Waste from electronics and sensors is one of the fastest-growing streams due to rapid technological obsolescence. It includes printed circuit boards (PCBs), connectors, capacitors, and microchips, all of which may contain gold, silver, copper, and palladium. These metals are critical for functionality and are highly recyclable. Recycling involves dismantling components and recovering metals through smelting or chemical processing. Proper handling of electronic waste reduces environmental harm and contributes to the circular economy of critical raw materials.
