Mahama Commissions World’s Largest Calcined Clay Cement Plant in Tema

President John Dramani Mahama has commissioned the world’s largest calcined clay cement plant at the Tema Free Zones Enclave, describing the facility as a major milestone in Ghana’s industrial revival and sustainable manufacturing agenda.

The $110 million plant, developed by CBI Ghana Ltd, has an annual production capacity of 1.5 million tonnes of environmentally friendly cement. The facility introduces limestone calcined clay technology (LC3), an innovation that significantly reduces carbon emissions while maintaining the strength required for modern construction.

Speaking at the commissioning ceremony, President Mahama said the project represents more than the opening of a factory, emphasizing that it is a concrete step toward repositioning Ghana as a leading industrial hub in Africa.

According to him, the investment reflects the country’s growing commitment to sustainable industrialisation and value-added manufacturing.

The President also announced government’s ambitious plan to increase manufacturing’s contribution to Gross Domestic Product (GDP) to at least 15 percent by 2030. The target forms part of the administration’s broader economic transformation agenda aimed at expanding industry, strengthening local production, and creating sustainable employment opportunities.

President Mahama commended the leadership of the Ghana Free Zones Authority and the Ministry of Trade, Agribusiness and Industry for facilitating the investment.

He also congratulated the management of CBI Ghana for advancing a project that strengthens the country’s position in the global transition toward low-carbon construction materials.

The facility is designed to operate continuously under the government’s 24-Hour Economy policy, a strategy intended to boost productivity and industrial output.

Officials say the plant is expected to create jobs across the cement value chain, reduce Ghana’s dependence on imported clinker, and support the country’s ambition to produce competitively for both domestic consumption and export under the African Continental Free Trade Area.

Industry analysts believe the project could play a key role in lowering the environmental footprint of cement production while strengthening Ghana’s manufacturing sector and export potential.
