  2. 1. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

    Author : Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

  5. 3. Systems Aspects of Increased Swedish Waste Incineration

    Author : Jenny Sahlin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

    Abstract : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. READ MORE

  6. 4. Assessing the future environmental impact of lignin-based and recycled carbon fibres in composites using life cycle assessment

    Author : Frida Hermansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; lignin; prospective; carbon fibres; environmental assessment; bio based; LCA;

    Abstract : Carbon fibre reinforced polymers (CFRPs) are composite materials that are gaining attention for their lightweighting and strengthening properties in a wide range of applications. However, using them instead of conventional materials (such as steel or other composites) does not automatically lead to a decrease in life cycle climate impact or energy use. READ MORE

  7. 5. Recycling and durability of PVC materials focusing on pre- and post-consumer wastes from building products

    Author : Nazdaneh Yarahmadi; SP – Sveriges Tekniska Forskningsinstitut *(2016-12-31) SP – Sveriges Tekniska Forskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated ageing; Activation energy; Annealing; Cables; Dehydrochlorination; Dismantling; DSC; Elongation at break; Emissions; Energy recovery; Flooring; Heat ageing; Lifetime; Orientation; Physical ageing; Plasticised PVC; Plasticiser depletion; Profiles; Recycling; Repeated extrusion; Residual stability; Rigid PVC; Sustainable building; Chlorination; Degradation; Durability; Mechanical properties; Plastic building materials; Plasticizers; Stabilizers agents ; Tensile properties; Molecular level; Polyvinyl chlorides;

    Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.
