How LC³ Can Reduce CO₂ Emissions in Cement Production by Up to 40%

The 27th United Nations Climate Change Conference (COP 27) has begun in Egypt. Progress since COP 26 has been minimal, commitments have not been fulfilled, and climate change continues to advance. There are few effective measures that can be implemented quickly. LC³ technology, which helps reduce CO₂ emissions from cement production, is one of the most promising solutions.

LC³ is a new type of cement based on a blend of limestone and calcined clay. It can reduce CO₂ emissions by up to 40%. It is manufactured using limestone and low-grade clays, both of which are abundantly available. It is cost-effective and does not require major capital modifications to existing cement plants.

At EcoSur, we are committed to making LC³ a widely adopted, mainstream cement in the global cement market. For more than 30 years, we have conducted research and testing to reduce the environmental impact associated with cement production. We are now at the commercial production stage and are helping more cement manufacturers transition to this technology.

With funding from the Swiss Agency for Development and Cooperation, through its Global Climate Change Programme, we have been able to take LC³ technology from laboratories in Cuba, Switzerland, and India to the rest of the world. Over the past three years, our outreach to cement producers has grown exponentially.

Currently, approximately 40 companies in 25 countries are interested in LC³, and commercial production has been established in two countries. In 2021, this technology had already helped save approximately 220,000 tonnes of CO₂, with further reductions expected in 2022.
