摘要

Global environmental, economic, and public health issues are brought on by the growing amount of electronic garbage, or “e-waste.” From its quick creation to its collection, sorting, and recycling, this article offers a thorough overview of the electronic waste lifecycle. It starts by looking at the emerging issue of e-waste creation, emphasizing geographical differences, the main types of garbage, and the possibility for recycling different electronic parts. With a focus on extended producer responsibility (EPR) frameworks and the vital role municipal collection centers play in recovering discarded electronics, the research then examine collecting procedures. It describes sophisticated sorting methods that are necessary for efficient resource recovery. Density-based techniques like separation of water and air classification are covered, along with manual and automated techniques like magnetic, eddy current, and optical separation. Modern methods like near-infrared (NIR) spectroscopy and X-ray fluorescence (XRF), which improve sort efficiency and compliance with regulations, are evaluated against chemical reclamation processes such as leaching, hydrometallurgy, pyrometallurgy, and biometallurgy. In order to achieve regulatory criteria, recycling methods are examined with an emphasis on optimizing resource recovery, protecting the environment, and conserving energy. It examined upcoming management trends and the difficulties associated with gathering and classifying e-waste.
