Herein, a biomass-derived carbon loading strategy was adopted to transform the reaction pathway from radical to non-radical. First, CuOx-C@CCDC (CCDC denotes the carboxylated cotton-derived carbon) was fabricated with Cu-MOFs/cotton as precursors. Serving as a PMS activator, CuOx-C@CCDC performs well for Fenton-like degradation of sulfoxazole (SIZ), attributing to the synergism between CuOx-C and CCDC, and its apparent rate constant (<em>K</em>_obs) for CuOx-C@CCDC was found to be 6.47 and 10.44 times higher than that of CuOx-C and CCDC, respectively. Mechanistic analysis by a series of characterization technologies including <em>in-situ</em> Raman spectroscopy, <em>in-situ</em> Fourier infrared spectroscopy, electron paramagnetic resonance spectroscopy, and electrochemical analysis unveiled that the radical pathway dominated by ^•OH made the main contribution in the CuOx-C/PMS system. In contrast, the electron-transfer-mediated nonradical pathway was responsible for SIZ degradation in the CuOx-C@CCDC/PMS system, wherein CuOx-C@CCDC functioned as the conductive mediator to transfer electron from SIZ to the surface-confined PMS*. Benefited from this, other electron-rich refractory organic pollutants including sulfamethoxazole, ciprofloxacin and tetracycline hydrochloride could also be efficiently eliminated. In addition, its superiorities including good recyclability, robustness, wide pH range, strong anti-interference against various inorganic anions and adaptability for actual wastewater display a promising prospect. Overall, this work provides a facile and feasible strategy to regulate the reaction pathways in PMS-based advanced oxidation processes.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"79 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867283","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}

For individuals, a substantial challenge lies in breaking up and transforming dominant, unsustainable practices and structures in place. Shifting consumption patterns and routines can contribute to changing such practices, but in democratic societies in particular, stronger levers lie in collective, political participation processes: Individuals can partake by electing representatives who can challenge the car-centric mobility system, or by engaging in citizen initiatives and protests to back up niche innovations and demand policy changes. However, citizen engagement for a sustainable mobility transition faces several structural challenges rooted in the characteristics of the car-centric mobility system.In this paper, we theorize how these characteristics of the car-centric regime influence psychological processes underlying motivation for collective action participation. Based on the Social Identity Model of Pro-Environmental Action (Fritsche et al., 2018), we highlight how motivational factors like a common social identity, collective efficacy beliefs and ingroup norms and goals develop in relation to the specificities of the context the collective action occurs in. We exemplify how the systemic level interacts with individual, within-actor processes and thereby provide a critical perspective on collective action research in transport. This paper explores and delineates intersections between transition studies and collective action research and sketches an interdisciplinary research agenda to advance our understanding of engagement of citizens in mobility activism.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"77 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867284","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 compared artificial neural network (ANN), support vector regression (SVR) and random forest (RF) for Pb²⁺ adsorption capacity by biochar from a fluidized bed system. Besides developing correlations for comparison, the RF model (R² = 0.984, RMSE=0.054) outperformed both ANN (R² = 0.908, RMSE=0.316) and SVR (R² =0.667) in predicting higher adsorption capacity. Based on the superior performance, the Shapley Additive Explanations (SHAP) were employed on RF. SHAP global explanations indicated that adsorption conditions contributed 69.03% and biochar characteristics contributed 30.21%to adsorption capacity, highlighting Dosage (D) and Carbon (C) as the crucial factors. Regarding biochar characteristics, element compositions contributed 76.59%. The single samples demonstrated that the final predictions align with the experimental results. The synergistic effect of dependence plot explains the Pb²⁺ adsorption under varying parameter conditions, such as D&lt;1g/L, C&lt;45%, Pb_in&gt;100mg/L, H&lt;2.5, t&gt;12h, T&gt;25°C, pH&gt;9, H/C&gt;0.4, the SHAP value is positive, contributing to an increase in adsorption capacity. Furthermore, a graphical user interface (GUI) leveraging SHAP model parameters predicts adsorbent performance, providing novel insights into optimizing biochars production.

One of the main challenges in DAC processes is the high energy and economic costs associated with airflow systems in large-scale air contactors. Recently, there has been a growing interest in using hydrate lime to capture low concentrations of CO₂ (∼450 ppm) from the atmosphere, particularly at higher air relative humidity. Cooling towers, commonly used in various industrial units to cool process water, provide an ideal environment for hydrated lime-based DAC systems as they expose large flows of ambient air to water. This study assessed the feasibility of integrating vertically oriented parallel flat plates of Ca(OH)₂ into the upper section of an industrial mechanical draft cooling tower to simultaneously perform the dual tasks of water cooling and CO₂ capture from the passing air. Results of an unsteady-state Shrinking Core Model (SCM) showed that 425 cooling towers of 20×20 m² cross-sectional area accommodating 5-meter long Ca(OH)₂ vertical plates of porosity 0.55, thickness 2 cm, and distance between adjacent plates of 2 cm can achieve an annual CO₂ capture rate of 1 million tons if the carbonated plates are replaced 4 times a year (3-month cycle duration). By utilizing a scaled-up centralized calcination unit for the regeneration of the recycled sorbent, the estimated final cost of the proposed DAC process is around $93.5 to $269 per ton of CO₂ captured which makes the proposed system a cost-competitive alternative among the state-of-the-art DAC technologies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"14 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867286","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 provides an advanced estimation of CO₂ uptake during the cement lifecycle in Japan by incorporating dynamic material stock-flow analysis into the model. Concrete stock-flow and CO₂ uptake from 1870 to 2070 are estimated by reflecting country-specific characteristics such as concrete mix design, surface-to-volume ratio of buildings, presence or absence of coating resins and/or covering materials, and exposure climate. Annual CO₂ uptake in the cement lifecycle was estimated to be 2.6 million tonnes/year in 2020, corresponding to 13.9% of CO₂ emissions from calcination during cement production. Annual CO₂ uptake by in-use concrete accounted for 86.8% of the total in 2020, whereas that by end-of-life concrete was relatively small throughout the estimation period. CO₂ uptake is expected to increase slightly in the late 2020s, then decrease to 2.3 to 2.4 million tonnes/year by 2070. Our results were lowered by comparing those of previous studies, suggesting that the most critical aspect was affected by the local climate. The high-precision analysis highlighted the importance of integrating local climate factors, surface-to-volume ratio of structures based on the domestic design guidelines and examples, and modeling of end-of-life concrete, providing fundamental knowledge for incorporating CO₂ uptake into the carbon-neutral strategy of Japanese cement industry.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"24 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867331","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}

Herein, Co-MOF-71 was prepared by hydrothermal method using terephthalic acid (TPA) obtained from the hydrolysis of waste PET plastics as an organic ligand, and the derived cobalt/carbon composite (PETC) was prepared by carbonizing Co-MOF-71 under N₂ atmosphere. Characterizations revealed that PETC800 carbonized at 800 °C possessed a loose and porous layered morphology with a surface area of 148 cm²/g, and had a porous structure rich in active sites that are effective in peroxymonosulfate (PMS) activation and tetracycline (TC) degradation. Degradation experiments revealed that the maximum degradation rate of TC by PETC800 could reach 90.94% within 20 min, with a maximum rate constant of 0.2700 min^-1 and activation energy of 19.50 kJ/mol, which was lower than that of previous reports. Additional studies confirmed high effectiveness also towards other pharmaceuticals degradation such as metronidazole, levofloxacin and doxorubicin. More importantly, PETC800 could degrade TC efficiently in a broad pH region (3.0-9.0). The degradation performance of TC could be 72.18% after four cycles, demonstrating good reusability. Both radical (•OH, SO₄^•−, and O₂^•−) and nonradical pathways (singlet oxygen (¹O₂) and electron transfer) contributed to the TC degradation process, with the non-radical pathway dominating. LC-MS and toxicity analyses have postulated the degradation of TC into intermediates with lower levels of toxicity. The preparation of MOFs-derived catalysts from waste plastics allows resourceful utilization of waste plastics as well as enhances the catalytic performance of MOFs-derived cobalt/carbon-based catalysis for efficient degradation of emerging organic contaminants.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"65 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857919","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}

Using these methods, we investigated the effects of <strong><em>-CH</em></strong>_{<strong><em>3</em></strong>}, <strong><em>-CH</em></strong>_{<strong><em>2</em></strong>}<strong><em>OH</em></strong>, hydroxyl, and cyano groups on mercury adsorption performance at various sites on carbon surfaces. The results indicate that cyano groups significantly enhance mercury adsorption, while hydroxyl groups exhibit specific effects at different sites. Additionally, we proposed interaction mechanisms for two types of dual functional groups—linear superposition and synergistic effects.

Despite this, CFs continue to have high embodied carbon resulting from energy intensive processes used during production. This investigation uses lifecycle assessment to assess the impact of future energy scenarios and alternative feedstock materials in CF production, to generate data critical for informing long term decarbonisation strategies.Achieving net zero electricity generation alone can lead to approximately 50% reduction in CF Global Warming Potential (GWP), emphasising the critical importance of decarbonising electricity. This study also emphasises the imperative for lower-carbon solutions in the thermal energy used across the CF production value chain. Adopting BioMethane as a thermal energy alternative has the potential to achieve a 20% reduction in current GWP, offering a significant short-term mitigation strategy. Among thermal energy solutions, eMethane demonstrates the greatest long-term potential for CF decarbonisation, with a projected 99% reduction in GWP by 2050 compared to natural gas. Producers may consider BioMethane as a temporary solution (2025–2040) before transitioning to eMethane as the long-term thermal energy source (2035–2040 onwards) as electricity impact decreases.
