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}

This study aims to develop a predictive model for estimating biogas production from the anaerobic digestion of various organic wastes. The model was constructed based on the theoretical biogas generation potential of each type of organic waste and their biodegradation rates, depending on their mixing ratios. To ensure the reliability of the model, the coefficients of determination (R-squared, R²) for indicating explanatory power and significant F values for statistical significance were analysed, and the accuracy of the models was assessed by A measure that evaluates how well a predictive model predicted real-world data, the root mean square error (RMSE) by applying the models to data from 20 Co-AD plants in operation. The results showed that the estimation model was statistically significant.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"65 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486075","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}

By examining Tesla's case, this study dissects the mechanism of human-machine collaboration-driven sustainable business models. The findings reveal that: 1) Human-machine collaboration encompasses cognitive, structural, and relational dimensions. 2) It bolsters enterprises' dynamic capabilities, including customer value analysis capability, resource intelligence integration capability, and value extension reinvention capability. 3) The framework \"Human-machine collaboration-dynamic capabilities-sustainable business models\" is established. This mechanism model elucidates how human-machine collaboration impacts diverse value propositions, adaptive value creation, and inclusive value capture by influencing capabilities in customer value analysis, resource intelligence integration, and value extension and reinvention.

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, its implementation remains limited due to socio-economic and technical barriers. To better understand this phenomenon, the study is framed by the diffusion of innovations model, which provides an analytical framework to assess how, why and at what rate new agricultural practices diffuse in a given population. This study examines the barriers to adoption in Spain, Italy, Egypt and Tunisia. A qualitative analysis of interviews with 20 farmers from these countries, along with a literature review, reveals that while the environmental benefits—such as improved soil health and biodiversity—are widely recognized, economic disincentives, uncertainty over carbon credits and resistance to change hinder adoption. The complexity of carbon farming techniques and limited access to specialized equipment slow down diffusion further, especially in rural areas where information dissemination is ineffective. In addition, the lack of immediate economic benefits discourages investment, while the misalignment with traditional farming practices fosters skepticism. To improve uptake, the study stresses the need for clearer financial mechanisms, targeted educational programs and policy adjustments that add value to traditional farming practices.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"8 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495899","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 investigates the environmental impacts of two laboratory-scale methods for graphene production, focusing on their potential applications in electronic devices. The Hummers' method effectively produces high-performance reduced graphene oxide; however, it has faced criticism due to toxic emissions. In contrast, the production of graphene from biomass waste through pyrolysis offers a more environmentally friendly alternative for sustainable manufacturing. A cradle-to-gate life cycle assessment (LCA) is conducted, focusing on three biomass waste materials: banana peel waste, wheat straw waste, and Populus wood waste (PWW), which serve as precursors for graphene production via potassium hydroxide (KOH) activation. The analysis evaluates global warming potential (GWP) and cumulative energy demand using two functional units: 1 kg of produced graphene and a conductivity normalized unit for specific applications. The results indicate that graphene production from PWW is considerably more environmentally sustainable, reducing the GWP from 4,841 kg CO₂ equivalent per kg in the Hummers' method to 115.86 kg CO₂ equivalent per kg for PWW-derived graphene. The results obtained from the comparison of hydrazine-reduced graphene oxide (h-rGO) and graphene derived from PWW, based on FU2, illustrate that the total energy consumption for h-rGO per 1 mg. S^-1.m^-1 is 15 times higher than that for graphene derived from PWW. Electricity consumption is identified as the highest contributor to environmental impacts in graphene production, particularly given the current Iranian electricity mix, which heavily relies on fossil fuels. Furthermore, the usage of KOH was a notable contributor to the environmental impact, with 83% of the GWP impact for PWW-derived graphene attributed to electricity consumption and 13% to KOH consumption. A sensitivity analysis based on three scenarios is conducted, which includes a transition to renewable energy, a 20% reduction in electricity consumption, and a 20% reduction in KOH usage. The results showed that transitioning to renewable energy sources, such as wind power, could significantly reduce environmental impacts. This study illustrates the potential environmental advantages of utilizing biomass waste as a precursor for graphene production.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"25 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495940","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}
