  1. 1. An analysis of creating plastic material based on the microalgae Scenedesmus

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Isabelle Hernodh Svantesson; Saga Grånäs Jakobsson; [2019]
    Nyckelord :;

    Sammanfattning : The microalgae Scenedesmus Bloom are grown in sewage environment and contains, among other things, polymers of saccharides. The polysaccharides can possibly be extracted and used for the manufacturing of plastic material. The algae have a strong cell wall, can grow fast in severe external conditions and shows good ability to capture carbon dioxide. LÄS MER

  3. 2. Bioplastic material from microalgae : Extraction of starch and PHA from microalgae to create a bioplastic material

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Nathalie Johnsson; Fredrik Steuer; [2018]
    Nyckelord :Bioplastic material; Starch; PHA; PH3B; Extraction; Microalgae; Polymers; Bioplastiskt material; Stärkelse; PHA; PH3B; Extraktion; Mikroalger; Polymerer;

    Sammanfattning : Microalgae used in sewers to capture CO2 eventually turns into waste material. Through the use oftheir biomass, the waste algae can be given a new purpose. In this study attempts to extract starch or PHA from three different algae; Calothrix Scytonemicola, Scenedesmus Almeriensis and Neochloris Oleoabundans, were made. LÄS MER

  4. 3. Anaerobic Co-digestion of Sewage sludge, Algae and Coffee Ground

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Kristina Flisberg; [2016]
    Nyckelord :Anaerobic digestion; Algae; C.Vulgaris; Coffee ground;

    Sammanfattning : Energy shortfall and air pollution are some of the challenges the human kind is facing today. Fossil fuel is still the most widely used fuel, which is a non-renewable resource, increasing excess carbon dioxide into the air. LÄS MER

  5. 4. Renewable energy from wastewater grown microalgae - a concept for nutrient recycling and sustainable energy recovery

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Stina Lidén; [2015]
    Nyckelord :sustainable wastewater treatment; vattenförsörjningsteknik; avloppsteknik; renewable energy; nutrient reduction; nutrient recycling; microalgae; AnMBBR; biogas; Technology and Engineering;

    Sammanfattning : Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. LÄS MER

  7. 5. Effects of food quantity, dietary fatty acids and temperature on fitness of Daphnia magna : a factorial experiment with Scenedesmus acutus and EPA amendments

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Bernadette Pree; [2011]
    Nyckelord :Daphnia magna; temperature; Scenedesmus acutus; food quality; dietary fatty acid amendment; food concentration; pelagic food web;

    Sammanfattning : The performance of zooplankton has a major impact on the efficiency in trophic transfer in pelagic food webs and is therefore examined in this study. I investigated the effect of different food quantity and food quality, as measured by omega-3 fatty acid (ω3-FA) content on survival, somatic growth and reproduction of Daphnia magna at high and low temperatures in laboratory growth experiments.
