The latest Horizon Europe call targeting circular economy and bioeconomy sectors resulted in five brand new projects which will greatly contribute to the Circular Cities and Regions Initiative efforts and objectives. The projects CSS Boost, CircSyst, CisWEFE-NEX, FIC FIGHETRS and SOLSTICE will target various waste streams, industries and apply circular systemic solutions in cities and regions. As partner of CSS Boost, ACR+ brought these projects together for a session of getting to know each other and identifying initial synergy opportunities. This meeting also included representatives of previously approved and already running CCRI projects like DECISO and a representative of the CCRI Coordination and Support Office who briefed the project coordinators on the CCRI framework, structure and what support and valorisation schemes exist.
