  1. 21. Groundwater resources in hard rock coastal terrains : Insights into heterogeneity and spatial variability

    Författare :Robert Earon; Bo Olofsson; Okke Batelaan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Crystalline Rock; Groundwater Balance; Kinematic porosity; Groundwater Recharge; Water Security; Coastal Aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. LÄS MER

  2. 22. Contaminants of Emerging Concern in Swedish Freshwater Environments: Sources, Occurrence, and Impacts

    Författare :Daniel Malnes; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Contaminants of emerging concern (CECs) is one of several reasons for the deterioration of surface water quality globally, even though the CECs occur in trace concentrations. This thesis produced new CEC data through a oneyear field study for substances which occur in Sweden’s three largest lakes and their associated rivers. LÄS MER

  3. 23. Resource recovery from wastewater treatment: challenges, opportunities and guidance for planning and implementation

    Författare :Mariana Cardoso Chrispim; Miklas Scholz; Marcelo Antunes Nolasco; Jennifer R. McConville; Avdelningen för Teknisk vattenresurslära; []

    Sammanfattning : Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. LÄS MER

  4. 24. Taking stock of large-scale lithium-ion battery production using life cycle assessment

    Författare :Mudit Chordia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brine; Spodumene; Lithium-ion battery; Lithium; Life cycle assessment; Giga-factory; Upscaling;

    Sammanfattning : Battery electric vehicles are being increasingly favored as an alternative to internal combustion engine vehicles (ICEVs). This is mainly due to their lower environmental impact when compared to ICEVs over the vehicle’s lifetime. LÄS MER

  5. 25. Strengthening the Environmental Sustainability of Production Systems through Digitalization

    Författare :Xiaoxia Chen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital technology; Industry 4.0; digitalization; manufacturing; mechanisms; environmental sustainability; production system; environmental benefits;

    Sammanfattning : Industrial companies are facing incremental pressure to strive for environmentally sustainable development. This can be attributed to their increased contribution to energy consumption and carbon emissions and the growing international attention focused on global warming. LÄS MER
