In this study, we employed a novel deep eutectic solvent (DES) composed of 1-tetradecyl-3-carboxymethylimidazolium bromide (C₁₄CIMBr) and lactic acid (LA) for the pretreatment of <em>Moringa oleifera</em> Lam. husk <em>(M. oleifera</em> husk), aiming to enhance lignocellulose fractionation. The optimal conditions identified were 165°C, 43.9 minutes, and a molar ratio of C₁₄CIMBr to LA at 1:4.8, resulting in the removal of 93.8% of lignin and 96.8% of hemicellulose. Following enzymatic hydrolysis of the pretreated <em>M. oleifera</em> husk, yields of glucose and xylose reached 94.3% and 86.1%, respectively, representing significant increases by factors of 7.0-fold and 10.3-fold compared to untreated <em>M. oleifera</em> husk. Molecular simulations indicated that the novel DES effectively disrupts the original internal hydrogen bonding network while reconstructing new DES-lignocellulosic hydrogen bonds, it also demonstrates excellent solubilization capabilities for lignin cleavage products. Finally, the yield of regenerated lignin reached 81.3%, exhibiting notable bactericidal activity under blue light irradiation.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"168 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665234","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}

An empirical study on scrapping intentions","authors":", Sarada Prasad Sarmah, Nikesh Nayak","doi":"10.1016/j.jclepro.2024.144254","DOIUrl":"https://doi.org/10.1016/j.jclepro.2024.144254","url":null,"abstract":"This study examines consumer intentions toward scrapping End-of-Life vehicles (ELVs) to understand how vehicle scrappage policies might alleviate environmental deterioration caused by emissions from outdated vehicles. The research objective is to assess the factors influencing consumer decisions regarding vehicle scrappage, using a model grounded in the Theory of Planned Behavior (TPB). Data was collected from 403 valid responses and analyzed using exploratory factor analysis, confirmatory factor analysis, and structural equation modeling.The findings reveal that the original TPB model accounts for 58.3% of the variance in consumer intentions to scrap vehicles. However, incorporating sociodemographic variables into the model increases the explained variance to 80.6%, with perceived behavioral control as the most influential factor, followed by consumer attitudes. We found that subjective norms do not influence consumers' intentions to participate in scrappage programs. Younger consumers were more likely to support vehicle scrappage, while environmental concerns alone did not foster a positive attitude toward scrappage.In conclusion, while consumer intentions to scrap vehicles are primarily influenced by control and attitude, targeted interventions are needed to enhance policy adoption. Key managerial implications include: promoting acceptance through tailored advertisements, offering differentiated subsidies, engaging younger audiences through awareness campaigns, and redefining promotional strategies to encourage ELV scrappage effectively.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"10 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665231","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}

The method encompasses identifying ship motion states, extracting features, compressing time series data based on these features, and performing cluster analysis. It has been applied to process over 12.6 million data points, demonstrating its applicability to a large dataset. The results indicate that by using actual measurement data and the proposed methodology, three typical operational conditions for ships were successfully established. There are significant differences in the feature parameters among these conditions, highlighting the distinct characteristics of each operational state. The validity of the constructed typical operational conditions was confirmed through a validation process, which involved analysing the differences in feature parameters and comparing the probability distributions of speed and acceleration to the overall dataset. Additionally, energy consumption and emission levels calculated using the typical conditions were validated through comparison with real-world data from upstream and downstream voyages.

The effect of WAS pre-treatment with different surfactants on membrane performance were investigated in terms of flux variation, membrane rejection and fouling mechanisms. A generalization form of blocking law was developed to determine membrane fouling mechanism. According to the results, cationic surfactant below critical micelle concentration (CMC) values improved membrane performance, while anionic and non-ionic surfactant showed a negative impact at all dosages. It was observed that WAS pretreatment with 300 mg/L Cetyltrimethylammonium bromide (CTAB) could increase the water flux from 195 to 611 L/m²/h (LMH) and decrease the rejection rate from 93% to 85%, respectively. Although CTAB addition increased the total extracellular polymeric substances (EPSs) amount from 56.16 to 119.6 mg/L which was due to the surfactant solubilization property, the total resistance decreased from 0.33×10¹⁰ to 0.11×10¹⁰ m^-1. This was attributed to the flock formation induced by CTAB through charge neutralization and bridging mechanism. Modeling simulation of the results indicated that CTAB addition transformed fouling mechanism from cake to intermediate-blocking model. The environmental risk assessment revealed that only 0.3 mg/L surfactant penetrated in permeate which was low ecological risk (risk quotients (RQ) &lt; 0.5) to the aquatic environment. Our finding suggested CTAB treatment at low dosage (0.1 g/L) as a promising and efficient approach for fouling mitigation and improving membrane process for wastewater treatment.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"50 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665235","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 conducts a comprehensive analysis of water pollution complaint in Japan from 1989 to 2021, utilizing integrated datasets that include river networks, water quality monitoring stations, regional industrial demographics, and socioeconomic indicators. Our findings reveal a significant decline in complaints—over 45% from the peak in 2006—following the implementation of various environmental policies aimed at reducing industrial discharge and restoring natural ecosystem function. The shift in complaint targets from industries to individuals suggests that these policies have been effective in mitigating industrial pollution, while also highlighting the need to address individual behaviors that impact water quality. Despite long-term improvement in water quality indicators such as Suspended Solids (SS) and Dissolved Oxygen (DO), no significant correlation was observed between these indicators and the temporal or spatial patterns of water pollution complaints. Instead, a strong positive correlation was observed between complaints and reported water quality incidents, reflecting heightened public sensitivity to acute pollution events. Spatial analysis further identified a significant association between complaints and the manufacturing workforce, indicating that industrial activity continues to shape public perception of water pollution risks. Our findings underscore the complex interaction between public perception, environmental policies, and industrial activities, and suggest that effective water management requires a multifaceted approach. Policymakers should continue to enforce stringent industrial regulations, while also enhancing public education and communication strategies to improve awareness of individual responsibilities in water protection. This research provides a theoretical basis for developing more responsive and effective environmental policies and public education strategies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"18 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665236","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 process destroys the primary seepage state of the deep aquifer, resulting in waste and pollution of deep water resources and posing a significant threat to coal mining. Therefore, through field measurement and numerical simulation, this paper comprehensively analyzes the development law of coal seam mining overlying rock fracture, and determines the influence range of coal seam roof water inrush. Then, a set pair variable weight - forward associated cloud prediction model is constructed to predict the dominant water inrush window and seepage channel of coal seam roof, and the key protection area of coal mining roof water inrush is delineated. The results show that with the continuous advance of the coal face, the stress shifts to both sides of the face, forming a stress concentration area, and the vertical fissure develops intensively, which becomes the main channel of water inrush. After the development is stable, it is comprehensively determined that the fissure production ratio of the coal seam is 11.7, and the fracture zone extends to the aquifer area are the water inrush source. Then, through the prediction model, the edge of the danger area near the high-risk area is defined as the advantage window of coal seam roof water inrush, and the result is consistent with the actual water inrush event. Therefore, the target of water inrush in roof is determined, and the effective measures of water reduction mining are put forward.

This work investigates the removal of As(V) using Fe-modified biochar derived from de-oiled Mentha waste (MMBC). The study aimed to synthesize MMBC and evaluate its adsorption capacity; secondly, to investigate adsorption kinetics; and lastly, to elucidate the governing mechanisms behind the process. Proximate analysis revealed MMBC's stability (low moisture: 6.48%, high fixed carbon: 54.7%) and high adsorption potential (low volatile matter: 9.77%). Characterization techniques (SEM-EDX, XRD, FTIR, TGA) confirmed a desirable porous structure, favourable chemical composition, and surface functionality critical for As(V) adsorption. Importantly, MMBC exhibited a significantly larger surface area providing more active sites (378.08 m² g⁻¹) as compared to the unmodified biochar. Concerning operational conditions, the optimal As(V) removal was achieved at pH 7.5 with a 25 mg/50 mL MMBC dosage in a 24 h contact time. Further, kinetic modelling indicated a pseudo-second-order mechanism, suggesting chemisorption as the dominant process. However, isotherm studies revealed favourable multilayer adsorption, with the Freundlich model best describing the data. The combined effects of MMBC's porosity, functional groups, and Fe modification facilitated both physical and chemical adsorption mechanisms. These findings highlight MMBC's potential as a promising biochar-based adsorbent for efficient As(V) removal from contaminated water for sustainable remediation.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"32 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645887","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}
