Wallenberg Wood Science Center (WWSC) is a research center with a focus on New materials from trees. Activities of WWSC are funded by the Knut and Alice Wallenberg Foundation.

The development of new wood-based materials is of great interest to the forest industry. Wood tissue is composed of a complex biopolymer mixture containing cellulose, hemicelluloses and lignin. Covalent bonds between lignin and different polysaccharides form closely associated structures known as lignin-carbohydrate complexes (LCCs). As a result, the successful extraction and separation of wood polymers poses a major challenge for materials biorefinery concepts. Enzymes that target lignin-carbohydrate (LC) bonds are especially useful for biorefinery applications as they can facilitate the isolation of individual wood components in combination with mild chemical treatments.

The aims are:
  • to separate the different biopolymers with increased efficiency and with only limited degradation of the wood polymers
  • to discover and characterise enzymes for wood processing and valorisation
  • to apply enzymes to extract wood components in their native and polymeric form
WWSC is a collaboration between Chalmers and KTH.
