The process of copper recovery from waste printed circuit board assembly (PCBA) hasremained a large fraction of solid waste called “Nonvaluable Residue (NVR)”. This residue is considered tobe a hazardous waste because Pb, Cu, and Sb exceed the regulatory levels. Solidification/Stabilization (S/S)treatment technique is selected to improve waste characteristics before disposal of in hazardous wastelandfills. In this study, a cement-based solidification/stabilization was used to treat NVR. Unconfinedcompression strength test (UCS) and toxicity characteristic leaching procedure (TCLP) were mainly used forphysical and chemical characterization of the solidified/stabilized products. After curing for 28 days, thecompressive strength and heavy metal leachability (Pb, Cu, Sb) were tested. The results showed that thecompressive strength of blank sample was 20.75 MPa while compressive strengths of the solidified/stabilizedNVR products were 7.36, 4.17 and 1.35 MPa for 20%, 30% and 40 wt% of NVR, respectively. Allexperimental mixture ratios satisfied the UCS requirements (0.35 MPa). In addition, the concentrations of Pb,Cu, and Sb in the TCLP leachate of all solidified/stabilized NVR products were lower than the limit valueand the original waste. This study indicated that cement-based S/S treatment process was able to improveheavy metal immobilization and subsequently minimize potential environmental impacts in landfill disposal.
