Nippon Dynawave: sustainable board with less CO2 emissions and fibers
Nippon Dynawave wanted to go towards a more sustainable board production. They succeeded in reducing greenhouse gas emissions and using less fibers for the same amount of board with the Valmet-supplied metal belt calender.
Putting a metal belt calender on our paper machine allowing us to use less fibers to make the same quality board for our customers is really revolutionary to this business."
We chose Valmet as a supplier after doing extensive pilot work - investigating the technical solution they proposed."
The results with the metal belt calender were actually better than with the pilot scale projections. So it has been quite an asset to Nippon Dynawave to make better paper while reducing fiber demand."
