The integration of Circular economy (CE) practices with Industry 4.0 (I4.0) technologies has significant potential for advancing suitability goals across various industries. This study explores the synergies between CE and I4.0 technologies, focusing on their role in enhancing waste reduction, resource efficiency, and sustainability. While CE aims to decouple growth from resource consumption and close loops, the adoption of I4.0 technologies such as Big Data, Artificial intelligence, and Robotics can optimize operational processes and improve decision-making. However, research on the systematic integration of these concepts remains limited. This study proposes a conceptual framework that bridges the gap between CE and Sustainable Performance (SP), moderated by I4.0 technologies. By highlighting their combined potential, the framework provides a structured approach to achieving sustainability across the micro, meso, and macro levels of CE, as well as the economic, social, and environmental dimensions of SP. The paper contributes to the literature by providing new insights into how I4.0 technologies can enhance CE practices and foster long-term suitable outcomes, while addressing critical gaps in the integration of these concepts within various industrial sectors.
