On 31 May 2023, Coimbra hosted the second communication forum of the RN21 Integrated Project, dedicated to the certification Label and the technical magazine. The Consortium reached consensus on a Label authenticating Natural Resin from Pinus pinaster sourced from certified forests (FSC®/PEFC), valuing the national maritime pine. The need to adapt chain-of-custody standards for first and second transformation was also defined — a decisive step towards the future resinae brand.
