  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Efficiency of synthetic vision in simple scenarios

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Richard Palm; Håvard Woie Alstadheim; [2022]
    Nyckelord :;

    Sammanfattning : Modern crowd simulation models can display a range of different properties, such as realism, efficiency, or emergent self-organizing patterns. These properties often vary by the specific situation that the model is used in. A model can be realistic when used in one scenario and break down completely in another scenario. LÄS MER

  5. 4. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Melinda Rydberg; [2022]
    Nyckelord :Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Sammanfattning : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.
