Coal ash from power plants is divided into fly ash and bottom ash, which are produced after burning bituminousanthracite coal at 1,600oC. Coal ash is composed of fly ash (82%) and bottom ash (18%); while most fly ash is recycledas ready-mix concrete admixture and cement additive, bottom ash is left unused in landfill sites located within powerplant grounds. This has been studied less comprehensively than fly ash; therefore, our aim was to assess the recyclabilityof the bottom ash generated by two (A & B) thermal power plants and thus identify the characteristics of hazardoussubstances in coal ash that are generated in power plants and evaluate the environmental contamination likelihood in therecycling of the produced coal ash. Currently, emitters such as thermal power plants have various requirements for therecycling of coal ash (bottom ash and they are also required by law to consider how the country’s environmental impactmay be affected by recycling large amounts of coal ash. The concentrations of hazardous substances contained in coalash (bottom ash) are generally lower than the criteria for soil contaminants and the standard for hazardous substancescontained in designated waste. We found no significant leaching of heavy metal and its concentration; however, the levelsof heavy metals in coal ash were generally low. The results of column leaching testing for potential environmental impactassessment indicated that increased leaching time might lead to the reduced ionic concentration of coal ash.
