    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

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Peter James Joyce; KTH.; [2018]
    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.

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

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Diego Peñaloza; KTH.; [2017]
    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; Civil and Architectural Engineering; Byggvetenskap;

    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

  5. 5. Exploring the relevance of uncertainty in the life cycle assessment of forest products

    Detta är en avhandling från Umeå : Umeå University

    Författare :Frida Røyne; Umeå universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; wood; forestry; uncertainty; biorefinery; industrial symbiosis; allocation; system boundaries; bio-economy; LCA; trä; skogsbruk; osäkerhet; bioraffinaderi; industriell symbios; allokering; systemgränser; bioekonomi;

    Sammanfattning : The role of forest biomass as a replacement for fossil fuels and products is becoming increasingly prominent as a means to mitigate climate change. To guide a sustainable transition towards a forest-based bio-economy, it is important that advantages and disadvantages of forest products are assessed, to ensure that the products deliver environmental impact reduction.
