Solid By-Products from MSW Incineration

Management of bottom ash is a relatively less severe problem. In the case of a continuous moving grate furnace, bottom ash is discharged at the bottom of the 

When no use can be found for the ash, then this need to be landfilled as a special waste or sometimes (if it does not comply with the toxicity leaching tests) as a dangerous waste. Clearly, its landfill disposal, particularly if it is labeled as a dangerous waste, poses environmental and economical issues, linked to the risk of leaching and to the sensible increases of the overall cost of MSW management.

Disposal of Solid By-Products from MSW Incineration Processes... 

MSW incineration is attractive because it greatly reduces both the mass and volume of treated waste. As reported by Arena and Mastellone (1998), the mass of the solid by-products (essentially slag deriving from the incineration process, plus a mixture of fly ash and other solids captured in the flue gas treatment section of the... 

Plasma torch—based applications for waste treatments include fly ash from incineration processes, asbestos-containing waste, sanitary waste, waste containing organo-halogenated compounds, low-level radioactive waste, and even traditional RDF. In particular, plasma applications represent a very interesting technical solution for the treatment of fly ash from MSW/RDF incineration because the solid by-product, with its extremely low tendency to leaching, can be disposed off as a...
