This study aims to identify characteristics, trends, and opportunities of the bioeconomy transformation in the RR. Semi-structured expert interviews and a qualitative content analysis were carried out utilizing a comprehensive evaluation framework to identify key factors influencing the transformation. While stakeholders view the transition positively, challenges such as institutional guidance and stakeholder involvement persist. Recommendations such as the stakeholder-driven development of a regional vision and roadmap and the development of a biodiversity protection strategy and corresponding monitoring system aim to enhance the transformation process. These recommendations also provide guidance for regions undergoing similar changes, although locally-specific socio-economic conditions must be taken into account.</div></div>","PeriodicalId":100394,"journal":{"name":"EFB Bioeconomy Journal","volume":"5 ","pages":"Article 100074"},"PeriodicalIF":0.0,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143128480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cultivation process, from early-stage batch cultures to modern raceway pond systems, highlights the importance of optimizing operational parameters such as light, temperature, nutrients, pH, and salinity. The article also examines the challenges of contamination, mixing dynamics, and the effects of shear stress on microalgae growth. Recent advancements in raceway pond design, including improved agitation mechanisms and hydrodynamic models, are discussed to enhance biomass productivity and cultivation efficiency.

Here, we calculated the potential of microalgae for the capture of CO<sub>2</sub> by integrating it with a large emitter (gas-based energy plant) and a low emitter (dairy farms), and also discussed if such integrated systems can be considered as carbon sequesters given that the final use of the biomass often quickly releases the captured CO<sub>2</sub>. Moreover, the CO<sub>2</sub> footprint of microalgal systems is highlighted as a critical point of attention for future developments.
