  2. 21. Borehole heat store design optimization

    Author : Bo Nordell; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. READ MORE

  4. 22. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics

    Author : Annika Linkhorst; Sebastian Sobek; Frédéric Guérin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; climate; carbon cycle; lake; limnology; inland water;

    Abstract : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. READ MORE

  5. 23. Increasing the impact and sustainability of safe drinking water supply systems in rural Bangladesh : Randomized experiments with interventions in project life cycle

    Author : Md. Ahasan Habib; Prosun Bhattacharya; Anna Tompsett; Mushfiq Mobarak; KTH; []

    Abstract : Tillgång till rent dricksvatten är en global utmaning, vilket återspeglas i hållbar utvecklingsmål 6. I Bangladesh är det en brådskande fråga att överbrygga klyftan mellan de som har säkert hanterat dricksvatten och de med förbättrade källor. READ MORE

  6. 24. Life cycle assessment in the development of forest products : Contributions to improved methods and practices

    Author : Gustav Sandin; Magdalena Svanström; Greg Peters; Mats Westin; Annica Pilgård; Michael Narodoslawsky; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R D; LCA; Life cycle assessment; wood; forest product; forestry; impact assessment; scenario modelling; end-of-life modelling; allocation; multi-functional; planetary boundaries; life cycle inventory; life cycle impact assessment; environmental assessment;

    Abstract : The prospect of reducing environmental impacts is a key driver for the research and development (R&D) of new forest products. Life cycle assessment (LCA) is often used for assessing the environmental impact of such products, e.g. for the purpose of guiding R&D. READ MORE

  7. 25. Indicators for Measuring the Sustainability of Urban Water Systems - A Life Cycle Approach

    Author : Margareta Lundin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indicators; wastewater systems; LCA; decision-making; environmental systems analysis; sewage sludge; sustainable development; life cycle assessment; urban water systems;

    Abstract : Infrastructure for the provision of drinking water and the treatment of wastewater and stormwater, is essential for an urban society. In this project methods are developed which measure and assess the sustainability of urban water systems. READ MORE
