Enhancing carbon storage capacity in concrete 

Because building materials account for the largest share of global material flows, Empa researchers are focusing on leveraging the potential to store solid carbon in concrete and asphalt. By using large amounts of carbon-rich, high-strength aggregates and fillers, the goal is to turn our infrastructure into a durable carbon sink while boosting climate-friendly construction.
