In addition to its dual functionality of electrosorption and catalytic activity, this environmentally friendly synthesis avoids the use of organic solvents and metals, reducing its environmental footprint and costs. Initial tests on sulfamethizole (SMZ) adsorption and electrosorption were conducted with both hydrochars, with HC-C demonstrating superior performance. The optimization of HC-C content in the composite revealed that 10 wt%(GCN@HC-C10) provided the best results. Using this composite around 95% SMZ removal under electrosorption at 1.2 V was achieved in only 120 min. The compound was then immobilized on a carbon felt electrode (GCN@HC-C10/CF), which facilitated its practical application and reuse in real water systems. The durability of GCN@HC-C10/CF was validated by five cycles, and its photocatalytic regeneration under visible LED light resulted in minimal reduction of adsorption capacity (<8%). The hybrid electrosorption-regeneration process successfully mineralized SMZ during photoregeneration, highlighting the potential of GCN@HC-C10/CF for efficient and sustainable pollutant removal. To our knowledge, there are no previous studies reporting green catalytic materials with dual functionality such as the one presented here. Finally, tests on real water samples (tap and river) underline the applicability of the material in various water purification contexts, positioning it as a promising candidate for water purification applications.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"7 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820697","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}

Investments in supertankers involve substantial capital, and the payback period is lengthy. The complexity and uncertainty of the shipping market have posed higher requirements on ship investment behavior. The prices of newbuilding supertankers are significantly influenced by the fluctuation of the shipping market, with numerous potential factors and complex interrelationships. To quantitatively investigate the volatility mechanisms of the supertanker market, this study focuses on the prices of newbuilding Very Large Crude Carriers (VLCC). Several representative economic indicators are introduced, and the variable selection principles of ridge regression analysis are utilized to screen factors with low relevance and multicollinearity. Through the econometric model, the relationships between factors and the prices of newbuilding VLCCs are revealed, thereby determining the key factors. Results indicate that the importance of interrelated factors is ranked as follows: the ratio of new ship orders and fleet size, steel plate prices, second-hand ship prices, international exchange rates, and one-year time charter rates. This empirical study also provides certain theoretical and practical guidance for shipowners in making reasonable investment decisions regarding the newbuilding supertanker market.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"5 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816286","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}

During the process of aligning stakeholders' decisions to maximize benefits, challenges such as information asymmetry and the lack of a suitable business model can impact the stability of the promotion mechanism for the combined system. Hence, this study, which considers the role of village collectives, develops various business models and establishes an evolutionary game model to examine the equilibrium states of the government, integrated energy service providers, village collectives, and rural households in different scenarios using a typical rural area in Xi’an as a case study. It concludes that the involvement of various stakeholders is crucial for the widespread adoption of the combined system. The product-oriented business model, characterized by joint investments from households and integrated energy service providers, and the rental-oriented business model, with investment solely from energy service providers, are suitable business models for promoting the combined system. Increasing the revenues of village collectives can enhance the willingness of integrated energy service providers and rural households to participate. For systems exceeding 9 kW, a product-oriented business model is appropriate if the investment ratio of rural households surpasses 30% or if rooftop rent is below 90 yuan/kW/year. For systems under 9 kW, the thresholds are a 20% investment ratio or rent below 150 yuan/kW/year. Otherwise, a rent-oriented business model will be more suitable for various stakeholders.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"29 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820699","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}

Based on this finding, the main objective of this research is to identify key elements for sustainability that should be incorporated into the instruments for assessing the quality of Higher Education Institutions (HEIs). Two complementary methods were used to achieve this objective: literature review and document analysis. The main result of the research is the presentation of a list of 18 key elements that should be integrated into the evaluation instruments of HEIs, enabling an evaluation based on indicators capable of measuring the incorporation of sustainability in the teaching, research, outreach, and operational activities of these institutions. As a secondary result, it was found that the approach to sustainability in the higher education evaluation instruments used in Brazil is limited, requiring modifications that allow the evaluation process to promote, in the long term, a more proactive role of HEIs in the training and awareness of students regarding sustainability.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"29 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820705","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 paper focuses on the potential of the EU transitional agriculture, circular policies, and new regional perspectives in reducing food loss among food supply chain stakeholders. Combining sustainable supply chain analysis and local case studies on policy implementation, this paper addresses beef farmers in North Karelia, Finland, where beef production is based on a multistage farming system of growing bulls progressing food loss control along food supply chains. Findings indicate that chances to achieve a zero level of food loss in North Karelia are challenging, if not unlikely. Despite the challenges, North Karelian beef farmers are not without hope. The North Karelian beef farming system holds significant potential for improvement, where inspiring challenges to achieve zero food loss among North Karelian farmers is not impossible. This article evaluates farmers’ ability and willingness to implement the Farm to Fork strategy, affecting the overall level of food loss. It assesses the means and the proportion of losses that should be reduced.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"5 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820747","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 Intergovernmental Panel on Climate Change (IPCC) provides guidelines for GHG quantification at both national and global levels. However, the IPCC Tier 1 (T1) and Tier 2 (T2) estimates, mostly used in national inventories, rely on generic emission factors (EFs) and empirical equations that are not suitable for case-specific assessments on individual farms. Thus, a more advanced Tier 3 (T3) methodology is needed to reflect the impact of key factors on emissions and reveal the effect of emission mitigation measures. Here we compare the IPCC T1 and T2 estimates to results from a cascade of process-based (PB) models referred to as T3 approach, for farm-level emissions. The results showed that the estimates from PB models differ significantly from those of the IPCC T1 and T2 estimates and allow more capability to predict variation. Moreover, PB models account for temporal changes and the underlying mechanisms responsible for GHG and N emissions. These models can be adopted for case-specific GHG assessment and project future mitigation strategies under different climate scenarios, regional contexts and on-farm management. Additional to the known applicability of PB models to estimate enteric methane and soil emissions, the present study demonstrates for the first time in Germany and Europe the effectiveness of Manure-DNDC model in simulating ammonia (NH₃) and methane (CH₄) barn emissions, highlighting the potential for using PB models in case-specific GHG and N assessments for the whole manure management chain. Overall, this study presents options for a methodology in case-specific GHG assessment that can capture the effect of climate change and mitigation measures.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"47 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820698","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, previous studies have predominantly relied on static approaches, which fail to account for the dynamic changes in the life cycle of C&DW management, thereby limiting the scalability and transferability of information across diverse spatial and temporal contexts. To address this gap, a dynamic life cycle assessment (LCA) model was developed with assistance of system dynamics (SD) method to evaluate environmental performance under various C&DW reduction (C&DWR) policies. This model simulates the real-time impact scores of Italy’s C&DW management (C&DWM) system for the period 2010 to 2050. Initially, a base model was developed to evaluate the environmental impact of C&DWM. The base model was subsequently expanded to evaluate various C&DWM scenarios, including resource use, CO₂ emissions, and overall environmental performance. Scenario analyses suggested that the adoption of waste reduction policies (e.g., simultaneously increasing landfill tax, decreasing design changes, applying low-waste technologies, and improving regulation execution) could effectively mitigate resource use and environmental burden. The results demonstrated that these policies would significantly influence the life cycle performance of C&DW. The environmental impact of the integrated policy exceeded that of all single policies. The integrated scenario, which would result in the greatest reduction in carbon emissions, exhibited considerable benefits. Furthermore, it is recommended to promote the development of C&DWM measures and renewable energy with high utilization rates to mitigate the impact of waste accumulation and ensure sustainable development.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"245 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820701","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}
