  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Safana Al-Ashor; [2024]
    Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

  3. 2. 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. 3. Polyhydroxyalkanoate Production from Municipal Waste Streams

    University essay from KTH/Resursåtervinning

    Author : Elsa Eriksson; [2020]
    Keywords : Polyhydroxyalkanoate; volatile fatty acids; mixed culture; bioreactor; municipal waste streams; Polyhydroxialkanoat; flyktiga fettsyror; blandad kultur; bioreaktor; kommunalt avfall;

    Abstract : Polyhydroxyalkanoates (PHAs) are a group of bioplastics, which are produced through microorganisms. They are accumulated in granules inside bacteria’s cell cytoplasm and serve as an energy reserve. READ MORE

  5. 4. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

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

    Author : Giulia Elli; [2019]
    Keywords : PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Abstract : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. READ MORE

  6. 5. Evaluation of the biopolymer Poly-hydroxi-alkanoates

    University essay from Lunds universitet/Förpackningslogistik

    Author : Helena Lindh; [2005]
    Keywords : bio; polmer; Poly-hydroxi-alkanoates; Technological sciences; Teknik; Technology and Engineering;

    Abstract : Biopolymers are interesting materials from a sustainable point of view. Especially since consumers increasingly demand environmental friendly packages as well as more convenient packages with easy open and close features on the packages. The demands for convenient packages lead to more and more plastics in the packaging industry. READ MORE
