Scientists develop 3D concrete printing method that captures carbon dioxide

Scientists at the University of Michigan have developed an innovative 3D concrete printing method that not only constructs buildings but also captures carbon dioxide (CO2) from the atmosphere. This method involves using a special concrete mix that includes magnesium oxide, which reacts with CO2 to form stable carbonates, effectively sequestering the greenhouse gas. The process, known as carbonation curing, allows the concrete to absorb CO2 during the printing and curing stages. This dual-purpose approach not only reduces the carbon footprint of construction but also potentially turns buildings into carbon sinks. The research, published in the journal "Nature Communications," highlights the potential for this technology to revolutionize the construction industry by making it more environmentally friendly, addressing both the emissions from cement production and the operational emissions of buildings.
