In the conference "Circular Procurement: time to scale up!" in Brussels on 11 May 2023, the Interreg ProCirc partners invite public and private procurers, circular procurement experts, (sustainability) managers from procuring organisations, value chain representatives, and national and EU policy makers on Circular Economy and Procurement to learn from their experience, and together explore how to scale up. Throughout the day there is ample opportunity to meet, discuss, and share thoughts on circular opportunities and challenges.
