Abstract: The built environment is heavily dependent on wasteful linear economic models and needs to transition to the circular economy (CE). One of the key enablers of CE is Digital Product Passports (DPPs). However, determining the necessary information and selecting suitable technologies remains to be challenging in practical implementations. This research aims to present a framework for implementing DPPs using Knowledge Graphs (KGs). A literature review was conducted to identify the key components of the framework. The result shows that the key elements encompass use cases identification, data collection, modelling, integration, governance, access and querying, and maintenance and updating.
