Converting Plastic Waste into Building Materials May Ease Housing Shortage, Expert Says

Dr Foluke Jegede

A housing researcher has identified plastic waste as a potential resource for addressing Nigeria’s housing deficit, arguing that recycled plastics can be transformed into affordable building materials capable of reducing construction costs while tackling environmental pollution. The proposal comes amid growing concerns over the country's housing shortage and the increasing volume of plastic waste generated across urban centres. According to researchers and waste management experts, innovative recycling technologies could simultaneously support housing delivery and environmental sustainability.

The initiative forms part of ongoing research efforts aimed at exploring alternative construction materials that can make housing more affordable while advancing circular economy principles. The concept aligns with broader discussions around sustainable urban development and resource-efficient construction practices.

Research Focuses on Converting Waste into Building Materials

Foluke Jegede, a housing researcher and head of the Centre for Housing and Environmental Studies at Covenant University, Ota, said her team is implementing a project known as "Plastic to Purpose." The initiative seeks to convert plastic waste into construction materials that can be used for housing and other building applications. According to her, the project aims to reduce environmental pollution while creating more affordable alternatives to conventional building materials.

The research is supported through a grant from the David Oyedepo Foundation and involves collaboration with industry stakeholders, including Richbol Nigeria and the Nigerian Building and Road Research Institute. These partnerships are expected to support technical development and facilitate future commercial applications of the technology.

Researchers argue that converting waste into construction products offers multiple benefits, including cleaner communities, lower housing costs and improved resource efficiency. The initiative also seeks to create economic opportunities within the recycling value chain by increasing demand for collected plastic waste.

Housing Deficit Creates Demand for Alternative Solutions

Nigeria continues to face a significant housing deficit, with rapid urbanisation, population growth and rising construction costs placing additional pressure on housing supply.

Industry stakeholders have repeatedly identified the high cost of building materials as one of the major factors limiting affordable housing delivery. Cement, steel, imported finishing materials and infrastructure costs continue to increase development expenses, making homeownership difficult for many households.

Against this backdrop, researchers believe alternative materials derived from recycled waste could contribute to reducing construction costs while expanding access to affordable housing. The approach reflects a growing global trend towards sustainable building technologies designed to improve affordability and environmental performance.

Plastic Waste Presents Environmental and Economic Opportunity

Nigeria generates substantial volumes of plastic waste annually, much of which ends up in landfills, waterways and drainage systems. Environmental experts warn that plastic pollution contributes to flooding, environmental degradation and public health challenges, particularly in densely populated urban areas.

Waste management professionals argue that treating plastic waste as an economic resource rather than a disposal problem could unlock significant opportunities for housing, manufacturing and job creation.

The Association of Waste Managers of Nigeria (AWAMN) recently advocated greater adoption of recycled plastics in construction, noting that plastic waste can be processed into durable building materials through modern recycling technologies. According to the association, thermoplastic construction systems can combine recycled plastic with sand and other materials to create strong and sustainable building components.

Experts maintain that widespread adoption of such technologies could help reduce environmental pollution while supporting housing delivery objectives.

Industry Collaboration Seen as Key to Commercialisation

Researchers acknowledge that large-scale adoption will require collaboration between academia, government agencies, developers and recycling companies.

According to Jegede, one of the challenges facing the initiative is public perception. Many potential users remain unfamiliar with alternative building materials and may question their durability, safety or aesthetic appeal. To address these concerns, the research team plans to develop prototype structures showcasing the practical application of recycled plastic materials in construction.

Industry experts believe demonstration projects could play an important role in building confidence among developers, investors and homebuyers.

They also emphasise the need for regulatory support, updated building standards and investment in recycling infrastructure to enable broader adoption of sustainable construction materials.

Circular Economy Principles Gain Momentum

The proposal aligns with Nigeria's growing focus on circular economy strategies that seek to maximise resource efficiency and minimise waste.

Environmental stakeholders increasingly advocate policies that encourage recycling, material recovery and sustainable production systems. Several recent initiatives have focused on strengthening recycling infrastructure and supporting private-sector investment in waste processing facilities.

Advocates argue that integrating recycled materials into housing and infrastructure projects could create new markets for waste products while supporting environmental objectives and economic growth.

For the housing sector, circular economy approaches may provide opportunities to reduce dependence on conventional materials and improve affordability without compromising quality.

Implications for Nigeria’s Housing Market

For developers and policymakers, the use of recycled plastic materials presents an opportunity to explore innovative solutions to longstanding housing challenges.

Affordable housing remains a priority across Nigeria's rapidly expanding urban centres, where housing demand continues to outpace supply. Alternative construction materials could contribute to lowering development costs and improving housing accessibility if proven commercially viable.

At the same time, integrating recycled products into construction could support broader sustainability goals by reducing landfill waste and encouraging responsible resource management.

While significant work remains before widespread adoption becomes possible, the research highlights the growing intersection between environmental sustainability and housing development.

Outlook

The proposal to convert plastic waste into building materials underscores the potential of innovation to address two of Nigeria's pressing challenges: housing shortages and environmental pollution. Researchers and industry stakeholders argue that sustainable construction technologies could help reduce building costs, create economic opportunities and improve housing delivery outcomes.

As urban populations continue to expand and demand for affordable housing grows, alternative building materials may become an increasingly important component of Nigeria's long-term housing strategy. Success, however, will depend on continued research, industry collaboration, supportive regulations and public acceptance of new construction technologies.
