With increased awareness of the circular economy, textile waste is considered valuable resources. Reusing clothing is considered the most sustainable waste management approach, as it retains product value better than redesign or remanufacturing. Consequently, the second-hand market is expanding significantly. While mechanical recycling of plastic-to-textile and chemical recycling of natural fiber and cotton/polyester blended textiles are currently prevalent, textile-to-textile recycling is expected to increase to fulfill closed-loop system regardless of fiber type. However, due to technical limitations in recycling, textile waste ends up being disposed of through incineration and landfill. These methods can enable waste to serve as a substitute for fossil fuels. Textile exhibits a higher calorific value than other waste during combustion, and methane emitted from buried textile can be converted into renewable energy. Therefore, incineration and landfill without energy recovery merely pollute the environment, making them the least favorable waste management options. This study provides valuable insights into sustainable and practical strategies by delineating the advantages and limitations of current disposal methods in fashion and textile industry.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 4","pages":"2183 - 2197"},"PeriodicalIF":3.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Cathode sheets with different mileage histories were evaluated for uniform degradation effects, whereas additional storage conditions, including ambient and high-humidity environments, were analyzed for localized degradation behavior. The findings indicate that uniform degradation had a minimal impact on separation efficiency, whereas localized degradation, especially under high-humidity conditions, significantly impaired separation due to the formation of spot-like deposits that increased interfacial resistance and promoted pulverization rather than delamination. Chemical analyses revealed that LiPF₆ decomposition, an electrolyte component, is the primary pathway for degradation under ambient storage, leading to HF acid formation, accelerating corrosion and deposit formation on the cathode surface. Samples stored at low temperatures (4 °C) exhibited reduced surface degradation and maintained an effective separation performance. These findings show that reducing moisture exposure and maintaining low temperatures are crucial for effective separation during recycling processes using electrical pulsed discharges.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 4","pages":"2723 - 2735"},"PeriodicalIF":3.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-025-02278-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
