In Nigeria, the construction industry faces a growing environmental crisis due to the mismanagement of construction and demolition (C&D) waste. A recent study led by H. C. O. Unegbu from the Department of Mechanical Engineering at Ahmadu Bello University sheds light on this pressing issue, revealing the complexities and challenges that hinder sustainable practices in waste management.
The research, published in ‘Discover Civil Engineering’, provides a comprehensive analysis of C&D waste management practices across Nigeria, drawing on data from 150 stakeholders, including contractors, engineers, and policymakers. The findings highlight a concerning trend: a heavy reliance on landfills, largely attributed to the high costs associated with recycling and a lack of adequate facilities. “The economic disincentives for sustainable practices create a cycle that is hard to break,” Unegbu notes, emphasizing the urgent need for change.
The study uncovers a critical gap between awareness of existing regulations and their enforcement. While many stakeholders recognize the importance of sustainable waste management, the lack of robust regulatory frameworks has led to inconsistent practices. “Without stronger regulations and consistent enforcement, we will continue to see C&D waste contributing to environmental degradation,” Unegbu warns.
Moreover, the research identifies socio-economic factors and education levels as significant influences on waste management practices. This insight suggests that improving education and awareness can play a crucial role in shifting industry norms toward sustainability. The study advocates for an integrated approach that combines enhanced regulatory measures, infrastructure development, and continuous training programs for industry professionals.
Commercially, the implications of this research are profound. As global attention increasingly focuses on sustainability, construction companies in Nigeria that adopt more responsible waste management practices can not only comply with future regulations but also enhance their marketability. “Investing in sustainable practices today could lead to significant cost savings and improved public perception tomorrow,” Unegbu asserts.
The findings of this study are not just relevant for Nigeria; they resonate with the broader global movement towards sustainable construction practices. As the industry evolves, the need for comprehensive strategies that address the unique challenges faced by developing countries becomes ever more critical.
