Credit Gabriel Falzone/UCLA Cement production makes up eight percent of man-made carbon emissions. But a new technology developed by the University of California, Los Angeles might change that. Iman Mehdipour, UCLA project scientist in the Department of Civil and Environmental Engineering at the Samueli School of Engineering, was part of a team that developed CO2Concrete. That technology uses flue gas from power plants to make cement, which is the biggest component in concrete. "We utilize the carbon dioxide permanently and directly. We converted the carbon dioxide into some solid minerals. We inject it into the construction materials," he said. "We were able to reduce the cement."
