TECH WATCH
In Cairo, where rising construction costs and a booming building sector create challenges, engineers have developed innovative bricks made entirely from desert sand, using natural enzymes and plant-based polymers as a binding formula.
This advanced process cures at room temperature, eliminating the need for cement, water, and kilns, and produces zero CO₂ emissions—contrasting sharply with traditional concrete, which accounts for 8% of global emissions.
The result is a solid block that lab tests claim is stronger than concrete, withstanding extreme temperatures, erosion, and high compressive force, while being 40% lighter, easing transport and suiting low-cost housing in arid regions.
The startup behind this has begun constructing schools and homes in Egypt’s rural villages, drawing interest from governments in North Africa and the Middle East, where sand is abundant but concrete is costly.
