P/S-BC showed a high adsorption performance for Cd(II) and strong tolerance for the change of environmental pH, and the maximum uptake amount reached 204.26 mg/g. Furthermore, the bioavailability of Cd was significantly reduced by 37.27% with addition of 1.0% P/S-BC into soil for 20 days. Noticeably, when crushed fresh SV and 1.0% P/S-BC were applied to soil, the bioavailability of Cd in soil descended by 58.01%, meanwhile, the contents of soil organic matter (SOM) and available phosphorus (AP) in soil increased sharply, thereby improving the soil fertility. This double improvement was owing to that the application of P/S-BC could release more P through the action of organic acids produced by the decomposition of SV, which further bound with Cd to form stable compounds. The synergistic passivation mechanisms of SV + P/S-BC on Cd were surface chelation, precipitation, pore filling, and electrostatic interaction.

We found 12.5% increment in citrus yield (per unit area), and 20.6% and 65.0% decrement in fertilizer and pesticide inputs, while 78.8% increment in compost inputs during this period due to various management practice applications, including fertilizer reduction, organic fertilizer instead of inorganic fertilizer and green pest control. The CF and ecological costs were reduced by 53.3% and 25.0% due to these practices' application. By further adopting RAF50, a scenario combining the recommended fertilization amount of citrus with organic-N replaces 50% of inorganic-N, we predict the CF and ecological costs of China's citrus production will decrease by 67.9% and 37.5% in 2060.

However, loading MOF powders into a polymer matrix to form composites often relies on organic solvents and rigorous manufacturing processes. Here, we propose a biomimetic mineralized molecular engineering strategy, enabling robust, large-scale fabrication of MOF-fabric composites without organic solvents. This strategy allows MOF nodes to be embedded between highly elastic state polymer molecular chains, achieving strong physical anchoring. The preparation process realizes a significant reduction in carbon emissions (30%-50%) and high production efficiency (10 kg/h) while maintaining excellent fixation fastness, including resistance to washing (over 25 times), rubbing (over 100 times), and light (over 12 h). Furthermore, the applications of MOF-fabric composites in personal protective equipment are demonstrated, including organic gas adsorption, UV protection, and antibacterial. Our work provides a sustainable pathway towards the practical application of MOF-fabric composites.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"35 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485950","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}

In the era of growing interest in air quality and widespread access to spatial data, there are increasingly more solutions in the field of maps and portals illustrating the concentration of air pollutants. They vary in detail, content, and analytical capabilities. Currently, there is no standardized cadastre of emissions and air quality that universally provides residents with information about air quality in selected places around the world. Therefore, the objective of this paper is to propose a model solution for the construction of the Emission and Air Quality Cadastre (EMAC). Business analysis methods were used in the research. To assess the macro-environment, i.e., external factors influencing the construction and development of EMAC, PESTEL analysis (identifies factors in six key areas: Political, Economic, Socio-cultural, Technological, Ecological, and Legal) and scenario analysis of environmental conditions were used. To assess existing map portals, the functionalities of which should appear in EMAC, the competitive profile assessment method was used. The implementation of the EMAC can contribute to increasing air quality awareness among residents of their area, encourage the implementation of actions to promote a healthy lifestyle, and help authorities take effective measures to protect the urban environment.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"48 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486109","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}

Green consumption significantly influences green agricultural production. However, current government subsidy policies lack specific measures for green agricultural consumption. To advance environmentally-friendly agriculture, this study develops a tripartite asymmetric dynamic evolutionary game model. It focuses on the internal interest relationship among farmers, government, and consumers. Through numerical simulations, it analyzes the impact of key parameters like government subsidy intensity and distribution ratio on evolution. The findings suggest that green production and consumption subsidies are more effective when farmers and consumers have high motivation to engage in eco-friendly practices. Conversely, increasing subsidies may have negative effects when their motivations are low. Moreover, consumer-oriented subsidies, compared to subsidies for farmers alone, can significantly increase demand for green consumption and benefit farmers more, thus promoting sustainable agriculture effectively. The findings propose corresponding measures and suggestions for governments, consumers, and farmers to further promote environmentally-friendly agriculture.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"174 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486077","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}

Although effective, conventional de-icing methods incur high expenses and cause significant environmental contamination to the surrounding environment. To address these longstanding issues, a low-cost novel coal-derived carbon enabled smart pavement (CDC-SP) de-icing system was developed, aiming to alleviate traffic delays, severe corrosion, compromised safety, and environmental pollution. However, the economic performance of CDC-SP has not been quantified to guide decision-making. To this end, this paper presents a Life-Cycle Cost-Benefit Analysis (LCCBA) to assess the economic feasibility of the CDC-SP de-icing system for road bridges in five representative urban and rural areas across cool humid and cold humid climate zones. Given the variations and uncertainties of several factors that determine the costs and benefits, a sensitivity analysis was conducted to determine the system's economic reliability. Additionally, Monte Carlo Simulation (MCS) was performed to quantify the impacts of important factors and identify the most beneficial scenarios. The CDC-SP de-icing systems have demonstrated substantial economic benefits and short payback periods, showing great applicability for rural and urban road bridges with different service levels across multiple climate zones as compared to conventional de-icing methods.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"27 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486078","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, life cycle assessment (LCA) studies of bio-based plastics use varied methodologies and have shown large discrepancies, making it difficult to compare outcomes. This article presents an LCA of 31 scenarios for bio-based high-density polyethylene (HDPE) and bio-based polyethylene terephthalate (PET) based on life cycle inventories from literature. The scenarios included various biomass types, production locations and chemical conversion processes. Even the methodologically consistent LCAs yielded large discrepancies in outcomes. Conducting methodologically consistent replications allows us to study the factors that affect the environmental impact of bio-based plastics. Six key factors that contribute to variations were identified. The limited public information and limited scoping of the studied LCAs resulted in life cycle inventories that did not cover all relevant impact categories. A harmonised scope and life cycle impact assessment with more transparent reporting is therefore needed to improve the reliability of bio-based plastic LCAs in the future. A section of the studied LCAs did provide sufficient information to study the effects of bio-based plastic production processes, which yielded the other four factors: biomass type, processing, electricity, and heat. Understanding the factors from practice provides additional information about how bio-based plastics should be developed and how their LCAs should be interpreted.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"9 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486070","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}

Likewise, in these global discussions, structural justice considerations are practically absent. Therefore, there is a need to study private-sector attempts to integrate justice principles in CE transitions and the perspectives of Global South private CE actors, especially for nations such as Colombia, where CE firms are on the rise. Hence, this study explores the perspectives and contributions of four CE case study firms in Colombia by analyzing their perspectives on the CE, Just Transitions, and their contributions to a Just CE transition. For this purpose, a qualitative study with interviews and field observations of those firms was performed. Findings revealed deviations from mainstream CE definitions and scope, which, unlike the former, stress the need for a socially Just CE that mends local social fractures, challenging mainstream CE transition assumptions and meanings. Additionally, results suggested the need to merge local perspectives with CE strategies to improve efficacy and cultural appropriateness. Likewise, social inclusion was identified as essential for a Just transition. This study contributes to the Just Transition literature by giving a voice to Global South CE actors to promote CE policy discussions as spaces of intercultural co-construction and reduced exclusion.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"22 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486072","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 proposed a sustainable conversion pathway from low-grade solid waste→composite cementitious materials (CCMs)→high-performance foamed concrete (FC) through synergistic activation and cascading utilization. The findings indicated that the hydration processes of solid waste-based iron-rich calcium sulfoaluminate (IR-CSA) clinker, phosphogypsum (PG), and low-reactivity slag exhibited notable synergistic effects and asynchronous characteristics. The hydration of clinker and excess PG mainly occurred in the early stages, while slag was slowly activated under low alkalinity and persulfate conditions, continuously forming C-(A)-S-H gel and new AFt in the later stages. Slag substitution enhanced the long-term performance stability of CCM while causing changes in porosity, hydration phase proportions, and microstructural morphology. CCM containing only 15% clinker achieved a 180-day compressive strength of 74.3 MPa. During FC preparation, the setting characteristics of the composite pastes effectively accommodated the expansion behavior induced by H<sub>2</sub>O<sub>2</sub> foaming. All FC samples exhibited a specific compressive strength exceeding 4.77 N·m/kg, with the lowest thermal conductivity recorded at 0.136 W/m·K. The sustainability assessment demonstrated that FC was safe and environmentally friendly. Furthermore, the life-cycle carbon footprint per unit of specific strength for FC was reduced by 15.41%-61.29% compared to autoclaved aerated concrete. These results highlight the potential of this technology in advancing sustainable construction practices and promoting the valorization of industrial waste.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"129 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486074","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}
