A greener way to make concrete buildings originated by Kristian Hertz, a civil engineering professor at the Technical University of Denmark, combines "ordinary concrete and lightweight concrete, drawing inspiration from the human body." Hertz's approach could help reduce by up to half the amount of concrete used to build. Hertz has teamed up with Abeo A/S, which has numerous patents for key technologies, to further develop the technology, which Abeo claims will also cut energy use and carbon dioxide emissions.
