The Ellen MacArthur Foundation, in collaboration with the Circular Supply Chain Network, recently published a white paper entitled Building a Circular Supply Chain. This publication addresses the transition from traditional, linear supply chains to circular ones, emphasizing the increased resilience they offer. Circular supply chains, characterized by distributed networks, multidirectional flows, and maximization of product and material use, provide a solution to the vulnerabilities of linear models. These supply chains not only help reduce greenhouse gas emissions and costs, but also minimize dependence on natural resource extraction. The white paper also highlights the key role of supply chain professionals in this transformation. They are responsible for managing the vast quantities of materials in the global economy and can influence the wider adoption of circular economy principles. The paper and an accompanying fact sheet highlight nine focus areas for supply chain leaders to facilitate this crucial transition, providing a comprehensive guide to redefining supply chains in today’s economic landscape.
