The main aim of this paper is to demonstrate that clusters can support the sustainable development of rural areas through the creation of shared value. This is done via the close exam-ination of six different cases of rural clusters in Greece, Italy, Germany, Poland, Denmark, and Sweden. Qualitative as well as quantitative data were taken from the clusters, which demonstrated that their main business approaches naturally coincided with the creation of economic, social, and environmental benefits for the local communities in which they operated. The case clusters were created in a top-down manner, aimed at boosting regional R&D activities and making the local economy more competitive and more sustainable. However, private initiative took over and al-lowed these clusters to flourish because meeting the regions’ economic, social, and environmental needs successfully coincided with the target of the clusters’ own development and profitability. The results show that clusters, with their potential for shared value creation, can constitute a powerful engine for the revitalisation and development of rural areas, addressing the significant challenges which they are currently facing.

Action 2 of the European Union’s Updated Bioeconomy Strategy, i.e., “Deploy local bioeconomies rapidly across Europe”, promotes education and training in all member states. It is a fact that Greece has not yet adopted a national bioeconomy strategy, so stakeholders and farmers cannot benefit from its potential. The adoption of bioeconomy practices is now a prerequisite for receiving funding under the Common Agricultural Policy 2023–2027. Farmers unknowingly use some bioeconomy practices on their farms, and in this study, an attempt was made to investigate how farmers in the region of Western Macedonia would like to be trained in respect of the bioeconomy, knowing the opportunities it offers. The research was conducted through a structured questionnaire answered by 412 farmers from the region. The findings from the subsequent k-means cluster analysis show that farmers can be classified into three clusters: engaged, restricted, and partially engaged. The perceptions that predominate in each cluster are influenced by age, income, and the regional unit in which the farmers reside. In addition, the decarbonization of the Western Macedonia region influences their views and how they would like to be informed about opportunities arising from the bioeconomy. Limitations in this study include the fact that the sample consists only of farmers living and operating in a particular region. In addition, there is an urgent need for political will to establish a national strategy for the bioeconomy. The importance of the present study lies in the fact that few studies have addressed the training of farmers on bioeconomy issues either in Greece or internationally.

The development of the bioeconomy in the European Union is promoted through various policies. In Greece, however, there is a paucity of research on bioeconomy issues and policies at both the national and regional levels. This study systematically examines the feasibility of developing a bioeconomy blueprint within the context of a geographically isolated and mountainous region. By employing an integrated strategic framework combining sustainable resource management, innovation and participatory governance, the proposed framework emphasizes the transition from conventional, unsustainable economic practices to a contemporary development paradigm underpinned by the tenets of the circular economy and the utilization of local resources. A central tenet of the proposed framework is the enhancement of collaborative endeavors among local stakeholders, academic institutions, and business entities, with the overarching objective being the promotion of cutting-edge technologies and the economic diversification of the region. Concurrently, emphasis is placed on the necessity to establish conducive policies, regulatory frameworks, and financial mechanisms that will facilitate the development of sustainable industries and mitigate the environmental impact. The text emphasizes the importance of human resources development through educational and training programs, ensuring adaptability to the demands of the emerging bioeconomy. The study concludes that, despite the inherent difficulties arising from geographical isolation and limited access to resources, the region has the potential for sustainable development. The region’s capacity for sustainable development is contingent upon the implementation of suitable strategies and the mobilization of investment, which will be instrumental in the establishment of a robust and environmentally sustainable economic model.

Gasification is a promising and attractive thermochemical method for biomass-to-energy conversion, with fluidized bed reactors being one of the best options for large-scale operations. Olive residues in particular are potentially excellent candidate biomass fuels in the Mediterranean area, due to the region’s increased capacity in olive oil production. Herein, the gasification experiments of olive kernels in a 2 MWth air-blown, bubbling fluidized bed reactor located at CENER’s facilities (BIO2C) in Navarra, Spain are presented. Even though technical issues were demonstrated due to the operation of the plant with a high-density biomass fuel and given the scale of the process, a quasi-steady-state and isothermal 12 h operation at an equivalence ratio of 0.25 ± 0.03 was attained. Given the satisfactory experimental results, an Aspen Plus simulation model of the process was also attempted. Notably, the proposed methodology agrees well with the experimental results and can be regarded as a starting point in future studies examining the gasification of relevant biomass in a MW-scale unit. Next, the effect of equivalence ratio and residual biomass moisture content were also evaluated, with the scope of designing future experiments that require minor modifications in the already existing apparatus. Finally, a syngas utilization route through the provision of energy for district heating purposes in the nearby village of Aoiz was proposed.
