Abstract
Zinc is one of the dangerous elements that is frequently present in municipal solid waste incinerator ash. When exceeding specific limits, there are various diseases and disorders caused by accumulation of zinc in nature as their characteristics is not biodegradable. By using zinc oxide to imitate zinc sludge, this study reveals the immobilization mechanisms that occur when zinc and ceramic precursors are used as waste-to-resources strategies. From the result, immobilization occur better at higher temperature at 10000C where the formation of Al2O4Zn is higher. Meanwhile, ratio 1:1 of ZnO and Al2O3 shows a better result of formation Al2O4Zn. Hence, it is possible to use the sintering process with precursors to turn hazardous wastes into secure products where the heavy metals can form phases that can demonstrate adequate stability due to irreversible phase transformation.
