Balancing planet & profit: How CBI Ghana’s sustainable cement production is redefining the industry

In the industrial hub of Tema, a quiet transformation is reshaping one of the world’s most carbon-intensive industries. At the center of it is CBI Ghana Ltd., whose breakthrough product—Supacem LC3-45—is not just another cement innovation, but a bold reimagining of how construction can align with sustainability. This is not incremental change. It is a shift in paradigm.

A new kind of cement for a new era

Supacem LC3-45 is built on Limestone Calcined Clay Cement (LC3) technology—an advanced formulation that leverages Ghana’s abundant natural resources, particularly limestone and clay. The result is a high-performance cement that significantly reduces environmental impact without compromising strength or durability. “This is cement designed not just to build structures, but to protect the future.”

By cutting CO₂ emissions by up to 40% compared to traditional cement, Supacem LC3-45 challenges long-held assumptions about the trade-off between industrial growth and environmental responsibility.

Innovation at industrial scale

At the heart of this transformation lies a technological marvel: the world’s largest flash calciner, capable of producing 1,200 tonnes of calcined clay daily. This state-of-the-art facility enables large-scale production of LC3 cement—making sustainability not just possible, but scalable. “Sustainability must move from niche to norm—and scale is what makes that possible.”

Beyond environmental gains, the innovation delivers exceptional performance. Supacem LC3-45 offers superior compressive strength and enhanced durability, making it particularly suited for Ghana’s demanding coastal environments.

Key Highlights

Lower carbon footprint
Supacem LC3-45 achieves under 400 kg CO₂ per tonne, significantly outperforming the traditional benchmark of 654 kg.

Pioneering technology
The world’s largest flash calciner drives high-volume, high-quality LC3 production.

Built for performance
Enhanced durability and strength tailored for Ghana’s infrastructure needs.

Economic value creation
307 direct jobs created and a substantial reduction in Ghana’s $500 million annual clinker imports.

Driving economic and industrial transformation

CBI Ghana’s innovation extends far beyond product development—it is reshaping the economics of the cement industry.

By reducing reliance on imported clinker, the company is helping Ghana retain value within its own economy. The ripple effect is significant: job creation, strengthened local supply chains, and increased industrial self-sufficiency.

At the same time, CBI Ghana’s commitment to local sourcing and production is positioning it as a key player in Ghana’s industrialisation agenda.

Collaboration powering progress

CBI Ghana’s success is anchored in strategic partnerships that bridge global expertise and local innovation. Collaborations with Heidelberg Materials, Kwame Nkrumah University of Science and Technology, EPFL, and the Ghana Standards Authority have been instrumental in advancing LC3 adoption.

Together, these institutions have supported the development and implementation of GS PAS 5:2024, placing Ghana at the forefront of global sustainable cement standards.

A broader impact: economy, environment, community

CBI Ghana’s approach reflects a deeper philosophy—one where business success and societal impact are intertwined.

Economic Impact

• Creation of 307 direct jobs
• Reduced dependence on imported clinker
• Strengthened local industrial value chains

Environmental Leadership

• Significant CO₂ emissions reduction
• Promotion of sustainable construction practices
• Adoption of globally recognised LC3 standards

Community & Skills Development

• Partnerships with academic institutions for research and training
• Capacity-building initiatives for local talent
• Support for Ghanaian suppliers through local procurement

“Sustainability is not just about reducing emissions—it’s about creating systems that benefit people, industry, and the environment alike.”

Leading the Future of Construction

As Ghana’s construction sector continues to expand, the demand for materials that balance performance with sustainability has never been greater. For Frédéric Albrecht, CEO of CBI Ghana, the vision is clear:

“CBI Ghana is committed to driving innovation in the cement industry, leading the way towards a greener future for construction in Ghana and beyond.”

Supacem LC3-45 is more than a product—it is proof that the future of construction can be both resilient and responsible.

And in Tema, that future is already taking shape.
