Herein, the character, source, ecological risk of microplastics in two typical wetlands for 40 samples of QTP were investigated. The results demonstrated that the average abundances of microplastics in surface water of Nianchu river wetland and Maidika wetland were 1615±1505.8 items/m³ and 325±426.9 items/m³, respectively, while the sediment of them were 680.7±550.1 items/kg, 322.8±351.6 items/kg, respectively. Microplastics in surface water and sediments were predominantly fragments (Nianchu river wetland), film and sphere (Maidika wetland), transparency, and 100-500 μm, respectively. Polypropylene was the main types in QTP wetlands based on the intelligently identified by a machine learning algorithm (accuracy of 0.977). Residents, resident's life, tourist flow, agricultural and fishery activities are the main sources of microplastics in the wetlands. In addition, the abundances of microplastics have positively correlation with total nitrogen in water samples, annual precipitation, and nighttime light index. Compared with the incomplete parameters of other algorithms, Potential Ecological Risk Index combined microplastics abundance and type to give a more reasonable assessment of the microplastics risk level of QTP wetlands. That is, 88.9% of surface water and all sediment microplastics pollution are at low risk. However, attention should be paid to the sources of microplastics brought by tourism and residential life. The study is beneficial to supplement the data of microplastics pollution in the wetland areas of Qinghai-Tibet Plateau.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"22 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820702","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 a patent-based innovation dataset of China's A-share publicly traded companies from 2009 to 2020, the study reveals that corporate innovation is associated with the cost of equity. The results show corporate innovation and the cost of equity have an inverted U-shaped relationship. In the initial stage of innovation, corporate innovation leads to an increase in the cost of equity, exacerbating the problems it brought to the company; but in the middle and late stage of innovation, as the level of innovation increases, the cost of equity experiences a sharp decrease, suggesting that continuing participating in innovative activities can mitigate the problems and even reverse problems into benefits. This study also explores the role of government subsidies as mediator on the association between corporate innovation and the cost of equity. The findings show that subsidies mediate the relationship between corporate innovation and the cost of equity. Innovation can attract more government subsidies and meanwhile, there is an inverted U-shaped relationship between subsidies and the cost of equity. The results provide empirical evidence to encourage managers to invest in innovative activities and also suggestions to policy makers to inject more funds to initial-stage innovative companies to foster innovation development.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"21 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820700","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}

Here, we explored the dynamics and driving mechanisms of nitrogen and phosphorus across three major freshwater lakes with different RLC (DRLC) in the lower reaches of the Yangtze River through the Modified Mann-Kendall test, Entropy-weighted water quality index, and multivariate statistical analysis methods. Our results showed that NO₃^--N and NO₂^--N in the high RLC lake (Poyang Lake, PYL) exhibited a significantly increasing trend along with water quality deterioration (Z = 2.4312*; P = 0.0075 < 0.05), whereas TN, NO₃^--N, NH₃-N, and NO₂^--N in the low RLC lakes (Chaohu Lake, CHL; Taihu Lake, THL) exhibited a significantly decreasing trend along with water quality improvement. The pollution sources of the lakes were all dominated by external loads, and the continued water quality deterioration in PYL might be attributed to hydrologic conditions change and pollution loads increase. Differently from low RLC lakes, there was no significant spatial heterogeneity in nitrogen and phosphorus of PYL due to strong hydrodynamic mixing. Nitrogen and phosphorus were major contributors to water quality variation in high and low RLC lakes, respectively, controlled by hydrologic conditions and the biogeochemical behavior of nitrogen and phosphorus. An average of 58.2% of TN/TP in three lakes were in the range optimal for phytoplankton growth (10<TN/TP<30), nevertheless there were different seasonal patterns among DRLC lakes. The regulation of climate conditions and land use on the lake water quality also varied with DRLC lakes. This study would provide essential scientific evidence for water quality management in DRLC lakes contributing to the formulation of effective and targeted water pollution control strategies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"233 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816283","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 the data of listed companies, our result shows that corporate ESG performance negatively affects labor share, which means that continuous improvement in ESG performance has not been accompanied by an increase in labor share. To further analyze the reasons behind this finding, we have first examined the direct effects of the labor share variations, both in terms of wage rate and labor productivity, and then the three indirect effects, i.e. production scale, financing constraint, and technological innovation. Moreover, we discuss the heterogeneous effects between the ESG performance and labor share. It is noteworthy that we also verify the moderating role of environmental governance pressure. We find that the negative impacts of ESG performance are greater when firms face higher external environmental governance pressure. The findings of this paper help to clarify how synergies between ESG performance, labor share and environmental governance pressure can be developed under the SDGs in China.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"1 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809511","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 conducted a TEA and LCA based on the molten salt heating tire pyrolysis process coupled with a carbon black modification process, relying on data from a process-level demonstration project. TEA results show that the unit disposal cost per ton of tire is 2,090.6 RMB/ton. The Financial Internal Rate of Return (FIRR) is 19.62%, and the Payback Time (PBT) is 5.87 years. The LCA results show that the molten salt heating tire pyrolysis process has a positive impact on global warming, emitting 224 kg CO₂ equivalent for every ton of waste tires disposed of. When considering product substitution, the greenhouse gas emissions for this process are -1292.2 kg CO₂ equivalent, demonstrating high environmental benefits.

Its strong toxicity and teratogenicity bring environmental and health risks. Recently, numerous research papers focused on the removal (degradation, recovery, etc.) of NMP from NMP wastewater. However, no publicly available review was found. This review listed the industrial applications of NMP and the corresponding wastewater generation. Also, it comprehensively summarized and compared the main strategies used in NMP wastewater treatment, including physical-chemical separation and resource recovery, chemical degradation, and biological degradation. For high-strength NMP wastewater (≥ 10%), resource recovery strategy (physical-chemical separation methods, i.e. distillation, extraction, and pervaporation, etc.) was the preferential choice. For wastewater with relatively low concentrations of NMP, chemical/biological degradation methods were commonly used. With the advantages of low cost, less secondary-pollution, and high mineralization efficiency, biological degradation methods were further specifically discussed including (1) biological treatment process technologies, (2) isolation/enrichment of NMP-degradation strains/consortia and its bioaugmentation applications, and (3) microbial degradation pathway of NMP. Typically, the aerobic/anoxic/anaerobic degradation of NMP was systemically investigated, and NMP was frequently reported as a denitrification carbon source. Finally, research gaps need to be filled in the future to promote the development of NMP-biodegradation technologies, including aerobic granular sludge (AGS), heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria, NMP degrading fungi, synthetic biology technology and microbiome engineering based on the identification of more genes and key intermediates. This review provided guidance in NMP wastewater treatment and boosted the application of novel technologies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"229 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809757","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 China, a large amount of pollutant emissions is attributed to the use of coal for heating and power generation, which makes efficient energy utilization a critical task for air pollution prevention and control. This study systematically investigates the impacts of the Measures for the Administration of Heat-Power Cogeneration (HPC) policy on air pollution and its mechanism by applying the difference in differences (DID) model based on a panel data sample covering 296 cities in China from 2013 to 2020. The SO₂ and NO₂ concentrations based on satellite remote sensing data are both incorporated into our unified analytical framework. The empirical results reveal that compared with the nonpilot cities, the HPC policy can significantly alleviate SO₂ and NO₂ pollution by approximately 17.4% and 3.7%, respectively, which can also be confirmed by multiple robustness tests. Then, we also found that there are three main mechanism paths to the implementation of pollution mitigation by the HPC policy, including green technology innovation, energy structure optimization, and energy efficiency improvement. Furthermore, significant heterogeneity of the effectiveness of the HPC policy on SO₂ and NO₂ pollution control was captured, and the synergistic effect of is more obvious in cities with large populations, \"2+26\" key cities, urban agglomerations, and low-carbon pilot cities. Moreover, we found that the roles of the HPC policy in NO₂ abatement in low-carbon pilot cities and nonpilot cities did not reveal a significant difference. The findings of this paper can serve as a useful policy references and inspiration for the systematic planning of HPC projects and provide a reference for other areas with severe air pollution.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"20 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809758","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 capacity hinges on factors such as microbial community composition, environmental conditions, pollutant characteristics, and the presence of metals/metalloids, surfactants, or co-metabolites. Our meta-analyses, covering 3,095 data pairs across 158 microbial species and 148 pollutants, offer insights into the factors regulating microbial degradation of organic pollutants in sterilized mediums. Degradation rates were dependent on the compounds: hormones degrade fastest, largely by Basidiomycota fungi. Microbial monocultures have superior overall degradation capacity (+35%·day^-1) compared to mixed co-cultures (+8%·day^-1), particularly because monocultures have a 3.6 times faster initial 5-day degradation rate. Fungal monocultures demonstrate greater resilience to additional compounds (i.e., metals/metalloids, co-metabolites, surfactants) than bacterial monocultures, attributed to their broader enzymatic and metabolic capabilities. Degradation rates under aerobic conditions are sevenfold faster than in anoxic environments, as oxygen is the strongest electron acceptor, boosting energy production for microorganisms. Metals/metalloids generally reduce microbial degradation efficiency (-21%), primarily by reducing oxidoreductase activities (-54%). Surfactants accelerate degradation (+18%) by solubilization of hydrophobic compounds and increasing oxidoreductase (+27%) and hydrolase (+44%) activities. Biosurfactants perform exceptionally (+45%) by increasing pollutant solubility and altering microbial cell membrane permeability. These findings generalize effective strategies to accelerate microbial degradation of organic pollutants and to optimize remediation conditions in contaminated environments.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"82 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816284","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 biofunctionalized nylon membranes (ELPs-SC-NMs) exhibited excellent stability and only 8.5% loss after being incubated at 4 °C for 15 days.

The retention of the XTL was up to 95.2% after 6 days of incubation at 4 °C, and the activity of xylanase in XTL was still 79.8% of the initial value after 18 days of storage, which was increased by 278.2% compared with free xylanase. In addition, the covalent immobilized XTL showed excellent reusability, which remained 74.7% (xylanase) and 77.5% (lichenase) of the initial activity after 8 uses, respectively. Moreover, the immobilized multi-enzymes were applied for clean production of reducing sugars from biomass, the substrate conversion rate and total reducing sugar content were close to those of free enzymes. They also exhibited more excellent catalytic properties than free ones in the clarification of fruit juices. The universality of our strategy was also demonstrated on poly(vinylidene fluoride) membranes.

The discussion results showed that the adoption of IFGs led to a shift in the R&D direction and that to resolve the problem of rare metals in view of a sustainable society, it is essential, in the short term, to establish resource recycling systems, and in the medium to long term, to substitute rare metals with ubiquitous elements, or to develop new mining sites. The questionnaire responses showed that participants who adopted an IFG viewpoint tended to place greater importance on “productivity” and less importance on a “simple process” as indicators of technological development and implementation, showing changes in the perceived importance of associated indicators.
