  1. 26. Strategic Assessment of Drinking Water Production Systems Environmental impacts from a Life cycle perspective : A case study of Norrvatten future drinking water production alternatives

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rahul Aggarwal; [2020]
    Keywords : Life cycle assessment LCA ; Drinking water treatment; Environmental impacts; Sustainability; Global warming; Nanofiltration; Conventional water treatment; Ultrafiltration; Expansion alternatives; Water Quality; Water treatment plant; Environmental optimization; Drinking water quality;

    Abstract : Climate change is a global challenge that requires proactive action from municipalities, companies, and other organizations to prioritize sustainability in their daily operations. In the past few decades, life cycle assessment (LCA) approach has been successfully applied for environmental assessments in the drinking water sector. READ MORE

  3. 27. Simulation of air quality in underground train stations

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Benjamin Söderberg; [2020]
    Keywords : PM10; aerosols; air pollution; particulate matter; emission factors; underground train station; PM10; luftkvalité; tåg; emissionsfaktorer; underjordiska tågstationer;

    Abstract : Particulate matter (PM) is a widespread air pollutant of microscopic particles that are suspended in the atmosphere. There is high concentration of PM in underground train stations and tunnels. The concentration of particulate matter (PM10) measured in Stockholm’s metro varies significantly between day and nighttime traffic of trains. READ MORE

  4. 28. 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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  5. 29. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Ellen Carneheim; [2020]
    Keywords : Physics and Astronomy;

    Abstract : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... READ MORE

  6. 30. WRF-Chem vs machine learning approach to predict air quality in urban complex terrains: a comparative study

    University essay from Högskolan Dalarna/Mikrodataanalys

    Author : Andrey Kudryashov; [2020]
    Keywords : Machine learning; WRF-Chem; comparative study; air quality;

    Abstract : Air pollution is the main environmental health issues that affects all the regions and causes millions premature deaths every year. In order to take any preventive measures, we need the ability to predict pollution level and air quality. This task is conventionally solved using deterministic models. READ MORE
