Leveraging Industrial Symbiosis for Circular Economy: Case Studies and Best Practices

Abstract

Industrial symbiosis (IS) is a cornerstone of circular economy (CE) strategies, enabling industries to collaborate by exchanging resources, energy, and by-products, thereby minimizing waste and optimizing resource use. This research examines how industrial symbiosis contributes to circular economy adoption, identifies best practices, and highlights lessons from global case studies. A mixed-methods approach, including surveys of 50 industrial clusters and in-depth interviews with 20 industry managers, was employed to evaluate the effectiveness of IS in emerging and developed economies. Findings reveal that industrial symbiosis significantly reduces raw material consumption, lowers environmental impact, and fosters economic resilience. Policy support, technological integration, and stakeholder collaboration emerge as key enablers of successful industrial symbiosis implementation.
