The Circular Economy is increasingly recognized as a critical approach to addressing the challenges of resource constraints and environmental sustainability in manufacturing. Despite this recognition, the practical integration of circular principles into manufacturing processes remains limited, partly due to a lack of required employee competences and skills. Learning Factories have emerged as an effective learning environment for competence development, providing realistic products and processes to teach methods and demonstrate technologies for value creation. This study aims to identify key fields of action for advancing Learning Factory concepts specifically for circularity through a two-stage survey conducted with Learning Factory operators. The findings reveal that Learning Factory design should prioritize the dimensions of process and product, with a focus on Remanufacturing operations. Furthermore, the results suggest that interdisciplinary aspects of the topic CE should be incorporated and a continuous best-practice exchange with other Learning Factory operators is crucial for the holistic remodeling of existing Learning Factories for circular manufacturing. These insights offer a foundation for future research on remolding of Learning Factories for ultimately supporting the transition to circular value creation in manufacturing.
