Abstract

This paper attempts to propose an innovative strategy/model for the recovery of precious metal like silver from e-waste by employing combined technologies. Firstly, silver is leached using free cyanide from electronic scrap thereby forming silver-cyanide complex. In the second step, silver-cyanide is removed using biosorption using passive Eicchornia roots powder biomass. Lastly, the residual silver-cyanide remaining after biosorption is biodegraded using live heterotrophic bacterial consortium. Feasibility study showed that the overall system strategy worked efficiently for the management of e-waste.
