  3. 2. Research of alternative methods of marine litter collection : Study of marine plastic pollution

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ciaran Conway; Aydar Gaynullin; [2022]
    Nyckelord :;

    Sammanfattning : The discovery of plastic and its unique qualities created a great opportunity for manufacturing and an improved quality of life. The annual production of plastic is 368 million tonnes, this number is continuously increasing as nowadays almost every product has a plastic component in it. However, this improvement in lifestyle comes at a cost. LÄS MER

  4. 3. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Emma Overgaard; [2021]
    Nyckelord :IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

    Sammanfattning : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. LÄS MER

  5. 4. PlaCo : The plastic collecting robot

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Annie Persson; Johanna Bergsten; [2021]
    Nyckelord :Arduino; IR-sensor; marine debris; mechatronics; microplastics; ultrasonic sensor; Arduino; IR-sensor; marin nedskräpning; mekatronik; mikroplaster; ultraljudssensor;

    Sammanfattning : The oceans are an essential global resource for all living organisms but especially for us humans. However, year after year we continue to neglect proper recycling of our waste, resulting in litter ending up in our oceans. The majority of said litter comes from single use plastic items. LÄS MER

  7. 5. Characterization of microplastics in storm water in Örebro, Sweden

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Isabelle Karlsson Sjögren; [2020]
    Nyckelord :Chemical characterization; microplastic; pollution; storm water; visual characterization;

    Sammanfattning : Microplastic is a widespread pollutant in marine and fresh water systems. A major pathway by which microplastics end up in these systems is via storm water. Storm water is generated as precipitation drain off of impenetrable surfaces like paving. LÄS MER
