  1. 1. Evaluation of in-situ technology performance and decision analysis by combining economic and environmental impact analysis for a case study

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Elham Tamadonyazdian; [2023]
    Nyckelord :Stabilization; Dredging; Solidification; Cement mixtures; Binders; In-situ technology; Environmental impact categories; Life cycle assessment LCA ; Economic analysis; Life cycle costing LCC ; Global Warming Potential GWP ; Acidification Potential AP ; Eutrophication Potential EP ; Ozone Layer Depletion Potential ODP ; Single-Point Rate SPR .; Technology and Engineering;

    Sammanfattning : In the contemporary global context, the global focus on reducing environmental impacts in any formats has intensified. This study intends to assess the environmental impacts and life cycle costs associated with the A1-A5 stages (production and construction stages) of the Köping Port project and eight additional proposed scenarios.

  3. 2. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Sandberg; [2023]
    Nyckelord :Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Sammanfattning : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. LÄS MER

  4. 3. Stabilisering av flotte avsedd för muddring av fibersediment längs Sveriges östkust

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Erik Ljungberg; [2022]
    Nyckelord :Dredging; Fibre fiber deposits; Stabilization; SWATH; Fiberbank; Muddring; Stabilisering; SWATH;

    Sammanfattning : Sverige har en stor miljöskuld i form av fiberbankar fulla med miljöfarliga restprodukter från den pappers- och massaindustri som har definierat stora delar av svensk industri. Stora delar av östkusten samt flertalet sjöar fortsätter påverkas av dessa fiberbankar som kontinuerligt släpper ut miljögifter allt eftersom de eroderas av vågor eller då det organiska materialet bryts ned.

  5. 4. “Holding course” towards environmental injustice. An explorative analysis of the environmental injustices in the decision-making process of the 9th dredging of the Elbe River in Hamburg, Germany

    Master-uppsats, Lunds universitet/LUCSUS

    Författare :Dana Dedeck; [2022]
    Nyckelord :Sustainability Science; Dredging; Environmental Justice; Hamburg; Science Technology Studies; Port City; Social Sciences;

    Sammanfattning : Responding to the pressure of economies of scale, port cities like Hamburg “hold course” towards a development strategy, meeting demands of upscaling navigational infrastructure through dredging. Research focusing beyond distributional injustices is scarce and remains technocratically driven. LÄS MER

  7. 5. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Patrik Dahlström; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER
