The long list of technological devices used in our day-to-day life and in modern industrial plants and diverse facilities relies extensively on the use of several metals. When those devices are no longer useful, they should be processed to recycle the involved materials since most of them are scarce, harmful to the environment, and valuable. This overall situation has led European Union to prepare lists of “critical raw materials” every 3 years since 2011. The latest one from 2017 identified 27 “critical raw materials,” 17 of which are metals. Recycling of metals from spent devices should therefore be considered as a top priority.
Several recycling plants worldwide are primarily based on pyrometallurgical techniques, but hydrometallurgy arises as a possible alternative; as lower temperatures are involved, it exhibits potential for extraction of any valuable co-metals, it can be adapted to both small- and large-scale operations, and liquid effluents are usually easier to handle than the volatile combustion emissions from the pyro-based recycling sites.
This Special Issue welcomes review, original research, and case studies articles, focusing on innovative and challenging hydrometallurgical techniques particularly developed to recycle end-of life devices containing critical metals, e.g., spent industrial catalysts and catalytic converters (SCC), waste electrical and electronic equipment (WEEE), spent batteries of different kinds, end-of-life fluorescent lamps, NdFeB magnets and similar devices, waste liquid crystal displays (LCD).

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Recycling is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
