This study evaluates an extensive suite of analytical methods to characterize MSWI FA and APCA before and after water washing. Washing effectively removed soluble salts (e.g., NaCl, KCl), increasing stable phases like CaCO₃ and silicates, with variations dependent on ash origin and phase solubility. Washing also reduced particle size variability, yielding more uniform distributions. Chemical analyses demonstrated portable X-ray fluorescence (PXRF) as a reliable, cost-effective alternative to ICP-MS for elements including Al, Ca, Cu, Fe, P, and Zn, though weaker correlations for Pb, Si, and S suggest the need for more precise methods. Automated mineralogy showed sample-specific phase distributions: rotary kiln (RK) ash contained abundant ultrafine, unclassified matrix that increased post-washing, while grate furnace (GF) samples were dominated by lime, gypsum, and Ca-Si-Al phases, with washing reducing Cl-bearing and gypsum phases and slightly increasing reacted silicates. The circular fluidized bed (CFB) sample predominantly contained lime, and Ca-Cl-O and related reacted phases, showing minimal changes after washing. Minor metals such as Zn and Cu appeared heterogeneously distributed, bound within discrete or embedded phases, whereas bulk elements (Al, Ca, Mg, Si, Na) were uniformly integrated into the matrix. The findings emphasize the importance of combining multiple analytical techniques to achieve comprehensive characterization of MSWI ashes, bridging rapid screening with detailed analysis.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"27 ","pages":"Article 200268"},"PeriodicalIF":5.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365865","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}

Biochar, on the other hand, is commonly used for soil enrichment and carbon sequestration, which typically lacks sufficient nutrient content to function as a standalone fertilizer. This review explores an integrated approach to struvite production by incorporating biochar and waste-derived resources, specifically, farm waste (rich in N and P) and industrial wastewater (rich in Mg). Surface-modified Mg-biochar functions both as a Mg source and an effective adsorbent, enhancing nutrient adsorption, struvite crystallization, and retention. The review highlights alternative nutrient sources, Mg-biochar preparation methods, nutrient recovery mechanisms on the biochar surface, and the agronomic potential of biochar-struvite composites. This review supports the principles of a circular economy by transforming waste into value-added, slow-release fertilizers. The resulting biochar-struvite composite offers a promising strategy for pollution mitigation, improved crop productivity and sustainable nutrient management.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"27 ","pages":"Article 200273"},"PeriodicalIF":5.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605216","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}

However, some challenges keep these businesses from switching from a 'take-make-dispose' linear economy to a closed loop with zero waste. In this strand, one such issue is related to the companies’ requirements to understand the level of circularity in their operations. Thus, this paper aims to develop a CE maturity framework for SMEs. The framework draws upon three main phases, encompassing a set of qualitative and quantitative methods. Phase I involves the planning efforts to determine the framework’s audience and scope; Phase II is the development stage concerned with identifying the current state of the art related to CE and developing the theoretical framework for SMEs; Phase III is associated with the framework’s evaluation process, in which an expert panel review was applied to guarantee its robustness and consistency. The work proposes the Circular Economy Maturity Framework (CEMAF), composed of five dimensions: <em>take, make, distribute, use</em> and <em>recover</em>. These dimensions are deployed in sub-dimensions measured with several maturity items and supported by objective evidence. The weighted average of results supported the development of a CE maturity index, enabling companies to benchmark with others. The overall contribution of the research is to introduce a framework for the literature that considers SMEs’ ofter-limited resources, helping practitioners to evaluate and manage CE, and allowing companies to reach higher levels of circularity.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"27 ","pages":"Article 200275"},"PeriodicalIF":5.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633507","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}

We integrated three dimensions to develop a risk assessment model: the probability of production disruptions, competition risk, and vulnerability, offering a holistic view of both supply- and demand-side risks. The results reveal that lithium hydroxide and LIB exhibit the highest supply chain risks, primarily due to concentrated production and widely dispersed demand. Countries such as Japan, South Korea, and the United States face elevated supply chain risks. Early adopters of low-cobalt technologies have somewhat mitigated risks by reducing their exposure to resource competition.
