Polymer materials, such as plastics, rubber, and synthetic fibers, have excellent properties, including low density, easy processing, high performance, and multi-functionality, and they are widely used in various fields. However, the emergence of a large number of polymer wastes has posed serious challenges to people. Statistics show that approximately 8.3×109 t of plastic products have been produced globally, with a waste amount of about 6.3×109 t until 2015, while only 9% of this has been recycled. The environmental consequences of polymer solid waste are visible in the ever-increasing levels of global plastic pollution both on land and in the oceans. However, although there are important economic and environmental incentives for polymer recycling, end-of-life treatment options for polymer solid waste are in practice quite limited. Presorting of plastics before recycling is costly and time intensive, recycling requires large amounts of energy and often leads to low-quality polymers, and current technologies cannot be applied to many polymeric materials. For the prevention and control of waste polymer, it is essential to achieve the high-value utilization of waste polymer and improving scientific and technological innovation of plastic recycling. Recent research points the way toward compatibilization of mixed plastic wastes to avoid the need for sorting, chemical recycling methods with lower energy requirements and expanding recycling technologies to traditionally nonrecyclable polymers.
This Special Issue aims to explore the new recycling approaches for successfully recycling and utilization of waste polymer in terms of:
- Strategies for recycling mixed or contaminated polymer and minimizing the need for sorting through compatibilizer design;
- Improving chemical recycling efficiency and selectivity through catalyst development such as new low-energy catalysts; and
- Expanding recycling beyond thermoplastics;

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. Sustainability 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 2400 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.
