Vitrification of municipal solid waste incineration fly ash with B2O3 as a fluxing agent

Waste Management, 2020
In this paper, B2O3 was used as a fluxing agent to reduce the melting temperature of municipal solid waste incineration (MSWI) fly ash and promote the glassy phase formation. Ash fusion temperature (AFT) test, atomic absorption spectroscopy (AAS), X-ray diffraction(XRD), scanning electron microscope (SEM) and thermodynamic calculation were carried out.

The cement solidification of municipal solid waste incineration fly ash

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2006
The chemical composition, the content and the leachability of heavy metals in municipal solid waste incineration (MSWI) fly ash were tested and analyzed. It is shown that the leachability of Pb and Cr exceeds the leaching toxicity standard, and so the MSWI fly ash is considered as hazardous waste and must be solidified.

Hydrothermal solidification of municipal solid waste incineration fly ash

Research on Chemical Intermediates, 2011
Hydrothermal solidification of municipal solid waste incineration (MSWI) fly ash has been conducted under saturated steam pressure at 200 °C for up to 48 h with quartz addition. To enhance the strength of solidified specimens further, the raw fly ash was pre-treated by water-washing and mixed with NaOH solution (2 M) as reaction solvent.

Vitrification of municipal solid waste incineration fly ash using biomass ash as additives

Environmental Technology, 2014
Thermal melting is an energy-costing solution for stabilizing toxic fly ash discharged from the air pollution control system in the municipal solid waste incineration (MSWI) plant. In this paper, two different types of biomass ashes are used as additives to co-melt with the MSWI fly ash for reducing the melting temperature and energy cost.

Melting of municipal solid waste incinerator fly ash by waste-derived thermite reaction

Journal of Hazardous Materials, 2009
This work describes a novel approach for melting municipal solid waste incinerator (MSWI) fly ash, based on self-propagating reactions, by using energy-efficient simulated waste-derived thermite. The self-propagating characteristics, the properties of the recycled alloy and slag and the partitioning of heavy metals during the process are also studied ...

Recovery of Zinc from Municipal Solid Waste Incineration Fly Ash

Science of Advanced Materials, 2021
In recent years, over one million tons of Municipal Solid Waste (MSW) incineration fly ash has been generated annually Taiwan. Only a small percentage of the ash was used as raw material for other utilities besides landfill. Fly ash contains many harmful heavy metals, such as Cd and Cr, among others; however, fly ash also contains many valuable metals,

PCDDs and PCDFs in fly ash from Spanish municipal solid waste incinerators

Toxicological & Environmental Chemistry, 1992
Fly ash samples from different Spanish incinerator plants have been analysed for PCDDs and PCDFs. Total levels of dioxins and furans varies between 2.40 and 119.94 ppb. The homologue series distribution is quite similar in most samples. OCDD always exhibit higher levels than OCDF which could be due to the combustion parameters.

Alkaline bioleaching of municipal solid waste incineration fly ash by autochthonous extremophiles

Chemosphere, 2016
The increasing demand for energy and the generation of solid waste have caused an alarming rise in fly ash production globally. Since heavy metals continue to be in demand for the production of materials, resource recovery from the recycling of these wastes has the potential to delay the depletion of natural ores.

A feasibility study of municipal solid waste incineration fly ash utilisation in Estonia

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2017
The purpose of this paper is to discuss the alternative environmental management options for the utilisation of municipal solid waste (MSW) incineration fly ash (FA), which is generated at Iru Power Plant where MSW is incinerated in Estonia. To determine sustainable and economically feasible environmental management options for MSW

Chemical stability of geopolymers containing municipal solid waste incinerator fly ash

Waste Management, 2010
Municipal solid waste incinerators every year produce tons of fly ashes which, differently from coal fly ashes, contain large amounts of toxic substances (heavy metals, dioxins, furans). The stabilization/solidification (S/S) technology known as geopolymerization is proposed with the purpose to bond physically and chemically incinerator fly ashes (IFA)
