Stabilization of urban waste incineration ash and coal fly-ash

Proceedings First International Symposium on Environmentally Conscious Design and Inverse Manufacturing, 1999
A guarantee against the industrial waste disposal site has become so difficult that the treatment problem of waste assumed seriousness. Accordingly, a block plate was produced by use of a new cement hydration accelerator developed as a method for the solidification of incineration ash and coal fly-ash and the effective utilization of industrial waste ...

Leachate of fly ash derived from refuse incineration

Environmental Monitoring and Assessment, 1991
For highly urbanized cities where there is a scarcity of land available for landfilling, incineration of refuse is a feasible solution for solid waste disposal. After incineration, about 20% by weight of fly ash and other residues are produced and disposed of by landfill.

Heavy metals in MSW incineration fly ashes

Journal de Physique IV (Proceedings), 2003
Incineration is a common solution for dealing with the increasing amount of municipal solid waste (MSW). During the process, the heavy metals initially present in the waste go through several transformations, ending up in combustion products, such as fly ash.

Accelerated carbonation of municipal solid waste incineration fly ashes [PDF]

Waste Management, 2007
As a result of the EU Landfill Directive, the disposal of municipal solid waste incineration (MSWI) fly ash is restricted to only a few landfill sites in the UK. Alternative options for the management of fly ash, such as sintering, vitrification or stabilization/solidification, are either costly or not fully developed.

Properties of Solid Waste Incinerator Fly Ash

Journal of Geotechnical Engineering, 1989
Since the late 1950s solid waste incinerators have become widely used in the United States. The incineration of solid waste produces large quantities of bottom and fly ash, which has been disposed of primarily by landfilling. However, as landfills become undesirable other disposal methods are being sought.

Dehalogenation Potential of Municipal Waste Incineration Fly Ash

Environmental Science and Pollution Research, 2003
In the first part of this paper the main principles which control the dehalogenation of polychlorinated aromatic compounds on municipal waste incineration fly ash (MWI-FA) have been discussed and the model fly ash of similar dehalogenation activity has been proposed.

Combined glassification of EAF dust and incinerator fly ash

Chemosphere, 2003
Stainless steelmaking dust contains large amount of heavy metals, such as Cr and Ni. If these hazardous materials are not treated properly, they will cause detrimental secondary contamination. Preliminary study on recycling stainless steelmaking dust employed the thermal molten technology.

The catalytic gasification of carbon in incinerator fly ash

Carbon, 1993
Four fly ashes collected from electrostatic precipitators—three from municipal solid waste incinerators and one from a coal-fired power plant—were studied for their potential to catalyze carbon gasification reactions. A fixed-bed tubular reactor employing mixtures of oxygen and nitrogen was used to measure CO and CO2 evolved from native carbon in fly ...

Cytotoxicity of Incinerator Fly Ash on Alveolar Macrophages

Journal of Testing and Evaluation, 1987
Abstract Fly ash samples were collected from the electrostatic precipitator of a municipal incinerator in Hong Kong. The physical and chemical properties of fly ash particles of a diameter smaller than 10 μm were studied by a scanning electron microscope incorporated with an X-ray energy dispersive microanalyzer, atomic absorption ...

Reuse of incinerator bottom and fly ashes to obtain glassy materials

Journal of Hazardous Materials, 2008
Bottom and fly ashes coming from the urban wastes incineration represent a by-product nowadays landfilled. By mixing different amount of these residues with others inert materials, such as glass cullet and feldspar waste, two vitrifiable mixtures are tailored.
