Metsä Group Shuts Down Kemi Bioproduct Mill in Finland Due to Gas Explosion

March 26, 2024 - A gas explosion occurred at Metsä Group's Kemi bioproduct mill in the evaporation plant during welding work on Thursday 21 March 2024. Three people were slightly exposed to hydrogen sulphide and were referred for a health check. The persons have returned to work after the check-up.

After securing the area, an investigation into the material damage was launched. According to current information, the repair work will take 10 - 12 weeks. The production will be started when the repair work has been completed and the safe operation of the mill has been ensured.
