Abstract

Solidification/stabilization (S/S) is a process which aims to immobilize the inorganic component of many hazardous wastes. Cement is one of the most common binders being used. This study investigated the potential of using sugarcane bagasse ash (SCBA) as a partial substitute to ordinary Portland cement (OPC) as a binder to treat the Zn-containing galvanized steel sludge (SLU). All the treatments passed the strength test where Treatment 4 (60% OPC, 30% SCBA, 10% SLU) has the highest strength of 6.75 MPa. All the treatments also passed the durability test where Treatment 3 (60% OPC, 10% SCBA and 40% SLU) showed the lowest percent weight loss of 0.1381%. all the treatments also passed the leach test where Treatment 9 (40% OPC, 50% SCBA and 10% SLU) had the lowest amount of zinc that leached out with the value 0.310 ppm. Based from material costing, Treatment 7 had the highest percent savings of 59.99%. From this study, it can be concluded that the co-disposal of SCBA and Zn-containing galvanized steel sludge, which are both industrially produced waste, can improve the quality of the solidified/stabilized material by effectively stabilizing the heavy metal content of the waste and contributing to the development of physical strength and stability of the solidified material.
