We used 446 sampling transects on 170 beaches from Norway’s south-eastern, southern, western and northern coasts. Plastic weight and count were chosen as response variables in several linear models, with different explanatory variables included. Although the explained variance in plastic pollution did not lead to any meaningful insights regarding plastic distribution, other insights were gained. Measuring plastic pollution by weight or item count led to different correlations of predictor variables. There were significant regional differences in models, and some predictor variables clearly show different values depending on the region. Furthermore, geographical beaching patterns of different types of plastic debris along the Norwegian coast found in the literature were confirmed. The southern coast had the largest number of plastic items per sampling area, whilst the north displayed fewer but heavier items. Dividing the data by region seems to be desirable, but more samples per region are needed.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 11","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13762-026-07430-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132028","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}

Substantial variability in wastewater quality and pharmaceutical concentrations was observed prior to ozonation. VEN concentrations exceeded the predicted no-effect concentration (PNEC; 90 ng L<sup>−1</sup>) in wastewater from all WWTPs, while CBZ concentrations exceeded PNEC (500 ng L<sup>−1</sup>) at the medium- and large plants, indicating potential ecological risk under a conservative worst-case screening scenario. Ozonation reduced pharmaceutical concentrations below the applied PNEC-based risk thresholds, achieving CBZ removal below detection limits within 5 min. VEN concentrations were substantially reduced after 5 min and remained below the limit of quantification (5 ng L<sup>−1</sup>) at 10 and 15 min of treatment. In addition to pharmaceutical removal, ozonation significantly improved wastewater quality by reducing suspended particulate matter and chemical oxygen demand, while culturable bacterial counts decreased below detectable levels within 5 min.

As a result, EU sustainability strategies can be misleading and fail to address deep regional inequalities. This study proposes a novel, target-oriented evaluation framework that couples the CRITIC weighting method with the WERO methodology to assess the sustainability performance of the EU-27. The analysis is mainly based on Sustainable Development Goals (SDG) indicators data reported in the <i>Sustainable Development Report 2023</i>, complemented by data from additional sources where necessary. The methodological contribution lies in combining objective criterion weights, determined using the CRITIC method, with WERO's target-based evaluation mechanism, which measures countries according to their distance from predefined SDG thresholds rather than solely their relative performance. Unlike conventional multi-criteria decision-making (MCDM) models that merely track absolute performance, this approach shifts the paradigm toward strategic target proximity, evaluating countries based on their efficiency in meeting predefined sustainability thresholds. The empirical results expose a deeply entrenched regional divide, stratifying the EU into distinct frontier, convergence, and structural laggard clusters. By utilizing target-driven weights, the model successfully pinpoints precise systemic bottlenecks within structural laggards, such as acute poverty risks, lagging renewable energy integration, and electronic waste mismanagement. Consequently, the application of this methodological framework advocates the permanent abandonment of one-size-fits-all strategies in favour of a highly differentiated EU policy design. It outlines how primary financial instruments, including the Cohesion Fund and the Recovery and Resilience Facility, should be dynamically linked to specific institutional reforms and localized milestones. Ultimately, this framework transforms arbitrary country rankings into a precise, result-oriented roadmap for European integration.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 11","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132262","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 bioplastic samples were prepared by using water, vinegar, plasticizer (i.e., glycerin) and substrates (i.e., banana and potato peel bioplastics). The results showed that bioplastic prepared from banana peels was thinner and had greater water absorption, swelling percentage and elongation. Regarding biodegradability, potato peel bioplastic took more time than did banana peel bioplastic to biodegrade. Three factors, i.e., water, substrate and plasticizer concentration for elongation as one of the important parameters for bioplastic to prepare, therefore optimization of these parameters was done by central composite design of response surface methodology. Optimized elongation potential of banana peels bioplastic according to model depiction was achieved as 0.4 cm by addition of 53.36 and 2.5 ml of water and a plasticizer concentration, respectively with a substrate concentration of 20 g, after getting optimized elongation further tests including Young’s Modulus, thermal stability and water resistance were performed to test resilience of the bioplastic.

A multivariate framework combining principal component analysis (PCA), hierarchical cluster analysis (HCA), and quadratic discriminant analysis (QDA) was applied. Principal component analysis revealed three independent gradients governing food waste variability: carbon–nitrogen balance, solids concentration, and organic matter quality. Hierarchical cluster analysis identified two coherent substrate clusters broadly corresponding to carbohydrate-rich and protein- and lipid-rich profiles, with partial overlap between lunch and dinner wastes. Quadratic discriminant analysis demonstrated high discrimination accuracy ( > 95%) between service types, confirming their influence on physicochemical composition.
