− 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

Heating of raw material to 1.450˚C

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.
