Sweden: SaltX has begun industrial-scale testing of electrified pre-calcination of cement raw meal from Holcim at its test and research facility in Hofors, completing an initial test phase with ‘positive results’, according to SaltX. This follows earlier, smaller-scale testing, where targeted calcination levels were achieved. SaltX said that the tests establish a solid foundation for scale-up towards a fully electrified pilot plant. The tests form part of a concept validation phase running in spring 2026 comprising multiple test periods, each of which process around 20t of cement raw meal.
The pilot plant is planned for 2028. SaltX and Holcim said further updates on the testing programme will be provided before summer 2026.
