Digitalisation has revolutionised global supply chains, leveraging technologies like blockchain, AI, drones, cloud computing, and IoT. Among these advancements, digital circular supply chains (CSCs) have gained prominence for their potential to achieve sustainability and operational efficiency while fostering growth opportunities. This study provides a comprehensive review of digital CSCs, examining their applications, features, and implications across various sectors. By analysing recent research, the study highlights the integration of CSC principles with digital technologies to optimise resource and energy efficiency. Key findings suggest that digital CSCs minimise waste through superior design, technology integration, product reuse, and material recycling. The study also emphasises the need for a holistic approach to digital SCM to maximise its benefits. Offering valuable insights, this research outlines the advantages of digital CSCs and identifies future research opportunities to advance sustainability in supply chain practices.
