This study presents a novel hybrid energy system integrating sorption-enhanced chemical looping reforming of methanol (SECL-OSRM), a high-temperature proton-exchange membrane fuel cell (HT-PEMFC), and a recuperative–regenerative organic Rankine cycle (RR-ORC). A comprehensive process model was developed, and a multi-objective optimization (MOO) was performed by coupling Non-dominated Sorting Genetic Algorithm II (NSGA-II) with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method to maximize system efficiency while minimizing exergy destruction and total system cost rate. The best compromise solution, achieving a system efficiency of 42.04%, exergy destruction of 148.1 kW, and a total system cost rate of 11.67 USD/h, was obtained with CuO/CH₃OH and MgO/CH₃OH molar flowrate ratio of 0.5, a current density of 0.806 A/cm², an oxygen flowrate ratio of 4, a fuel cell temperature of 200°C, and an intermediate pressure of 9 bar. This study highlights an ideal framework for efficiently optimizing a hybrid energy system. It offers comprehensive information about the interactions between system components and parameters to help establish a new understanding for developing the next generation of advanced energy systems.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"33 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695641","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 response to the Paris Agreement and national “dual carbon” goals, this study explores a sustainable, low-carbon vanadium extraction process by introducing a novel cerium oxide (CeO₂)-catalyzed sodium roasting method. To address the challenge of limited knowledge on phase transitions in vanadium slag roasting, this study employs transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) to confirm the presence of metastable phases in the slag and to analyze CeO₂'s catalytic effects on phase transformation. The results reveal that CeO₂ effectively promotes the transformation of metastable phases and the oxidation of low-valence vanadium, forming stable, soluble vanadates (Na₄(V₂O₇)). Data indicate that adding CeO₂ enables a 5 wt% reduction in Na₂CO₃ usage while maintaining a vanadium extraction rate of over 90 %. Mechanistic studies further demonstrate that CeO₂ produces oxygen vacancies during roasting, activating a Ce³⁺/Ce⁴⁺ redox cycle that enhances oxygen utilization and accelerates vanadium oxidation. Furthermore, the regenerated CeO₂ catalyst retains catalytic activity after multiple cycles, achieving a vanadium extraction rate of 95 % upon reuse. This CeO₂-catalyzed roasting method significantly reduces Na₂CO₃ requirements, minimizing CO₂ emissions and hazardous residue production, thereby presenting an efficient, low-impact approach to sustainable vanadium extraction and contributing valuable insights for advancing green metallurgical processes.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"501 ","pages":"Article 145380"},"PeriodicalIF":9.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695639","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 focuses on Jalisco, Mexico, a major dairy-producing region, to assess the environmental impact of whey disposal. Through a combination of physicochemical analysis, geographic information systems, and Life Cycle Assessment (LCA), we investigated the current whey management practices and their associated environmental burdens. Whey samples from 19 dairy processing units were analyzed, revealing high organic loads with biological oxygen demand ranging from 9.42 to 50.05 g/L, and total nitrogen and phosphorus levels of 1019.93 mg/L and 171.72 mg/L, respectively, exceeding local and international discharge limits. The region produces approximately 322,942 m³ of whey annually, with 67 % concentrated in 10 municipalities. LCA compared three whey management scenarios: direct disposal (DD), anaerobic digestion (AD), and whey powder (WP) production. DD contributed to freshwater and marine eutrophication (0.26 kg P eq and 0.23 kg N eq, respectively). AD emerged as the most sustainable option, reducing greenhouse gas emissions and generating biogas as a renewable energy source. WP production, while adding economic and nutritional value, had a global warming potential of 96.89 Kg CO₂ eq due to energy-intensive processing. Centralized treatment systems were identified as a viable solution for small producers, enabling shared infrastructure and cost reduction. These findings provide a scalable framework for sustainable whey management strategies, applicable to other dairy-producing regions.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"501 ","pages":"Article 145334"},"PeriodicalIF":9.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687322","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 achieve this, innovative methodologies (namely, quantile-on-quantile regression, wavelet quantile correlation, and quantile causality) are employed, utilizing data from 1990 to 2022. The findings highlight that (i) an increase in green technology innovation primarily promotes environmental sustainability by decreasing ecological footprint at higher levels of green technology innovation, which is advantageous for the United States; (ii) an increase in environmental policy stringency typically has a beneficial impact on environmental sustainability at lower and medium levels of environmental policy stringency; (iii) The level of industrialization augments the ecological footprint in most quantiles; (iv) research and development positively influences environmental sustainability.

However, to improve state-of-the-art recycling technologies for full metal recovery, further research regarding their thermodynamic and kinetic behavior has to be done. While most publications about LIB kinetics focus on Cobalt (Co) recovery from lithium cobalt oxide (LiCoO₂) chemistry, Li transition metal phosphates such as lithium iron phosphate (LiFePO₄) have been neglected. So far there is no fully working recycling solution for this cathode chemistry, considering demanding recovery targets. Carbothermic reduction could offer an elegant solution, using the carbon from the anode, to simultaneously recover Li and Phosphorous (P) via the off-gas and Iron (Fe), Copper (Cu) and other elements within an alloy. However, thermodynamic data, which are currently unavailable for LiFePO₄, are necessary for the process engineering of novel reactors, overcoming current limitations within pyrometallurgy. Therefore, this study investigates the kinetics and thermodynamic behavior of a synthesized LiFePO₄ black mass in a temperature range between 900 °C and 1200 °C. By using isothermal mass change analysis with corresponding phase and microstructure analysis, diffusion and nucleation related reactions could be identified. The phase analysis revealed the formation of highly stable phosphates such as lithium phosphate (Li₃PO₄) and aluminum phosphate (AlPO₄).

This paper reviews existing literature on MCI for buildings and proposes an enhanced framework, the “Enhanced Building Circularity Indicator (EBCI),” to address these limitations. The EBCI incorporates often overlooked factors such as lightweight design, recycling levels, modularity, and a whole lifecycle perspective. The framework is tested through Taiwan's Taisugar Circular Village (TCV), the country's first circular housing project, which integrates circular economy strategies, including circular materials, modular design, and Product-as-a-Service business models. Results show that the EBCI effectively assesses building circularity across material, product, system, and building levels, highlighting the importance of recycling levels, modularity, and lifespan extension in improving circularity. The study also discovers that different normalization factors (mass vs. economic value) significantly impact the results. Including renovation times (RTs) in the assessment leads to minimal differences in circularity scores, suggesting limited additional value for this factor. The EBCI provides a comprehensive and adaptable approach to assessing building circularity, offering valuable insights for policymakers and industry stakeholders seeking to promote sustainable building practices.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"502 ","pages":"Article 145363"},"PeriodicalIF":9.7,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675505","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}
