Special Issue Information

Dear Colleagues,

Millions of tonnes of plastic are produced per year globally with approximately 50% of this plastic produced for single-use applications such as packaging and disposable consumer items, which means that much of this plastic quickly becomes waste. About 86% of the waste plastic in the United States is sent to landfills. However, with decreasing space and consequentially increasing costs of landfill usage, alternatives to landfills are currently being researched and developed.

Sending plastics to landfills can be especially detrimental for the environment as it takes many plastics hundreds, if not thousands, of years to degrade. Even biodegradable plastics may take considerable amounts of time to degrade as the rate of degradation depends on many physical factors such as ultraviolet light exposure, oxygen, and temperature.

This Special Issue will focus on waste plastic up-cycling, which is chemical recycling where the polymer is depolymerized and then repolymerized with the option to produce high value monomers, chemicals, fuel and liquid hydrocarbons. Waste plastic up-cycling has the main advantage of processing heterogeneous and contaminated polymeric waste without sorting and requires little or no pre-treatment.

We invite authors to submit manuscripts that will address the topics of waste plastic up-cycling; related catalysis, process & plant design, techno economic assessment, life cycle analysis, reduction to practice; the production of monomers, chemical intermediates/products, and refinery-like liquids; and the circular monomer–plastic economy.

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 papers will be 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 2000 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.
