Forestry Research

Boosting the forest economy's ability to compete on a sustainable basis, by developing genetic materials and forestry techniques that help increase yields and improve the properties of the wood produced, all at lower costs and with less environmental impact.

Nurseries Able to produce 12 million plants a year, the nurseries supply the Group's forest planting operations.

+130 species of ornamental plants and shrubs

Delivering the Wood

The wood is delivered to the The Navigator Company's industrial units.

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.

Processing the Bleached Pulp

Paper Manufacture

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.
6 Processing and Dispatch

Paper is:

Derived from a renewable raw material: wood.

White pulp

White pulp (made up of cellulose fibres) can be delivered to the paper mills in two ways:
