The region-specific reference diet (RRD), a culturally appropriate variant of EAT-Lancet Planetary Health Diet, has been recently proposed for China, but its role in promoting sustainable healthy aging remains unclear. We hypothesize that combining RRD with social determinants can enhance sustainable healthy aging and reduce health disparities. Using 2020 food consumption data from the National Bureau of Statistics of China (NBSC), we estimated provincial RRD adherence and its association with healthy life expectancy (HLE) and Green Development Index (GDI). Based on the data from NBSC, the social return on investment identified five core social determinants, pension coverage, telephone subscriptions, senior care workforce, physician access, and internet use, that significantly reduced the unexplained variance in sustainable healthy aging after adjusting for RRD. Scenario-based simulations were performed by comparing four conditions: (1) 2020 status, (2) 2030 projection, (3) RRD adoption alone, and (4) RRD combined with synergistic social determinants. The integrated strategy based on RRD yielded greater improvements in HLE and GDI compared to the 2020 status and 2030 projection, while also significantly reduced regional and gender disparities compared to all other three conditions. These findings underscore the limitations of dietary interventions in isolation and highlight the potential of a multi-sectoral strategy for advancing equal sustainable healthy aging. Future studies are warranted to assess the impact of RRD-based integrated strategy in sustainable healthy aging in real world, and validate the findings in other countries.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 49-62"},"PeriodicalIF":9.6,"publicationDate":"2025-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144842581","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}

Nonetheless, even if drastic steps are taken today to reduce the production of textiles, the textiles already in circulation eventually need to be disposed of or recycled. To capture these garments and increase the quantity of textile available for recycling, the European Union (EU) has mandated the separate collection of the textile fraction across member states from 2025. However, collecting textiles for recycling does not guarantee that the collected textiles are recyclable. This study explores the recyclability of textiles by analysing the anatomy of textiles (linings, disruptors, adornments, and fibre blends) in Denmark and applies these findings to forecast the material available to different recycling routes in 2025. This study finds that in Denmark, after initial collection and sorting, textile complexity will likely result in the incineration of 36 % of textiles sent to recycling streams, 53 % will require disruptor removal, and 11 % will be available to different recycling routes. When the recycling capacity for high-quality recycling is considered, only a minor part (<2 %) of textiles in the Danish market can result in high-quality fibre-to-fibre recycling. These results emphasize the importance of considering textile anatomy both when designing textiles and determining recycling pathways. Moreover, our findings underscore that the Circular Economy (CE) transition cannot rely on recycling alone; instead, it must invest in avoidance and reuse approaches in addition to improved sorting and pretreatment facilities within Europe to best utilize the textiles currently in circulation.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 127-142"},"PeriodicalIF":9.6,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865175","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}

In CR, 80 % of impacts were from ceramic tile production, while in GR, polymer components were most impactful, polypropylene accounted for 82 % of Fossil Depletion and polyester for 95 % of Ozone Depletion. Sensitivity analysis showed that substituting the module and filter layers' materials with alternative polymers in GR reduced Marine and Freshwater Ecotoxicity by over 70 %. The optimized GR scenario achieved 71 % lower normalized impacts than CR and performed better in 13 of 14 categories. The 30-years projection reinforced the GR's superior performance over time.
