  1. 11. The blue-end of the spectrum of plastics : A step toward understanding the role of blue biopolymers in phasing out fossil plastics

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Alice Rudberg; [2021]
    Keywords : plastics; polymers; bioblends; bioplastic; biopolymer; renewable; biodegradable; biobased; algae; seaweed; blue plastics; blue biopolymers; blue growth; Plaster; polymerer; bioplast; biopolymer; förnyelsebar; nedbrytbar; komposterbar; biobaserad; alger; sjögräs; algplast; algpolymerer; blue growth;

    Abstract : For more than a century, plastics have become an increasingly important part of the human society. Thanks to the durability and the many varieties of plastic it has a wide range of applications, but unfortunately the traditional plastic made from fossil oil has its drawbacks. READ MORE

  3. 12. Engineering Rhodosporidium toruloides for the production of polyhydroxybutyrate

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Tova Lindh; [2021]
    Keywords : Applied microbiology; Bioplastics; Rhodosporidium toruloides; Polyhydroxybutyrate; Non-conventional yeast; Oleaginous yeast; Biology and Life Sciences;

    Abstract : The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin.

  4. 13. 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.

  5. 14. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE

  6. 15. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Beyar Abdulla; [2020]
    Keywords : Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Abstract : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. READ MORE
