Researchers currently lack a unified vernacular to study the many forms of circularity in cities. This review examines urban resource circularity strategies from the academic and gray literature to propose a typology of circularity based on the embeddedness of different practices in urban systems. We identify three complementary forms of urban circularity: industrial symbiosis, conventional waste management, and urban symbiosis. Urban symbiosis is distinct in that it leverages the spatial and social concentration unique to cities, creating opportunities for engaged city dwellers to actively shape circularity. Despite being utilized frequently in practice, urban symbiosis is critically undertheorized. By rigorously defining urban symbiosis, we provide a common language to discuss and synthesize disparate strands of literature on citizen-led urban circularity. Urban symbiosis, therefore, provides a potent lens for exploring and ultimately reimagining resource flows in cities. We propose an agenda for future research on urban symbiosis and envision it as a way for citizens to democratically shape more circular and just urban futures by exercising their “right to the sustainable city.”</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"227 ","pages":"Article 108743"},"PeriodicalIF":10.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145730841","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}

Since it is unclear whether such advances can offset expected material shortages, we assess whether global reserves, production, and recycling capacity can support the projected battery growth.

Bioleaching, a natural process utilising microorganism to mobilise metals from solid mineral matrices, has become increasingly popular as a sustainable and economically attractive alternative to conventional mining of minerals, particularly for low-grade ores and waste-derived feedstocks. The attractiveness of bioleaching lies in low environmental impact and high efficiency, even at low metal concentrations. This review explores different metal-bearing secondary materials containing critical, precious, and rare earth elements (REEs) as potential feedstocks for bioleaching. It traces the evolution of bioleaching from natural ore processing to its growing utility in urban waste valorisation within a circular economy framework. It compares bioleaching process in natural ores versus urban waste, while showcasing recent advancements toward commercial implementation.
