Special Issue Information

Dear Colleagues,

Research focused on sustainable waste treatment and technology is a rapidly evolving field. Advances that ensure both environmental protection and human health while simultaneously being both energy- and cost-efficient require continued innovation and cross-cutting interdisciplinary research. This is important to adapt to the new challenges that need to be faced, particularly with the expansion of artificial intelligence (AI).

This Special Issue aims to gather the latest developments in the field. Topics of interest may include:

  • Innovations in waste treatment and technology
  • Waste collection infrastructure: addressing limitations in current and aging systems
  • Waste disposal and reuse: strategies for sustainable end-of-life waste solutions
  • Energy management, integrating efficient energy use within waste systems
  • AI-driven challenges, including data quality, privacy, and economic viability

The Special Issue intends to collect research and review articles that provide the results of novel approaches and address important gaps in our knowledge. Submissions may deal with problems of practical relevance or focus on an experimental system of any size—large, small, pilot, or lab—and may pertain to developed, developing, or underdeveloped countries.

I look forward to receiving your contributions. 

Dr. Charikleia Prochaska

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Waste prevention is at the top of the EU Waste Framework directive hierarchy. With this in mind, this article considers the application of novel technologies in the Cultural Heritage Restoration and Conservation field through environmental and circular economy principles. While previous research has explored the use of wood waste for composite materials such as building insulation and concrete additives, the suitability of degraded historical wood waste for filament production and 3D printing has not yet been addressed. This article contributes to this topic by studying the PLA/wood composite, material composed of a polylactic acid (PLA) polymer matrix reinforced with wood particles, produced from degraded historical construction materials. The paper describes the process of producing filament from bio- and moisture-damaged pine beam and oak parquet, followed by the 3D printing of historical platband replica. Research methods include photogrammetry, filament machine construction, filament production and 3D printing. The machines settings used in the process: heater temperatures were set to 140 °C, 90 °C and 105 °C; servo speed was 33 s; spool tension was 12.5; winding speed was 24 RPM; and screw speed was 9.2 RPM. For material preparation, a mixture containing 25% pine and oak sawdust and PLA dust was processed to achieve particle sizes of 312 μm, 471 μm, and 432 μm, respectively. Filament production was carried out with diameters of 2.85 mm for the pine/PLA composite and 1.75 mm for the oak/PLA composite. Finally, replica samples were fabricated using 3D printing. The dual objective of this research was to develop the method of 3D printing from degraded historical materials and introduce it to restoration practice as a wood waste minimization technique. Perspectives for further study include the testing of 3D-printed construction materials in outdoor conditions, and pellet production to achieve a higher wood content, compared to the filament thread. The processes described are adaptable to a variety of materials and disciplines. Full article
