Notwithstanding comprehensive study, considerable knowledge gaps persist in comprehending the complex interrelations among water quality measures and in determining effective evaluation methodologies. This study utilizes explainable artificial intelligence (XAI) to thoroughly examine the connections among eight essential water quality measures and to determine the most dependable predictions for efficient monitoring and management. A thorough comparison examination of four machine learning models was performed, employing a unique scoring mechanism created exclusively for this research. The Random Forest model exhibited superior performance, as indicated by its attainment of the lowest Root Mean Square Error (RMSE) values, a generally recognized measure of model correctness. Dissolved Oxygen was identified as the primary predictor, exhibiting a minimum RMSE of 0.127589 across several river datasets. This discovery highlights the significance of Dissolved Oxygen as a crucial metric for evaluating water quality. The study underscores the significant impact of river-specific attributes, highlighting the necessity for customized assessment methodologies for various aquatic ecosystems. This study enhances the scientific comprehension of water quality evaluation by incorporating explainable AI to elucidate the intricate interrelationships among metrics. The results confirm the efficacy of AI-driven methods in environmental monitoring and offer practical insights to inform the creation of precision water management strategies. This work addresses essential information deficiencies, aiding in developing more effective and sustainable strategies for reducing water quality deterioration and protecting aquatic ecosystems. The results indicate that the suggested methodology provides a dependable and comprehensible technique for predicting water quality, which can greatly assist water experts and policymakers.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"13 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030841","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 paper provides a comprehensive overview of the utilisation of IOT in cementitious composites, focusing on the various methods used to activate IOT and examining the durability along with mechanical properties of IOT-based cement mixtures. The findings indicate that while IOT has potential as a cement alternative, its inert crystalline structure requires activation. On the other hand, substituting IOT as fine aggregates enhances mechanical and durability properties. However, to avoid performance degradation, its replacement should be limited to 25%. Additionally, it summarises the environmental, economic, and social viability of using IOT in construction and presents current challenges and future research recommendations. Overall, IOT can be effectively utilised in cementitious composites, particularly as a replacement for natural aggregates, without significant losses.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"206 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031405","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}

We identify the product processing and usage stages in macroalgae’s life cycle contribute most carbon emissions, while the net primary production of macroalgae during growth only partially neutralizes its overall CO₂ emissions. A sensitivity test for such life cycle model indicates employing clean energy and improving technical efficiency can potentially achieve net-zero for some macroalgae products e.g., biochar.

The hydroxyl group of lignin, the epoxy group of the crosslinking, and the amino group of the curing agent cross-linked and solidified to form a three-dimensional macromolecular structure, which greatly enhanced the adhesive's mechanical strength and chemical stability. The highest dry board bonding strength, wet board bonding strength, and weather resistance strength of lignin-based adhesives were 5.55 MPa, 2.05 MPa, and 1.7 MPa, respectively, which met the Chinese national standard GB/T 9846-2015 (≥0.7 MPa). Additionally, the VOC test showed that the total organic volatile content of the adhesive was 30.5 g/L, which met the Chinese standard GB 18583-2008 (≤ 350 g/L).

This study offers a dual benefit of waste management and resource conservation by repurposing PVC as aggregates in cementitious systems. The study aims to explore the impact of substituting natural aggregates with up to 100 vol.% of two types of PVC—soft PVC from electric wire coverings and hard PVC from water pipes—on the fresh properties, mechanical strength, physical performance and environmental impact of the limestone-calcined clay cement (LC3) system. Incorporating both hard and soft PVC reduced the flowability significantly. In addition, flexural and compressive strength of LC3 mortars declined by around 52% and 48% for H-PVC, and by around 64% and 87% for S-PVC mixes, respectively. However, completely substituting natural aggregates with PVC enhanced thermal insulation by up to 60% compared to control samples. The thermal conductivity of LC3 containing 100 S-PVC achieves the requirements of RILEM to be considered as an insulating lightweight cementitious material. PVC incorporation exhibited mixed effects on sound insulation. On the other hand, the total absorbed energy increased significantly by 290% and 305% for 100% hard (HPVC) and 100% soft (SPVC) samples, respectively, compared to the control sample. Conversely, the peak impact force slightly decreased for LC3 with HPVC, while LC3 with 100% SPVC showed a reduction of about 53%. The use of PVC aggregates remarkably diminished the carbon footprint of the selected mix designs, suggesting that recycling PVC into aggregate for cementitious materials offers a sustainable solution for both load-bearing (HPVC) and non-load-bearing (SPVC) applications.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"22 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030843","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 research work presents the development of sustainable and improved thermal and acoustic biocomposite solution based on coconut fibres and sodium alginate designed for building applications. Different mix designs have been examined to investigate the effects of water and binder content on the mechanical performance of the samples. The biocomposite developed exhibited a maximum flexural stress and compressive stress at 10% deformation of 1 and 1.13 N/mm² respectively, revealing a superior performance when compared to conventional mineral wool solutions used in construction. Based on the mechanical performance, a biocomposite formulation was selected for thermal and acoustic characterization. Additionally, samples with different surface geometries have been produced for improved acoustic performance. Thermal characterization revealed a thermal conductivity value of 0.091 W m⁻¹ K⁻¹, while a sound absorption averages (SAA) ranging between 0.46 – 0.62 was obtained, making the developed material a well-absorptive solution suitable for reverberation and echo attenuation applications, whilst offering good thermal insulation properties. The development of this innovative biocomposite highlights that a dual purpose bio-based insulation solution can be effectively produced with coconut fibre and sodium alginate, with competitive thermal and acoustic insulation properties, constituting a promising and sustainable alternative to conventional insulation solutions used in construction.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"123 3 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026764","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}

Based on the “Technology-Organization-Environment” (TOE) framework, the empirical results indicate that the dual pilot policy combination substantially fosters digital innovation, with R&D diffusion, human capital diffusion, and public environmental concern serving as pivotal transmission mechanisms. The empirical evidence also demonstrates that the positive impact of the policy combinations of dual pilot cities on digital innovation varies depending on geographical location, urban administrative level, and city size. Moreover, building upon the new economic geography theory, the empirical results indicate that the spatial spillage of the dual pilot policy has a positive impact on digital innovation, with a spillover boundary of 250 km. These insights underscore the importance of strategic policy combinations and can guide governments in designing effective digital innovation incentive policies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"59 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026765","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 necessitates the adoption of an all-encompassing holistic, multidimensional, and multi-stakeholder approach. In an era where economic growth has predominantly driven all industries, integrating environmental sustainability into business strategies and, subsequently, into daily operations is increasingly emerging. Different levels (macro, considering the national healthcare system; meso, focusing on a single hospital or healthcare facility; and micro, concerning the single process) might be considered to address the unmet need to transform the healthcare sector towards a net-zero emissions approach, especially for the environmental impacts and carbon footprint generated by this industry.A more comprehensive framework emerges as a priority for both scholars and practitioners, to manage and synthesize these aspects. To achieve this objective, a scoping literature review was conducted, including 72 articles, as the starting point for the development of a holistic framework, and then the Nominal Group Technique was applied to perform the validation phase, measuring the experts’ agreement on the framework proposed. The latter comprises three principal dimensions: <em>i)</em> infrastructure, <em>ii)</em> organisation, and <em>iii)</em> technology, emerging as the primary units of analysis for evaluating environmental sustainability within the healthcare sector. By assessing these three main outlined dimensions, decision-makers and healthcare professionals can gain a comprehensive understanding of sustainability performance. This will guide the evaluation process and provide a structured approach to assess current and future practices, set targets, implement actions, and monitor progress towards environmentally sustainable goals. This is also important in relation to international and national policies, such as the 2030 Agenda. The present research aims to investigate the available evidence on the topic and suggest a new framework. This proposed model aims to overcome the existing limitations, related to already proposed one-dimensional framework or models concerning only limited and not integrated aspects (building, supply chain or HR management). It also aims to provide guidance to healthcare professionals and policymakers in making informed decisions and prioritising interventions that comply with environmentally sustainable principles.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"33 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020105","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}

However, the specific mechanisms through which social comparison information impacts practical applications remain unclear. Grounded in the social comparison theory within behavioral economics, this paper investigates the application of social comparison information in water saving behavior interventions. To this end, we conducted a large-scale field experiment in China over a period of 10 months, using a difference-in-differences model to rigorously assess the effects of eight types of social comparison information on water-saving behaviors among urban residents. The aim is to explore how spatial distance, monetary framing, horizontal comparisons, and historical comparisons influence the effectiveness of social comparison information in promoting water conservation. The findings reveal that the water-saving efficiency of social comparison information exhibits an inverted U-shaped trend, initially increasing and then decreasing with decreasing spatial distance of the comparison group, with the \"apartment community comparison\" being the most effective in encouraging water-saving behavior. Moreover, while there is no significant difference in the impact of monetary versus non-monetary framing of social comparison information on water conservation, monetary framing appears to somewhat diminish prosocial motivation. Additionally, social comparison information outperforms historical comparisons, which showed no significant effect on water-saving behavior, even among low baseline users. This study provides vital policy implications for leveraging social comparison messages to enhance urban household water conservation efforts.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"74 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026768","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}

Based on insights from 21 in-depth stakeholder interviews with OT staff, procurers, suppliers, laundering services, and field experts, the study showcases the growing desire of clinicians to shift to a reusable medical textiles system. Yet, financial pressures, lack of integration with the infection control function in hospitals, legacy of customs and practices, supply chain complexities, and a lack of in-house sterilisation and laundry capabilities currently stand as main barriers in the way of adopting reusable medical textiles.
