Certain barriers to CE adoption in BCDW management are often peculiar to the core practice and structure of BCI. Hence, they are distinct and unique relative to other sectors. However, some barriers still cut across other sectors like coffee and textile. Therefore, it is necessary to provide some comparison of how the barriers to CE in BCDW differ from or are similar to that of other sectors. For example, the fragmented nature of BCI, lack of demolition record and data, inadequate demolition auditing, and lack of disassembly information are barriers that are quite special to CE adoption in BCDW management. Despite the imperativeness and the uniqueness of the barriers to CE adoption in BCDW management, there still exist some barriers that cut across other sectors. Barriers under the umbrella of policy, information, awareness, and technology in BCI also apply to coffee, textile, and mining sectors (Kirchherr et al., 2018; van Keulen & Kirchherr, 2021). Lack of guidelines and policies and lack of government support for CE are found not only in the BCI but also in the mining, food, plastic, and textile sectors (Hartley et al., 2022). Moreover, it is generally acknowledged that in managing waste in a CE in any sector (coffee, textile, mining, food, plastic, and leather), lack of CE model, fear of the outcome of shifting to a CE, lack of market for secondary products, lack of appropriate CE technology, lack of CE standards and lack of consensus on the CE indicators are common barriers.The distinction between the technology and information-related barrier (with the highest interaction) as indicated in Fig. 7 revealed that the success of CE in this dispensation must be grounded on innovative technologies and clear information on success factors, benefits, operational procedures, and innovative strategies to boost CE adoption and implementation in BCDW management(Rios et al., 2021). Institutional and regulatory-related barriers also is very prominent (based on interaction with other clusters of barriers). According to Mahpour (2018), the absence of regulations, policies, standards, and manuals supporting CE in the management of waste in BCI in many countries is an entrenched problem causing persistent dominance of the linear economy system. Adoption of CE could be mandated via laws and policies but also various conditions and factors must be integrated to make CE adoption possible and worthwhile (Bilal et al., 2020).Technological and information-related barriers may be mitigated through the collective commitment of academic institutions, ICT organizations, construction materials experts, government, and technical institutions (Rios et al., 2021). The ICT sectors, academic institutions, and government must work together towards the development of advanced technologies for CE adoption in BCDW management. Huang et al. (2018) argued that funding research for the development of innovative technologies that will promote CE in BCI is a powerful driving strategy. The capacity of practitioners in the industries should be improved in CE management skills and the required technologies (Aslam et al., 2020; Udawatta et al., 2015). This could be possible through CE seminars, enlightenment, workshop, and the provision of incentives for training and acquisition of technologies for CE in BCI (Ajayi et al., 2015). From the university level, integrating CE into university curricula could be a way to combat the information-related barriers (Mahpour, 2018).Organizational-related barriers can be addressed by the government and industrial practitioners (Mahpour, 2018). The various organizations responsible for CE development in the BCI must work hand in hand to ensure that their organization structures agree with the CE initiatives. This could be possible by consolidating the fragmented subsections of all concerned organizations, especially the BCI. According to Ajayi et al. (2015), driving strategies for CE under the organization category include (i) BCI restructuring to support CE; (ii) integration of fragmented sections of BCI; (iii) BCI personnel commitment to BCDW reduction and management; (iv) top management support for CE development; (v) incentive for CE development.Theoretically, this research demonstrated the complexities of the constraints preventing CE widespread adoption in BCDW management. The research contributes to the literature by analyzing and mapping the holistic connections among the barriers. Particularly, the findings contribute to CE literature by shifting attention from the overall BCI to the BCDW management which is a particular issue in the urban sector and the natural environment. Practically, the study strengthened the need to adopt integrated strategies and enablers to mitigate the barriers and recommended some effective approaches for the various categories of barriers. The results of this study will also help practitioners and decision-makers to understand the key barriers that must be overcome to improve better CE transition. The developed integrated framework could help decision-makers understand how the barriers are interconnected with the CE system. The implementation strategy was developed to serve as a recommended guideline to help management overcome the barriers and promote the implementation of CE in BCDW management. Therefore, this study provides a comprehensive view of the barriers to CE adoption in BCDW which was lacking prior to this study. Ultimately, the outcome of this study has a significant contribution to sustainable production and consumption, waste management, and cleaner production in the BCI and urban sector generally This study also calls for stronger fostering of efforts by the public and private organizations, and the research institutions to solve the challenges of CE adoption in BCDW management through innovative research and funding.

N2 - Waste generated by building construction and demolition (BCD) activities contributes to the major proportion of urban solid waste. A large amount of the waste is still sent to the landfill or downcycled globally. The adoption of circular economy (CE) in the building construction industry (BCI) could leverage significant gain in managing the waste from BCD activities. While studies have been conducted on CE in the BCI, a comprehensive review of the barriers to CE adoption in building construction and demolition waste (BCDW) management is thus far limited. Hence, to bridge this research gap and provide an improved understanding, the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guideline was adopted to systematically explore related literature towards the development of a web of barriers, integrated framework, and implementation strategies for CE adoption in BCDW management. The barriers to CE adoption in BCDW management were gleaned from 23-countries and consolidated as institutional and regulatory barriers, technological and information barriers, and organizational barriers, among others. A blended conceptual framework indicating the causality and interrelationship among the groups of barriers was determined using the interpretive structural modeling (ISM) approach. Ultimately, integrated implementation strategies were put forward to combat the identified barriers. Theoretically, this study has created a distinct character of the barriers to and strategies for the comprehensive promotion, implementation, and diffusion of CE in BCDW management. It has made a useful contribution to the existing literature through the mapping of a comprehensive co-existence and relationship among the barriers. This study has triggered a variety of empirically based research studies on the barriers, and success factors to promote CE in BCDW from a developed and developing economies' perspective in the future.
