The idea behind our softwood concept is wood segregation. Three kinds of raw material enter Södra’s woodyards; softwood thinnings, roundwood and sawmill chips. These different materials are mixed carefully  to achieve different paper properties.

Sawmill chips

This is how we have designed our softwood product groups. Sawmill chips are the main component of Södra green pulps, while our Södra black range is predominantly thinnings and Södra blue pulps are mainly roundwood.

Two of our mills, Södra Cell Värö and Södra Cell Mönsterås, use TCF (total chlorine free) bleaching sequences and the third, Södra Cell Mörrrum has an ECF (elementary chlorine free) bleaching sequence.

This gives Södra the possibility to produce and sell both TCF and ECF products. TCF pulps have a Z in the product name. A third component used in our branding is brightness, however all of our pulps are not fully bleached. Within all three groups we have pulp with 85 %ISO brightness and in the Södra green group we also offer a pulp with 70 %ISO brightness.

A fourth factor is the drying method, either sheet or flash dried. Flash-dried pulp has the letter F in the name.
