The transition towards a circular economy model offers the opportunity to make the production system more sustainable and competitive. The transition to a circular structure requires several changes in product design, in market and business models, in methods for converting waste into resources, in the consumption model. All this requires systemic change and strong innovation. A production system based on the circular economy requires an effective model of governance and must involve all actors who contribute to its definition: policy makers, public and private research bodies, enterprises and citizens.
