摘要

The exponential growth of electronic waste (E-waste) poses a significant environmental and health crisis. The devices that humans simply discard because they are no longer “useful” can actually cause more harm than expected. This creates an alarming situation particularly in developing countries like India. While E-waste contains valuable metals such as gold, silver and copper, it also harbors hazardous substances including persistent organic pollutants (POPs), dioxins and heavy metals like lead, mercury, cadmium etc. More concerning is the presence of radioactive materials such as Uranium (U-235, 238), Thorium (Th-232), Americium (Am-241), Cobalt (Co-60), Radium (Ra-226) etc. which pose long-term environmental and health risks due to their radioactive decay and bioaccumulation. India’s E-waste generation surged by 73% over five years, rising from 1.01 million metric tons in 2019–20 to 1.75 million metric tons in 2023–24. This sharp increase was largely driven by the growing demand for electronic devices, fueled by the widespread shift to work-from-home and remote learning during the Covid-19 pandemic. This article revolves around the composition, hazards, materials and management of nuclear E-waste, with an emphasis on its radioactive components. Several policy suggestions are proposed, including the establishment of color-coded PCBs to identify radioactive materials, strict monitoring of bulk E-waste producers, and public awareness campaigns to promote responsible disposal.
