Electronic waste generation and accumulation keeps on increasing and possess a serious threat to the environment. To find a legitimate or suitable eco-friendly method for metal recovery from e-waste this includes the noble metals, rare earth metals and also the heavy metals. Methods like magnetic separation, Eddy current separation and Electrostatic separation results in separation of metallic parts from the crushed e-waste and its PCBs (Printed Circuit Boards). For synthesising nanoparticles out of the recovered metallic parts, pyrometallurgy using Tubular furnace, hydrometallurgical methods, cryo-milling techniques and bio-approaches using plant leaf are utilised. Heavy metal in Electronic waste plays a vital role in polluting the ecology/environment. Researchers are trying to enhance the metal recovery from e-waste process by improving the environmentally friendly approaches. In this review, harmless to the ecosystem draws near and the techniques that depicts about the Nanoparticle synthesis from electronic waste printed circuit boards are critically reviewed.
