The medical sector is lagging behind in adopting circular economy practices due to its heavily regulated operating environment. A lack of a framework for measuring circularity performance of large-scale medical equipment is one of the main challenges. To address this, a Circularity Model of Products & Spare Parts (CMPP) was developed by integrating three main features: adapted to the healthcare sector, data-driven automated model, and decision-oriented. The CMPP provides a systematic way to measure and track circularity performance of healthcare industries. It can also be adapted to fit other industrial systems and sectors. The research offers valuable insights into the potential of digitalization and data-driven culture in fostering the transition from linear to circular models both from conceptual and operational perspectives.
