  3. 2. Environmental Life-cycle Assessment in Microelectronics Packaging

    Författare :Anders Andrae; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; microelectronics packaging; data collection; attributional environmental life-cycle assessment; uncertainty analysis; upstream processes; consequential life-cycle assessment; environmental life-cycle inventory; microelectronic products;

    Sammanfattning : An increased understanding of the application of environmental Life-Cycle Assessment (LCA) methodologies in the microelectronics packaging area should help in developing environmentally sound product systems. The aim of the present thesis is to increase the knowledge of using LCA tools, methods and models, in application to current and new microelectronic products. LÄS MER

  4. 3. Towards inclusion of Biodiversity in Life Cycle Assessment

    Författare :Emke Vrasdonk; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Impact assessment; Biodiversity; LCA; eDNA; Life Cycle Assessment; Sustainability; Reference situation; Land Use; Biodiversity conservation; Metabarcoding; Indicators;

    Sammanfattning : Biodiversity- crucial for ecosystem health and its products and services – is being lost at an alarming rate. While it is clear that human consumption is the main driving force of the considerable losses, conversion of natural habitats for production is continuing and the subsequent intensification of those systems is likely to cause even further biodiversity decay.

  5. 4. Life Cycle Assessment of Present and Future Marine Fuels

    Författare :Selma Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

    Sammanfattning : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

  7. 5. Life-Cycle Considerations for Environmental Management of the Swedish Railway Infrastructure

    Författare :Niclas Svensson; Mats Eklund; Tomas Kåberger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enviornmental management; railways; life cycle perspective; environmental pressures; material use; Miljöledning; järnvägar; livscykelperspektiv; miljöpåverkan; materialhantering; Environmental engineering; Miljöteknik;

    Sammanfattning : Syftet med den här avhandlingen är att förbättra möjligheter till miljöledning av järnvägens infrastruktur genom att utveckla en metod för att rikta in ansträngningar på att minska miljöpåverkan från infrastrukturens produkter. Metodens används i ett byggprojekt och dess robusthet blir testad. LÄS MER
