  1. 11. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Marc Jirström; [2021]
    Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

    Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE

  3. 12. 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

  4. 13. The biodegradable straw - Investigating how enzymes can be used to enhance desired product qualities of drinking devices.

    University essay from Lunds universitet/Innovation

    Author : Charlotte Parnefjord Gustafsson; Hanna Liang; [2020]
    Keywords : biodegradable; bioplastics; drinking devices; enzymes; fibre material; PHA; product design; statistical analysis; straws; Technology and Engineering;

    Abstract : The increasing production of single-use plastics negatively affects the climate. The resulting plastic ocean debris has fatal consequences to marine life. As a result, the European Parliament has placed a ban on single-use plastics by 2021, making it essential to study sustainable materials for single-use products such as straws. READ MORE

  6. 15. Environmental issues from sugarcane plantations in Brazil and how to handle them with market-based instruments

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Freja Milton; [2019]
    Keywords : Market-based instruments; environmental offsets; Payments for ecosystem services; PES; Brazil; bioplastic; biopolymer; sugarcane; certification; environmental impacts from sugarcane cultivations.; Earth and Environmental Sciences;

    Abstract : This study is a literature review of three market-based instruments used for land management; environmental offsets, payments for ecosystem services (PES) and certification, and how they could be used to mitigate environmental impacts from sugarcane cultivation in Brazil when purchasing biopolymers. The study showed that certification is the most common market-based instrument in Brazil. READ MORE
