  1. 1. Life Cycle Assessment of a small scale, solar driven HVR water purification system

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

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  3. 2. Life Cycle Assessment of a 3D printer : A comparative and attributional life cycle assessment of 3D printer

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

    Författare :Rishi Akash Chinnakonda Senthil; [2022]
    Nyckelord :3D printer; LCA; impact categories;

    Sammanfattning : Three-dimensional (3D) bio printing offers a wide range of applications, including the placement, design, and patterning of biological components such as living cells, nucleic acids, tissues, and many more. Bioprinting has seen great growth and breakthroughs in recent years, particularly in 3D printing. 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. 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

  7. 5. Life cycle analysis on phase change materials for thermal energy storage.

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

    Författare :Elin Johansson; Filip Norrman; [2019]
    Nyckelord :;

    Sammanfattning : Sustainable energy sources and utilization is a large area of interest and the developments are moving fast. Recently, thermal energy storage in the form of phase change materials other than water have caught more interest and a need of analysis for the entire life cycle of the materials have appeared.
