Special Issue Information

Dear Colleagues,

More than eight billion tons of plastic waste has accumulated worldwide over the past 50 years. The majority (80%) of the waste goes directly into landfills and 3% ends up in the oceans. At the current rate, we are heading towards more plastic than fish in the ocean by 2050. Plastics are persistent in the environment and degrade slowly (over a century), releasing fragments, microplastics, and toxic chemicals into our environment.

The overall goal of this Special Issue is to shed light on the area of plastic waste recycling. Topics of interest include (but are not limited to) advanced mechanical recycling, chemical recycling, biodegradable plastic material development, microplastic characterization/mitigation, characterization advancement for plastic waste, and recycling policy analysis.

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. Recycling is an international peer-reviewed open access quarterly 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 1400 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.

The recycling target for plastics is expected to increase Europe-wide from 22.5% to 55% by 2025, hence the relevance of incentive schemes and the need to reach conclusions about how to encourage families to recycle more. Following this objective, a pilot project was implemented and a virtual reward token called RECICLOS created to encourage recycling among families, using incentives and awards to improve recycling behaviour and a webapp prototype to register the recycled plastic. By the end of the 6-week pilot project, 1053 families were registered on the scheme, representing 10% of the targeted population in the pilot area of the county of Pla de l’Estany, Catalonia, Spain. The novelties were the introduction of a token, the gamification of incentives through raffles and lotteries, webapp-based direct communication with citizens, and feedback after collecting and registering the recycled material. The multidimensional aspects of recycling activities, their strong relation with human behavioural patterns, and the high demand for communication and interaction mean that mobile technologies find significant application in this field. The results show that people can be influenced and their recycling habits changed by means of varied, effective, and innovative incentive schemes. Full article

Title: Properties and re-useability of light fraction plastics mechanically separated from WEEE
Authors: Ossi Martikka
Affiliation: LUT University
Abstract: Only in the EU, electrical and electronic equipment market reached 8.9 million tonnes in 2017, with increase of 6.5% from the previous year. Almost 3.8 million tonnes of WEEE was collected in the European union during 2017. The challenge with the reclaimed plastics, that it is likely they contain currently restricted substances as persistent organic pollutants. In this paper, the feasibility and possibility of recycling and sustainably reusing the light fraction separated from WEEE plastics utilizing hydrocyclone separation, is investigated with regard to regulatory norms such as 2011/65/EU and 2019/1021 (EU).
