Heidelberg Materials updated information about the Airvault GOCO2 project in France. In the Airvault cement plant the existing 2 semi-wet kilns are replaced with a new 4000 tpd kiln line from German plant supplier thyssenkrupp Polysius by 2025. The new plant (illustration) will save about 30% of CO2 emissions with improved plant efficiency, lower clinker factor and higher alternative fuel rates. About 1.0 Mta of CO2 from the limestone calcination in new kiln shall be captured, starting in 2030. The CO2 will be liquefied and finally transported by ship to geological storage under the North Sea. The project is part of the GOCO2 (Grand Ouest CO2) initiative in the West of France, with participation by Heidelberg Materials, Holcim, Lhoist and others.
