Concrete contributes seven per cent of global carbon emissions and numerous efforts are underway globally to decarbonise this foundation industry.

The Cement 2 Zero project is one such effort that is developing, scaling and delivering a low carbon, circular cement technology that takes demolished concrete and recovers recycled cement paste from it.

 

 

This cement paste is then introduced in place of lime to recycled steel in an electric arc furnace (EAF) where it bubbles through the molten steel to purify it. As it does so, it creates a flux that rises to the top of the molten steel to form a protective layer (slag) that prevents the steel being exposed to air.
