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":"2025-06-17","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}

Using the Cross-Sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) model and Dumitrescu-Hurlin panel causality tests, the analysis captures both short- and long-run interdependencies between EESG indicators and circular economy performance, as proxied by total WtE output. The results indicate that recycling efficiency, energy self-sufficiency, recycling innovation, and WtE consumption significantly enhance circular economy performance in the long term. Causal tests confirm bidirectional relationships between circular economy performance and both recycling efficiency and energy self-sufficiency, underscoring mutual reinforcement between front-end recovery and energy resilience. WtE consumption shows a unidirectional effect on circular economy performance, driven by immediate energy needs and waste diversion. Circular economy performance also Granger-causes improvements in recycling innovation and environmental regulation, suggesting that strong circular outcomes may catalyze downstream innovation and policy development.

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.

Specifically, the willingness to adopt two selected circular eco-innovations was assessed through face-to-face interviews involving a sample of 211 olive growers in Apulia region (Italy). The two tested circular eco-innovations consist of the use of olive pomace digestate as soil conditioner/fertilizer and the use of reclaimed wastewater for irrigation.

Findings revealed that farmer’s cognitive characteristics, particularly environmental risk awareness, play a key role in the path of adoption.

The analysis focused on data from 2019, avoiding distortions associated with the COVID-19 pandemic.
