CEMEX to participate in LEILAC 2 project

CEMEX has announced its participation in the Low Emissions Intensity Lime and Cement 2 (LEILAC 2) project, a research and innovation initiative aimed to decarbonise the cement production process.

The LEILAC 2 project is funded by the European Union's Horizon 2020 research and innovation programme. The project team comprises leading industrial, technology, and research & development partners.

CEMEX had a very active participation in LEILAC 1, working with the partners to develop the novel direct separation of process carbon emissions derived from the clinker/cement manufacture. The highly concentrated CO2 resulting from the technology can then be easily handled via capture and/or storage. Process emissions are roughly 60% of the direct CO2 emissions from cement production. Thus, this technology can contribute significantly to the decarbonisation of the whole sector.

CEMEX is enthusiastic and determined to continue its contributions to the project by bringing expertise, experience, and key resources. For example, simulation experts undertook significant modelling of the CO2 reactor tube to obtain the required capture rate. CEMEX's technical team also tested novel designs for the CO2 reactor tube, given its deep understanding of the cement production process and how the technology can be implemented most effectively.

CEMEX decided to participate in LEILAC 2 pursuing and contributing to the technology's development utilising its gasification process's expertise. It is also leveraging its skills in alternative fuel consumption and computational fluid dynamic simulation design, aiming to succeed in the second stage of the LEILAC project.

"Our participation in the LEILAC 2 project is another example of our continued efforts to deliver net-zero CO2 concrete products globally by 2050," said Davide Zampini, Head of Global R&D. "We are determined to have a significant direct involvement in research and development efforts pursuing high impact technologies in carbon capture, use, and storage."

CEMEX announced in 2020 its Climate Action strategy, defining a global target of a 35% reduction of CO2 emissions per ton of cementitious products by 2030. For its operations in Europe, CEMEX also defined a 55% reduction target, in line with what the European Commission set as a new goal for all its member states. To complement this strategy with a longer-term vision, CEMEX also established an ambition to deliver net-zero CO2 concrete to all its customers globally by 2050.
