− 22% less specific net CO2 emissions compared to 1990
(from 20% in 2018)
− 24% share of alternative fuels
− 74.5% clinker-/cement factor
In addition, we move forward with our R&D projects
on process integrated CO2-capturing as well as
re-carbonisation of recycled concrete.

Our Vision 2050
Our goal is to realise carbon neutral concrete by 2050 at the
latest.
▪ Lowering CO2 content in our products
▪ Reduction of CO2 in clinker
▪ Recycling of concrete
▪ Capturing of CO2

2/3 of CO2 emissions are unavoidable and associated with the limestone
Quarrying oflimestone (CaCO3)
Calcination of limestoneCaCO3 → CaO + CO2

For carbon neutrality we need CCU/S
Post-Combustion
Approach:▪ Amine-based absorption of CO2.
▪ Capture from the flue gas.
Next steps:▪ Full-scale CCS project in Norway.
▪ Feasibility studies on deployment at further sites.
Direct capture - LEILAC
Approach:▪ Indirect heating of limestome.
▪ Capture during calcination in separate gas stream.
Next steps:▪ Electrification or utilization of alternative
fuels in Belgium.
▪ Construction of large scale demonstratorin Germany.
Approach:▪ Cement production with pure oxygen.▪ Looping of gas stream to increase CO2
concentration in flue gas.
Next steps:▪ First of kind pilot installation in Germany.
