  1. 1. Characterisation of organic materials from incineration residues

    Författare :Inger Johansson; Anna Ledin; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ash; biofuel; waste; residues; MSWI; incineration; leaching; organic carbon; organic acids; polycyclic aromatic hydrocarbons; PAH; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : The organic material present in incineration residues has been examined. Water leachable organic material was characterised and classified into hydrophilic and hydrophobic acids, neutrals and bases. Changes of the organic material during weathering were followed. LÄS MER

  3. 2. Characterisation of residues : Release of contaminants from slags and ashes

    Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER

  4. 3. Waste incineration residues : Persistent organic pollutants in flue gas and fly ash from waste incineration

    Författare :Eva Weidemann; Lisa Lundin; Stellan Marklund; Jean-Francois Boily; Henrik Bristav; Kees Olie; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSW; PCDD; PCDF; PCN; PCB; POP; formation; degradation; case study; flue gas sampling thermal treatment; fly ash; surface characterization;

    Sammanfattning : Modern societies produce large quantities of municipal solid waste (MSW), which is commonly disposed of by incineration. This has several advantages: it reduces the waste’s volume and sterilizes it while also enabling energy recovery. LÄS MER

  5. 4. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

    Författare :Gustav Häggström; Marcus Öhman; Anders Lagerkvist; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sewage sludge; agricultural residues; forest residues; ash transformation; potassium; phosphorus; combustion; gasification; phosphorus recovery; Energy Engineering; Energiteknik;

    Sammanfattning : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. LÄS MER

  7. 5. Mechanical Properties of Residues as Unbound Road Materials - experimental tests on MSWI bottom ash, crushed concrete and blast furnace slag

    Författare :Maria Arm; KTH; []
    Nyckelord :residues; unbound materials; MSWI bottom ash; crushedconcrete; blast furnace slag; mechanical properties;

    Sammanfattning : For recycled aggregates and industrial by-products to beused correctly in road construction, it is necessary to knowtheir properties. Existing material specifications and testmethods for aggregates used in Sweden and in many othercountries are indirect and are based on empiricism. LÄS MER
