  1. 1. Assessment of tools for environmentally preferable procurement with a life cycle perspective : the case of acquisition in Swedish defence

    Författare :Elisabeth Hochschorner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Acquisition; Ecodesign tools; Life Cycle Assessment; LCA; MECO; Public procurement; Simplified; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Procurement in public and non-public organisations has the potential to influence product development towards more environmentally preferable products. In 2003, public procurement in Sweden was 28% of GDP. Different types of approaches can contribute some knowledge and thereby facilitate the choice of environmentally preferable products. LÄS MER

  3. 2. Simplifying LCA use in the life cycle of residential buildings in Sweden

    Författare :Sjouke Beemsterboer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle assessment LCA ; Simplified LCA; building construction; multifamily residential building; Life Cycle Management LCM ;

    Sammanfattning : This thesis discusses the use of environmental life cycle assessment (LCA) in the building life cycle. While the life cycle of a residential building is an important source of environmental concern, knowledge about LCA remains scarce and sporadic in most construction companies. LÄS MER

  4. 3. 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

  5. 4. Simplified Life Cycle Assessment Approaches and Potential Impact Shifts

    Författare :Katja Tasala Gradin; Sofia Ritzén; Anna Hedlund-Åström; Matthias Finkbeiner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA simplification approach; impact shift; reduction measures; road transport; streamlining; screening; Machine Design; Maskinkonstruktion;

    Sammanfattning : Road transport contributes to approximately one quarter of all EU greenhouse gas emissions and is the leading cause of air pollution in cities. There are significant measures aimed at the reduction of use phase environmental impacts; in the EU, these strategies focus on the decarbonisation of road transport, such as through the prioritization of low- and zero-emission vehicles.

  7. 5. Life cycle assessment of renewable-based hydrocarbon plastics

    Författare :Christin Liptow; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; renewable LDPE; biomass-based plastics; simplified LCA for conventional; LCA and process simulation;

    Sammanfattning : Plastics are an important commodity of our daily life. And although their majority is still based on fossil feedstocks, numerous efforts are made to stem the environmental consequences related to their production. One approach is the use of renewable materials (biomass) to produce today’s conventional plastics. LÄS MER
