  1. 1. The Karma of Products : Exploring the Causality of Environmental Pressure with Causal Loop Diagram and Environmental Footprint

    Författare :Rafael Laurenti; Björn Frostell; Andrius Plepys; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Products; Environmental Pressure; Causal Loop Diagram; Environmental Footprint; Industrial Ecology; Industriell ekologi;

    Sammanfattning : Environmental pressures from consumer products and mechanisms of predetermination were examined in this thesis using causal loop diagram (CLD) and life cycle assessment (LCA) footprinting to respectively illustrate and provide some indicators about these mechanisms. Theoretical arguments and their practical implications were subjected to qualitative and quantitative analysis, using secondary and primary data. LÄS MER

  3. 2. Towards sustainable shipping: Evaluating the environmental impact of electrofuels

    Författare :Elin Malmgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental assessment; LCA; emerging technology; marine fuels; human health; future fuel; sustainable shipping; carbon utilization; power-to-x; carbon capture;

    Sammanfattning : The global, local, and regional environment is under pressure from human activity. Changes in the environment can be beneficial and strived for, but environmental and health problems need to be considered when we design human activities. LÄS MER

  4. 3. "Under pressure" : interaction between pharmaceuticals and river bacteria

    Författare :Aleksandra Hagberg; Madeleine Ramstedt; Mette Burmølle; Jerker Fick; Rikke Louise Meyer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biofilms; river bacteria; pharmaceutical contamination;

    Sammanfattning : Pharmaceuticals are often entering the environment without being completely decomposed. Once released in the environment they continue to carry on their main function but instead targeting the inhabitants of the aquatic ecosystem. Our interest was drawn towards the bacteria, that are often present in the environment in the form of biofilms. LÄS MER

  5. 4. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

    Författare :Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. LÄS MER

  7. 5. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture

    Författare :Elin Malmgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; liquefied natural gas; power-to-X; methanol; power-to-gas; carbon capture and utilization; thematic analysis; Marine renewable energy; onboard carbon capture; marine fuels; LCA; shipping; electrofuels;

    Sammanfattning : The global, local, and regional environment is under pressure from human activity. Shipping is a human activity causing emissions to air, water, and soil, which has direct and indirect effects on the environment. LÄS MER
