Ghana has inaugurated the world’s largest calcined clay cement plant, marking a significant step in the country’s push for industrial growth and greener manufacturing.

President John Dramani Mahama commissioned the $110 million facility at the Tema Free Zones Enclave, developed by CBI Ghana Ltd.

The plant has an annual production capacity of 1.5 million tonnes of environmentally friendly cement and uses limestone calcined clay technology to cut carbon emissions while maintaining the strength needed for modern construction.

Mahama described the project as more than the opening of a factory, saying it represents a key step in repositioning Ghana as a leading industrial hub in Africa and supporting the country’s broader economic transformation plan.

The development comes as the global cement industry seeks cleaner alternatives to traditional production, which relies heavily on clinker and is responsible for significant carbon emissions.

Limestone calcined clay cement technology is increasingly promoted worldwide as a low-carbon solution that replaces part of the clinker with calcined clay and limestone while maintaining construction strength.

The President reaffirmed the government’s target to raise manufacturing’s contribution to GDP to at least 15 percent by 2030 as part of efforts to expand industry, strengthen local production, and create sustainable jobs.

He also commended the Ghana Free Zones Authority and the Ministry of Trade, Agribusiness and Industry for facilitating the investment, while praising CBI Ghana for advancing a project that supports the global transition toward low-carbon construction materials.

Operating under the government’s 24-Hour Economy policy, the new plant is expected to generate employment, reduce Ghana’s reliance on imported clinker, and boost the country’s capacity to produce competitively for domestic markets and export under the African Continental Free Trade Area, according to Ghana Presidency.
