for their breakthrough research and innovation creating a platform for large-scale separation, isolation, purification and applications of chemical components in wood. The Laureates have created an understanding of the fundamental chemistry of spruce tree knots, i.e. the part of the branches that is embedded in the stem. They developed technical separation methods to extract tree knots from the pulping process and isolate and purify chemicals from the tree knots, opening the field for the forest products industry to improve and broaden its role and commercial prospects with a range of new products and implications e.g. for chemicals, energy, production efficiency and sustainability.
