Write in brief on e-waste management.

E-Waste Management: Ecological Risks, Regulatory Framework, and Sustainable Solutions:

1. Concept & Composition: End-of-life, obsolete electrical and electronic equipment (EEE)—including integrated circuit boards, computing hardware, smartphones, and displays.
2. Severe Toxicological Hazards:
   • Hazardous Heavy Metal Leaching: Contains neurotoxic Lead (Pb), bioaccumulative Mercury (Hg), nephrotoxic Cadmium (Cd), and carcinogenic dioxins.
   • Informal Backyard Recycling: Open-air acid leaching and unregulated incineration poisoning urban airsheds and subterranean aquifers.
3. Statutory Framework & Sustainable Governance (E-Waste Rules 2022):
   • Extended Producer Responsibility (EPR): Enforcing legally binding take-back, collection, and recycling quotas on original electronics equipment manufacturers.
   • Circular Economy & Urban Mining: Industrial pyrometallurgical and hydrometallurgical recovery of high-value Precious Metals (Gold, Silver) and Strategic Rare Earths.
   • Pioneering Institutional Initiative: India's first dedicated municipal E-Waste Clinic commissioned in Bhopal, Madhya Pradesh.
