Södra is taking the next step in its innovation journey with the launch of Södra blue S – a new type of paper pulp that combines softwood fibres with oat hulls from Swedish grain processing. …Södra blue S has been developed to meet the growing demand for renewable materials and more circular use of resources. …The new process makes it possible to combine forest fibres and agrofibres directly in the pulp process, enabling Södra to increase yield and improve strength properties. Pilot trials show that blue S delivers enhanced strength properties and good runnability in paper production. Several trials have been conducted at Södra Cell Värö with very positive results. Towards the end of 2025, the conditions were established to enable campaign-based volumes. …Oat hulls, which previously had limited areas of use.
