Cement & lime

Calix's technology has the potential to enable both the cement and lime industries reduce their carbon dioxide (CO2) emissions dramatically.

Cement is the second most consumed substance on Earth after water, fulfilling an essential role in providing society’s need for housing and infrastructure while lime is used in a variety of applications including in the iron & steel, chemical, paper and pharmaceutical industries. Both sectors have relatively high carbon dioxide (CO2) emissions.

The cement and lime industries have relatively high carbon dioxide (CO2) emissions and are responsible for around 8% of global CO2 emissions.

The majority of CO2 emissions are released directly and unavoidably from the processing of the raw materials – not from the combustion of fossil fuels.

In order to reach the EU’s emissions reductions targets by 2030, and global carbon neutrality ambitions by 2050, carbon capture technologies that stop CO2 reaching the atmosphere will need to be applied to the majority of European cement plants, and LEILAC is uniquely placed to support Europe to achieve these targets in a timely, effective and efficient manner.

Our Technology allows for the direct separation of CO2

Calix’s technology re-engineers the existing process flows of a traditional calciner, indirectly heating the limestone via a special steel vessel. This unique system enables pure COto be captured as it is released from the limestone, as the furnace exhaust gases are kept separate.

The solution requires no additional chemicals or processes, and minimal changes to the conventional processes for cement.

Applying and scaling up the technology to the cement industry carries a large number of risks. To quickly and effectively apply this technology, the European-Australian collaboration LEILAC projects include consortia of some of the world’s largest cement, and lime companies, as well as leading research and environmental institutions.

Project LEILAC

Calix is leading a consortium of some of the world’s largest cement and lime companies with the goal of developing a breakthrough carbon capture process that would enable both cement and lime industries to reduce their carbon dioxide (CO2) emissions dramatically.
