  1. 11. Miljöpåverkan av hund- och kattfoder ur ett livscykelperspektiv

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

    Författare :Louise Engsmyre; [2023]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : This study investigates the environmental impact from dog food and cat food produced in Sweden. With over 2.5 million dogs and cats in Sweden the potential environmental effect from their food is relevant to investigate. The aim of this study is therefore to quantify the environmental impact of 1 kg dog and cat food sold by Granngården. LÄS MER

  3. 12. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rebecca Nibelius; [2023]
    Nyckelord :Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

    Sammanfattning : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). LÄS MER

  4. 13. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elsa Muller; [2023]
    Nyckelord :Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Sammanfattning : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. LÄS MER

  5. 14. Challenges to using recycled High-density polyethylene materials for pipe manufacturing

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

    Författare :Lisa Erichs; [2023]
    Nyckelord :HDPE; Pressure pipe; Recycling; Properties; Earth and Environmental Sciences;

    Sammanfattning : Recycling has become increasingly relevant to solve environmental problems related to the enormous amount of plastic waste. Recycling plastic has many environmental benefits, but it is challenging to find applications where recycled plastic can provide the same functionality as virgin plastic. LÄS MER

  7. 15. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER
