  2. 1. Unsaturated Phase Environmental Processes in MSWI Bottom Ash

    Author : Aamir Ilyas; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bottom Ash; Frequency Domain; Hydrogen Recovery; Leaching; Microbial Respiration; Eco-toxicity; Solid Waste;

    Abstract : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. READ MORE

  4. 2. Characterisation of organic materials from incineration residues

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

    Abstract : 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. READ MORE

  5. 3. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions

    Author : Susanna Olsson; Jon Petter Gustafsson; Dan Berggren; Erik Kärrman; Bo Bergbäck; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; Environmental chemistry; Miljökemi;

    Abstract : There are several incentives for using bottom ash from municipal solid waste incineration (MSWI bottom ash) as a construction material, such as for road construction. These incentives include decreased disposal of material on landfills and a reduced amount of raw material extracted for road building purposes. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Environmental assessment of incinerator residue utilisation

    Author : Susanna Toller; Jon Petter Gustafsson; Dan Berggren Kleja; Erik Kärrman; Thomas H. Christensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MSWI bottom ash; wood ash; recycling; LCA; environmental assessment; geochemical speciation modelling; dissolved organic matter; copper Cu ; Environmental engineering; Miljöteknik;

    Abstract :  In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. READ MORE
