This chapter investigates the role of digital technologies in enabling the transition towards a circular economy, a model focused on sustainability by emphasising resource efficiency, waste reduction, and environmental regeneration. The study aims to bridge the gap between traditional linear economic practices and the emerging digital circular economy. The chapter employs a comprehensive literature review, examining the integration of digital tools such as the Internet of Things (IoT), artificial intelligence (AI), blockchain, and big data analytics in various industries, including manufacturing, agriculture, and energy. The study also explores case studies that highlight practical implementations of these technologies in promoting sustainable practices. The findings reveal that digital technologies significantly enhance resource optimisation, increase transparency in supply chains, and foster sustainable business models. However, challenges such as the high costs of digital infrastructure, the complexity of transitioning business models, and the environmental impacts of digital technologies themselves remain barriers to widespread adoption. This chapter contributes to the literature by providing a holistic view of how digital innovations can support the circular economy. It underscores the potential for digital technologies to drive sustainable growth while also identifying the challenges that need to be addressed for these technologies to realise their full potential in supporting a sustainable and equitable future. The study offers valuable insights for academics, corporations, and policymakers striving towards sustainability in the digital age.
