VTT electric kiln targets carbon neutral cement production

09 December 2022, Published under Cement News

VTT Technical Research Centre of Finland has developed an electric rotary kiln that is capable of making cement production close to carbon neutral. Powered by low-emission electricity, the kiln enables the capture of pure CO2 when lime is burned in the pre-calcination phase of cement production. VTT has successfully completed several experiments using different feedstocks between November 2021 and October 2022, with the participation of Finnish cement producer Finnsementti and Nordka...
