Variation in chemical composition of MSWI fly ash and dry scrubber residues

Waste Management, 2021
Our society generates extensive amounts of municipal solid waste (MSW), which are mainly incinerated for volume reduction and energy recovery. Though, MSW incineration generates hazardous air pollution control (APC) residues that must be treated and deposited in appropriate landfills.

The environmental costs of clean cycles: Quantitative analysis for the case of PVC window profile recycling in Germany

Journal of Industrial Ecology, Volume 28, Issue 6, Page 1755-1770, December 2024.
Abstract Recycling schemes for long‐lived products are challenged by the presence of “legacy substances,” which have been used in production in the past, but are nowadays classified as substances of concern. This study quantitatively evaluates the trade‐offs between phasing out legacy substances, increasing circularity levels, and reducing life cycle ...

Effect of Mass Proportion of Municipal Solid Waste Incinerator Bottom Ash Layer to Municipal Solid Waste Layer on the Cu and Zn Discharge from Landfill

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
Municipal solid waste incinerator (MSWI) bottom ash is often used as the protection layer for the geomembrane and intermediate layer in the landfill. In this study, three sets of simulated landfills with different mass proportion of MSWI bottom ash layer to municipal solid waste (MSW) layer were operated.

Environmental and mechanical analysis of low‐carbon concrete with vitrified MSW incineration bottom ash as cement replacement

Structural Concrete, Volume 25, Issue 4, Page 2968-2990, August 2024.
Abstract The building sector is responsible for about 37% of the global carbon dioxide emissions, 6% of which result from concrete (and particularly cement) production. Using recycled and supplementary cementitious materials and adopting a whole building life cycle approach can be seen as multi‐beneficial strategies for materials' design.

Improving metal extraction from MSWI fly ash through different experimental conditions for the electrodialytic treatment method

, 2021
Municipal solid waste incineration (MSWI) results in fly ash as one of the residues. MSWI fly ash is classified as hazardous waste due to the high concentrations of leachable inorganic elements and has to be disposed of in hazardous waste disposal sites.

The Levels, Speciation, and Influencing Factors of Mercury in MSWI Fly Ashes of a High Geological Background Area

Toxics
Fly ash (FA) captures most mercury (Hg) in the waste stream during municipal solid waste incineration (MSWI), and the content and speciation of Hg in MSWI fly ash (MSWI-FA) have a significant impact on the ecological environment.

Mechanisms of solidification of cadmium in municipal solid waste incineration fly ash usinga slag cemented backfill agent

工程科学学报, 2018
In cement production, the synergistic use of municipal solid waste incineration (MSWI) fly ash provides a novel approach to solve the problem of the increasing productions of fly ash and heavy metal ions. In this study, slag-steel slag based cementitious
