  1. 1. Geobacillus 7349 – A new potential biosurfactant producing microorganism

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Zhuoying Deng; [2023]
    Keywords : biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

    Abstract : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. READ MORE

  2. 2. Chemical modification of starch in order to get thermoplastic properties

    University essay from KTH/Materialvetenskap

    Author : Emma Hallbert; Elsa Wadman; [2023]
    Keywords : thermoplastic starch; dialdehyde starch; schiff-base; imine chemistry; termoplastisk stärkelse; dialdehydstärkelse; schiffbas; iminkemi;

    Abstract : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. READ MORE

  3. 3. Towards a sustainable substitute for Acrylonitrile Butadiene Styrene (ABS) in automotive industry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Amalia Christoula; [2023]
    Keywords : Polylactide PLA ; Biobased; Life Cycle Analysis LCA ; Impact modifiers; Lignocellulose nanofibers LCNF; Polylaktid PLA ; Biobaserad; Livscykelanalys LCA ; Slagtålighet; Nanofibrer av lignocellulosa LCNF ;

    Abstract : Syftet med detta examensarbete var att utveckla ett hållbart ersättningsmaterial till akrylnitrilbutadienstyren plast (ABS), genom att applicera principerna för grön kemi och teknik. ABS är en icke-nedbrytbar plast som till exempel används i slagtåliga produkter för hyttinteriörer. READ MORE

  4. 4. Biodegradation Experiments of Polymeric Materials: Monitoring and Analysis

    University essay from KTH/Fiber- och polymerteknologi

    Author : Sini Ojala; [2021]
    Keywords : Biodegradation; Composting; Differential scanning calorimetry DSC ; Fourier Transform Infra-Red FTIR spectroscopy; Natural Environment; Open environment; Tensile test; Biologisk nedbrytning; Differential skannings kalorimetri DSK ; Dragprovning; Fourier Transformer Infra-Röd FTIR spektroskopi; Kompostering; Naturlig miljö; Öppen miljö;

    Abstract : Plastskräp har blivit ett global problem på grund av nedskräpning och otillräcklig avfallshantering. Användning av biologiskt nedbrytbart material kan underlätta problemet, även om det inte är en universallösning. READ MORE

  5. 5. The effects of pH and biodegradation on polymer-based granules

    University essay from Lunds universitet/Bioteknik (master)

    Author : Isak Svenningsson; [2021]
    Keywords : polymerteknik; biopolymer; bioteknik; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Abstract : The use of biopolymers instead of traditional fossil fuel based and non-biodegradable polymers is seen as a positive step forward towards a more environmentally friendly future. This project investigates a granule product that is used in a dishwashing system with the aim of gaining knowledge about how it is affected by the storage in between uses and its biodegradability.
