1. Towards molecular weight-dependent uses of kraft lignin
Abstract : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. READ MORE

3. Towards bacterial valorization of low molecular weight lignin
Abstract : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. READ MORE

4. Precipitation of Kraft Lignin: Yield and Equilibrium
Abstract : Kraft pulping is the dominant pulping process used in the world today. The material efficiency in modern kraft pulp mills is, however, only 40−55% and the final product consists mainly of cellulose. Recently, a novel process called “LignoBoost” has been introduced to separate lignin from kraft black liquor. READ MORE

5. Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries
Abstract : Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. READ MORE
