President John Dramani Mahama has commissioned the world’s largest calcined clay cement plant at the Tema Free Zones Enclave, describing the $110 million facility as a landmark in Ghana’s industrial revival and sustainable manufacturing drive.

The plant, developed by CBI Ghana Ltd, has an annual production capacity of 1.5 million tonnes of environmentally friendly cement. It introduces limestone calcined clay technology, which cuts carbon emissions significantly while maintaining the strength required for modern construction.

President Mahama said the commissioning represents more than the opening of a factory, calling it “a tangible step toward repositioning Ghana as a leading industrial hub in Africa.” He further announced government’s ambitious target to raise manufacturing’s contribution to GDP to 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.

The President commended the Ghana Free Zones Authority and the Ministry of Trade, Agribusiness and Industry for facilitating the investment, while congratulating CBI Ghana for advancing a project that strengthens Ghana’s role in the global transition toward low-carbon construction materials.
Designed to operate continuously under the government’s 24-Hour Economy policy, the facility is expected to generate jobs across the value chain, reduce dependence on imported clinker, and boost Ghana’s competitiveness in both domestic and export markets under the African Continental Free Trade Area (AfCFTA).
The commissioning of the Tema plant marks a significant step in Ghana’s industrialization journey, positioning the country as a frontrunner in sustainable construction and green manufacturing across Africa.
