“…As stated, most of the work on material passports in the construction sector focused on developing material passports at a building level Heisel and Rau-Oberhuber, 2020;Kedir, Bucher, and Hall, 2021). However, from a circular perspective, the material passport should have additional information to support city-level activities such as urban planning (Herthogs et al, 2012;Li, Quan, and Yang, 2016).…”

Material passports have been proposed to collect, store, and share material information to promote circularity in the construction sector. However, the current recommendations for material passports focus on material information at a building scale with little attention to its implications on a city scale. To address this limitation, this paper provides directions for developing a material passport ontology that could be used to collect, store, share, and retrieve data at multiple scales of abstraction. It describes the requirements for a material passport ontology and provides recommendations for integrating existing ontologies. This paper is relevant to researchers developing information management platforms to enable a circular economy

“…Further linked-data technologies have also been used in the city scale for decision-making during city planning (Chadzynski et al, 2021;. Also, ontologies have been used to develop material passports to enable circular information flow in Industrialized construction (Kedir, Bucher, and Hall, 2021).…”

“…The traditional construction industry is not currently equipped for the transition. That being said, approaches such as modularity in construction and industrial practices have been found to help promote the transition [7,10,11,12]. Industrialized Construction (IC), referring in this case to concepts such as modular building, prefabrication, robotics, and off-site manufacturing, offers tremendous opportunities for reducing environmental impact [7,13].…”

A circular economy offers a solution for improving both the efficiency and environmental impact of the built environment. As the construction industry transitions to a circular economy, adequate information flow is necessary to keep products in the value chain for as long as possible. Industrialized construction firms show high potential for a successful transition to a circular economy because of optimized information flow through the use of product platforms, the use of information communication technologies, and the integration of actors. However, there is no current framework to assess whether construction firms using industrialized construction methods have a circular information flow. In this research, four characteristics are identified as main descriptors of a circular information flow framework: Completeness, Availability, Accessibility, and Incorporation of Information into Business Strategy. Using the framework, industrialized construction firms are asked to self-assess their performance through pre-defined survey questions. The findings from sixteen industrialized construction firms reveal the need for more complete data about recyclability potentials of products and unique materials and product identifiers, with 47% of firms indicating they have insufficient information. The survey of companies also indicates a need for more feedback about the reuse, recycling, and remanufacturing phases to be available, with only 20% of firms gathering feedback about reuse, 13% about recycling, and 20% about remanufacturing. The stakeholders with the most consistent access to information about design and materials of a project are the manufacturer, engineer, architect, and assemblers. 13% of firms employed RFID tags. More accessibility of information is needed for actors outside of the firm. Additionally, only 13% of firms implemented a take-back strategy, emphasizing the need for incorporating these business strategies within the firm. 17% of firms, however, had CE in mind during strategic development, demonstrating the potential for CE adoption in industry. Finally, the paper discusses future opportunities for circular information flow, such as employing blockchain technology.

This chapter offers a comprehensive analysis of the intersection between digitalisation and the circular economy (CE) within the construction sector. It underscores the transformative potential of integrating digital tools to advance circularity objectives across managerial, environmental, economic, and social dimensions. The chapter discusses fourteen digital tools and technologies, which play a pivotal role in CE by streamlining data integration and visualisation, enhancing the accuracy of Life Cycle Costing (LCC) and Life Cycle Analysis (LCA) assessments, and supporting the adoption of CE strategies. Moreover, it explores how digital tools can facilitate collaboration among stakeholders, fostering knowledge sharing and effective communication throughout the project lifecycle. Nevertheless, challenges such as the absence of standardised methods, data interoperability issues, and the need for well-defined system boundaries remain. The chapter highlights the critical role of digitalisation in advancing the transition towards CE in the construction sector, emphasising the necessity of overcoming technical and systemic obstacles to fully harness the potential of digital tools in implementing CE. This transition aligns with the broader ambitions of the European Green Deal and the EU Digital Strategy, aiming to create a more sustainable, efficient, and resilient construction industry. By addressing these challenges and leveraging digitalisation, the construction sector can make a significant contribution to a sustainable and circular economy, ultimately benefiting both the environment and society.
