Under the deal, Valmet will supply paper machine grade conversion rebuild and a wide scope of automation for Italian firm’s Verzuolo mill.
In the project, originally Valmet-supplied paper machine PM 9 and associated stock preparation systems, which are being used to manufacture lightweight coated (LWC) paper grades, will be rebuilt to produce recycled containerboard grades.
The equipment is currently involved in the production of lightweight coated (LWC) paper grades.
Valmet noted that the total value of an order of this type will be between €40m and €60m.
The project is part of Burgo Group’s strategy to focus on containerboard grades and diversify its solutions ranging from publishing to packaging and printing paper to paper for corrugators.
