The global transition from a linear "take-make-dispose" economy to a regenerative, circular model has gained significant momentum in recent years due to increasing environmental degradation, resource scarcity, and stakeholder pressure for sustainability. At the heart of this transformation lies the concept of smart supply architectures digitally enabled, interconnected systems that facilitate real-time decision-making, resource optimization, and circular value creation across supply networks. This review paper systematically examines the intersection of digitalization, sustainability, and circular integration in supply chains, focusing on how advanced technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), blockchain, digital twins, and cloud computing are reshaping traditional supply chain models into intelligent, adaptive, and regenerative systems. We first explore the theoretical underpinnings of the regenerative economy, circular economy principles, and digital transformation in supply chain management. The paper then goes deep into architecture of the smart supply systems and its elements, followed by the role of cyber-physical systems, data-driven platforms, and interoperability frameworks. We also examined the role digital tools play in these three pillars of sustainability (environmental, social and economic) through understanding how digital tools are used to facilitate closed-loop, lower carbon footprints, improved traceability, and ethical labour practices. In order to give practical solutions, real case studies are explained on the companies that have been successful in the implementation of digital-circular models. With these achievements, there remains a great progress to be made with challenges such as technological silos, implementation cost being expensive, regulatory fragmentation, and cultural resistance being a challenge in each and every organization. These barriers should be tackled with an inclusive approach integrating technological innovations, policy change, inter-sector coordination and capacity development. The paper ends with the discussion of future research and policy opportunities in the construction of scalable, inclusive, and resilient smart supply systems that will enable the goals of a regenerative economy in the long run.
