  4. 3. Analysis and Valorization of Bark from Silver Birch, Scots Pine, and Norway Spruce : Compositional analysis of bark from common Swedish trees in forestry, to optimize sustainability procedures and monetary value of bark residue

    University essay from Umeå universitet/Kemiska institutionen

    Author : Isak Lindbäck; [2022]
    Keywords : ;

    Abstract : Silver birch, Scots pine, and Norway spruce are the three most common types of trees in Sweden and make up to 90% of standing volume in Swedish forests (Skogsstyrelsen 2015, 3). With millions of cubic meters of wood being cut down annually, bark and other residues that cannot be used for sawn timber is left over and burnt for energy. READ MORE

    Keywords : Norway spruce bark; bark biorefinery; extractives; cellulose; lignin; non-cellulose; polysaccharides; soxhlet extraction; hot-water extraction; organosolv extraction; PAA; delignification; carbohydrate analysis; 2D HSQC-NMR and FTIR; Granbark; bark bioraffinaderi; lignin; organosolv extraktion; hot-water extraktion;

    Abstract : Spruce Bark contains several fundamental main substances; lignin, non-cellulose polysaccharides, cellulose and extractives. This undergraduate study focuses on developing a process to extract each of these components from spruce bark using a biorefinery concept, with a main focus on extracting lignin without degradation.
