Therefore, it is particularly important to detect HCZs in tap water, yet this process is time-consuming and labor-intensive. To address this challenge, developing predictive models for HCZs based on water quality parameters presents an attractive alternative. Unfortunately, no prediction studies for HCZs have been reported to date. This study investigated the feasibility of using linear models, log-linear models, backpropagation neural networks (BPNN), general regression neural networks (GRNN), and radial basis function neural networks (RBFNN) to predict the occurrence of HCZs, including 3-chlorocarbazole (3-CCZ), 3-bromocarbazole (3-BCZ) and total halogenated carbazoles (ΣHCZs) in tap water. The input parameters for BPNN, GRNN, and RBFNN were selected based on grey relational analysis (GRA) results, while the linear and log-linear models were developed using stepwise regression. The results showed that linear and log-linear models were not suitable (N₂₅=0.30-0.64, <em>r</em>_<em>p</em>=0.40-0.71), and BPNN demonstrated limited prediction performance (N₂₅=0.52-0.78, <em>r</em>_<em>p</em>=0.77-0.83). GRNN excelled only in predicting ΣHCZs (N₂₅=0.98, <em>r</em>_<em>p</em>=0.96). Particularly, RBFNN exhibited good performance in predicting 3-CCZ, 3-BCZ, and ΣHCZs (N₂₅=0.70-0.89, <em>r</em>_<em>p</em>=0.89-0.94), providing valuable insights and possibilities for real-time monitoring of HCZs in tap water.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"29 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823315","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}

Therefore, many studies have been conducted to recycle and reuse scrap tires in other areas. One such area is the asphalt pavement, where the crumb rubber (CR) from scrap tires are recycled for asphalt modification. This study focuses on improving the coating properties, and moisture resistance of the rubberized asphalt materials, with the proposed chemical soaking pre-treatment methods. The Fourier transform infrared (FTIR) spectroscopy results revealed significant changes in the CR surface chemistry after pre-treatments, involving the reduction and oxidation of chemical bonds. There was a decrease in the C-H functional group when treated by heating in distilled water and soaking in a potassium permanganate solution. In addition, the intensity of the peaks related to the ether functional group increased when soaking in a potassium permanganate solution. It was further found that the pre-treatment methods enhanced the coating properties of rubberized asphalt mixtures. Meanwhile, the pre-treatment efficacy was notably affected by the binder type. This study demonstrated substantial improvements in the moisture resistance of rubberized asphalt materials following the proposed chemical CR pre-treatment.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"10 5 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823248","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}

Electric arc furnace (EAF) steelmaking realizes the recycling of waste scrap resources and improves the sustainable development. However, there is still no public reports about the CFs-MFs-EFs of EAF steelmaking, which leads to the lack of data support and directionality for saving and reduction optimization. To fill this gap, the China-style EAF steelmaking with hot metal (HM) and scrap is concentrated. The carbon-material-energy flows nexus (CME-FN) is determined by the successively established mathematical models of MFs, EFs and CFs based on the steelmaking mechanism and chemical reactions. The EAF actual production data and literature data are used to verify these models. The effects of electricity, carbon powder and natural gas on CME-FN are further discussed. The results reveal that in EAF steelmaking with full HM (EAF-FHM) and full scrap (EAF-FS), the metal charge and material consumption to produce 1000 kg of molten steel are 1103.4/1298.4, and 1037.9/1077.4 kg, respectively. Considering the energy demand of 549.9 and 437.2 kWh, the input energy of 678.0 and 65.3 kWh leads to the surplus energy of 128.0 and -371.9 kWh. The direct and embodied equivalent carbon dioxide is 166.7/2884.7, 13.5/46.1 kg CO₂ eq. EAF-FS enjoys better reduction benefits on material consumption and carbon emission, but shows less energy supply performance than EAF-FHM. Electricity changes the HM ratio, strengthens the HM surplus energy utilization, and has positive effects on CME-FN. Carbon powder and natural gas slightly aggravate the material and energy consumption and direct carbon emission, but cut down the embodied carbon emission. Although the China-style mode is focused, the method and analysis can be extended to other EAF patterns of related countries and technologies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"19 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823247","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}

Upcycling can help slow and close resource cycles through product life-extension. Cities offer opportunities for upcycling initiatives and seek to tackle challenges in urban solid waste management by encouraging entrepreneurs to create value from local waste streams in urban resource centres and circular crafts centres. However, little is known about what drives urban upcycling and which barriers and drivers occur. This study explores urban upcycling in the context of the Dutch furniture industry, since The Netherlands positions itself as a ‘circular economy hotspot’ and furniture offers promising opportunities and best practices for upcycling. The analysis of 29 semi-structured interviews with experts engaged in urban upcycling reveals personal motives, drivers and barriers. Personal motives include (1) a personal purpose to ‘do good’, (2) an urge to challenge the status quo and (3) learning and inspiring by doing. Key drivers entail opportunities to (1) engage in collaborative experimentation, (2) participate in cross-sectoral local networks, (3) develop resource-based adaptive competences, (4) respond to increasing demand for upcycled products and (5) make social business activities financially viable. Key barriers perceived by upcycling experts include (1) limitations in resource availability, (2) increasing capacity requirements, (3) negative public quality perception, (4) limited marketing competences and (5) an unequal playing field. This study contributes with a comprehensive definition of urban upcycling and a structured overview of key factors that drive and constrain urban upcycling.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"102 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823053","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}

A notable innovation of this study is the development of a modified structural path betweenness approach that improves measurement accuracy by addressing the issue of repetitive calculations found in previous methodologies. The findings indicate that this refined method significantly mitigates the overestimation issue inherent in assessing the importance of intermediary sectors. Specifically, the Manufacture of Metal emerges as considerably more critical when functioning as an intermediary sector than as a participant in supply or demand sectors. Additionally, the study identifies crucial intermediary sectors where enhancing product utilization efficiency could yield substantial energy savings. Finally, alterations in energy consumption elasticity have appreciably narrowed the decline in China’s energy consumption growth rate. Policymakers need to consolidate existing environmental achievements and incorporate energy consumption from both demand and intermediary sectors into the regulatory framework.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"29 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820639","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}

To explore this issue, a three-year field experiment was conducted using two widely-used BFs (black and transparent BFs respectively) and traditional transparent PEFs as mulching materials to examine their aging characteristics and mulching effects in an irrigation maize field of northwest China (no-mulching as CK). The data revealed a noticeable decrease in surface integrity after aging for both BFs compared with PEFs, yet the surface cracks of BFs showed dispersed and randomly distributed characteristics. Particularly, BFs was not fully degraded within each growing season as desired, across 3 growing seasons. The aging properties of black and transparent BFs and their effects on soil functions were essentially indistinguishable. The aging of BFs significantly augmented the abundance of fragment- and fiber-shaped microplastics (MPs) in soils, relative to PEFs (<em>p</em>&lt;0.05). Intriguingly, BFs mulching achieved comparable soil warming effects as PEFs did, under sunny and rainy days in each growing season. However, soil water storage at plough and deep soil layer for both BFs was significantly lower than that of PEFs (<em>p</em>&lt;0.05). BFs mulching significantly improved the proportion of soil macroaggregates relative to PEFs (<em>p</em>&lt;0.05), and evidently decreased soil bulk density (<em>p</em>&lt;0.05). Moreover, it significantly improved soil labile organic carbon (LOC) content, while lowering soil total nitrogen, nitrate-nitrogen, and ammonium-nitrogen content relative to that of PEFs (<em>p</em>&lt;0.05). Critically, relative to PEFs, BFs mulching harvested similar crop biomass and economic benefits, and better soil functions. The findings provided new insights into the reasonable usage and management of BFs for better sustainability in agricultural practice.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"86 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820807","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 previous studies have emphasized the role of farmer cooperatives, concrete empirical evidences have been lacking. To fill this research gap based on the survey data from 1820 rural households and the registration data of 1106 corresponding cooperatives we examine the influence of farmer cooperatives on local collective environmental action such as manure recycling, waste sorting and wastewater treatment in the context of China’s Rural Human Settlements Improvements Initiative. Our results show that a mere 1% expansion in the size of local farmer cooperatives will increase the probability of household participation in manure recycling, waste sorting, and wastewater treatment by 4.4%, 5.6%, and 12.6%, respectively. The establishment of farmer cooperatives not only enhance institutional trust but also eases local financial constraints, thereby facilitating collective environmental action. Moreover, our heterogeneity analysis shows that the effectiveness of farmer cooperatives in promoting local collective action will be compromised by the emergence of <em>elite capture</em> (cooperatives with great ownership concentration) and <em>shell cooperatives</em> (cooperatives without actual agribusiness). These findings underscore the importance for policymakers to foster the development of cooperatives to improve rural waste and resource management.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"1 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820695","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 evaluates the potential for reducing GHG emissions from a typical large-scale dairy farm in the cold climate zone of northern China by integrating traditional and innovative biotechnologies. We conducted a life cycle assessment comparing a business-as-usual (BAU) scenario with a low-carbon dairy combined biotechnologies (LCBT) scenario. The BAU scenario reflects current practices, while the LCBT scenario incorporates integrated soil–crop system management (ISSM), methane inhibitors in cattle feed, and the use of microalgae and insects for manure treatment. The BAU scenario's total GHG emissions were 208.9 Gg CO₂eq, with enteric fermentation accounting for 55%. The LCBT scenario demonstrated a 50% reduction in GHG emissions, achieving a net emission of 105.1 Gg CO₂eq. Around half of the reduction is contributed by advanced biotechnology. Energy consumption increased under the LCBT scenario due to the high energy demands of insect and microalgae treatment processes, highlighting the need for a transition to clean energy, which may further reduce the emissions to 28% of that in BAU. The study underscores the potential of a comprehensive approach that combines sustainable agricultural practices with biotechnological advancements to reduce the carbon footprint of dairy farming. Policy implications include the need for regulatory support and incentives to facilitate the adoption of these technologies, particularly in cold climate regions where energy consumption for maintaining biological processes is a critical factor.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"29 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820694","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}
