in Ghana's cement industry. CBI Ghana Ltd. (Producer of Supacem Cement) has invested $100 million in LC3 technology, marking a key step for Ghana's cement industry in producing cement from local raw materials. LC3 is an innovative blended Portland cement with the addition of metakaolin (calcined kaolinite clay) and limestone. The main components of LC3 are clinker, calcined clay, limestone and gypsum. Calcined clays and limestones have been commonly used as supplementary cementitious materials (SCM). The main innovation of LC3 is to combine a large amount of available low-grade kaolinite clay with another 15% of limestone, which together have a synergistic effect and achieve similar performance as OPC-CEM I.
CBI Ghana Ltd.'s New plant in Tema, the world's largest LC3 plant, provides a localized solution to the clinker problem by utilizing Ghana's abundant raw material resources to replace imported clinker. This innovation has not only reduced dependence on imports, but also reduced production costs, while reducing carbon emissions and bringing about a green revolution in Ghana's cement industry. Kobby Adams, commercial director
of Supacem, mentioned in the interview that the adoption of the latest LC3 standard by the Ghana Standards Authority in 2024 is an important step towards this innovation. This achievement is the result of two years of collaboration between Ghanaian institutions such as Nkrumah University of Science and Technology, University of Ghana and BRRI Ghana, as well as international universities and laboratories.
Ghana's cement industry has been dependent on imported clinker, making it vulnerable to foreign supply problems and global market volatility. The new plant in CBI Ghana Ltd., by producing large quantities of cementitious materials, reduces the impact of the clinker shortage on Ghanaian retailers and builders, and improves the stability of cement supply.
The project has not only created more than 160 direct jobs, but also brought tangible economic benefits to the local community through local sourcing and infrastructure development in Tema and Togom. In addition, Supacem empowers local women through training programs, providing them with more employment opportunities and career development paths. The application
of LC3 technology has significantly reduced carbon dioxide emissions, reducing carbon emissions by 40% compared with traditional cement production. This not only supports Ghana's commitment to climate action, but also provides a more environmentally friendly and sustainable future for Ghana's cement industry.
CBI Ghana Ltd. 'S investment in a world-class cement laboratory is seen as key to developing Ghana's talent in advanced LC3 technology. This places Ghana at the forefront of sustainable cement production in Africa. Emmanuel Cherry, CEO of the
Ghana Construction Chamber of Commerce, recently called for exploring local alternatives to clinker. Supacem's investment, supported by the Ghana Standards Authority's adoption of the LC3 standard, responds to this call, demonstrating how Ghana's innovation and resources address key industry needs.
