Reducing CO2 emissions

The cement and other minerals sector in the Czech Republic accounts for about five percent of total CO₂-equivalent greenhouse gas emissions. Cement production generates basic process_CO2 emissions from the decomposition of limestone and fuel CO₂ emissions from the combustion of fuels in the rotary kiln system during clinker firing. 

Our cement plant has succeeded in reducing fossil CO₂ emissions by about 40% in 2023 compared to 1990 due to many technological and process changes in cement production.

In general, there are several options for reducing CO₂ emissions. These include:

• the use of alternative fuels
• improving the thermal efficiency of the rotary kiln system
• optimization of the raw material mix by using decarbonized raw materials in the preparation for clinker firing in terms of appropriate chemical composition
• application of blended cements and development of alternative cements with lower clinker content,
• the use of renewable electricity and the challenge for the future is the use of low-emission hydrogen (own photovoltaic power plant with an installed capacity of 858.36 kW - the sun thus helps in the production of clinker)
• CO₂ capture, storage and processing, i.e. the abbreviation used for CCS/CCU technology and our company is involved in the preparation and development of future CCS/CCU strategies and potential opportunities within the Czech Republic and the EU.
