In recent decades, the development of science and technology has made human life easier and more comfortable, but has also built up environmental and economic pressure. It has increased the consumption of primary resources due to the high market demand and huge generation of waste during the production of products, as well as at the user end. In a world bank report published in 2018, global waste production was found to be responsible for about 5% of global emissions, with an output of 1.6 billion metric tons of carbon dioxide equivalent in 2016, and is expected to reach 2.6 billion metric tons by 2050. This has an adverse effect on nature, the climate, and living beings. The preservation of primary resources, fulfillment of market demand, and recycling of waste have also been addressed through the concept of the circular economy, which is based on the implementation of cleaner and sustainable technologies, and innovative business models with supported policies.
Scientists have developed many technologies for the recycling of different kinds of waste, e.g., mining/metallurgical, electronic, batteries, polymer, construction, plastic, food, and end-of-life products wastes. Despite the increasing number of recycling methods, further efforts are still required to devise innovations that provide more green, sustainable, and economical solutions for waste material treatment and give recycled materials a second life. In addition, the use of circular economy principles will be useful for the improvement of technologies and affect the overall economic and environmental impact.
This Special Issue invites both research and review articles focused on the broad range of waste (mentioned above) recycling options and their conversion into useful products using sustainable technologies. Studies on the circular economy and possible industrial solutions are also welcome. Possible themes of interest include, but are not limited to, the following:
- Sustainable processes for different kinds of waste (mentioned above) recycling;
- Novel methods for the separation of critical metals from secondary resources;
- Complexity, challenges, and risks in a circular economy;
- Circular economy models for waste recycling and their impact;
- Innovative processes for the extraction of REEs, Li, Ni, Co, Ga, In, etc., from end-of-life products;
- Application of biological processes to recover values from wastes and plastic/polymer waste degradation;
- Food waste treatment: biogas production and bioenergy sustainability;
- Hazardous waste remediation/detoxification;
- Current trends for construction and demolition waste management.

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.
