  4. 3. Towards sugar- and lignin-based polyesters and polyurethanes with enhanced properties

    Författare :Niklas Warlin; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyesters; Polyurethane; Bio-based Materials; HMF; Recycling; Vanillin;

    Sammanfattning : The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. LÄS MER

    Sammanfattning : Lignin is one of the three predominant biopolymers that make up plants together with cellulose and hemicellulose, and it is the only plant component that is based on aromatic units. The industrial kraft pulping process generates large amounts of lignin, which is currently used to generate heat for the process. LÄS MER
