e-Waste is the fastest growing waste stream due to rapid technological growth, planned obsolesces in the electronics industry, and increased desire for new electronic products. E-waste now contains precious metal deposits 40 to 50 times richer than ores mined from the ground. The processes involved in e-waste recycling are collection, dismantling, pre-processing, end processing, and final metal recovery. To achieve environmental sustainability, the trend in e-waste management is green computing.

Electronics equipment has become a buzzword in the world of solid waste management and metal recovery due to the large volumes of precious metals utilized in equipment. Most of the studies nowadays revolve around recovering the metals from e-waste using large amounts of solvents that be likely to be highly toxic with a specific limit on the recovery. Nippon E-Waste processes are utilized to recover the metallic ions to bare metals, which can be utilized as secondary resources for the IT industries. focus on the electrochemical processes, to enhance the recovery of these different elements that are being, accumulated from the e-waste and further detail the solvent, electrode, and conditions required for optimizing the migration of the target metals that are either present in the electrolytes as leachate or as contact scrap.
