UPM, Kaukas
UPM in Kaukas
The Kaukas mills are located on the shore of Lake
Saimaa in the city of Lappeenranta in Southeast Finland.
There are several UPM production facilities and units in
the mill area, including a pulp mill, paper mill, sawmill,
UPM Living, the Research Centre and Kaukaan Voima
Oy.
The Kaukas pulp mill produces bleached softwood and
birch pulp. Some of the softwood pulp is used by the
Kaukas paper mill. The paper mill manufactures coated
magazine paper on two production lines. The Kaukas
sawmill manufactures sawn redwood, part of which is
further processed into planed products at Kaukas.
Kaukaan Voima Oy (KauVo) has a biofuel power plant in
the Kaukas mill area. The power plant generates heat
and electricity for the Kaukas mills and the power company Lappeenrannan Energia Oy. 80% of the district
heating energy required by the town of Lappeenranta is
generated using green biofuel.

This publication, UPM Kaukas Environmental Performance in 2011, is the
mill’s appendix to the shared Environmental Statement 2011 for UPM paper

appendices, forms UPM’s joint EMAS statement. The Environmental Statement for UPM pulp and paper mills is available at www.upm.com.
UPM’s next joint EMAS statement will be published in the spring of 2013.

There was an increase of approximately 7% in CO2 emissions
due to the increased operating speed. CO2 emissions from fossil fuels were reduced by around 4% because less natural gas
had to be used as a secondary fuel than in the previous year.
CO2 emissions produced from fossil fuels during energy production were reduced, as less natural gas had to be used in the
production of energy than previously. Most of the energy was
produced using biofuels.

Waste
The Kaukas mills’ joint environmental objective in 2011
SOLID WASTE (dry weight, t/a)
was to further reduce the amount of waste by 5% from
the previous year’s level. This objective was achieved:
The amount of waste in dry tonnes was reduced by 25%
and in wet tonnes by 17% from 2010. In 2011, 9536

The pulp mill generated 5800 tonnes of waste to be

2010. The paper mill’s waste volume increased by 16%

the pulp and paper mill. The volume of coating colour
sludge, which is the paper mill’s largest proportion of
process waste, was reduced by 2% from the previous
year. The pulp mill’s share of the waste transported to the
Tuosa landfill amounted to 60%. In dry tonnes, the largest proportion of waste was the green liquor dregs from
the pulp mill, and the waste that took up the most space
was the paper mill’s coating colour sludge. Research is
being conducted into the options available for reuse.
In 2011, 34,232 tonnes of the waste generated by the
Kaukas integrated mills was reused, which amounted to
77% of the total waste volume. Virtually all (99.96%) of
the waste generated by Kaukaan Voima Oy was reused.
67% of the pulp mill’s waste and 15.2% of the paper
mill’s waste was reused. Finding opportunities to reuse
the paper mill’s waste has proven to be quite challenging.
The storage field at the Tuosa landfill was further
expanded by approximately one hectare in the summer
of 2011. As in 2010, a mixture of green liquor dregs
and fly ash was used as the earthwork construction material and fly ash was used as the foundation material. The
plan is to continue expanding the field structure each
year.
