Laboratory chemical waste management is an essential factor to be addressed in parallel to a research study. This publication described the use of a simple technique, the galvonostitic mehtod, to manage the CdTe electrolyte waste generated in CdS/CdTe solar cell fabrication by extracting the heavy metal cadmium from the waste. About 98% of the cadmium in the  waste solution can be successfully removed using the galvanostatic process under a low current. The materials extracted can be use as precursors for CdTe deposition by close spaced sublimation or thermal evaporation after optimization.
