It is essential to systematically monitor, manage, and evaluate circularity within the construction industry based on the needs and interests of stakeholders, as this can provide evidence for circular practices. However, the integration of CE increases complexities in the stakeholder network of the construction industry. Many stakeholders lack clarity about their roles, requirements, and aspirations in circular projects, leading to ineffective, hesitant, and ambiguous utilization of various circular measurement methods. To address those problems, this paper adopts a systematic literature review approach to conduct a comprehensive and critical review of measuring circularity from a stakeholder perspective. The paper categorizes stakeholders into 7 key groups and identifies their needs and dilemmas at specific stages of the circular project life cycle. Additionally, this study reviews the current development of circularity measurements at different stages of the circular project life cycle and discusses how well they align with stakeholders' needs and dilemmas. Finally, this study finds that there have been various attempts, but several essential prerequisites for comprehensive measurement are missing or incomplete. Several recommendations for measuring circularity that align more closely with stakeholder needs and address their current dilemmas are proposed. These findings are intended to enhance the evaluation, regulation, and oversight of CE in the construction industry, as well as to promote CE implementation.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"28 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991975","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}

While considerable research has examined the relationship between PM_2.5 concentrations and their driving factors, the nonlinear contributions of these factors, especially across different urban contexts, remain insufficiently explored. This study seeks to bridge this gap by applying interpretable machine learning (XGBoost) to investigate the nonlinear impacts of meteorological, socio-economic, environmental, and architectural variables on PM₁₀ and PM_2.5 levels. Specifically, we aim to understand how these factors' contributions differ across three major urban agglomerations (UAs) in China. Our findings reveal notable spatial heterogeneity, with meteorological variables, such as temperature, AOD, and evapotranspiration playing a predominant role in the BTH region, while architectural factors have a more significant impact in the PRD, contributing more than 60%. In the YRD, increasing standard deviation of building height (SDBH) to 20-40m and average mean building height (MBH) to 15-20m are associated with lower PM₁₀ concentrations. Notably, the impact of socio-economic activities on air pollution was also observed. For example, as NPP_VIIRS increased from 15 to 120, PM_2.5 concentrations in the PRD region decreased from 14 μg/m³ to 11.5 μg/m³, a novel finding not previously highlighted in related studies. Furthermore, the relationship between GDP and PM_2.5 concentrations follows a nonlinear pattern, initially rising and then declining, a pattern consistently observed across all UAs. Overall, this study underscores the spatial heterogeneity in the relationship between air pollutants and their driving factors, offering insights for region-specific pollution control strategies and broader global environmental management frameworks.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"45 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020149","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 study finds that SCF contributes to reducing carbon emissions in manufacturing companies. After conducting a series of robustness tests and controlling for potential endogeneity issues, this conclusion remains valid. Regarding the transmission mechanism, SCF's contribution to carbon emission reduction in manufacturing firms occurs through the pathways of corporate financial availability and green technology innovation. Further research shows that the promotion effect of SCF on carbon emission reduction of manufacturing enterprises is more obvious in areas with strong environmental regulations and high level of digital economy development, as well as manufacturing enterprises with high supply chain concentration and strong management ability.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"10 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991919","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, previous studies have not adequately addressed the characteristics of these zones from a comprehensive macroscopic perspective. To fill this gap, this study examines the Minjiang River Basin (MRB), which exemplifies a typical plateau–plain transition zone, dividing it into three areas: upstream, midstream, and downstream. Carbon density values were estimated based on land use and soil attribute data from 2000 to 2020, and the spatiotemporal distribution and changes in carbon storage were analyzed using the Integrated Valuation of Ecosystem Services and Trade-offs model along with Standard Deviation Ellipse Analysis. Sixteen natural economic indicators from 52 districts and counties were selected to construct a geographically and temporally weighted regression model, exploring the spatiotemporal heterogeneity of influencing factors across the basin. The results revealed the following: (1) From 2000 to 2020, total carbon storage in the MRB decreased by 5.563×10⁶ t, with the midstream region accounting for 83.93% of this decline. (2) The dominant factors influencing carbon storage were nighttime light (NL) and relative humidity, with average influence intensities of -0.181 and 0.111, respectively. (3) Influencing factors exhibited significant spatiotemporal heterogeneity; the upstream area was most adversely affected by NL, with a maximum regression coefficient of -3.29. In contrast, the midstream and downstream areas experienced relatively weak influences, primarily from the positive effects of annual production value in the primary industry and soil pH, which had maximum regression coefficients of 0.437 and 0.747, respectively. These findings provide robust data for assessing regional carbon sequestration capacity in the MRB and offer a theoretical basis for conducting ecological protection and managing human activities in areas with complex terrain.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"10 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991917","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}

From this perspective, the search for environmentally friendly processes that supply energy and materials from waste is growing. Hydrothermal carbonization (HTC) is a promising thermochemical process that converts waste into a solid product named hydrochar. Hydrochar, given its physicochemical characteristics, has the potential for several applications (e.g., energy production, soil amendment, and adsorption of water pollutants), which has boosted the research interest in HTC. Several studies have focused on optimizing HTC conditions and evaluating the environmental and economic aspects of this process through life cycle assessment (LCA) and techno-economic analysis (TEA), respectively. However, despite the increasing number of review articles about feedstocks, optimal conditions, and reaction mechanisms of HTC, a critical review focused on HTC sustainability is lacking in the literature. Therefore, this review provides a critical outlook on LCA and TEA studies concerning HTC to verify its environmental and economic sustainability from a broad perspective. Overall, some studies have demonstrated the environmental and economic feasibility of HTC, as evidenced by the current technology readiness level (TRL) of this thermochemical process, which has reached industrial implementation in the last decade. Moreover, this waste valorization approach can evolve into a multi-product biorefinery, in addition to becoming a potential contributor to the achievement of some Sustainable Development Goals (SDGs).","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"42 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992042","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 move from a dataset composed of five variables for CE, two for ET, and three for SJ, representing yearly data for the quinquennium 2016-2020 and European countries. We build a multilayer network based on the ten variables having countries as nodes. Each layer/variable has weighted links based on countries’ similarity. Inter-layer links are created through a community detection exercise over the individual layers. This approach allows us to evaluate analogies, leading to the assessment of intra- and inter-layer policy integration. We find a relatively low level of integration at the European level and a high sensitivity to the number of detected communities, thus revealing the role of countries’ heterogeneity in driving integration.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"50 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020147","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}

Health-beneficial properties of microalgae, coupled with advantageous characteristics such as high biomass productivity, adaptability, robustness, and carbon dioxide mitigation, position them as a viable solution for global sustainable food production. This study explored clean and environmentally friendly processes to enhance the recovery of lipid bioactive fractions. Microwave (MW), enzymatic (ENZ), and ultrasound (US) pretreatments were applied to improve environmentally friendly extraction of lipid-based components using supercritical CO₂. The effects of these pretreatments on extraction yield, chemical profiles, and cytotoxic properties of <em>Chlorella vulgaris</em> (Cv) and smooth <em>C. vulgaris</em> (sCv) extracts were investigated. Additionally, a Life Cycle Assessment (LCA) was conducted to evaluate environmental impacts. MW pretreatment achieved the highest yield increases, from 2.58 times (Cv) to 3.15 times (sCv). UHPLC-ESI-HRMS analysis revealed shifts in the distribution of pigments and derivatives caused by pretreatments, with ENZ extracts showing the most pronounced changes: pigments increased from 9.24% (control Cv) to 40.92% (Cv) and from 12.52% (control sCv) to 71.12% (sCv). Cv extracts exhibited greater activity against MDA-MB-453 cells, while sCv extracts from US pretreatment demonstrated the strongest effect on HeLa cells. The LCA indicated reduced environmental impacts of the pretreatment-enhanced processes up to 65% compared to the control. A scenario analysis was presented to show further possible impact reduction by recirculating the CO₂ solvent and substituting the energy source.

Compared to Zr-NC MFC, the maximum power density of Fe-Zr-NC MFC increased from 3.62 to 5.25 W/m², and the coulombic efficiency increased from 18.23% to 26.37%. In addition, Fe-Zr-NC improved the total capacitive behavior contribution of bioanode, increasing the limiting storage capacity of biocapacitor from 4207.46 to 10582.28 C/m². Furthermore, the exchange current density of the Fe-Zr-NC bioanode increased from 0.65 to 1.43 mA/cm², while the charge transfer resistance decreased from 3.72 Ω to 1.08 Ω. Electrochemical measurements and density functional theory (DFT) suggested that the charge redistribution of Fe atoms at the bimetallic catalytic sites increased the interfacial potential difference of the terminal conductive protein and the strong adsorption of flavin species, thus regulating the dominant EET pathway and charge transfer kinetics.

Improvement of the efficiency of this method is essential for new and matured SAGD projects to minimize the project cost and the amount of carbon emitted for steam generation. Adding hydrocarbon (HC) solvents to steam can effectively improve the recovery efficiency of SAGD by improving the recovery per amount of the steam used. The optimization of this process requires further clarifications and understandings on the fluid-steam-rock interactions, especially at the pore scale. For this purpose, a visual two-dimensional physical porous media model was constructed and HC additive-assisted SAGD (HC-SAGD) process was studied. Heptane was selected to represent the HC phase as it its boiling point is close to water. The effects of physicochemical properties of the oil-steam-water-heptane and fluid-rock interactions on the growth of the steam chamber and oil drainage were visually analyzed. The oil recovery efficiency, energy efficiency and carbon emission intensity of HC-SAGD and SAGD were compared for different scenarios to suggest optimal operational conditions. It was shown that the introduction of HC can reduce carbon emission intensity to that of the half of conventional SAGD while improving heavy oil recovery. It was also observed that the technical and economic benefits of solvent addition to steam in the SAGD process could be much higher than previously anticipated.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"81 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020145","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}
