As a result of the upgrades, the facility can now use OCC (Old Corrugated Containers) instead of less contaminated recycled board as a raw material for the production of high quality linerboard. In addition, the upgrade ensures minimal fiber loss during the production process.

The main upgrade consisted of improving the current pulper detrashing loop using Voith’s IntensaMaxx. IntensaMaXX prevents tail formation and spinning so that even content with high levels of contaminant can be easily processed. Another advantage of IntensaMaXX is its low energy consumption. In addition, Newark Fitchburg upgraded a multi-stage fine cleaning system with Voith’s unique HCL5C cleaner with HW and LW removal combination, while adding a three stage fine screening upgrade with the C-bar screen basket. These upgrades included a new third stage MultiMizer with optimum slots configuration for a fiber savings final stage screening concept.
