Valmet’s grade conversion delivery will include a new approach flow system, modifications to the headbox, a shoe and blade technology upgrade in the forming section, and a new OptiPress Center press section to improve drying and runnability
Valmet will supply a grade conversion rebuild to VPK’s Alizay mill in France. In the project, the paper machine, which currently produces fine paper grades, will be rebuilt to produce recycled lightweight containerboard grades to support Alizay’s plans for long-term sustainable development in circular economy. The start-up is scheduled for the end of 2022.
The order is included in Valmet’s orders received of the fourth quarter 2021. The value of the order will not be disclosed.
“We have excellent relations with VPK Group from earlier projects, for example Blue Paper’s grade conversion rebuild in France. I felt we were able to adapt well to the customer’s needs in this project as well: as the machine in question is familiar to us, we were able to offer proven and reliable technical solutions that fulfilled the requirements cost-efficiently,” says Markus Laitila, Director, Large Projects, Valmet.
