Overcoming barriers to the adoption of innovative sustainable construction materials in a developing economy

Purpose This study proposes measures to overcome barriers hindering the adoption of innovative sustainable construction materials (ISCMs) in Nigeria, to strengthen local sustainable practices and support global goals, particularly SDG 9 (industry, innovation and infrastructure) and SDG 12 (responsible consumption and production). Design/methodology/approach A quantitative cross-sectional survey was conducted with 113 construction professionals in Lagos. Data were analysed using exploratory factor analysis (principal component analysis with varimax rotation) to identify barrier components, while analysis of variance and post hoc Tukey tests assessed differences across micro, small and medium-sized enterprises (MSMEs). Findings Three barrier components were identified: institutional and knowledge-based, capacity and regulatory and economic and resource. Lack of government support, limited training and poor awareness of ISCM benefits were most critical, particularly among small and medium-sized enterprises. Economic barriers were less influential yet evident. Perceptions differed significantly across organisational categories, indicating that MSMEs experience and prioritise barriers differently. Practical implications The results provide practical guidance for policymakers, industry associations, firms and suppliers. Revising building codes, strengthening enforcement, expanding capacity-building, fostering collaboration and promoting long-term value perspectives are essential to accelerate ISCM adoption in Nigeria. Originality/value This study moves beyond cost-centred perspectives by demonstrating the pivotal role of regulatory, cultural and technical barriers in emerging markets. It offers a contextualised understanding of ISCM adoption in Nigeria, with insights applicable to similar developing economies, thereby advancing a more resilient and sustainable construction industry.
