Expert urges shift from traditional construction to eco-friendly alternatives

By Deborah Oladejo, Osogbo –

A civil engineering expert, Dr. Murtadha Adekilekun, has called for a deliberate transition from traditional construction methods to more environmentally sustainable alternatives, warning that continued reliance on outdated practices could accelerate environmental degradation.

Dr. Adekilekun, a senior lecturer in the Department of Civil Engineering at Osun State University, made the call while delivering the 3rd Annual Distinguished Lecture in honour of Engineer Timothy Abiona. The event, themed “From Waste to Wall: Pioneering Eco-friendly Building Solutions,” was organised by the Nigerian Institution of Civil Engineers (NSE), Osun State chapter, and held in Osogbo.

He stated that the conventional construction sector, which depends heavily on non-renewable resources, contributes significantly to global pollution and climate change. “The construction industry is responsible for nearly 40 percent of global CO₂ emissions, much of it linked to material production and waste,” he said.

Highlighting the consequences of continued use of such methods, Adekilekun noted that the extraction of sand, gravel, limestone, and timber—key materials in traditional building—leads to rapid resource depletion and long-term harm to natural ecosystems.

He advocated for an urgent embrace of alternative building solutions that convert waste into useful construction materials, including bricks, blocks, panels, and even full structural components. According to him, this innovation reduces landfill pressure and lowers the carbon footprint of construction.

“This approach transforms materials once considered useless into durable and sustainable building components. It’s not only cost-effective but also a responsible way to reduce environmental impact,” he explained.

In his remarks, the Chairman of NSE Osun State chapter, Engr. Bashiru Abiola, described the lecture as timely and relevant. He stressed the need for engineering professionals to lead the push toward sustainable infrastructure, especially in the face of growing climate challenges and urban waste concerns.

The event concluded with a presentation of gifts to Engineer Timothy Abiona, whose birthday coincided with the lecture, marking a celebration of both professional excellence and environmental advocacy.
