Special Issue Information

Dear Colleagues, 

Plastics are an integral component of our modern lives due to their wide range of applications in households and industry. There is an increasing interest in the use of plastics as raw materials due to their ease of handling, transparency, and cost effectiveness. The quest for circular and sustainable approaches to material recycling is one of the most demanding for several reasons. However, there have recently been several breakthroughs in the reuse and recycling of materials.

Depending on the method used, polymer waste recycling can be classified as mechanical, chemical, or biological. For example, polymer waste from thermoplastics, thermosets, and elastomers of polymeric materials is not very degradable, thus requiring mechanical recycling. Polymer materials include polyethylene terephthalate, polyethylene, nylon, polyvinyl chloride, polypropylene, polycarbonate, polystyrene, polyurethane rubber, composites, and polymers, and are often found in the electronics and semiconductor industries, among others.

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. Polymers 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 2700 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.

This paper deals with the recovery of plastic fractions from waste discarded by an industrial composting plant that processes the organic fraction of municipal solid waste. Polymeric fractions (PE, PP and PET) were sorted from this discarded waste using a NIR separator. The polymeric fractions were then washed to remove residual contaminants and characterized with the aim of assessing their composition. A process of pelletizing and injection molding suitable for producing specimens made of 100% of these recovered materials was set up. The tensile strength and stiffness, as well as the microstructure of the recycled plastics, were investigated. The mechanical features of samples fully made of recycled PE and PP were like those characteristic of virgin polymers. Samples made of PET did not show completely satisfactory properties, as they displayed rather poor elastic modulus and ductility. Full article
