  1. 6. Recovery of Hemicelluloses Extracted from Spruce and Wheat Bran : Membrane Filtration Process Development and Cost Estimates

    Författare :Johan Thuvander; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemicelluloses; Membrane filtration; Galactoglucomannan; Arabinoxylan; Microfiltration; Ultrafiltration; Spruce; Wheat bran; Hemicellulosa; Membranfiltrering; Mikrofiltrering; Ultrafiltrering; Arabinoxylan; Galactoglucomannan; Gran; Vetekli;

    Sammanfattning : Hemicelluloses are a group of abundant polymers found in all plants and constitute about one third of the total plant biomass. These polymers can be used in many different products, such as oxygen barrier films, emulsifiers, foams and probiotic food additives. LÄS MER

  3. 7. Agro-Waste Derived Additives for Polylactide and Tapioca Starch

    Författare :Edwin Azwar; Minna Hakkarainen; Anna Wistrand; Christian Glandfils; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agro-industrial waste; wood flour; rice bran; polylactide; starch; biomass; degradation; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    Sammanfattning : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. LÄS MER

  4. 8. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Författare :Sara Jonsdottir Glaser; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Sammanfattning : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries. LÄS MER

  5. 9. Integration of first and second generation bioethanol processes using edible filamentous fungus Neurospora intermedia

    Författare :Ramkumar B Nair; Högskolan i Borås; []
    Nyckelord :First- and second-generation bioethanol; Integration; Neurospora intermedia; Edible filamentous fungi; Wheat straw; Wheat bran; Whole stillage fiber; Biochemistry; Biokemi;

    Sammanfattning : Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. LÄS MER
