Valmet to supply new flash drying, baling line and CTMP rebuild to SCA Ortviken

Finland-headed forest industry and energy technology provider Valmet Oyj has announced that it will deliver a new flash drying and baling line and a rebuild of the existing integrated thermomechanical pulp (TMP) production line at SCA’s Ortviken mill in Sweden into a chemi-thermomechanical pulp (CTMP) market pulp line, which will have a capacity of 300 000 tonnes per annum.

SCA Ortviken in Sundsvall, Sweden, is a mill site in transformation. From having been one of the world’s largest publication paper mills, SCA announced in September 2020 that it is investing some SEK 1.45 billion (≈ EUR 139.43 million) into one of the world’s largest production lines for CTMP, using the parts of the infrastructure from the production of TMP and publication paper.

There is also the production of green energy on the mill site, supplying the Sundsvall district heating grid.

We are very excited to collaborate with SCA and to be selected as a partner for this conversion of the Ortviken mill to CTMP pulp production. We are convinced that this Valmet delivery will provide the best performance, and the pulp product mix required, to meet SCA’s high expectations for this project, said Andreas Lindstedt, Corporate Account Manager, Services, Valmet.

Valmet and SCA have together developed a concept to produce CTMP at the best possible operating expense using a combination of existing and new equipment. The unique chip treatment method, part of the HT-CTMP line currently used at SCA’s Östrand mill, will be utilized also in the rebuilt line at Ortviken.

The flash drying line includes two high consistency output TwinRoll presses for dewatering, Slab presses for bale forming, and a baling line with a Wrapper applyer using paper as wrapping. Additionally, two identical flash dryers, developed with a focus on energy efficiency, are part of the delivery including engineering, installation, training, start-up, and commissioning.

The delivery and installation of the equipment will take place during 2022 and the start-up of CTMP production is scheduled for the beginning of 2023. Although the value of the order has not been disclosed, according to Valmet, a project of this size and scope is typically valued at EUR 40-50 million.

Both SCA and Valmet are built on a long industrial history and our joint efforts go back to the year 1930 when SCA’s Östrand mill was built in Sundsvall, Sweden. Our companies have a strong focus on more sustainable development as well as safety and quality. We are very proud to be the selected partner when SCA takes the next steps forward into the future, said Rickard Andersson, VP Fiber Processing Business Unit, Pulp and Energy, Valmet.
