Decarbonization

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 and Dyckerhoff, are committed to further reducing CO₂ emissions throughout our entire cement and concrete value chain, and have stated that in our roadmap "Our Journey to Net Zero“.

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.

We base the measures to reduce our CO₂ emissions on 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 2045 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 offers among others these CO₂ reduced cements:

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⁾

View Flyer (German language)

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
- Screeds
- Plaster and masonry mortar
- Concrete according to DIN EN 206 / DIN 1045

Delivery
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.
