The Duisburg-Walsum mill
Paper bridging industry and nature

In the Duisburg­Walsum mill 520 em­
ployees produce around 400 000 tonnes
of printing paper in reels on two pro­
duction lines (each consisting of a paper
machine and a coating unit).

The mill is located in the industrial area
of the Duisburg­Walsum district. Its
premises cover a surface area of 44 hec­
tares half of which is developed. Situated
directly on the bank of the River Rhine,
the mill has a quay of its own and is bor­
dered by residential areas on two sides.

In the immediate vicinity of the plant
is the 550 hectare “Rheinaue Walsum”,
which has belonged to the internatio­
nal wetland “Unterer Niederrhein” since
1993. The “Rheinaue” became an envi­
ronmental conservation area in 1990.
There are over 200 types of birds and
380 different types of fauna to be seen in
the area.

High temperatures and anaerobic con­
ditions in the closed water circuits of pa­

to “rot” quickly. Sulphate contained in
the process materials is transformed into
sulphide that is then discernible as a hy­

prevent this odour, we make sure that
the circuit water flows at a high speed
and that all water equalising and buffer

1) Humidity content of the accumulated fibre/pigment residues (2006: 39 %, 2007: 35 %, 2008: 36 %).
2) The increase in consumption in 2008 resulted from feeding external steam into the paper machine water
   circuits to achieve an improved seasonal uniformity of the circuit temperature thus ensuring a higher process

3) Calculated by water balancing, higher cooling water quantity in 2008 results from a changed balance
   calculation and optimisation of measures taken on cooling units in the area of the TMP facility.

22 Norske Skog Environmental Statement 2009

Based on site inspections, conversations with the company’s staff, documents
and records perused, I confirm that the environmental policy, the environmental
targets, the environmental program, the environmental management system and
the procedures for assessing the environmental impact of the
                 Organization Norske Skog Walsum GmbH
            Theodor­Heuss­Straße 228, 47179 Duisburg (Germany)
correspond with the regulation (EEC) 761/01 in its version dated February 3, 2006.

The data and details of the consolidated environmental declaration are reliable.
They provide an adequate and correct image of the environmental relevance of
all actions at the respective sites. This was verified by random on­site inspec­

There is no evidence of any deviation from legal provisions.

The next simplified environmental declarations will be published
in November 2010, 2011.
