Towards achieving circular economy in the Nigerian construction industry: policymakers perspectives and conceptual framework development

Abstract

Purpose The construction industry faces significant challenges in managing waste and resource inefficiency, contributing to environmental degradation and unsustainable practices. Despite the potential of circular economy (CE) practices to address these issues, there is limited understanding and inadequate policy support for their effective implementation. This study investigates the perspectives of policymakers on achieving CE in the Nigerian construction industry. Specifically, this study examines policymakers’ understanding of CE, key influencing policies, the challenges encountered in implementing CE practices and how policies can support the transition to CE. Design/methodology/approach This study adopts a qualitative approach to explore the perspectives of policymakers towards achieving CE in the Nigerian construction industry. About 50 participants were purposively selected to participate in this study to provide comprehensive data for the study. Saturation was attained on the 34th participants. The data were analysed using thematic analysis to identify key themes and insights. Findings This study identified significant gaps and challenges hindering policymakers' effective implementation of CE practices. The challenges include financial constraints, resistance to change, inadequate regulatory frameworks, lack of infrastructure, skill gaps and weak enforcement mechanisms. Recommendations for improvement include financial incentives, updated building codes, enhanced enforcement, mandatory education and training programmes and increased collaboration between government, industry and academia. A conceptual framework was developed to promote the implementation of CE in the construction industry. Originality/value This study is the first to examine the perspectives of policymakers on CE in the Nigerian construction industry, offering unique insights and practical recommendations. The conceptual framework adds a structured approach to implementing CE practices, contributing to the limited research on CE in developing countries and providing a robust foundation for future studies to expand the scope and employ quantitative methods to measure the impact of CE practices.
