    Författare :Peter James Joyce; Anna Björklund; Hellweg Stefanie; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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.

  2. 2. Integrated Life Cycle Design - Applied to concrete multi-dwelling buildings

    Författare :Mats Öberg; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; livslängd; materialval; energianvändning; inomhusklimat; livscykelanalyser; livscykelkostnader; hållbar utveckling; Sustainable construction; Building construction; Service life design; Multiple Attribute Decision Analysis; Energy efficient buildings; Life Cycle Assessment; projektering; betongkonstruktioner; flerbostadshus; Byggnadsteknik; Integrated life cycle design; Life Cycle Costing;

    Sammanfattning : The objective of this work is to explore ways of enhancing the overall lifetime quality, including cost and environmental efficiency, of Swedish concrete multi-dwelling buildings. The building and its characteristics, as well as the procedures for whole life optimisation, are addressed. LÄS MER

  3. 3. Life cycle assessment and life cycle cost analysis of a single-family house

    Författare :Bojana Petrovic; Ola Eriksson; Marita Wallhagen; Xingxing Zhang; Åsa Wahlström; Högskolan i Gävle; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; carbon-dioxide equivalent emissions; global warming potential; primary energy use; life cycle assessment; life cycle cost; Byggnad; koldioxidekvivalenta utsläpp; global uppvärmningspotential; pri-märenergianvändning; livscykelbedömning; livscykelkostnad; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : The building industry is responsible for 35% of final energy use and 38% of CO2 emissions at a global level. The European Union aims to reduce CO2 emissions in the building industry by up to 90% by the year 2050. Therefore, it is important to consider the environmental impacts buildings have. LÄS MER

    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

  5. 5. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective

    Författare :Sylvia Haus; Johan Bergh; Bishnu Chandra Poudel; Krushna Mahapatra; Göran Berndes; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest residues; fossil fuel substitution; forest management; radiative forcing; land use change; climate change; bioenergy; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Byggteknik; Civil engineering;

    Sammanfattning : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. LÄS MER
