  1. 1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  3. 2. Varnishing of Fiber-based Closures

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nisha Sunil David; [2023]
    Nyckelord :Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Sammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER

  4. 3. Microplastics in Scanian wetlands : Sege river & Kävlinge river

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Ludvig Stoltz; Pernilla Leijon; [2023]
    Nyckelord :plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

    Sammanfattning : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. LÄS MER

  5. 4. From Ocean to Table: Microplastic contamination in Nordic salts

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Anna Nyika; [2023]
    Nyckelord :Microplastic MP ; MP pollution; plastic pollution; sea salt; rock salt; Nordics; Iceland; Denmark; plastic waste management; human health; marine environment.; Earth and Environmental Sciences;

    Sammanfattning : Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. LÄS MER

  7. 5. Havet, plasten och ansvaret

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska fakulteten; Lunds universitet/Juridiska institutionen

    Författare :Ulrika Malmberg; [2023]
    Nyckelord :Environmental law; miljörätt; Law and Political Science;

    Sammanfattning : This thesis concludes that the common but differentiated responsibility principle is applied with the best results of the global responsibility to clean up the high sea from plastic pollution. The principle confirms that there is a historical responsibility for the plastic pollution that exists still today but has been in the ocean for decades. LÄS MER
