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).

However, available life cycle and techno-economic assessments for cultured meat production suggest that additional environmental and cost improvements are needed to compete with traditional meat production methods. 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. However, the impact of these undefined sources on cell production efficiency is largely unknown. The aim of this paper is to develop a novel exploratory supply chain model for a viable large-scale cellular agriculture network that considers facility location, ingredient blending, capacity design and technology selection problems. A bi-objective mixed integer linear programming model is developed to investigate the dynamics between demand, capacity design, location, ingredient blending and technology selection decisions as well as trade offs when optimizing for cost versus carbon emissions. Useful managerial insights are developed through various computational experiments, including modeling supply chain network design under deterministic and stochastic demand and the development of iso-cost curves to help decision makers design the optimal blending of chemically undefined byproduct ingredients with pure pharmaceutically sourced ingredients.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100152"},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190004","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 scoping review synthesises existing literature regarding social acceptance of the bioeconomy, including associated technologies, infrastructure and applications to provide insights into stakeholders’ decision-making process and influencing factors. Following Arksey and O’Malley’s (2005) methodological framework, this scoping review identified, selected, organised, and summarised 105 academic articles on bioeconomy acceptance across stakeholders. The findings indicate a strong geographical bias, with a concentration of studies in countries, such as the USA, Germany, and China, with countries in Eastern Europe underrepresented. The review also reveals the limited inclusion of some perspectives in the discourse. While a considerable body of research has been conducted on farmers, consumers, and the public, research on policymakers, industry leaders, and researchers themselves is less prevalent. Interestingly, studies on farmers mainly focus on their views on certain applications, i.e. as passive recipients of (potential) applications, rather than how they can actively participate in shaping the bioeconomy. Noting a reliance on survey methods, shifting to more participatory research methods could enhance stakeholder engagement. Furthermore, the conceptualisation of acceptance in the literature is predominantly passive to date, focusing on attitudes and perceptions, often in relation to concepts rather than tangible or real objects. As bioeconomy innovations become more common, research will need to shift towards understanding active acceptance, how people engage with and adopt these innovations in their everyday lives. This shift will be critical for building a bioeconomy that is sustainable, just and inclusive.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100157"},"PeriodicalIF":0.0,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144124436","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}

There is still a lack of studies on the application of black soldier fly larvae (BSFL) in treating OPW as a single-stream substrate under different preprocessing conditions. Thus, this study aims to bridge the gap between OPW treatment and the application of BSFL as a new waste treatment method and contribute to sustainable agriculture. Results from this study showed that OPW provides nutrients, vitamins and high sugar proportion that might help to increase the BSFL length (20.72 ± 1.13 mm) and weight (154.61 ± 4.78 mg), extend their lifetime in the larval stage (60 ± 2 days), with the waste treatment effectiveness was 82.1 % (± 1.5 %).

The volatile compounds, such as limonene in OPW, might not restrain the survival and growth of BSFL if a suitable feeding strategy is applied. Moreover, preprocessing of OPW (shredding and dewatering) helps to accelerate the decomposition process and maintain comfortable moisture content (79.23 ± 1.07 %), temperature (27.89 ± 1.20 °C), and pH (6.99 ± 1.73) conditions for the growth of BSFL rather than the unprocessed substrate. Besides, in treatment trays, the percentage of BSFL reaching pupae stage was 58.7 % (± 2.8 %) while this figure in the control tray was 85.4 % (± 1.5 %), meaning that the BSFL in treatment trays can continue to decompose the OPW as they are still in the larval stage.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100155"},"PeriodicalIF":0.0,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098933","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}
