  1. 1. Faktorer som påverkar blekning av cellulosa : En dataanalys vid bioraffinaderiet Domsjö Fabriker AB

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Joe Lindehag; [2023]
    Nyckelord :pulp; biorefinery; statistics; data analysis; Cellulosa; bioraffinaderi; statistik; dataanalys;

    Sammanfattning : Domsjö Fabriker AB har under en tid haft en stigande vattenförbrukning utan att kunna peka på någon bidragande faktor. Som ett led i denna utredning har en dataanalys över blekeriet med fokus på variabeln Chemical Oxygen Demand (COD) genomförts. LÄS MER

  3. 2. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  4. 3. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ângelo Miguel Mendes Ferreira; [2023]
    Nyckelord :biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Sammanfattning : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

  5. 4. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Ali Al Husseinat; [2023]
    Nyckelord :Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Sammanfattning : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. LÄS MER

  7. 5. Protein digestibility of biorefined juice from fresh and ensiled ley crops in growing pigs

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Jhon William Perez Davila; [2023]
    Nyckelord :protein digestibility; amino acids; ley crops; silage; biorefinery; press juice; growing pigs;

    Sammanfattning : The study aimed to evaluate the protein and amino acid digestibility of press juice from biorefined ley crops in the form of fresh (FPJ) and silage (SPJ) when included as an ingredient in liquid diets for pigs. The juice was extruded from ley crops mixture (grass-clover). LÄS MER
