Abstract

The issue of electronic waste, or e-waste, is indeed a significant global concern with far-reaching environmental and health implications. As technology continues to advance and become more integrated into our daily lives, the disposal of obsolete or broken electronic devices has become a pressing issue. This waste not only contains valuable metals but also toxic substances, posing significant challenges for disposal and management. Improper disposal of e-waste is a significant contributor to environmental pollution. When e-waste is incinerated or exposed to heat, toxic chemicals are released into the air, contributing to air pollution and potentially harmful health effects for nearby communities. Moreover, when e-waste is disposed of in landfills, it can lead to the leaching of hazardous compounds into the soil and groundwater, thereby contaminating the environment and posing risks to ecosystems and human health. The toxic metals found in e-waste, including mercury, lead, cadmium, and arsenic, can result in severe health repercussions for individuals exposed to them. Long-term exposure to these substances can lead to neurological damage, developmental disorders, respiratory issues, and various other health problems. Electronic devices contain valuable resources, including gold, silver, copper, and platinum. Inadequate management of e-waste leads to the squandering of these valuable resources, exacerbating resource depletion and necessitating more extensive mining endeavors to fulfill demand. Despite the challenges posed by e-waste, there are also opportunities for economic growth and resource recovery. Implementing efficient e-waste management practices, such as recycling and recovery of valuable materials, can create new economic opportunities while mitigating environmental and health risks. Harnessing valuable metals from e-waste through recycling presents a promising strategy to alleviate the environmental repercussions of electronic waste. Various methods, including mechanical processing, pyrometallurgy, hydrometallurgy, and bioleaching, can be employed to extract valuable metals from e-waste while minimizing environmental pollution. Tackling the challenges presented by e-waste demands a comprehensive strategy encompassing technological innovation, policy interventions, public awareness initiatives, and collaborative endeavors among diverse stakeholders. By implementing sustainable e-waste management practices, we can mitigate environmental pollution, protect human health, and harness the economic potential of recycling and resource recovery.

Keywords: E-waste, Copper Recovery, Extraction, Mechanical Processing, Pyrometallurgical Processing.
