The GWP100 of DUCON® is 618.64 kg CO2-eqv/m³ and is significantly influenced by the CEM I 52.5 R in the cement compound. Cement is also the largest energy consumer in terms of primary energy demand, which totals PEtotal of 3417.16 MJ/m³. The share of renewable energy demand PEren, at 439.14 MJ/m³, is only about 12% of the total energy demand. Key to a further improvement of the life cycle assessment will be the reduction or substitution of the cement compound or a CO2-free production of cement.

To this end, DUCON has been working on an ecologically optimized alternative to the existing DUCON®.
By adapting the mix design, which is largely characterized by the substitution of CEM I with blastfurnace cement (CEM III), both the greenhouse gas potential can be reduced by up to 52% and the total primary energy demand by up to 37% compared to DUCON®.
