  1. 1. Chemical Properties of FBC Ashes

    University dissertation from Chalmers University of Technology

    Author : Britt-Marie Steenari; Chalmers tekniska högskola.; Chalmers University of Technology.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; Environmental engineering; ash chemistry; ash hydration reactions; ash leaching; ash melting; CaS; deposits; environmental impact of ash handling; FBC; PFBC; forest fertiliser; fouling; fuel additives; plant nutrient recycling; sintering; straw ash; wood ash characteristics; wood ash recycling;

    Abstract : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. READ MORE

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

    University dissertation from Media Tryck

    Author : Aamir Ilyas; Lunds universitet.; Lund University.; [2013]
    Keywords : Frequency Domain; Bottom Ash; Hydrogen Recovery; Leaching; Microbial Respiration; Eco-toxicity; Solid Waste; TEKNIKVETENSKAP; TECHNOLOGY;

    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

  3. 3. Ecotoxicological classification of ash materials

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Sara Stiernström; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ecotoxicity; ash; classification; leaching; Waste Framework Directive; CLP-Regulation; Hazard Identification; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Susanna Olsson; KTH.; [2005]
    Keywords : bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi 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

  5. 5. Environmental assessment of incinerator residue utilisation

    University dissertation from Stockholm : KTH

    Author : Susanna Toller; KTH.; [2008]
    Keywords : MSWI bottom ash; wood ash; recycling; LCA; environmental assessment; geochemical speciation modelling; dissolved organic matter; copper Cu ; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper 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
