Rottneros Mill is increasing
its CTMP capacity
Rottneros Mill in Sunne, Värmland
Rottneros Bruk focuses on the development and production of chemically pretreated thermomechanical pulp (CTMP). The pulp is used in the production of cardboard, packaging, tissue paper, filters and fiber cement.
The Group has invested a total of 220 MSEK in increased production during 2023–2024. The mill's capacity is now 165,000 tons annually, up from the previous 125,000 tons/year.
In 2024, a solar park and a battery storage system were installed as part of the Group's efforts to increase the share of renewable electricity while also reducing exposure to the electricity market. The solar park is expected to generate approximately 3 GWh per year. Investments in renewable electricity totaled 85 MSEK.
The mill has produced mechanical pulp since 1887.
Spring by Rottneros is our brand name för CTMP.
95% of the wood is fully utilised in production.
Production of CTMP in 2024 amounted to 122,100 tons, which is the same as the previous year.
In the production of CTMP, 95 percent of the wood can be utilized, and more than two-thirds of the energy used is fossil-free.
The solar park is expected to generate nearly 3 GWh annually, compared to the group's total annual purchased electricity demand of approximately 220 GWh.
CTMP Mechanical pulp
Rottneros CTMP offers high purity, strength and rigidity with low weight – valuable properties for cartonboard manufacturers. CTMP can be customised for a number of different special applications where freeness, porosity or bleaching level is crucial.
How the mill’s CTMP is used
Cartonboard
Mechanical pulp makes it possible to produce a thicker, and therefore more rigid cartonboard from the same amount of raw material.
Special applications
Mechanical pulp can be customised for a number of different special applications where freeness, porosity or bleaching level is crucial.
Pulp for fibre trays
The raw material for our own water molded fiber trays consists of 100% mechanical pulp from pure forests.
A tribute to the groundwood line - an important part of our mill’s history
Watch the film about Rottneros Mill’s groundwood line which started up in 1887 and was closed down in December 2022, after 135 years of production, the last of its kind in Sweden in recent years.
The main reasons for the closure were long-term negative prospects for printing paper and deterioration in the electricity market.
Participating in the film are former employees who share memories of how the timber was floated and transported via ropeway.
