The concept of circular economy has emerged as a driver to sustainability. Recent studies suggest that circularity can also promote supply chain resilience. In literature, few works are investigating how the transition towards circular supply chain can enhance the ecosystem viability. The purpose of this paper is to compare the performance of linear and circular supply chain in term of resource management and risk mitigation. A simulation-based approach is adopted to assess the performance of each configuration through a case study of two supply chains operating autonomously and collaboratively. The findings indicate that the circular practices promote resource and waste management. However, the outcomes underline the vulnerability of the circular network to risks. The results provide valuable insights for scholars and professionals in promoting knowledge regarding the transition toward the circular ecosystem.
