The electronics industry is the world's largest and fastest growing industry. This consumer-centric industry's combination oftechnology advancements and quick product obsolescence creates new environmental issues. There is an urgent need toaddress the volume and toxicity of electronic waste generated. Printed circuit boards (PCBs) are a significant component ofelectronic trash, containing mostly heavy metals such as copper (Cu), tin (Sn), zinc (Zn), and lead (Pb). Metal recovery andrecycling from PCBs is an important step in pollution prevention. Researchers have devised many methods for recoveringprecious metals from PCBs, including gravity separation, magnetic separation, and electrostatic separation, as well as PCBseparation using the organic solvent technique, leaching method, bioleaching method, or a combination of these methods. Thisresearch provides a brief summary of India's present e-waste status, environmental and health risks, continuing waste disposaland recycling activities, and emphasizes the recovery of heavy metals from PCBs by systematic leaching/bioleaching.
