  1. 1. Livscykelanalys av avloppsreningsverk : En jämförande studie mellan MBR och aktivslammetoden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ella Heinonen; [2023]
    Nyckelord :Membrane bioreactor; Environmental Impacts; Construction; Sewage treatment; Membranbioreaktor; Aktivt slam; Miljöpåverkan; Vattenrening; Konstruktion;

    Sammanfattning : Avloppsreningsverk är en viktig del av vattnets kretslopp och skyddar mottagande miljö från föroreningar i avloppsvattnet. Det finns olika tekniker att rena avloppsvattnet på och denna studie jämför den potentiella miljöpåverkan från MBR och aktivslammetoden ur ett livscykelperspektiv. LÄS MER

  3. 2. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Christopher Grüner; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. LÄS MER

  4. 3. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sandu Seres; [2021]
    Nyckelord :Diesel; Stirling; Photovoltaic; impact category;

    Sammanfattning : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. LÄS MER

  5. 4. Towards a Climatology of Polar Stratospheric Cloudsbased on observation with the IRF lidar

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Oliver Willbrink; [2021]
    Nyckelord :;

    Sammanfattning : The effect that the Polar stratospheric clouds (PSCs) have on the destruction of ozone in the polar vortex is well known. The study of these clouds is therefore highly relevant and important. A tool that can be used to gather parameters needed to describe the PSC is a lidar (Light Detection and Ranging). LÄS MER

  7. 5. Integrating planetary boundaries into the life cycle assessment of electric vehicles : A case study on prioritising impact categories through environmental benchmarking in normalisation and weighting methods when assessing electric heavy-duty vehicles

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ida Pehrson; [2020]
    Nyckelord :Life Cycle Assessment; Heavy-Duty Vehicles; Electric Vehicle; Normalisation; Weighting; Planetary Boundaries; Livscykelanalys; tunga transporter; elektriska fordon; normalisering; viktning; planetära gränser;

    Sammanfattning : The transport sector is facing great challenges for achieving development within the Earth’s boundaries. Currently, LCA studies on heavy- and medium-duty vehicles have mainly assessed the ‘well-to-wheel’ stage and the impact category climate change. LÄS MER
