Abstract This study explores the transformative potential of industrial symbiosis (IS) in converting waste into valuable resources, thereby enabling energy-efficient circular design. It emphasizes IS's critical role in enhancing resource efficiency, reducing industrial waste, and conserving energy central tenets of the circular economy and key drivers for achieving the United Nations Sustainable Development Goals (SDGs). The research bridges a vital gap between policy and practice by analyzing the scalability of IS in developing and transitional economies, where systemic integration remains limited. It investigates how IS fosters cross-sectoral collaboration across industries, regions, and countries by creating networks where by-products and waste streams are exchanged to minimize environmental impact. The study also evaluates the role of enabling policy frameworks, digital technologies, and circular design strategies in accelerating IS adoption. It further demonstrates how advanced materials and real-time data infrastructures can streamline resource flows and optimize inter-firm synergies. Drawing from multiple international case studies including Kalundborg (Denmark), CNPC (China), Ulsan (South Korea), and Dalian Eco-Industrial Park the findings reveal substantial reductions in resource waste and energy use, with some systems achieving efficiency gains of up to 30%, validating the practical benefits of IS across diverse industrial contexts. However, the study also acknowledges key limitations, such as high initial investment costs, regulatory inconsistencies, and the need for trust-based collaboration across stakeholders. Ultimately, this research advocates for a holistic implementation framework that integrates governance, technological innovation, and circular design to support the transition toward a regenerative, low-carbon, and resource-resilient industrial future.
