Extensive studies have looked at the impacts of land use change (LUC) for oil palm expansion on biodiversity, but very few have quantified the impacts on ES in growing palm oil producing regions like Africa. We mapped and quantified the impacts of oil palm expansion on carbon storage, soil retention and nutrient retention ES in a palm oil producing region of Cameroon. We used the ESRI Sentinel-2 2017 10 m and ECJRC 2015 1 km Land Cover maps with InVEST models to assess the impacts of LUC for oil palm on ES. We found that present-day oil palm expansion has reduced carbon storage by 0.6 % from a “pre-cultivation” baseline scenario and will likely further reduce by 3.7 % and 6.8 % with 2 km and 4 km expansion. Soil retention is reduced by 0.2 % present-day and will likely reduce by another 5.5 % and 13.9 % while nutrient retention is reduced by 8.4 % and will likely reduce by 22.0 % and 40.4 % with 2 km and 4 km expansion respectively. Such information is necessary to understand the conservation of these ES in light of future oil palm expansion.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100176"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144908516","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}

They produce high quality fatty acids, amino acids and pigments, which can be utilized as ingredients across various industries. However, energy-intensive dewatering and drying technologies remain a significant barrier to cost-effective, large-scale microalgae production. This review aims at providing insights on how to possibly overcome such barriers, to enable and promote large scale industrial uptake of microalgae. Hereby, it summarizes current dewatering and drying methods, discussing their benefits and limitations. Pathways that can help overcome these barriers and enable industrial microalgae production are then discussed. Principles such as process optimization, exhaust drying heat recirculation, heat pump integration and industrial symbiosis are viable pathways that can enable industrial applicability. The review also presents how industrial side-streams, like wastewaters, excess heat and fume gas can be utilized in circular ways to promote cost-effective production and increased sustainability of different industries. The review aims to complement existing literature on microalgae harvesting, by adding and highlighting the importance of scaling-up and the necessity of removing barriers related to high production costs to achieve a sustainable circular economy. These insights into currently applied technologies and possibilities for industry symbiosis are beneficial for researchers, policymakers, and industry stakeholders striving to align microalgae production with the United Nations Sustainable Development Goals (SDGs), particularly SDG 7, SDG 12, and SDG 13, by offering practical pathways to reduce energy demands, promote circular economy principles, and mitigate greenhouse gas emissions in industrial systems.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100184"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145157065","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}

Numerous biological methods have been applied to treat the peel waste and gain by-products, yet the costs are still high, and there are leftovers to be treated. 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 highest growth was noticed in the OPW-NS-ND control (Tray 2). 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":"2025-12-01","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}

Many consultancy reports and academic and community-based studies have been conducted about the role and benefits of biogas in Southern Africa. Focus areas range from an introduction to biogas technology and its awareness by end-users, suitable feedstock and types of digesters, capacity building and project development, investors’ appetite and types of funding mechanisms available, and more. Synonymous outcomes from these reports indicate that biogas projects not only address energy access but also organic waste management challenges; they also spur localised skills development and employment opportunities across the value chain. However, with all these insights, biogas project development remains challenged – particularly the project’s sustainability. This study reviews secondary data of planned and implemented demonstration biogas projects supported by the United Nations Industrial Development Organization (UNIDO) in South Africa over a 6-year period. Findings indicate that the majority of the projects were intended for energy generation, followed by waste management and, in some cases, a concurrent focus. An important discussion point for the industry and developers is that: there are many components of a biogas project development cycle; for projects to be more sustainable, these need to be better interlinked. The components are: Component 1 (Capacity Building and Technology Support System), Component 2 (Biogas Market Development and Regulatory Framework), Component 3 (Technology Demonstration) and Component 4 (Scaling Up). The findings stress the need for greater knowledge-sharing of demonstration projects to serve as practical information for improved project development as well as sustainability.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100193"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145617568","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%).
