Pilot Plant Produces Climate-friendly Cement Clinker
To produce belite cement clinker, the pilot plant uses an all-electric heating system powered by renewable energy and a carbon dioxide atmosphere, reducing the energy required for the process. "We can manage with a process temperature of 1000 instead of 1400 degrees Celsius in the rotary kiln," Stemmermann said.

Cement plants have used new grinding equipment, dry-process instead of the wet-process kiln, modern clinker kilns, and multi-stage preheaters that can save energy [1]. The use of blends with renewable fuel and fossil fuel [ 2 ] or the use of solar calcination reactors [ 3 ] can reduce emissions and save energy in cement manufacturing.
