In a joint venture, Heidelberg Materials and CBI Ghana Ltd, a leading Ghanaian cement manufacturer located in Tema, Ghana, have completed the construction of the largest industrial-scale flash calciner for clay worldwide.
The installation has a capacity of more than 400 000 tpy of calcined clay. First batches of calcined clay cement with reduced clinker content have already been delivered to customers.
Calcined clay is a particularly well-suited raw material for West African countries without large limestone deposits, enabling them to reduce their dependence on clinker imports.
Replacing traditional cement clinker with supplementary cementitious materials (SCM) is a crucial pillar of Heidelberg Materials’ decarbonisation strategy.
As an emerging economy with a fast-growing population, cement consumption in Ghana is expected to double over the next 15 years, offering a large market potential and significant opportunities for a transition to sustainable solutions from local production.
