A major challenge for ECF production is achieving high-quality output in a cost-effective and low-carbon manner. In this study, a Composite-Feature-Multi-Objective-Interpretation (CFMI) framework based on machine learning (ML) was developed to simultaneously optimize energy consumption and CF surface roughness during ECF production. The results show that the eXtreme Gradient Boosting (XGBoost) model outperforms the other seven ML algorithms in predicting both energy consumption (RMSE = 50.39 kWh·t⁻¹, R² = 0.93) and CF surface roughness (RMSE = 0.30 μm, R² = 0.73). SHapley Additive exPlanations (SHAP) analysis identifies current density, temperature, and sulfuric acid concentration as primary factors influencing energy consumption, while deposition time, current density, and copper ion predominantly affect CF surface roughness. Moreover, SHAP-based feature clustering effectively reduces dimensionality while maintaining model accuracy, with XGBoost showing less than 1 ‰ R² degradation. Furthermore, the proposed multi-objective Non-dominated Sorting Genetic Algorithm-II (NSGA-II) outperforms the traditional Response Surface Methodology (RSM), achieving 59.63 kWh·t⁻¹ energy savings (equivalent to a 33.63 kg CO₂·t⁻¹ reduction) at a target CF roughness of 0.60 μm. The Pareto front further confirms the excellent dual-optimization capability of NSGA-II, which achieved a 10.15 % energy reduction while maintaining product quality. This study provides new insights for intelligent copper foil production and enables greener manufacturing paradigms.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"525 ","pages":"Article 146617"},"PeriodicalIF":10.0,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145043020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study aimed to address this gap by conducting a wood preference survey and analyzing the concentration characteristics of pollutants, including BVOC, particulate matter (PM), carbon dioxide (CO₂), formaldehyde (HCHO), and anthropogenic volatile organic compounds (AVOC), through scale model experiments and elementary school wood remodeling. Additionally, the carbon storage potential of the wood employed was quantitatively assessed. The results revealed that α-pinene, which accounted for over 90 % of monoterpene concentrations, was present at high levels. Notably, BVOC concentrations from knotted wood were observed to be up to 2.7 times higher. Furthermore, the concentration of particulate matter decreased in the remodeled environments, indicating that the use of wood could enhance indoor air quality. Finally, with respect to carbon storage, sites primarily utilizing hardwood exhibited a 144 % greater carbon storage capacity compared to others, underscoring the considerable influence of wood type and density on carbon storage potential.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"525 ","pages":"Article 146597"},"PeriodicalIF":10.0,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Using mechanical disintegration, we investigate the impact of scrap size and defibration time on fibre and suspension properties. Our results show that a broad processing window exists, with effective fibre separation achievable through relatively coarse cutting and moderate defibration times. The resulting suspensions were blended with industrial recycled paper stock and used to produce handsheets, which were evaluated for key packaging-relevant mechanical properties: tensile strength, bending stiffness, and short-span compression strength (SCT). A blend with 30 % textile-derived fibres yielded papers with equal or improved mechanical performance compared to reference sheets made from industrial paper stock alone. These findings support the feasibility of incorporating post-consumer cotton textiles into packaging paper production. Due to the large demand of fibres for packaging paper the proposed processing pathway has the potential for diverting significant volumes of textile waste from disposal. Rather than competing with fibre-to-fibre recycling, this approach targets lower-grade waste and proposes a complementary route toward more comprehensive circularity in the textile and packaging sectors.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"525 ","pages":"Article 146524"},"PeriodicalIF":10.0,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

First, without a shift in consumer behaviour aligned with circular economy principles, effective implementation is not possible. Second, insights into consumer engagement across diverse socioeconomic groups are crucial for guiding businesses and policymakers in designing effective strategies and interventions to foster circular behaviours.

The existing technologies for recovering phosphate from wastewater as struvite granules bear the high costs of chemicals and slow growth of struvite crystals.

This study advances a novel chemical-free approach for recovering struvite from sludge digestate as granular natural fertilizers that have great potential to be allowed for use in certified organic production. First, simple air stripping and gravity settling were applied to raise pH and precipitate Mg²⁺-competing cations in filtrate of sludge digestate. Mineral products (calcined magnesite and Epsomite) were then added to the pretreated filtrate in a 21.5-L air-lift crystallizer for only 45 min of struvite crystallization and settling. 90.2–95.6 % of phosphate was removed from the pretreated filtrate. With pretreatment, the purity of struvite crystals reached 93.5 %. The crystals were pressed into granules with organic binders (xanthan gum and guar gum) allowed for organic production. The granules made at struvite crystals: guar gum: water weight ratio of 10 : 0.8: 5.4 had physical properties close to those of commercial triple superphosphate.

Oxy–fuel combustion has emerged as a promising technology for the synergistic control of pollutants. However, the underlying mechanisms remain insufficiently understood. This study integrates experimental and theoretical methodologies to elucidate the dual–inhibition pathways of representative aromatic hydrocarbons and NO_x occurring in O₂–CO₂ atmospheres. Based on the results of Fourier transform infrared and thermogravimetric analysis, it is observed that the optimized 35 %O₂–65 %CO₂ atmospheres most effectively suppress the formation of naphthalene, styrene, and thermal NO_x by approximately 73 %, 65 %, and 86 %, respectively, compared with the traditional O₂–N₂ atmospheres. Furthermore, the degradation pathways of aromatic hydrocarbons and NO_x under O₂–N₂ and O₂–CO₂ atmospheres are thoroughly investigated. It is found that under O₂–N₂ atmospheres, H•–mediated fuel nitrogen chemistry pathways promote the formation of NO_x precursors. Conversely, under the O₂–CO₂ atmospheres, both the polymerization of aromatic hydrocarbons and the formation of NO_x are effectively suppressed through a triple mechanism involving H• extraction, delayed oxidation and HO₂• generation. Subsequently, quantitative chemical calculations further confirm this finding. The introduction of CO₂ can significantly reduce the activation energy of the H• generation reaction (68.2 kJ/mol for O₂–N₂ atmospheres vs. 37.5 kJ/mol for O₂–CO₂ atmospheres) and alter the reaction pathway, thereby enhancing the inhibition of aromatic hydrocarbons and NO_x. This technique has crucial implications for air quality management and contributes to enabling clean lignite use in addition to mitigating greenhouse gas effects.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"525 ","pages":"Article 146618"},"PeriodicalIF":10.0,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
