The research of heavy metals stabilization in the municipal solid waste incineration fly ash using silica nanocomposites

Abstract

Municipal solid waste has become a serious problem because of rapid urbanization and great economic growth. As a result of these, huge impacts on the environment lead to a lot of problems not only air, soil or water pollution but human health too. One of the solutions to manage MSW problem is incineration with energy recovery that can reduce a large amount of waste in volume. But the activity of incineration plant is associated with the formation of a large amount of hazardous waste, a significant part is fly ash which is by-products of MSW contains a high number of heavy metals and salts which are very toxic. Fly ash is a really topical question today and it is important to find out how to dispose of it properly due to hazardous contents. In this study was performed the municipal solid incineration fly ash evaluation, experimental research of heavy metal composition of seven types of a concrete mixture containing different amounts of MSWI fly ash, silica nanocomposites for the determination of the best alternative and employing a SWOT analysis.
