Fiber-reinforced polymer (FRP) has been gaining attention as an alternative to steel and aluminum in construction, automotive, and pipeline applications due to its exceptional high-performance properties. However, the environmental implications of FRP remain a concern, predominantly due to energy-intensive production processes and end-of-life (EoL) challenges. This review offers a comprehensive, cross-sectoral analysis of life-cycle assessment (LCA) findings on FRP, highlighting sector-specific drivers, environmental trade-offs, and methodological limitations. Although use-phase benefits, such as reduced emissions and lower maintenance costs, are well documented, they are often offset by the high embodied energy and underdeveloped recycling infrastructure. Existing LCA studies have emphasized climate impacts, while underrepresenting various indicators, including human toxicity, resource depletion, and circularity. Methodological limitations, such as generic datasets, a lack of performance-based functional units, and simplified EoL modeling, compromise comparability. Mechanical recycling often yields low-quality output with reduced performance, limiting reuse in high-value applications, whereas thermal and chemical methods face challenges in energy and scalability. Future efforts must prioritize standardized LCA methods, region-specific background datasets, circular economy integration, and advanced recycling technology to realize the full sustainability potential of FRP. A strategic framework is necessary to enable the widespread use of FRP as a viable, low-carbon alternative in a net-zero future.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"28 ","pages":"Article 200294"},"PeriodicalIF":6.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145466403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the mandatory food waste accounting in the European Union (EU), accurate FLW quantification becomes relevant. In this study, a systematic literature review of FLW quantification research within the EU agri-food chain was done. The information was synthesised and coded to identify definitional and methodological differences across studies and common FLW quantification frameworks – the Food Loss and Waste Accounting and Reporting Standard and the EU delegated decision 2019/1597. In addition, limitations outlined in the studies were synthesised to identify aspects limiting the credibility of the quantification procedure and applicability of the FLW data. Our findings indicate significant variability in research methods, representativity and scope across studies. Results show that food service and households are the most studied stages of the food supply chain, with questionnaires being the most used method. Unrepresentative sample, lack of accurate data and self-reporting error emerged as major limitations in the analysed studies. Studies also highlight economic and environmental considerations beyond mass estimates of FLW, and consideration of the agricultural production (pre-harvest/pre-slaughter and harvest/slaughter) stage in FLW quantification.

However, in academia and industry, the focus is mainly on the conceptual, economic, or logistical implementation at a high level. At the product level, conducting a precise technological feasibility study and evaluating circularity strategies in different areas is crucial to facilitate the transition towards resource optimization and waste reduction. In this context, this study proposes a debonding-on-demand (DoD) of an innovatively designed polymer sandwich structure consisting of a lower-melting temperature additively manufactured polypropylene (PP) honeycomb core structure and a higher-melting temperature glass fiber prepreg embedded in a PP matrix. The innovatively developed design allows for disassembly, recycling and reassembly of the sandwich structure. Trough the additive manufacturing process, load path adaption, optimization, and adjustment of varying material properties is effortless realizable.In addition, the manufacturing process is supported by different service-life simulations. Based on primary data, a new, innovative, and comprehensive assessment of manufacturing, performance, cost, and sustainability is performed. With the collected manufacturing data, a disassembly index was developed to evaluate multi-component products. The results demonstrate the potential of customizable, additively manufactured sandwich structures based on thermoplastic materials. The newly developed debonding mechanism and the thermo-mechanical recycling enable the reuse of the core material with comparable properties. The proposed multi-domain-based disassembly index is a comprehensive tool to evaluate the feasibility of products or material combinations after their useful life and can support the transition to a more data-driven circular engineering approach.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"28 ","pages":"Article 200296"},"PeriodicalIF":6.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145417414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by investigating these conflicts within the Dutch potato and coffee supply chains using a mixed-methods approach that integrates qualitative surveys and the Analytic Hierarchy Process. Potato farmers strongly favored economic goals over environmental ones, prioritizing primary sales revenue and soil quality, which led to composting and feed pathways. In contrast, processors adopted a more balanced perspective, focusing on profit, by-product revenue, and energy and water efficiency, favoring food ingredient pathways. Coffee growers and processors assigned similar weight to economic and environmental domains but differed significantly on specific objectives, such as raw material cost versus subsidies and soil quality versus wastewater demand. These differences influenced their distinct approaches to food ingredient valorization. Our findings demonstrate that actor-specific priorities critically shape valorization pathway selection and overall supply chain configuration.

However, the practical operationalization of cascading – where resources are sequentially utilized across multiple CBMs to maximize their residual value – remains insufficiently explored, particularly in the textile and clothing (T&amp;C) industry. This sector, marked by high resource consumption, short product lifespans, and significant environmental impacts, presents unique opportunities to slow resource loops and enhance value creation. This study systematically reviews 45 academic articles to examine how cascading is operationalized within the T&amp;C sector. Seven archetypes of cascading are identified, encompassing interactions within and between inner loops (e.g., rental, repair, reuse), outer loops (e.g., remaking, recycling), and open-loop applications across value chains. Using cascade chain theory, these practices are mapped onto four guiding principles: appropriate fit, augmentation, consecutive relinking, and balancing resource metabolism. The analysis reveals key enabling factors for effective cascading, including advanced sorting technologies, digital and physical tracking systems, circular design, life extension strategies, supply chain coordination, supportive policies, eco-material substitution, and innovative recycling techniques. Despite these enablers, scaling cascading operations is hindered by infrastructural limitations, market and safety challenges, insufficient local processing capacity, and regulatory barriers.
