Optimization and Integration of Circular Economy Principles in Housing Construction Project in Lagos, Nigeria

Abstract

The increasing demand for housing and the environmental impacts of construction activities have highlighted the importance of adopting sustainable practices. Circular economy principles, emphasizing resource efficiency, waste minimization, and lifecycle design, provide a promising alternative to the linear economic model in the construction industry. The study focused on evaluating and optimizing the application of circular economy principles in housing construction in Lagos, Nigeria, using Dutum Company Ltd. as a case study. The objective was to assess the current practices of Dutum Company Ltd., identify challenges and opportunities for circular economy integration, and propose a practical framework for optimizing these principles. Data were gathered from company reports, website content, and interviews with key personnel. The collected information was synthesized and analyzed to evaluate Dutum’s alignment with circular economy principles and its potential for improvement. The findings indicated that Dutum had partially integrated circular economy practices, particularly in lifecycle design and resource efficiency. Modular construction methods and material reuse initiatives were identified as strengths, while gaps were noted in waste minimization, recycling infrastructure, and renewable energy adoption. Financial constraints, regulatory challenges, and cultural resistance were significant barriers. A structured framework was proposed to guide Dutum in optimizing circular economy practices. The framework included sustainability audits, capacity-building initiatives, adoption of advanced technologies such as Building Information Modeling (BIM), and phased implementation of renewable energy systems. Recommendations prioritized collaboration with stakeholders, training programs for employees, and the development of internal policies to institutionalize circular economy practices. The study highlighted the potential for circular economy principles to transform housing construction in Lagos, improving environmental sustainability and resource efficiency while offering long-term economic benefits. The findings contribute to the understanding of sustainable construction practices and provide a practical roadmap for implementing circular economy principles in similar contexts.
