Dear Colleagues,

Materials are designed and processed using primary resources and different transformation processes. These processes can be physical, chemical, mechanical, or a combination of all these. This is true for all classes of materials (metals, plastics, ceramics and glasses, composites, etc.). Energy is consumed, and releases to the environment may occur during these steps.

Materials must fulfil different specifications, each corresponding to application requirements. During their service life they must keep the level of the required properties as constant as possible. After use and age, they become wastes, which may be converted into new resources if recycling processes are involved.

Thus, materials must now also fulfil circularity requirements. This means that they must be designed to be sustainable from the cradle to the grave. Resources saving, reducing, reuse, and recycling must become prerequisites for materials’ circularity. This Special Issue is open to all contributions bringing innovations and new concepts in these fields.

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. Materials 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 2600 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.
