As the world’s largest flash calciner to enter operation CBI Ghana is spearheading the shift to calcined clay-based cement in Africa. The project responds to both economic and environmental imperatives, addressing high clinker import costs and the need for sustainable building materials. The company intends to use the clay in LC3 formulations, a type of cement blend that typically contains 50-60% clinker, 20-30% activated clay and 15-20% limestone. To enable this project, the company had to break through regulatory and market challenges, particularly the absence of a dedicated LC3 standard in Ghana.
Ghana imports clinker, adding 25% logistical costs and macro-economic risk. LC3 can be produced using local materials, is cheaper, and can reduce clinker rates to 35% (we are currently close to 40%). Despite industry inertia, we aim for LC3-35 to become the African standard and have already inspired several African nations.

CBI hana’s flash calciner is an industrial furnace that rapidly heats, dehydrates (or ‘calcines’) and cools locally-sourced clay in a matter of seconds to create a pure and highly reactive activated clay. Activated clay is a highly promising Supplementary Cementitious Material (SCM) as it is widely available and provides strong concrete performance.

Mission Possible Partnership | MPP
Mission Possible Partnership (MPP) is an independent non-profit organisation advancing global clean industry transformation. Since 2019, we have been working with some of the most energy-intensive industries: aluminium, aviation, cement, chemicals, shipping and steel, to cut their nearly 25% of global GHG emissions.
We mobilise business, finance, government and civil society leaders to speed up the shift to clean materials, chemicals and fuels. Having charted sectoral pathways to net-zero, we continue to forge new territory, lifting the barriers to enable a critical mass of clean industrial projects to break ground by 2030.
Mission Possible Partnership has people and partners on the ground in North America, Brazil, Europe, the Middle East, North Africa, India and Asia Pacific.
Industrial Transition Accelerator | ITA
The ITA is a global multi-stakeholder platform -managed by Mission Possible Partnership – to fast-track decarbonisation across heavy-emitting industry and transport sectors. It aims to significantly grow the pipeline of commercial-scale, clean industrial projects to reduce emissions by 2030.
Build Clean Now | BCN
Build Clean Now is a global campaign bringing together governments, companies and finance to accelerate the pace at which clean industrial projects are financed and built, year-on-year. It is led by the Industrial Transition Accelerator (ITA) and Mission Possible Partnership (MPP).
Norsk e-Fuel is building one of Europe’s first large-scale power-to-liquid plants, designed to produce around 80,000 tonnes of e-fuels (of which about 80% will be SAF) each year at the Port of Rauma in Finland.
