Carbonfold, founded by Hannah Brooks, makes a concrete additive that permanently binds captured carbon dioxide while making the concrete stronger.
Captured CO2 is mineralized into a powder that replaces part of the cement in a standard mix. Each cubic meter stores carbon and needs less cement, which is where most of concrete's emissions come from.
Hannah wants every new building to be a place carbon goes to stay. PhD in materials science; postdoc on mineralization chemistry.
