Targeting a South African context, CE-related South African policies, guidelines and national initiatives were evaluated to capture the local socio-economic context. Consequently, a relevant CE definition was formulated for the South African agrifood industry, prioritising social sustainability contributions and activities targeting natural system regeneration. Literature related to existing CE measurement frameworks and their applicability to agrifood systems was reviewed, considering the wine industry as an example agrifood system. It highlighted the insufficient consideration of energy efficiencies, circularity of biological components and nutrients, and social sustainability impacts as current shortcomings. Future research should address these gaps to allow for the comprehensive evaluation of circularity in agrifood systems. Additionally, developing a standardised methodology for selecting, scaling, weighting and compositing indicators is recommended.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100169"},"PeriodicalIF":0.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144780350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the link between agricultural progress and carbon emissions across spatial and temporal variations in China. The findings reveal that improvements in agricultural practices tend to decrease both carbon emissions and their intensity. However, the short- and long-term effects differ notably. In more agriculturally advanced areas, emissions are reduced, showing an inverted U-shaped relationship between agriculture and carbon emissions in the eastern and central regions. In contrast, the western and central areas still faced potential increases in emissions. Additionally, agricultural progress has a significant spatial dimension on carbon emissions. In the short term, neighboring regions contribute considerably more carbon emissions than local agriculture. However, advancements in agriculture reduced emissions in nearby areas over time, and long-term agricultural progress has greatly reduced carbon emissions in surrounding regions. Although exploring strategies can help reduce emissions in agricultural settings, the reductions achieved through these approaches only partially offset the overall carbon emissions resulting from agricultural progress. Therefore, providing inclusive financial support is crucial for driving efforts to reduce agricultural emissions.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100167"},"PeriodicalIF":0.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144780311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this the literature gap, the present study sought to identify and categorize young individuals in Indonesia into more homogenous groups based on socio-demographic characteristics and food wasting behavior. To this end, Principal Component Analysis (PCA) and Cluster Analysis (CA) were employed. The data were collected through an online survey of young individuals aged 16–30 across Indonesia as respondents, resulting in a total of 481 respondents. The study’s finding indicate that the combination PCA and CA is a viable approach for the identification and clustering of young individuals in Indonesia, with the basis of the identification and clustering being their socio-demographic characteristics and their behavior concerning food waste. This study underscores the heterogeneity among young Indonesians with regard to their food wasting behavior and socio-demographic characteristics. The analysis yielded three distinct clusters: Cluster 1, \"students who care about food waste\", Cluster 2, \"students who do not care about food waste\", and Cluster 3 \"young workers who care enough about food waste\". Specifically, no significant differences were found between clusters with regard to gender and the predominant method of food provisioning. A comparison of clusters reveals significant differences in the variables of age, educational attainment, occupation, income, food expenditure, and the frequency of food wastage. The differences among clusters provide crucial insights to support initiatives aimed at curbing food waste by addressing issues of heterogeneity. The distinguishing characteristics of clusters in the younger generation require alternative strategies and distinct policy recommendations, as outlined in this study.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100165"},"PeriodicalIF":0.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using biochar, a renewable and low-cost carbonaceous material produced from biomass waste, is an eco-friendly and clean technology to enhance soil health and address the energy crisis in agriculture. Hence, a comprehensive study of scientometric analysis of the use of biochar in agriculture was carried out using scientific literatures. Based on information collected from the Web of Science (WoS) database between 2001 to 2021, this work performed bibliometric visualization analysis using appropriate data sets of keywords to examine the new research trends on the application of biochar in agriculture. The number of scientific research examining the use of biochar in agriculture has significantly increased in recent years. A total of 4194 publications related to the use of biochar in agriculture were identified from the 2001 to 2021. Based on scientific data (WoS), the progress of biochar research was visualized using co-occurring analysis to identify the current scientific research trends, technological impact, and research gaps related to biochar. The scientometric study indicated that among the top 20 nations, the highest publication (44%) on biochar was produced by the People's Republic of China (PRC), followed by the USA (16%) and Australia (7%). Results showed that the majority of scientific research and development on biochar application in agriculture were accelerated after 2010 and the total research output in terms of publications was significantly increased from 42 (2010) to 882 (2021).

The adoption of circular supply chains has been found to improve the economic and environmental outcomes of production processes. The use of agricultural and food byproducts, such as hydrolyzed soymeal, as a source of amino acids has been identified as a way to reduce cost and environmental impacts.
