Low-carbon concrete factory for Saudi Arabia
The joint-venture from Next Generation SCM and City Cement aims to reduce CO2 emissions by 99%.
The factory only uses a sixth of the fuel needed for traditional cement production and operates at much lower temperatures, decreasing costs and emissions, claims the partnership.
In the existing factory in Denmark, the production of calcined clay is reported to generate 8kg of CO2 a tonne, a 99% reduction compared to the IEA average of 600kg/t of CO2.
One cubic metre of concrete traditionally carries 210kg of CO2, which is said to be reduced by 58% in the calcined clay supplementary cementitious material.
Production is planed to begin in the third quarter of 2025, with a target of 350kt in the first year and 700kt in year two.
