Large quantities of CO2 are released in the production of cement and its preliminary product cement clinker. Approximately two thirds of this can be attributed to raw material-induced process emissions from limestone calcination, and roughly one third to the energy-related CO2 emissions from the fuels used.
We, Buzzi Unicem and Dyckerhoff, are committed to further reducing CO2 emissions throughout our entire cement and concrete value chain.
We are reducing energy-related CO2 emissions by optimizing the efficiency of our plants and increasingly using alternative fuels. To reduce raw material-induced process emissions, we are replacing part of the raw material mix with alternative raw materials containing calcium and already calcinated materials.
Buzzi Unicem has introduced the CGreen label, which in the future will identify our products with a higher content of alternative raw materials and, thus, a reduced carbon footprint.
What does CGreen mean?
The "C" in our CGreen label symbolizes the 5C approach of the European cement association CEMBUREAU – Clinker, Cement, Concrete, Construction und (Re)Carbonation – towards a climate-neutral industry. The German association Verein Deutscher Zementwerke VDZ also builds on this approach in its jointly developed CO2 roadmap for the German cement industry.
The 5C approach describes our industry's path to completely reducing CO2 emissions by 2050 along the value chain stages clinker, cement, concrete, and building, as well as the recarbonation of CO2 into concrete during and after the use of a building component. We are committed to achieving the necessary objectives and course of action.
Dyckerhoff now offers new products with the CGreen label:
Dyckerhoff ECO COMFORT – bagged cements
CEM II/C-M (S-LL) 42,5 N-NA 1)
CEM II/B-M (V-LL) 42,5 N (az) 2)
Dyckerhoff ECO COMFORT are cements with an optimized composition and a carbon footprint that is up to 39 % lower than that of CEM I cements. They offer good processing properties and high-yield performance.
Fields of application
- Plaster and masonry mortar
-Concrete according to DIN EN 206 / DIN 1045
1) Lengerich, Neuwied
2) Berlin, Deuna, Hamburg, Hanau
Dyckerhoff CEDUR – bulk cements
CEM II/C-M (S-LL) 42,5 N 1)
CEM II/C-M (S-LL) 42,5 N-NA 2)
Dyckerhoff CEDUR are cements with a carbon footprint that is up to 39 % lower than that of CEM I cements. The optimized composition enables the production of sedimentation-stable concretes and additionally contributes to the conservation of natural resources. Dyckerhoff CEDUR are cements with low effective alkali content and have lower heat generation.
