Keep the good and add the better

Dear readers,

2045 is approaching, the self-declared goal of at least the German cement industry to produce climate-neutral cement by then. However, this also presents the protagonists with challenges, but also offers great possibilities and opportunities for technical and scientific development. One prerequisite for keeping pace with this is to stay informed, think ahead and keep an eye on current developments. Dr. Joachim Harder‘s contribution from Onestone Consulting “The future generation of cement kiln technology” is certainly a contribution to this. Kiln technology is also always linked to the respective CCS technology, which will be used to separate CO₂ from the production process in the future. The kiln systems used to date have of course been extensively researched, there is a lot of experience, the technology is well understood. How can I perhaps transfer this knowledge to future systems? Find out more in this exciting article from p. 22.

The topic of CO₂ is a recurring theme in this issue. Under the motto “CarbonCycleCultureClub (C4): ‘Closing the Loop / Carbon Credits/Carbon Pricing’”, Forum Rathenau discussed the CO₂ market, which was also a focus of the UN Climate Change Conference in Baku. A comprehensive report starting on p. 42 deals with many of the aspects discussed, also with regard to the cement industry. At the end of the event, there were also many new approaches. Prof Wehrspohn concluded with the words: “Which is good, because the idea of the CarbonCycleCultureClub is also to ask questions and not answer them all.”

Many technical articles are also included in this issue, e.g. from the company Christian Pfeiffer “Enhancing cement grinding efficiency: Replacing intermediate diaphragms in ball mills”.
