Landslide in Halden has stopped Norske Skog Saugbrugs PM6

There was a landslide at Norske Skog Saugbrugs around 04:30 CET today on 27 April 2023. This has had a material impact on building structures, cranes, and other machinery and equipment relating to PM6, which will result in a production stop for a longer period.

"There has been a significant landslide which has caused great damage to the building structure for PM6 at Saugbrugs. We are working to get a full overview of the situation and risk of further landslides, but at the moment it is considered too dangerous to enter the area. This will result in a production stop on PM6 for a longer period. Most importantly, no one were harmed in the landslide, but it has been a traumatic and shocking experience for all involved and the local community" says Sven Ombudstvedt, CEO of Norske Skog ASA.

Saugbrugs PM6 has a capacity of 260 000 tonnes SC magazine paper. Operations at Saugbrugs PM4 continue, the machine has a capacity of 100 000 tonnes SC magazine paper.
