Delivering the Wood
The wood is delivered to the The Navigator Company's industrial units.+
Biomass
Preparing the wood
The bark is stripped from the logs which are then processed into chips of a standard size.

Pulp Manufacture
The next stage in the process of preparing the wood consists of cooking it, to separate the cellulose fibres from the lignin. The result is a brownish-coloured raw pulp.

Paper Manufacture
+
Processing the Bleached Pulp
Pulp is processed by the machinery into sheets of paper over
three distinct phases:
+
Wet End
The wet pulp is processed into continuous sheets.Pre-Dryer
Water is extracted by pressing.
+
Post-Dryer
Moisture is evaporated by using heat.

Jumbo Reel
The paper is wound on the reeler into jumbo reels. It takes around 60 minutes to produce one jumbo roll of paper weighing 80 tons.+
Processing the Paper
Reamer
The paper is sorted into stacks of 500 sheets: these are called “reams”.
Ream Wrapping
Reams are wrapped, packaged and then palletised.
Dispatch
The Group's products are dispatched by road, sea or rail. We export to 123 countries around the globe. Learn more +
