  1. 1. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

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

    Författare :Lakshay Vashist; [2023]
    Nyckelord :Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

    Sammanfattning : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. LÄS MER

  3. 2. 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

  4. 3. Täckmaterial i växthus

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

    Författare :Alva Tangfelt; [2022]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : Grobruket is a small company that works with cultivation in many ways and they are very aware of their climate footprint. Therefore, they are also interested in taking a deeper look into the environmental impact of different covering materials used for greenhouses. LÄS MER

  5. 4. Evaluation of transition towards zero emission commuter ferries : Comparative Analysis of Fuel-based and Battery-based Marine Propulsion System from financial and environmental perspectives

    Master-uppsats, KTH/Marina system

    Författare :Varun Goel; Sonja Wadelius; [2021]
    Nyckelord :Water-borne public transport; Maritime industry; marine propulsion system; marine Li-ion batteries; diesel-electric; diesel-mechanical; all-electric; life cycle assessment; cost assessment.; Vattenburenkollektivtrafik; marinaindustrin; marinaframdrivningssystem; marinabatterisystem; dieselelektrisk; diesel mekanisk; helt elektrisk; livscykelanalys; kostnadsanalys.;

    Sammanfattning : The purpose of this study is to compare the life-cycle cost and environmental impact of the existing fuel-based propulsion system, on public commuter ferries in Stockholm, with a battery based propulsion system. The study is divided into multiple layers. 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
