The convergence of digital transformation and the circular economy is reshaping how industries approach sustainability, resource efficiency, and economic growth. This integrated review explores the role of digital technologies—including the Internet of Things (IoT), Artificial Intelligence (AI), blockchain, big data analytics, and cloud computing—in enabling circular economy principles across various sectors. By analyzing existing literature, the study identifies key drivers and challenges in the digitalization of circular practices, such as supply chain transparency, product life cycle extension, and closed-loop systems. The review also highlights opportunities for innovation, collaboration, and policy development that support scalable and sustainable business models. Findings suggest that while digital tools offer immense potential to accelerate circularity, barriers related to interoperability, data privacy, and infrastructure readiness must be addressed to unlock their full impact.
