Dear Participants,
The Symposium on Circular Economy, Waste Management, and Sustainability (DASS 2025) will be held on October 30–31, 2025. The symposium aims to bring together scientists, educators, artists, and representatives from the private sector in a multidisciplinary environment, to share and discuss both theoretical and practical knowledge within a scientific framework. Abstract submissions are welcome.
All submitted abstracts will undergo a peer-review process. Authors who wish to publish extended versions of their full-text papers may submit them for further evaluation. After the editorial and peer-review process, selected papers presented at the symposium will be published in the Journal of Engineering and Basic Sciences (JOEBS) on April 15, 2026, in Volume 04. Additionally, selected papers will be published as an e-ISBN proceedings book following the symposium.
