However, previous fragmented case studies generally focused on special minerals or typical chemical reactions, while the lack of a comprehensive perspective on chemical transformations hampers the efficient cycling of iron resources. In this review, the primary chemical transformation networks for 36 iron-bearing minerals, consisting of raw/secondary minerals from Fe-O, Fe-S, Fe-Si and other systems present on the Earth, are systematically constructed for understanding the iron resource cycling. Moreover, according to the chemical conditions and practical applicability of the transformation maps, geological cycle, industrial application and waste recycling within the iron resource cycling are reviewed for guiding the further acquisition and reutilization of iron resources. Finally, we underscore the necessity for future endeavors to concentrate on investigating iron compounds in complex substance, predicting transformative principles and pathways via data science, and applying the theoretical networks on regulation of iron resource cycling.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"220 ","pages":"Article 108353"},"PeriodicalIF":11.2,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929605","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}

This study shows that two modifiers derived from the same waste plastic source (PET)—DOTP (N1,N4-(dioctyl)terephthalamide) and HETP (N1,N4-Bis(2-hydroxyethyl)terephthalamide)—exhibit opposite effects on asphalt properties, despite having nearly the same carbon footprint. DOTP improves elastic recovery in multiple creep recovery tests (MCRT), while HETP increases strain accumulation and reduces elasticity. Density functional theory (DFT) shows that DOTP’s molecular structure can disperse well in bitumen mixtures by binding to both polar and non-polar components. In contrast, HETP binds only to the binder’s polar sites, lacking adequate dispersion. This increases the risk of aggregation of polar compounds in the bitumen mixture, resulting in a more deformation-prone binder. A techno-economic analysis highlights trade-offs between sustainability and performance in industrial-scale synthesis.
