It is crucial to explore the decarbonization pathways of the plastic packaging industry to help fulfill greenhouse gases emission (GHGs) reduction targets. We use material flow analysis and lifecycle assessment method to investigate nine scenarios based on eco-design, circular economy, and technological innovation. We analyze the consumption and GHGs of China’s plastic packaging industry from 2000 to 2020, exploring the potential for GHGs reduction under different scenarios. The results show that China’s plastic packaging consumption will continue to grow from 2020 to 2060, reaching 74.6 million tonnes (Mt). Plastic packaging consumption in the food sector is predicted to surpass that of the non-food sector in 2044. Meanwhile, polyethylene will become the predominant plastic used in the packaging industry. By 2060, the transportation sector will have the largest in-use stock of plastic packaging. The policy combination scenario can achieve GHGs peaking before 2030, while a GHGs gap of 32.9 Mt will persist until 2060. By further improving the recycling rate, reducing the consumption of degradable plastics, and increasing the application of carbon capture, utilization, and storage (CCUS) technology, the plastic packaging industry is expected to achieve the net-zero carbon emission target.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"7 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083271","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, it remains unclear how these stressors shape the profiles and transfer of fatty acids in basal resources, and subsequently affect the trophic linkages in stream food webs. We collected 158 food web samples including three basal resources (periphyton, fine benthic organic matter (FBOM) and seston), two primary consumers (macroinvertebrate and omnivorous fish), and one secondary consumer (carnivorous fish) together with water quality samples across an anthropogenic disturbance gradient in a small catchment (Laoguan River) of the Yangtze River, China. We investigated the influence of riparian land-use changes, canopy cover and water quality on the nutritional quality indicated by the proportions of eicosapentaenoic acid (EPA) in periphyton, seston and FBOM and their transfer in stream food webs. Our results showed that land use primarily affected the reduced the proportions of EPA in periphyton more than seston and FBOM. It was confirmed that loss of canopy coverage reduced the proportions of EPA of periphyton due to the significant correlations and difference between two groups: the least disturbed group (forest > 90%) and the highly disturbed group (high agriculture/urban). Compared to the least-disturbed sites, food webs appeared to be simpler with less trophic linkages at highly disturbed sites affected by agricultural and urban land uses. Finally, we validated that EPA was the important linkage between periphyton and primary consumers-macroinvertebrates, and further second consumers- omnivore fish, which may account for the decrease of network of trophic links at highly disturbed sites. This study provides insights into how anthropogenic stressors, particularly land-use changes and loss of riparian canopy cover, affect the nutritional quality of basal resources and simplify food web structures in stream ecosystems, highlighting the critical role of eicosapentaenoic acid (EPA) in linking trophic levels.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"141 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083230","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}

Findings indicate that the impacts of urban land use on pesticide ecological risks surpass the traditionally recognized agricultural effects, demonstrating significant spatial scale-dependent effects. Generalized additive model analysis reveals that 1−3<!-- --> <!-- -->km and 2−3<!-- --> <!-- -->km buffer zones represent the critical ranges where urban land use and cropland, respectively, have significant impacts on pesticide risks. Non-parametric change point analysis determined critical land use thresholds triggering significant ecological risk increases: 10−25% for cropland and 10−30% for urban areas.

This study addresses this limitation by incorporating two-dimensional (2D) zinc(II) tetrakis(4-carboxy-phenyl)porphyrin (Zn-TCPP) metal-organic framework (MOF) nanosheets as interlayers in TFC membranes (TFNi), using a polyethylene glycol (PEG) assisted exfoliation technique to mitigate issues of nanosheet restacking and aggregation. The uniformly distributed MOF interlayers significantly improved pure water permeance from 10.6 to 32.1 L m⁻² h⁻¹ bar⁻¹ while maintaining a high rejection of 97.0% towards Na₂SO₄. Moreover, the optimized membrane showed significant improvements in OMP removal, attributed to the increased negative charge and greater hydrophilicity of the polyamide rejection layer. These findings highlight the potential of 2D MOF nanosheets as interlayers in developing high-performance membranes for effective OMP removal and water reuse.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"34 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083147","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}

High concentration input directly increases the contents of SOC and DOM, stimulating the production of halomethanes. Second, changes in soil nutrients after nitrogen input indirectly inhibited the abundance of Actinobacteria, inhibiting the consumption of halomethanes.
