Mix of measures instead of individual solutions
Various approaches already exist in the industry to make concrete production more sustainable. For example, alternatives to sand and gravel are already being used in mixes. Much effort is also being put into pursuing and optimizing the replacement of cement through the use of granulated blast furnace slag and similar options. This will also help to further reduce the footprint of currently around 521 kg CO2 per t of cement. In the area of negative emission technologies (NET), there are promising approaches to capture the emitted CO2 at the cement plant stack using CCS (carbon capture and storage) technology.
Our technology is already applicable, has enormous potential worldwide, and requires no additional energy input. In particular, however, the incorporation of Clim@Add® can be combined with most other developments. We are therefore convinced that the carbon sinks we create will make a lasting and significant contribution to reducing the global concrete footprint.
