“…The current synergies between sustainability and CE concepts are investigated, and findings indicate that considering the circular supply chain concept for construction assets enables decision-makers to involve reusable materials for the new design development. One workable solution for this purpose is the CCEF, as developed by Dams et al (2021), which can quantify the circularity of materials entered into new buildings. Hence, the new design should include these materials to minimize waste and increase the salvage value.…”

“…Dams et al (2021) developed a circular construction evaluation framework (CCEF) that can quantify the level of circularity in a construction project using criteria specified in an accessible tabulated format. Ghaffar et al (2020) surveyed the UK construction industry to analyse the current barriers of Construction and Demolition Waste Management from the demolition sector’s perspective and revealed that components’ reuse could be improved if smart demolition and selective dismantling are implemented.…”

Purpose This paper aims to explore the emerging relationship between Industry 4.0 (I4.0) digital technologies (e.g. blockchain, Internet of Things (IoT) and artificial intelligence (AI)) and the construction industry’s gradual transition into a circular economy (CE) system to foster the adoption of circular economy in the construction industry. Design/methodology/approach A critical and thematic analysis conducted on 115 scientific papers reveals a noticeable growth in adopting digital technologies to leverage a CE system. Moreover, a conceptual framework is developed to show the interrelationship between different I4.0 technologies to foster the implantation of CE in the construction industry. Findings Most of the existing bodies of research provide conceptual solutions rather than developing workable applications and the future of smart cities. Moreover, the coalescence of different technologies is highly recommended to enable tracking of building assets’ and components’ (e.g. fixtures and fittings and structural components) performance, which enables users to optimize the salvage value of components reusing or recycling them just in time and extending assets’ operating lifetime. Finally, circular supply chain management must be adopted for both new and existing buildings to realise the industry's CE ambitions. Hence, further applied research is required to foster CE adoption for existing cities and infrastructure that connects them. Originality/value This paper investigates the interrelationships between most emerging digital technologies and circular economy and concludes with the development of a conceptual digital ecosystem to integrate IoT, blockchain and AI into the operation of assets to direct future practical research applications

“…The Circular Construction Evaluation Framework (CCEF) introduced by Dams et al [61] relies on the principles of Design for Disassembly (DfD) and Design for Adaptability (DfA) as keys to enhance the circularity of the building elements as well as the building itself as a whole. This happens by embracing a lifecycle perspective that allows future changes, e.g., disassembly, reuse, and reconfiguration.…”

“…It can be concluded that circularity in buildings can be incorporated at different yet interconnected scales: materials, products, systems, and building design. The most comprehensive requirements for circularity assessment in buildings are delivered by Dams et al [61], who took into account factors of life cycle assessment for materials and multiple factors for DfA and DfD, including varying durability of elements, prefabrication, connections, element reuse, and foundation design. However, the authors used these requirements to develop two levels of assessment, elementary and building levels, which are conducted separately.…”

A growing interest has been expressed in the issue of building adaptability over the past decade, perceiving it as an intrinsic criterion for sustainability. In light of the circular economy (CE) and its application in the construction sector, more attention has been paid to buildings’ design for adaptability (DfA) towards the realization of circular buildings. DfA is considered a key enabler for other circular design strategies such as design for disassembly (DfD), multi-functionality, spatial transformability, and design reversibility. However, implementation and assessment frameworks, and design-support tools for the circular building, are still in development as the characterization of circular buildings continues with endeavors to draw a defined shape by identifying the prerequisites for circularity where the design takes an important place. For the sake of objectifying the role of DfA in circularity frameworks in buildings, this paper carries out an analytical review and discussion on two types of assessment and design-support frameworks; the first addresses adaptability criteria and considerations in assessment frameworks that handle the concept individually while the second classifies existing circularity assessment endeavors into four main categories under which multiple tools are reviewed. A reflection on the scope and objectives for both types is later performed, illustrating the state of adaptability evaluation and criteria as well as its role in circularity frameworks. Results show that the concept of building adaptability lacks quantitative methods that quantify a building’s capacity to adapt as well as empirical data that prioritize the most valuable criteria facilitating adaptations. Moreover, many circularity assessment frameworks fail to consider adaptability criteria at all hierarchal levels of a building composition. To address this shortcoming, a series of conceptual considerations and requirements is proposed towards a potential establishment of an inclusive framework of a circularity design-support tool in buildings. The study is concluded by identifying gaps and recommendations for further developments in the field.

A circular economy requires closed circuits of consumed resources. Construction generates approximately 50% of solid waste globally, which is difficult to manage. The aim of this article was to identify the factors that determine the development of circular construction in the context of waste minimisation in the life cycle of building structures. The identification of cause-and-effect relationships by means of the DEMATEL method allows the problems of construction waste management to be taken into account in the context of the development of sustainable construction and fulfilling the principles of the circular economy.
