Continental Blue Investments Ghana Limited (CBI) is a producer of cement in Ghana and operates a 550,000 tons p.a. facility outside Accra in southern Ghana and plans to almost triple the production to 1.4 million tons annually. The cement is sold for commercial, industrial and residential construction projects, as well as complex infrastructure.
The world’s largest calciner system
As the production of cement is one of the heaviest global emitters of carbon, CBI is constructing a 405,000 tons per annum clay calcination unit, which is the world’s largest calciner system to date
This will enable CBI to use locally sourced calcined clay to be used partly instead of imported clinker, which is a major contributor to the high emissions from the production process. The substitution will lead to a reduction of carbon emissions by up to 20 per cent per ton cement produced without compromising the quality of the product. Including the sale of calcined clay to other cement producers in Ghana, the total avoided emission is expected to be close to 30 per cent compared to current production technology.
The introduction of calcined clay in the production of cement supports the green transition and is in line with the EU green taxonomy, that sets an upper limit for CO2 emissions intensity.
