Concrete4Change sequestration technology that turns CO2 into concrete

Concrete4Change (C4C) is developing additive materials for concrete that act as carbon carriers. Recycled wood and plastic waste are prepared to become an ‘adsorbent’ that may capture and release CO2. Then, using a process unit, the carrier is loaded with carbon dioxide – mainly utilising CO2 captured from the carbon heavy flue gas from cement production as feedstock. This loaded carrier is mixed into either wet or dry concrete wherein it slowly releases the CO2, allowing for permanent mineralisation. Not only does this mineralisation make the concrete stronger, less cement is required to do the same job. With this technology, C4C also promises 10 times more carbon sequestration than existing approaches for ready-mix concrete. Image Concrete4Change.
