INTRODUCTION:
“We’re up and running with our brand new CTMP facility - on-time and on budget. Equipped with the latest technology - not only
providing unique opportunities for customized solutions but also an even broader technical portfolio. We already have a profitable business,
a solid, growing customer base and we see growth in packaging and tissue, but also in new areas such as moulding, where we foresee a
high future demand. Replacing fossil plastics with certified fibre-based solutions will certainly be an interesting area, so with the broadest
CTMP portfolio in the market, we’re now taking a significant leap forward”, states a proud Stefan Sjöström, Director of Global Sales,
CTMP.

The biggest challenge, apart from the fact that we had a
global pandemic to deal with during the project, affecting not only
us but also our contractors and naturally logistics, was to tear
down large parts of the closed paper mill at Ortviken and build a
new bleached CTMP (Chemi Thermo Mechanical Pulp) facility at
the same time. “Simply squeezing a new process into an existing
costume”, is how Anders Granström, Mill Manager at SCA’s new
state-of-the-art CTMP facility puts it.
Ortviken’s Industrial site
The industrial activity at Ortviken began as early as the
middle of the 19th century. During the 20th century, Ortviken
developed into a modern industry and in 1958 two paper machines
were put into operation. At its peak, the factory had a production
capacity of approximately 900,000 tons of publication paper, but in
February 2021, production ended and the last paper machine was
closed.
However, SCA had already decided to move the CTMP
production from Östrand to Ortviken and invest SEK 1.45 billion in a
new facility, thus significantly reducing the investment cost per ton,
largely thanks to a well-developed infrastructure and modern parts
already in place. This included key functions such as wastewater
treatment, steam supply, electricity, and compressed air. Add to
that the strategic location of the site, meaning that SCA can offer
logistics solutions worldwide, although Europe will continue to be the
main market for CTMP.

“At the very least, we can also
leverage solid and unique expertise
in mechanical pulp that exists both in
Ortviken and Östrand. Although our new
facility uses cutting edge technology and
is highly automated, CTMP production
still requires experienced operators
who constantly monitor and really
understand the process - and we have that
competence”, says Anders.
