Our process gives us the unique opportunity to produce high quality products adapted to our customers' high demands. The production is done with great environmental concern in the world's one and only closed-loop and chlorine-free bleach plant.
The raw material, softwood, is procured mainly from Swedish sustainable forestry. Annually we consume ca. 1.4 million cubic meters.
The wood is debarked and chipped and then fed together with cooking chemicals into the digesters. The bark is burned and provides energy in the form of steam. After cooking the cellulose is washed. Subsequently, it is bleached with hydrogen peroxide in the closed-loop bleach plant. The bleached cellulose is dried, sheeted and packed in bales. The whole process from log to finished bale takes about 40 hours.
During the cooking process hemicellulose and lignin is dissolved. The hemicellulose is then fermented and distilled into bioethanol. The lignin is processed in the cooking process into lignin before being dried.
In the power plant we recycle cooking chemicals and get energy in the form of steam which is used in our processes.
Our main products are cellulose, bioethanol and lignin but the biorefinery also produces more and more complementary products, such as carbon dioxide, biogas, bioresin and soil improvers.
