In this paper, we propose a low-cost, easily deployable automated and selective disassembly and sorting system for EoL phones, consisting of three subsystems: an adaptive cutting system, a vision-based robotic sorting system, and a battery removal system. The system can process over 120 phones per hour with an average disassembly success rate of 98.9%, efficiently delivering selected high-value components to downstream processing. It provides a reliable and scalable automated solution to the pressing challenge of EoL phone disassembly.

However, understanding how CE can be applied to complex capital project delivery, both in theory and in practice, remains fragmented. To demonstrate potential strategies and their impact, we conduct a systematic scoping review and mapping of interdisciplinary literature on capital project delivery and the circular economy.

This paper provides a structured approach to improve the representation of CE in IAMs and guides their application in climate policy assessments. To this end, we first propose a framework to organize the multiple layers and policy dimensions involved in CE. We then review the current state of CE modeling in IAMs and identify critical gaps, including limited attention to policy mechanisms, lack of material-level granularity, and insufficient coverage of downstream and upstream supply chain sectors. Lastly, we identify priority areas for improvement, such as coupling IAMs with material flow and sectoral models, refining data and structural assumptions, and developing more coherent CE policy narratives. Together, these steps establish pathways for the scientific community to better integrate CE into IAMs and strengthen understanding of its role in global climate mitigation strategies.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"225 ","pages":"Article 108614"},"PeriodicalIF":10.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145261953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
