Customer success stories
Fast results at Nippon Paper Akita's bleaching process
Nippon Paper Group is one of the leading producers of paper and cardboard in the world and it's Akita mill the leading Japanese producer of paper, cardboard and pulp. Valmet implemented a new Valmet Kappa Q analyzer and the Valmet Bleaching Optimizer solution to reduce quality variability and to reduce bleaching chemical consumption.
Burgo Ardennes stabilizes bleaching process
Optimization smooths out bleach plant operation and demonstrates an 8.7% saving in bleaching chemicals with improved brightness stability in the Burgo Ardennes mill in Belgium.

Valmet Brightness Measurement
Valmet Brightness Measurement (Valmet Cormec5 X) exposes the latest developments of the optical in-line measurement technology invented some four decades ago by Valmet. It demonstrates the very same proven equipment features as the previous versions but in more versatile and compact package.
