  1. 1. Life Cycle Assessment and Decision Making: Theories and Practices

    Författare :Henrikke Baumann; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA practice; LCA methodology; LCA modelling; institutionalisation; LCA procedure; life cycle accounting; LCA; systems analysis; decision making;

    Sammanfattning : Life cycle assessment (LCA) has been in use to a varying extent since the late 1960s. The fact that LCA methodology needs further development is a frequently identified barrier to the further application of LCA. Consequently, the literature with suggestions for improving LCA methodology is extensive. LÄS MER

  3. 2. LCA of ICT solutions: environmental impacts and challenges of assessment

    Författare :Yevgeniya Arushanyan; Anna Björklund; Åsa Moberg; Chris Preist; KTH; []

    Sammanfattning : Information and communication technology (ICT) is playing an important role in modern society, contributing to economic growth and affecting society and people’s lifestyles. There are high expectations on ICT to contribute to sustainable development, e.g. through greenhouse gas emissions reductions. LÄS MER

  4. 3. Environmental Considerations in the Zero-waste Valorisation of Bauxite Residue : A Life Cycle Perspective

    Författare :Peter James Joyce; Anna Björklund; Hellweg Stefanie; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment LCA ; bauxite residue; waste valorisation; Naturally Occurring Radioactive Materials NORM ; Life Cycle Thinking; LCA software; Circular Economy; Livscykelanalys LCA ; bauxitrest; avfallsvalorisering; naturligt förekommande radioaktiva ämnen NORM ; livscykeltänkande; LCA-programvara; cirkulär ekonomi; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

  5. 4. Life Cycle Assessment (LCA) of Industrial Milk Production

    Författare :Merete Høgaas Eide; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dairy; cleaning; sustainability; packaging; LCA; Life Cycle Assessment; toxicity; milk;

    Sammanfattning : Life Cycle Assessment (LCA) was applied to milk production and processing in a study of the Norwegian dairy industry. This method, LCA, is used to assess the potential environmental impact of a material, product or service throughout its entire life cycle, from the extraction of the raw materials, the production process, and the user phase, to the final disposal.

  7. 5. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

    Författare :Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. LÄS MER
