Advances in Gas–Solid Separation for Solid Waste Recovery

Dear Colleagues,

With the global push toward sustainable development goals, the efficient recovery and treatment of solid waste have become key challenges in environmental engineering and the circular economy. Gas–solid separation technology, as a core process in solid waste sorting, recycling, and treatment, directly impacts resource recovery efficiency, secondary pollution control, and process economics. However, complex waste compositions, diverse separation scenarios (e.g., incineration, pyrolysis, mechanical sorting), and increasingly stringent environmental standards demand further innovation in gas–solid separation technologies.

This Special Issue aims to gather cutting-edge research and practical applications of gas–solid separation in solid waste recovery, covering fundamental theories, material development, process optimization, equipment innovation, and life-cycle analysis. We welcome original research articles, reviews, and case studies, with a focus on (but not limited to) the following topics:

• Novel Gas–Solid Separation Materials and Equipment: Design and optimization of high-efficiency dust collectors, cyclone separators, electrostatic sorting technologies, etc.
• Separation Mechanisms for Complex Waste Systems: Separation dynamics and mathematical modeling of wet, multi-component, or fine-particle waste streams.
• Low-Carbon and Intelligent Technologies: Energy-efficient processes, AI-driven separation system control, and digital monitoring.
• Secondary Pollution Control: Co-removal technologies for dust, heavy metals, or VOCs during separation.
• Engineering Applications and Interdisciplinary Integration: Industrial-scale case studies, economic analyses, and coupling with thermochemical conversion (e.g., pyrolysis/gasification).

Through this Special Issue, we hope to establish a platform for academic and industrial exchange, promoting innovation in gas–solid separation technologies and advancing solid waste recovery toward higher efficiency, precision, and sustainability.

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. Separations is an international peer-reviewed open access monthly 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.
