This study evaluates the circular economy potential of machine-pressed earth blocks (MPEBs) for affordable housing in Lagos, Nigeria. Compared to conventional materials, MPEBs show 85% fewer carbon emissions, 45-55% cost reduction, and full recyclability. A six-pillar integration framework is proposed for adoption in low- to middle-income housing schemes.

日本のGX文脈において
ナイジェリアの事例だが、循環型建設への移行や低炭素建材に関する知見は日本の建設業界にも示唆を与える。特に、日本では建設廃材の削減や土着材料の活用が注目されており、本論文のフレームワークは参考になる。
In the global GX context
This paper contributes to the global discourse on circular construction and low-carbon materials, particularly relevant to developing countries seeking affordable housing solutions. The lifecycle assessment approach and proposed framework can inform similar initiatives worldwide, aligning with UN SDGs and climate goals.
👥 読者別の含意
🔬研究者:Researchers in sustainable construction and circular economy can adopt the lifecycle assessment methodology and framework for similar studies.
🏢実務担当者:Construction firms and housing developers can use the findings to evaluate earth blocks as a cost-effective, low-carbon alternative.
🏛政策担当者:Policymakers in housing and environment can consider regulatory reform and incentives to promote earth-based construction technologies.
📄 Abstract（原文）
The urbanization in Lagos has significantly increased the demand for affordable housing and aggravated environmental degradation, largely as a result of dependence on energy-intensive construction materials. he prevailing linear take, make, and dispose model in the construction industry is a major contributor to material waste and carbon emissions, indicating the pressing requirement for a transition to circular construction systems. This study uses a mixed-method approach, in-tegrating an organised literature review, comparative material analysis, and lifecycle assessment of machine-pressed earth blocks (MPEBs) relative to conventional building materials used in Lagos. The research shows that MPEBs have significant circular-economy potential, as evidenced by local material sourcing, low embodied energy (0.45–1.5 MJ/kg), full end-of-life recyclability, and notably diminished construction costs. Comparative analysis shows that MPEBs pro-duce up to 85% fewer carbon emissions than reinforced concrete and are 45–55% less expensive per unit than sandcrete blocks in the current Lagos market. The proposed CE-MPEB integration framework delineates six strategic pillars for adoption: material sourcing, production standardization, regulatory reform, community capacity building, lifecycle de-sign, and economic incentivization. The study shows that MPEBs represent a viable and scalable strategy for promoting circular construction in Lagos, mainly within low- to middle-income housing schemes. Policy support, technical stand-ardization, and public and community awareness initiatives are identified as essential enablers for expanding the adop-tion of earth-based construction technologies.
