Summary:
- Researchers at Northwestern University have developed a new type of concrete that is carbon-negative, meaning it actively removes more carbon dioxide from the atmosphere than it emits during production.
- The concrete is made by incorporating calcium oxide derived from waste materials, which reacts with CO2 to form calcium carbonate, effectively trapping the greenhouse gas.
- This innovative concrete could have significant implications for the construction industry, which is responsible for a significant portion of global carbon emissions, potentially helping to mitigate the environmental impact of building and infrastructure development.
