Among concerns on sustainability and environmental protection, there is a growing interest in the adoption of circular supply chains (CSCs). This work introduces a firstcut approach to capturing the resilience of supply chains and their components related to material handling. We develop a methodology for computing the new equilibrium states after disruptions and use this to measure the resilience of circular supply chains. Numerical simulations illustrating our concept are performed on a synthetic toy-example. In addition, we introduce a secondary measure of resilience that encapsulates the transient stages of a supply chain after disruption. This measure is able to highlight the potential strength of CSCs over linear supply chains (LSCs) resulting from the circulation of reused materials. Despite the increasing hype in CSCs, caution is needed when analyzing its benefits over LSC. A CSC must be designed in way such that the positive effects of the CSC outweigh the negative effects.
