In this study, municipal solid waste incineration fly ash (MSWIFA) was pretreated with CO 2 via slurry carbonation (SC) and dry carbonation coupled with subsequent water washing (DCW). Both the treated MSWIFAs were then used as cement replacement in cement pastes by weight of 10%, 20% and 30% to investigate the …
In order to reduce municipal solid waste incinerator (MSWI) ash, the effect of replacement level of high calcium fly ash by MSWI bottom ash on fly ash based geopolymer properties were studied. The results were compared to cement matrix containing MSWI bottom ash. It showed that the 20% MSWI bottom ash replacement …
The reasonable use of bulk industrial solid waste can solve the problem of waste accumulation and reduce carbon emissions during industrial production by replacing primary resources with renewable ones. Therefore, the resource utilization of industrial …

1. Introduction. Gasification is considered an alternative to conventional incineration for municipal solid waste (MSW) because it can produce valuable syngas while releasing the burden of landfilling (Arena, 2012).By applying a high temperature to melt most MSW, slagging-gasification generates slag, metal alloys, and gasification fly ash …
Application of a combination of municipal solid waste incineration fly ash and lightweight aggregate in concrete ... the mixture ratio of LWA, fly ash, cement, and fine sand is 3.0: 0.1: 0.9: 2.0 based on dry weight. Meanwhile, the results of leaching test are much lower than the concentration limits of hazardous constituents of hazardous waste ...
As a hazardous waste, the management of MSWI fly ash is a crucial issue, and before its disposal into final landfill MSWI, fly ash required further detoxifying treatment (Ling and Hou, 1998). The content distributions and characteristics of dioxins in the fly ash depend on the constituents of incinerated MSW, the varieties of incineration ...
At this time, the Solid Waste Program is reviewing the rule and comparing its requirements with those of Kentucky regulations for the disposal of coal combustion residuals. Currently, Kentucky regulations designate coal ash ponds as permits-by-rule as long as they are in compliance with a Kentucky Pollutant Discharge Elimination System (KPDES ...
The use of bottom ash in a hybrid binder system consisting of OPC, MSWI bottom ash and fly ash, as well as a 5% mix of CaSO 4 and Na 2 SO 4 as the activator was investigated . It showed a 40% strength loss for this mix in comparison with a …
Environmental Benefits and Its Adverse Effect. If manufactured cement is substituted with fly ash, there are major environmental benefits. These advantages include: (1) longer …
Waste-to-energy technique is widely applied as an efficient way to manage municipal solid waste (MSW). It can largely reduce the mass and volume of MSW (Phongphiphat et al., 2011; Tang et al., 2015; Xuan et al., 2018b).However, the combustion residues after incineration, including incineration bottom ash (IBA) and incineration fly …
Harmful algal blooms are increasingly prevalent globally, posing significant threats to water safety and ecological health. In this study, a novel positive charged buoyant cenosphere (FABC@CTS) was developed for capturing and floating algal cells using chitosan (CTS) and an easily available waste material—fly ash buoyant cenospheres …

Municipal solid waste (MSW) is one of three major waste-to-energy technologies (the others are anaerobic digestion and biomass). MSW can be combusted in waste-to-energy facilities as a fuel with processing methods such as mass burn, refuse-derived fuel; or it can be gasified using pyrolysis or thermal gasification techniques.
The main objectives of thermal treatment of municipal solid waste are mass and volume reduction, destruction of organic contaminants, energy and metal recovery. Two main residues are produced after incineration on grates at 800–1000 °C: bottom ash (20 wt.% of the waste input) and fly ash (2 wt.%).
