  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. Evaluation of novel climate-friendly feed for Nile tilapia in Tanzania

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Vilma Johansson; [2023]
    Nyckelord :Black soldier fly; novel fish feed; circular aquaculture; sub-Sahara aquaculture; greenhouse gas emissions; LCA; Nile tilapia;

    Sammanfattning : Tanzania is a country located in sub-Sahara Africa by the Indian Ocean. Tanzania's aquaculture sector is small but has the potential to grow. As the population grows, so does the demand for food. Nile tilapia is the most cultured fish in Tanzania due to its hardiness, fast growth and tolerance to many environmental conditions. LÄS MER

  4. 3. The potential use of black soldier fly larvae residue as a fertilizer

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :An-Marthe Ingelaere; [2023]
    Nyckelord :organic waste; fertilizer; black soldier fly; residue; physico-chemical characteristics; sub-Saharan Africa; socio-economic constraints;

    Sammanfattning : In sub-Saharan Africa (SSA), the primary constraint of agriculture productivity has consistently been ascribed to soil fertility. A common approach to improve soil fertility is the use of fertilizers, both organic and inorganic. Though recently interest is increasing in the use of newer alternatives like biostimulants. LÄS MER

  5. 4. Husdjurens roll för att uppfylla FN:s hållbarhetsmål

    Kandidat-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Amanda Algotson; [2023]
    Nyckelord :Agenda 2030; globala hållbarhetsmålen; husdjur; djurvälfärd; nötkreatur; gris; fjäderfä; akvakultur;

    Sammanfattning : År 2015 beslöt FN om 17 hållbarhetsmål som ingår i Agenda 2030. De finns för att världen ska bli fri från hunger och fattigdom, för att samhället ska bli mer jämställt och för att skydda miljön. LÄS MER

  7. 5. The foraging distribution of Cape gannets in relation to Addo Elephant National Park Marine Protected Area

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Pelagia Maria Tsousi; [2023]
    Nyckelord :cape gannets; morus capensis; marine Protected Areas; addo Elephant National Park Marine Protected Area; foraging distribution;

    Sammanfattning : Seabirds are considered to be the sentinels of the ocean, as they are able to locate their prey in spite of the great heterogeneity of the marine environment. During the breeding season, these central-place foragers not only need to find prey to maintain themselves but also to feed their young. LÄS MER
