  1. 1. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Författare :Gregory Makusa; Kauko Kujala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER

  3. 2. Mercury immobilization : a requirement for permanent disposal of mercury waste in Sweden

    Författare :Margareta Svensson; Bert Allard; Anders Düker; Björn Öhlander; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mercury; mercury sulphide; cinnabar; stabilization; solidification; encapsulation; monolith leaching; solubility; mercury speciation; diffusion; apparent diffusion coefficient; Chemistry; Kemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The Swedish Government states that mercury in the Swedish industry and private use shall be collected and waste containing more than 1% of mercury shall be conditioned for permanent storage in proposed groundwater-saturated repository in deep bedrock. The owners of mercury waste in Sweden are responsible for finding ways to the conversion of the mercury waste to insoluble forms. LÄS MER

  4. 3. Distribution and chemical association of trace elements in incinerator residues and mining waste from a leaching perspective

    Författare :Naeem Saqib; Mattias Bäckström; Stefan Karlsson; William Mayes; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trace elements; partitioning; fly ash; bottom ash; speciation; association; risk assessment; wood waste; incineration; mining waste; Chemistry; Kemi;

    Sammanfattning : Incineration is a mainstream strategy for solid waste management in Sweden and all over the world. Improved knowledge and understanding about the distribution of trace elements (in ashes) during incineration, and how trace element partitioning respond to the changes in waste composition, are important in terms of combustion process optimization and plant efficiency.

  5. 4. Mechanical properties of stabilized dredged sediments : for sustainable geotechnical structures

    Författare :Gregory Paul Makusa; Göran Holm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER

  7. 5. Stabilization remediation of soils contaminated with per- and polyfluoroalkyl substances (PFASs)

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

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a major global concern in pollution of drinking water sources and aquatic environments. Due to the high persistence and mobility of these compounds, remediation methods for PFAS-contaminated soils are urgently needed to protect the surrounding environment and drinking water source areas.
