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

    University essay from Lunds universitet/Matematisk statistik

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

    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

  3. 7. Plastic ingestion and diet composition in two common fish species from the Swedish Skagerrak

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Danja Fritscher; [2019]
    Keywords : microplastic; plastic ingestion; whiting; dab; diet composition; enzymatic tissue digestion;

    Abstract : Plastic ingestion is supposed to be linked to the feeding behaviour of the fish. Anthropogenic particles were expected to be accidentally ingested by the common dab due to its feeding strategy, which is focused on ground-living organisms. READ MORE
