Using the PRISMA framework, 99 studies were analyzed to assess how LCA has been applied to evaluate the effectiveness of circular strategies. The findings reveal that Resource Efficiency and Waste Minimization (32.5 %) and End-of-Life Planning (27.8 %) are the most frequently assessed strategies. In contrast, Product Longevity (10.8 %), Circular Business Models (14.2 %), and Sustainable Materials (14.6 %) receive comparatively less attention. The construction sector (38 %) demonstrates the highest implementation of multiple circular strategies, followed by the automotive industry (32 %), where LCA has been instrumental in validating material efficiency and lightweighting approaches. While packaging and wind energy sectors show targeted applications of LCA in closed-loop systems and material recovery, industries such as textiles (8 %), chemicals (12 %), and marine applications (6 %) remain underrepresented. LCA plays a critical role in quantifying the environmental benefits and trade-offs of circular strategies, offering valuable insights into resource optimization, emissions reduction, and waste minimization. By assessing hotspots and performance metrics, LCA helps designers, manufacturers, and policymakers make informed decisions on circular interventions. However, methodological inconsistencies, data limitations, and the lack of standardized metrics for evaluating multi-strategy synergies hinder broader implementation. Additionally, certain strategies, such as Water Efficiency and Additive Manufacturing (2 % each), remain largely unexplored despite their relevance to circular economy objectives. To address these gaps, future research should prioritize standardizing LCA methodologies, expanding its application in underrepresented sectors, and developing a more structured approach to evaluating synergies between circular strategies. By offering a unified CDS classification and cross-sectoral synthesis, this review supports the effective integration of LCA in circular design practices and provides actionable insights for future research, industry application, and policy development.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"521 ","pages":"Article 146188"},"PeriodicalIF":10.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724242","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 aimed to maximize the efficiency of SA production from municipal household and restaurant food waste, by creating a multistep LFFW valorisation strategy. Thus, a parameter-optimized protocol for integrated hydrothermal pretreatment (acid or alkali) together with enzymatic hydrolysis of the LFFW was created. The highest monosaccharides concentration of 66.2 g L⁻¹ was achieved using 4 % sulfuric acid at 180 °C for 0.5 h, combined with enzymatic hydrolysis with amylase, cellulase, and cellobiose. However, due to direct enzymatic hydrolysis of the LFFW (monosaccharides concentration of 56.9 g L⁻¹), it could immediately be used for SA production without requiring additional downstreaming processes due to inhibitors (i.e., furfural, formic acid, and acetic acid). Subsequently, the comparison of SA production efficiency of <em>Actinobacillus succinogenes</em> 130Z, <em>Basfia succiniciproducens</em>, and <em>Actinobacillus succinogenes</em> CICC11014, using the LFFW hydrolysate as feedstock, showed that <em>A. succinogenes</em> 130z, had the higher SA production efficiency with a yield of 0.43 g SA g⁻¹ glucose. Finally, a further process optimization was realized by nutrients addition (i.e. yeast extract, NaHCO₃, Na₂HPO₄·2H₂O, and K₂HPO₄·3H₂O), achieving a 54 % higher SA production yield compared to the LFFW fermentation without nutrients addition. These novel multistep strategy of LFFW utilization, provides key insights for future SA production in food waste treatment facilities.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"521 ","pages":"Article 146270"},"PeriodicalIF":10.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719516","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}

Moreover, the carbon emission generation mechanisms at the component and material levels are lacking for ejection cooling systems. To address these issues, this paper presents a novel solar-powered adaptively coupled ejector-compression refrigeration system to reduce collector area and increase solar efficiency.

The study employed a qualitative research approach based on 18 in-depth interviews and two focus groups with stakeholders from primary and secondary marine industries (including equipment, packaging, biotechnology, and ingredients) in Iceland and Norway. Furthermore, an analysis of sustainability reports of the 17 largest seafood companies in these countries was conducted to examine current circularity practices and metrics. The qualitative data was analysed through the qualitative software MAXQDA using a grounded theory approach and the method of constant comparisons. The sustainability reports were manually examined, and key data was collated and compared in excel. Our findings indicate four key categories of institutional barriers—social, market, resource, and regulatory—that hinder circularity in marine value chains. The sustainability reports reveal a range of circularity initiatives that companies are voluntarily undertaking though reporting metrics need to be more standardised and waste data more accurately reported. These insights highlight critical areas for policy intervention and strategic management.

To address this issue, China has implemented a series of \"red line\" policies, with the objective of improving the efficiency of resource use. While the relevant strategies of a single resource may prove beneficial to a subsystem, they may have an ineffective and even negative impact on the Water-Energy-Food Nexus (WEFN) system. Therefore, it is imperative to quantify and improve the input-output efficiency from the perspective of the WEFN system. Research primarily calculates efficiency from a static perspective or network efficiency alone; however, few studies have simultaneously considered the dynamic characteristics and network structure of the WEFN system. In terms of drivers analysis, few studies have revealed the impact of factors on efficiency across time and space. To address these issues, this study proposed a dynamic network Data Envelopment Analysis (DEA) model that captures both subsystem interactions and intertemporal linkages. The model enhances measurement accuracy by integrating feedback mechanisms between water, energy, and food subsystems while incorporating capital stock dynamics across consecutive periods. Furthermore, a Geographically Temporally Weighted Regression (GTWR) model was employed to elucidate the spatiotemporally varying impacts of efficiency drivers. To illustrate the application of these models, this study conducted a case study in Guangdong Province of China. The results indicate that provincial efficiency followed an inverted U-shaped trend, increasing from 0.296 in 2010 to 0.731 in 2021, followed by a slight decline. Spatially, efficiency demonstrated a radial gradient, peaking in the Pearl River Delta and diminishing toward peripheral regions. Northern Guangdong emerged as the least efficient subregion, constraining overall system performance. Spatial autocorrelation analysis identified persistent positive clustering effects, though Moran's I values declined from 0.33 to 0.21, indicating reduced regional disparities over time. GTWR results highlighted urbanization level, technological progress, and environmental governance as positive drivers, while industrial development exerted negative impacts. These factors demonstrated significant heterogeneity, urbanization markedly benefited Western Guangdong, whereas technological and environmental interventions yielded the greatest improvements in the Pearl River Delta. These findings provide actionable guidance for differentiated policy formulation. Core regions like the Pearl River Delta require advanced circular economy strategies to overcome resource saturation, whereas peripheral areas necessitate targeted investments in infrastructure and innovation.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"521 ","pages":"Article 146244"},"PeriodicalIF":10.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719554","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 example, recognizing the opportunities in the global electric vehicle revolution, the Hungarian government has sought to attract lithium-ion battery manufacturing companies and establish a national battery industry with a globally significant production capacity. Consequently, Hungary is experiencing a rapid expansion of large-scale battery factories and related industrial facilities. However, concerns regarding the environmental, health, and social impacts of battery production—including the potential release of toxic chemicals and excessive use of natural resources—have incited public opposition. In the communities accommodating or assigned to accommodate battery factories, residents have increasingly expressed dissatisfaction, and civil society organizations (CSOs) have protested against the government's strategy. This has generated significant conflict between local communities and CSOs on one side, and authorities and local governments on the other.
