CARBON CURED


CONCRETE


How do you

recycle CO 2 to make

stronger concrete?

Concrete is the most used man-made material on earth.^1


But before it can be used, it must fi rst be cured.


We’ve developed a new curing method, storing up to


200kg of CO 2 in every ton of cement. Making it as


strong as regular concrete in 3 days instead of 28,


for faster, more effi cient construction.


If the whole precast concrete industry switched to our


technology, we could recycle up to 246 million tons


of CO 2 a year2,3 – equivalent to removing emissions from


53 million cars.^4
