Alongside nationwide efforts to expand industrial capacity, primary manufacturing sectors are adopting more resource-efficient technologies. This transition is expected to shift industrial water consumption patterns, driving the need for improved treatment and reuse practices. This study investigates opportunities for water use, treatment, and reuse in the iron and steel sector through a review of academic and industry literature and interviews with industry representatives. It identifies key challenges in water and wastewater management and outlines the conditions under which innovative treatment technologies could be deployed. Based on these insights, the study presents a practical water management action plan. Furthermore, it assesses water quality targets across different process operations, evaluates existing treatment technologies, and highlights challenges and opportunities for improvement relative to future performance expectations. Although water is often perceived as a low-cost commodity, industry feedback suggests that improvements in water use and treatment efficiency are typically prioritized only when they also reduce energy use, carbon emissions, or costs. This study advocates for a direct two-way partnership between industry and research audiences to bring their attention toward sustainable industrial water use, treatment, and reuse.</div></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":"34 ","pages":"Article 100298"},"PeriodicalIF":4.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, laboratory experiments were conducted on MPs of polylactide (PLA), a bio-based and industrially compostable polymer, and polystyrene (PS), a conventional oil-based polymer, to investigate their degradation in marine water and sediments at low temperatures. After 3 months PLA incubation in marine water (6–8 °C), gel permeation chromatography/size exclusion chromatography (GPC/SEC) showed a 17 % reduction in molecular weight (M<sub>n</sub>) and increased polydispersity index in samples under combined abiotic and biotic hydrolysis. Scanning electron microscopy indicated a local surface collapse of PLA. Degradation was inhibited in samples under abiotic hydrolysis alone. No molecular-level degradation occurred in samples buried in oxygen-deficient, fine-grained sediment. A limited (0.02–0.08 %) weight loss of PLA was observed across all experiments. Polystyrene microplastics showed no signs of degradation during the experiments. Our findings suggest that in bottom sediments, where temperatures are low and oxygen is scarce, PLA undergoes limited surface erosion rather than bulk degradation. This leads to long-term persistence and gradual reduction in particle size. Therefore, improperly managed PLA waste may contribute to micro- and nanoplastic pollution in deep-sea environments.</div></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":"34 ","pages":"Article 100331"},"PeriodicalIF":7.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145576058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Wilcoxon test revealed no statistically significant differences between individual concentrations in the two SCs. This research utilized ultrasound-assisted emulsification-microextraction for analytes isolation and gas chromatography-mass spectrometry for detection (USAEME-GC/MS) to determine BTRs and BPs concentrations in KNP's water bodies. Among the 34.4 % of occurrences above the limit of detection, BPA, 5Cl-BTR, and UV-P were consistently found across all sampling points and campaigns. Two BTRs (1H-BTR, 4Me-BTR) and five BPs (BPC, BPCl2, BPE, BPG, BPM) were below detection levels in both SCs. The maximum concentrations for BTRs reached 1.537 μg/L (5Cl-BTR, SP2, SC2). BPA concentrations peaked at 7.753 μg/L (SP6, SC2), exceeding the EU's predicted no-effect concentration for freshwater (1.5 μg/L) in six instances across the KNP samples. These findings highlight the importance of targeted monitoring and management strategies in protected areas, which align with the EU Water Framework Directive objectives.

SHAP-based analysis was employed to interpret the model's output and clarify the contribution of each base learner to the final decision. It revealed that the most influential interactions affecting classification outcomes were those between BOD and DO, as well as between conductivity and pH. Meanwhile, the main contributors among the base learners were the deep learning models, particularly LSTM and MLP.
