. - Provides a one-stop reference for hydrometallurgical processes of metal recovery from WEEE - Includes methods presented through intended applications, including waste printed circuit boards, LCD panels, lighting and more - Contains suggestions and recommendations for future actions and research prospects
