The BRIDGES project and the BERRY+ S3 industrial modernisation partnership have shared from the start focus on innovation, circular bio-based economy and value-chain based development. Thanks to the additional activities awarded to the BRIDGES project (2021-2023) and the value chain approach adopted in BERRY+, the Regional Council of Helsinki-Uusimaa (PP4 in the BRIDGES project and PP2 in the BERRY+) has brought together the two initiatives with its RIS3, and operationalised the linkages, in the sense of a new generation of planned activities. This approach is a demonstration of how regional authorities can experiment and benefit from and through interregional initiatives. We would like to share, briefly, the experience with our partners and the IE community, and possibly discuss it further. Please find an account of our approach here.
