Special Issue Information
Dear Colleagues,
Global urbanization and economic growth are driving solid waste generation to soar at an unprecedented rate, with annual global waste production projected to reach 3.4 billion tons by 2050. The current linear management model of “collection–transportation–disposal” not only consumes vast amounts of land resources but also leads to severe greenhouse gas emissions and environmental pollution. Consequently, establishing an efficient, circular waste management system has become an urgent global priority. The core challenge lies in whether technological innovation can transform waste from an “environmental burden” into an “urban mineral” while meeting growing treatment demands—all without exceeding the Earth's ecological boundaries.
Against this backdrop, the selection and application of cutting-edge technologies will play a decisive role. A series of disruptive technologies are emerging, ranging from AI-driven intelligent sorting robots and efficient bioconversion techniques, such as anaerobic digestion, to thermochemical processes that convert waste into high-value chemicals or fuels. However, the successful deployment and scaling of these technologies depend not only on their technical and economic viability but also critically on public awareness, acceptance, and behavioral cooperation. For instance, residents' precise sorting and disposal are prerequisites for intelligent recycling systems, while community acceptance of waste-to-energy facilities directly determines project siting and implementation.
We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.
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.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 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.
