  1. 1. GEOPOLYMERS WITH GREEN LIQUOR DREGS : An investigation of the possibility tomanufacture a geopolymer based on residual streams

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Martin Sundqvist; [2021]
    Nyckelord :;

    Sammanfattning : The pulp and paper industry make up a large part of the Swedish industry and is alsogrowing worldwide. With its growth, the amounts of residuals that are produced alsoincrease. The estimated annual global amount of residuals generated from pulp millsexceeds 1 million tons. LÄS MER

  3. 2. Transformation of lignin into biobased thermoset

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Linnea Cederholm; [2018]
    Nyckelord :lignin; microwave heating; solvolysis; biobased thermoset; lignin; mikrovågsbaserad teknik; solvolys; biobaserad härdplast;

    Sammanfattning : Combined microwave assisted extraction/degradation of technical lignin in green solvents was successfully employed to generate polyphenolic oligomers with lower Mw than the starting material. For Lignoboost, the highest liquid yield (65 %) was obtained in 20 min at 160 °C using ethanol as solvent. LÄS MER

  5. 4. Egenskaper hos stärkelse-lignosulfonatblandningar för möjlig användning som livsmedelsförpackningar

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :EVA ÝR ÓTTARSDÓTTIR; [2015]
    Nyckelord :Lignosulfonate; Starch; Food packaging; Mold casting; Bio-plastic;

    Sammanfattning : The demand for bio-plastics is constantly growing, due to the increasing use of synthetic plastic, their non environmentally friendly properties and long degradation time. This thesis explored the possibility to use starch-lignosulfonate mixtures for food packaging. LÄS MER
