  1. 1. Material Flows Incurred by Activities at Project Sites

    Author : Nina Modig; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary organization; project site; project; supply network; logistics; material flows;

    Abstract : The execution of numerous projects is dependent on the movement of large quantities of heterogeneous material to and from project sites. This has to be done in a timely manner to successfully produce desired outputs, e.g. buildings, concerts, peacekeeping operations and sport events. READ MORE

  2. 2. A Study on Particle Motion and Deposition Rate Application in Steel Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Peiyuan Ni; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

  3. 3. Managing the flows? Furthering a socio-material flow methodology for industrial ecology

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Mathias Lindkvist; [2019]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life cycle assessment LCA ; industrial ecology; conceptualisation; action nets; field studies; actor-network-theory ANT ; material flow; socio-material; methodology; review;

    Abstract : This dissertation defends the thesis that application of the socio-material methodology that I present can assist environmentally more effective decision-making. The methodology provides a recipe for a systematic and accurate understanding of how human actions determine environmental impacts via material (tangible) flows. READ MORE

  4. 4. Interest in Material Cycle Closure? Exploring Evolution of Industry's Responses to High-grade Recycling from an Industrial Ecology Perspective

    University dissertation from The International Institute for Industrial Environmental Economics

    Author : Philip Peck; Lunds universitet.; Lund University.; [2003]

    Abstract : Popular Abstract in Swedish Många material som ingår i tillverkade varor har kvar sina kvaliteter även när varorna är uttjänta. Men bara en liten del av dessa material återvinns idag på ett sätt som gör det möjligt att återanvända materialet för samma syfte och med bevarade egenskaper. READ MORE

  5. 5. Natural resources and sustainable energy Growth rates and resource flows for low-carbon systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Simon Davidsson; Uppsala universitet.; [2016]
    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.
