Life Cycle Assessment (LCA) and the Material Circularity Indicator (MCI) are prominent for analyzing environmental performance and product circularity, respectively. This study compares these methodologies applied to a case of plastic parts made from virgin Polycarbonate + 10% Fiber Glass for smart electricity meters. Sensitivity analyses were conducted on the recycled content used and the final treatment of parts. Both methodologies are sensitive to recycled content usage. The best scenario (SA1-10) features 100% recycled content and full recycling of parts, while the worst scenario (SA2-1) uses 100% virgin content with all parts disposed of in landfills. The results highlight similarities and differences between the methodologies. MCI focuses on material source, life extension, and end-of-life treatment to measure circularity. LCA covers a broader range of impact categories, including resource use, human health, and ecosystem impacts, making it more comprehensive for environmental analysis. Both emphasize the importance of recycled content and end-of-life treatment, underscoring the benefits of recycling in reducing environmental impacts and enhancing circularity.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3777 - 3786"},"PeriodicalIF":2.7,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142452936","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}

The selection of technological strategies compatible with the reality of each location represents an essential role in the success and continuity of the operation of the facilities. The best strategy will result from combining different environmental, economic, social, and technical dimensions, confronted with the interests of the stakeholders and the legal and policy contexts. Due to the complexity of different criteria, alternatives, and interests, a Multi-criteria Decision-making (MCDM) methodology is recommended to ensure the quality of the decision-making process. This study presents a systematic review of publications that have applied multi-criteria analysis as a decision support tool for the selection of biowaste management strategies. The different stages of management are discussed separately, highlighting the change in paradigms over time. It was found that less than a hundred studies have addressed it so far, with Asia contributing to most publications. However, the timeline shows that the number of publications is increasing, with multi-criteria models representing great potential to support decisions at any individual management stage, from preventing food waste to using by-products. Integrated multi-criteria approach that combines all stages of biowaste management, however, is still scarce in the literature.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3324 - 3340"},"PeriodicalIF":2.7,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142452933","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}

Yet recycled plastic use remains low due to safety concerns, undesirable aesthetic, olfactory, and mechanical properties, mainly attributable to contaminants present in recyclates. Advanced treatment options for recovered polypropylene (PP) packaging and the impact of such treatments on the polymer are currently poorly documented. We investigated the effectiveness of hot/cold washing and hot air devolatilization treatments in removing volatile substances from residential post-consumer PP plastic waste to improve its scope of application and value and to assess possible side effects on mechanical and processing parameters. Cold- and hot-washed recyclates exhibited similar contaminant levels and most substances were removed within 7 h. The recycling procedure had no adverse effects on mechanical or processing parameters although reprocessing caused polymer degradation, indicated by decreasing viscosity, elongation at break, and tensile strength. Washing and hot air devolatilization treatment of plastic wastes improve their scope of application and value by enhancing mechanical properties and considerably reducing the amounts of odorous substances, but is often not suited to high-quality applications, such as packaging. The dominance of packaging waste and strict legislation on food-grade recyclate applications will make widespread recyclate use challenging since it represents the primary use of plastic. Recyclate must consequently be extensively utilized in non-food contact applications until advances in waste sorting, washing, and devolatilization yield less contaminated recyclates with improved properties.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3824 - 3837"},"PeriodicalIF":2.7,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-024-02085-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142453039","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}

LIBs contain a significant proportion (12%—20%) of graphite, crucial for their anode's electrode active material, sourced primarily through mining and synthesis. However, concerns arise as a few countries, notably China, Turkey, and Brazil, control over 78% of the world's natural graphite reserves, highlighting potential supply chain risks. In addition to that, synthesizing graphite is expensive, and with the ever-increasing demand for EVs, the prices are expected to increase even further. Recycling graphite from waste LIBs extracted from EVs and electronic devices could potentially be a secondary source of graphite. This recycled graphite source can mitigate supply chain risk, preserve natural resources, lower prices, and decrease environmental pollution. This comprehensive review examines various pretreatment techniques and methodologies for recycling graphite from waste LIBs. It also provides a comparative discussion on the purity and recovery of graphite, its challenges, and prospects in LIB recycling technologies. This review serves as a valuable guide for researchers seeking sustainable practices and recycling methodologies in the EV industry.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3341 - 3369"},"PeriodicalIF":2.7,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142453014","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}

Considering this, this study proposes an improved BPNN identification method based on Bayesian regulation optimization. To illustrate the performance of the proposed model, NIR spectroscopy data from 200 samples of plastic-containing additives were analyzed for four plastics: acrylonitrile butadiene styrene, polyamide, polypropylene, and polycarbonate/acrylonitrile butadiene styrene blend.
