    Sammanfattning : The world’s drinking water sources are under growing pressure due to human activities, including infrastructure projects, agriculture, climate change, and the ever-increasing need for freshwater. Although there is a strong call to protect our source waters instead of increasing treatment efficiency at the drinking water treatment plant, the extent of protection measures is often hotly debated.

    Sammanfattning : Durable water repellent (DWR) finishes are applied to textiles to impart water and in some cases oil repellency. Water (and oil) repellency can be an important contribution to a textile’s performance, for comfort or for the protection of human lives under extreme conditions. LÄS MER

  7. 25. Environmental impact of ashes used in a landfill cover construction

    Författare :Igor Travar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : The landfilling ban for combustible waste in EU countries and the extended use of bio fuels in heat and electricity production will result in an increasing generation of incineration residues, such as fly ash and bottom ash. Instead of landfilling, ashes used as a construction material in, e.g. LÄS MER
