In the framework of the BIOCIRCULARCITIES (BCC) project, following the third round of Local Living Labs organized in March, the third Peer Review Session will be held in Barcelona on 23-24 May with the participation of international bioeconomy experts. Results on barriers and drivers for implementing circular bioeconomy at local level and the preliminary results of the LCA and LCC of the alternative scenarios selected for each pilot will be presented and discussed. A dedicated session to test the BCC webtool prototype will be organized to receive relevant feedback from the international reviewers. In addition, representatives of other European projects (WAYSTUP, BIOBOOST and BIOBEST) that have synergies with BCC will be invited to present their project outcomes relevant to BCC and discuss future possible partnerships.
