Special Issue Information

Dear Colleagues,

The concept of critical material was created by the related expert commissions of the European Union in 2011. Since then, the number of identified critical materials included in the lists published every three years has been increasing. Metals occupy a major part of those lists, since many hold significant importance for key sectors in the European economy, are hardly replaceable, and have highly threatened supply. It is crucial to invest in the creation and development of sustainable technologies to reuse and recycle metals from end-of-life devices, residues, gaseous and liquid effluents, wastes, and scraps to effectively establish a circular economy and protect the future of the planet and all living species.

In recent years, hydrometallurgy has been playing a key role in the sustainable recycling of metals from several secondary sources. Hence, an updated state of the art of emerging hydrometallurgical technologies collected in a Special Issue is of great value.

This Special Issue welcomes critical reviews, original research, and case study articles dealing with innovative and emerging hydrometallurgical trends to efficiently and selectively recycle metals from secondary sources. Fundamental and applied investigations on hydrometallurgical methodologies would be highly appreciated and may also include solvometallurgical and biological approaches.

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.
