  3. 2. Assessing design strategies for improved life cycle environmental performance of vehicles

    Författare :Sofia Poulikidou; Anna Björklund; Per Wennhage; Gregory Keoleian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle design; Design strategies; Lightweight design; Electric vehicles; Design for Environment DfE ; DfE tools; Life cycle assessment LCA ; Simplified LCA; Composite materials; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. LÄS MER

  4. 3. Resource efficient products in a circular economy – The case of consumables. From environmental and resource assessment to design guidelines

    Författare :Siri Willskytt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; product characteristics; circular product design; resource efficiency; LCA; consumable products; ecodesign; design guidelines; circular economy;

    Sammanfattning : The circular economy (CE) is a concept to challenge the unsustainable production, consumption, and waste management of products, through the recirculation of resources and products through various means while reducing environmental impact. Within this concept, many measures are recommended for reducing environmental impact and resource use. LÄS MER

  5. 4. Lifecycle of Black Carbon in the Arctic

    Författare :Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []

    Sammanfattning : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. LÄS MER

  7. 5. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

    Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

    Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.
