Finland: The VTT Technical Research Centre of Finland and Finnsementti have revealed work on the Decarbonate project to test a 12m electrically-heated rotary kiln. Other partners on the initiative included Nordkalk and UPM. Precalcination was tested as well as the projection of quick lime. The eventual goal is to use electricity from renewable sources to power the kiln and then capture the CO₂ released for utilisation.

The Decarbonate project has been exploring CO₂ capture and utilisation concepts that can be commercialised. It has run for two years since late 2019 and has funding of Euro1.2m. It has also looked at oxyfuel and electrolysis experiments.
