Recently circular economy is gaining momentum in the political and academic agendas. However, little is known from the managerial practice about the configurations, dynamics and coordination mechanisms of the circular economy supply networks. Aiming to fill this theoretical and practical gap, this study employs multimethod approach, developing three interrelated articles: a systematic literature review, a variance and process multiple case study (of seven circular supply chains of different industries), and system dynamics modelling. As main contributions we present in article 1 a supply chains typology related to circular economy, a set of supply chains management strategies and tactics to implement circular economy. In article 2 we present a conceptual framework to circular economy supply network management, with three key elements: management mechanisms, internal and external environment, and emergent properties, with three sets of propositions. Explaining, that a multi-tier supply network management and external stakeholders may lead it to a hybrid loop configuration, a closed loop and open loop combined, dynamically adapting to internal and external environment changes. We also introduce two types of leverage points, related to agents role and position in supply networks, one related on which agent initiates post consumption product or byproduct physical reverse flow and one related on which agent coordinates this activity. Finally, in article 3, we suggest an over time circular economy supply network transition phases management model, with the respective circular factors and cooperative and competitive challenges for managing it from its pre-development to self-renewal or decline. We also present a dynamic strategy tool to manage supply chain circularity for academics, policymakers and market practitioners, modeled by system dynamics, simulating the impact of supply network management key variables (multi-tier supply chain management, hybrid leadership, circular flows coordinating and initiating mechanisms) on its circularity performance.
