Norske Skog - Reusing Solid Waste

Norske Skog Australasia operates an integrated pulp and paper mill at Albury, New South Wales, which currently manufactures about 210,000 tonnes of newsprint each year.

The major solid waste product produced by the mill is a solid waste product called "biosolid", which is derived from two main sources:

• Unused wood fibre and sludge; and
  
• Unused recycled fibre, waste ink and magazine fillers.

Traditionally, these biosolids have been sent to landfill.

In the early to mid 1990s, Norske Skog conducted a range of biosolid reuse trials. These included worm farming, soil erosion control and application on agricultural land.

Norske Skog has now developed a full-scale biosolids spreading operation on privately-owned land within a 25 km radius of the mill. This operation was chosen as the preferred method of reuse because the material proved useful as an agricultural soil conditioner, providing organic matter, nutrients and calcium as a lime substitute.

The spreading of biosolids on farmland near Norske Skog's Albury mill saves current landfill space and avoids the need to develop a new landfill in the future. It also provides benefits for local farmers who are able to use material previously sent to landfill to improve the productivity of their farmland.
