The start-up of Kotkamills' rebuilt board machine 2 (BM2) in Finland took place on July 22, 2016. Valmet supplied key technology and automation package for the extensive paper machine grade conversion project. The printing paper (MFC) production line was converted to produce a range of folding boxboards and food service boards.
"Our BM2 is the first machine in the world to have the capability to produce dispersion barrier coatings directly on the machine, producing barrier boards that can be recycled with normal paper waste due to having zero plastic content. The interest in our new sustainable products has been massive. The new machine offers a wide range of interesting possibilities for converters, brand owners and designers alike," says Markku Hämäläinen, Chief Executive Officer of Kotkamills.

"The project schedule was really tight; from the change of the ownership of Kotkamills to start-up in less than sixteen months. That is extremely fast. I am very pleased with cooperation with Valmet and how well-prepared Valmet's project organization was for such an extensive project," says Stefan Fors, Project Director of Kotkamills.
