The Setubal Mill started up in
1964. First, batch digesters were uti-
lized to produce about 100,000 t/a of
bleached and unbleached eucalyptus
and Portuguese pine pulps.
In 1979, a complete pulp line with a
continuous digester was added and
production increased to 260,000 t/a of
fully bleached eucalyptus. In 1989, a
major modernization occurred, both
for quality and environmental reasons.
This included a new continuous
digester, a new recovery boiler, and
the closure of the 1964 pulping line.
The mill is located in the heart of
some natural preserve areas, so envi-
ronmental issues are very important.
Since 1995, the mill has been
de-bottlenecked and fine-tuning
operations were implemented (e.g.
increased evaporation capacity, modi-
fying one digester to expand the
cooking zone, etc.). Total output of
the pulp mill is now 480,000 t/a.
