Abstract
As industries worldwide face mounting environmental regulations and resource constraints, the integration of Circular Economy (CE) principles has gained prominence, with Industrial Symbiosis (IS) emerging as a key operational mechanism. IS facilitates the mutual exchange of materials, energy, water, and by-products among firms, thereby enhancing resource efficiency and minimizing waste. This study investigates the intersection of IS and Social Network Analysis (SNA), a methodological approach increasingly used to map and analyze the complex inter-organizational networks underpinning symbiotic exchanges. Employing a Systematic Literature Network Analysis (SLNA) framework, this research reviews and synthesizes 86 core publications to uncover prevailing themes, methodological trends, and network structures. The results highlight the growing sophistication of SNA applications within IS studies, revealing key metrics such as centrality, density, and tie formation that elucidate the dynamics of resource sharing. Furthermore, the analysis identifies dominant network configurations—such as core-periphery and decentralized clusters—that characterize successful IS systems. The study proposes a conceptual framework delineating the cyclical development phases of IS networks, emphasizing the critical roles of trust, information sharing, and stakeholder engagement.
