Most Circular Economy projects have focused on ‘how’ to produce circularly but not really on ‘what’ or ‘how much’ to produce. The ‘what’ question relates to issues of democracy, participation, gender and global justice that are in turn  connected  to  the  capacity  of  any  society  to  reflect  about  what  kind  of  technological  futures  its members desire. The conviction underpinning the JUST2CE project  is that the success of a transition towards a sustainable Circular Economy does not merely depend on the development of new technologies – artefacts or processes – but also in the reconfiguration of the governance of productive processes into more democratic and participatory mechanisms of designing and managing technology.
