Customer case:

Kruger's grade conversion rebuild to linerboard

Jan 9, 2020

Kruger converted its newsprint machine in Trois-Rivières mill in Canada to produce the finest 100-percent recycled high-strength linerboard on the market, with the help of Valmet. Kruger also took advantage of Valmet’s piloting services to develop the rebuild scope. The machine was ramped-up with onsite expert support and remote optimization from the Valmet Performance Center, enabling it to reach its runnability, capacity and quality targets with outstanding results and steady start-up curve development.

Kruger PM10 and Anish Patel
Valmet presented us an integrated, overall solution in terms of technology and were willing to take a kind of calculated risk, too. Being one team with Valmet has been the key. This is not a customer-supplier relationship – it’s a true partnership.
