Leveraging Blockchain for Circular Economy: a Digital Product Passport Platform for BIM-based Design

Abstract: This paper proposes a tool integrating a BIM library plugin with a Digital Product Passport (DPP) system to support modular construction and circularity. DPPs store essential product data, includ-ing history, technical characteristics, environmental impact, and reuse potential, structured using Product Data Template standards compatible with BIM. The platform allows designers to access reusable products’ DPPs via the BIM library and import this data into their BIM models. By ad-dressing lifecycle information gaps, this system enhances sustainable decision-making, reduces waste, and leverages modular construction’s strengths in disassembly, recovery, and reuse to promote sustainability and a circular economy in the construction industry.
