Gnanli Landrou is a materials scientist and entrepreneur. He was born in Togo, and when he was a young boy he travelled with his uncle in West Africa watching him build earth houses. As a doctoral student at ETH Zurich, Gnanli worked with mentor Professor Guillaume Habert and together, they developed a process to turn clay-based excavation material into an alternative cement free concrete. Importantly this material can be poured as concrete using the ready-mix infrastructure of the concrete industry.
His ETH spin-off company Oxara, is now developing a cement-free concrete made from clay-based excavation material with his main goal to solve the lack of affordable housing in Africa. In 2019 Forbes magazine listed Gnanli as one of Europe’s 30 most influential entrepreneurs under the age of 30.
