Abstract

This study applied a stabilization method to treat contaminated soil. First, the stabilization efficiency and the proper mixing ratio were derived by mixing the stabilizer (KSPA) and contaminated soil. Subsequently, to improve the limitations of the stabilizer, waste resources (eggshell, pig bone, and steel slag) were incorporated to evaluate the stabilization efficiency. The modified stabilizer showed a significant reduction in the amount of heavy metal leaching when compared with other leaching yields (raw materials (contaminated soil) and applying the KSPA only). After 28 days of mixing the waste resources with KSPA, lead and chromium, excluding arsenic, showed up to 100% stability, confirming improved stabilization efficiency in complex contaminated soil.
