President John Dramani Mahama has commissioned the world’s largest calcined clay cement plant at the Tema Free Zones Enclave, describing the landmark facility as a major step forward in Ghana’s industrial revival and sustainable manufacturing drive.
The $110 million plant, developed by CBI Ghana Ltd, has an annual production capacity of 1.5 million tonnes of environmentally friendly cement and introduces limestone calcined clay technology that significantly reduces carbon emissions while maintaining the strength required for modern construction.

President Mahama noted that the commissioning represents more than the opening of a factory; it is a tangible step toward repositioning Ghana as a leading industrial hub in Africa.
The President also announced government’s ambitious target to increase manufacturing’s contribution to GDP to at least 15 percent by 2030, a key pillar of the administration’s 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 their roles in facilitating the investment, while congratulating the management of CBI Ghana for advancing a project that strengthens Ghana’s position in the global transition toward low-carbon construction materials.
The facility, designed to operate continuously under the government’s 24-Hour Economy policy, is expected to create jobs across the 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.
