Special Issue Information

Dear Colleagues,

Circular economy and sustainability are becoming fundamental for society and industries, opening new unexplored opportunities for innovation and eco-design.

EU regulations and directives and Reach restrictions limit the panorama of products and processes, paving the way for different technological solutions, materials, and nanomaterials within the principles of green chemistry. For example, the plastic industry is under the spotlight due to environmental pollution from fossil-based plastics and limited feedstock availability. However, many other industrial compartments, such as textile and leather, face similar limitations and product restrictions.

This Special Issue of Materials aims to publish original research and review articles reporting environmentally sustainable solutions, materials, and nanomaterials for different applications and manufacturing compartments:

  • Polymer industry;
  • Textile industry;
  • Biobased polymers;
  • Agro-industrial waste recovery/recycling;
  • Alternative, catalytic processes for the substitution of petrochemical-derived materials with biopolymers;
  • Life cycle assessment and life cycle cost evaluation;
  • Innovation in the production chain and waste management;
  • Environmentally sustainable products and processes.

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. 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 2600 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.

Over 50 MioT of Waste Cooking Oil (WCO) was collected worldwide in 2020 from domestic and industrial activities, constituting a potential hazard for both water and land environments, and requiring appropriate disposal management strategies. In line with the principles of circular economy and eco-design, in this paper an innovative methodology for the valorisation of WCO as a rejuvenating agent for bitumen 50/70 coming from Reclaimed Asphalt Pavement (RAP) is reported. In particular, WCO or hydrolysed WCO (HWCO) was modified by transesterification or amidation reactions to achieve various WCO esters and amides. All samples were characterised by nuclear magnetic resonance, melting, and boiling point. Since rejuvenating agents for RAP Cold Mix Asphalt require a melting point ≤0 °C, only WCO esters could further be tested. Efficiency of WCO esters was assessed by means of the Asphaltenes Dispersant Test and the Heithaus Parameter. In particular, bitumen blends containing 25 wt% of WCO modified with 2-phenylethyl alcohol, showed high dispersing capacity in n-heptane even after a week, compared to bitumen alone (1 h). Additionally, the Heithaus Parameter of this bitumen blend was almost three times higher than bitumen alone, further demonstrating beneficial effects deriving from the use of WCO esters as rejuvenating agents.
