In particular, we assess how the policy mix reacts to blocking mechanisms that hinder system functioning by studying the bioeconomy in Germany through the lens of the Technological Innovation Systems. In this regard, we analyze the policy mix elements introduced between 2006 and 2024 along three core blocking mechanisms, which we labelled as: Market Uncertainty, Policy Uncertainty, and Feedstock Uncertainty. The results reveal that the policy mix reacts to the identified bottlenecks by adding new or updating existing elements over time. These measures are yet mainly soft policy instruments. The policy mix will benefit from stricter instruments to foster the transition more substantially.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100154"},"PeriodicalIF":0.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144167700","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}

However, its success relies on broad social acceptance, making it essential to understand stakeholders’ perspectives to develop innovations that address societal needs. 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}

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":"2025-05-17","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}

Approaching design students to the concept of biophilia, based on the intrinsic connection between humans and nature, could help address this gap and facilitate the transition toward a holistic view of sustainability.

This highlights the necessity for detailed case studies. This research evaluates controlled environment agriculture within Qatar, comparing centralized greenhouses to decentralized vertical farms against the backdrop of the region’s distinct environmental challenges. By examining the capital and operational costs, including the critical factor of transportation expenses, the study offers an in-depth economic analysis of both systems. Dynamic analytical models for energy, water, and CO₂ utilization have been developed for greenhouses and vertical farms, to accurately estimate the respective resource usage in each cultivation system. The distribution cost, relevant for the greenhouse scenario, was evaluated using a vehicle routing problem. The findings reveal that greenhouses, with levelized cost of production of $3.19 per kg for tomatoes, offer a more cost-effective solution in Qatar’s specific context than vertical farms, which show a higher cost of $3.77 per kg Although greenhouses currently offer a more cost-effective solution, future studies should incorporate other context-specific factors, including ecological impacts such as water usage, which is particularly critical for regions like Qatar.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098888","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}

In the context of the exponential growth in demand for this specialty crop that suffers from limited shelf life, it is imperative to expand raspberry cultivation by employing sustainably-sourced production models. In the current study, we used Cyprus as a case study that is characterised by increased production costs and lack of year-round production despite the fact that the latter is feasible under different production systems and cultivation methods in different altitude-related meso‑climates. Towards that goal, the current study assessed the life cycle environmental impact and life cycle costs of two different cultivation methods - open-field production that took place from May to November 2022 and protected cultivation in high-tunnels, from August 2023 to April 2024, using in both cases the same cultivar (Kwanza®) and plant type. The results indicated that protected cultivation has better environmental performance (3.7 mPt - milli eco-points - per kg of raspberry produced compared to 7.4 mPt for open-field production). Noteworthy, production cost is excessive and substantially higher compared to other countries; open-field production has a life cycle cost of 22.5 €/kg, while protected cultivation achieved a lower life cycle cost, equal to 14.0 €/kg yet still high. From an output perspective, a key observation is the increased yield of raspberries in protected cultivation as well as the enhanced water use efficiency of the crop, due to a reduction of the water footprint by 76 %. It is also important to highlight the increased harvest efficiency of the crop under high tunnel, with 500 g per plant compared to 350 g on open field cultivation. Hence, it is safe to conclude that despite the increased start-up costs and knowledge-intensive practices, the productivity of the crop is increased during the off-season months, that can be sold for a premium. The results highlight the environmental and economic impact of the two cultivation methods and will be useful for producers and crop advisors seeking to expand the raspberry cultivation in climates that resembles south-eastern Europe and are characterised as vulnerable to adverse climate change scenarios.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"11 ","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947127","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}

Despite extensive studies on the impacts of coffee farm management on biodiversity, the trends in research on this issue over the last two decades remain unclear. Therefore, this work was initiated with the aim of conducting a systematic evidence map study concerning the impacts of coffee production on biodiversity throughout tropical coffee-producing countries. After conducting a search of the literature in peer-reviewed journal databases and gray literature, we screened the identified papers using machine learning-related software, identifying a total of 292 studies for inclusion in the systematic map database and synthesis. We found that there was a trend for an increase in the number of publications examining the relationship between coffee cultivation and tropical biodiversity, with the majority of studies being conducted in Latin America. Among coffee management interventions, studies on the effects of land-use gradients driven by coffee cultivation and shade management on invertebrate biodiversity were identified as dominant topics.
