E-waste in urban India: causes, impacts and management

Introduction: what e-waste is

E-waste is discarded electrical and electronic equipment. The E-Waste (Management) Rules, 2022 define it as such equipment, including solar photo-voltaic modules, panels or cells, thrown away whole or in part as waste, together with the rejects of manufacturing, refurbishing and repair. In a city it means old mobile phones, laptops, chargers, televisions, refrigerators, air conditioners and the like.

Causes of e-waste in urban India

1. Fast replacement of gadgets. Urban households and offices upgrade phones, laptops and appliances long before they stop working. Consumer goods are often made to look out of date by advertising well before they actually wear out.
2. Rising incomes and digital life. Work, study, banking and entertainment in cities now run on devices, so the number of devices per person keeps growing; more devices in use means more devices discarded later.
3. Large institutional users. Offices, banks, colleges and IT firms replace equipment in bulk, so a single upgrade can retire hundreds of devices at once.
4. Weak collection. Without convenient take-back points, e-waste is mixed with household garbage or sold to scrap dealers.

Impacts

1. Toxic substances. Electrical and electronic equipment can contain lead, mercury, cadmium, hexavalent chromium and brominated flame retardants; this is why rule 16 caps them in new equipment (0.1 per cent by weight in homogeneous materials, and 0.01 per cent for cadmium).
2. Human health. Lead can damage nerve tissue and lead to brain disease, and the body has only a limited ability to get rid of mercury, which becomes more concentrated as it passes up the food web. People who dismantle or burn e-waste by hand, without protection, are the most exposed.
3. Soil and groundwater. Hazardous wastes are mostly dumped on or in land, so their most serious effect is contaminated groundwater, which is often impossible to clean once polluted.
4. Loss of resources. E-waste holds precious and semi-precious metals and rare earth elements that a proper recycler can recover; dumping wastes this secondary source of materials.

Management

The main law is the E-Waste (Management) Rules, 2022, in force from 1 April 2023; they replaced the 2016 Rules.

• Who is covered. The Rules apply to every manufacturer, producer, refurbisher, dismantler and recycler of the listed equipment, but not to waste batteries (Battery Waste Management Rules, 2022), packaging plastics (Plastic Waste Management Rules, 2016), micro enterprises or radioactive waste.
• Registration. Manufacturers, producers, refurbishers and recyclers must register on the central portal; no entity may do business without registration or deal with an unregistered one (rule 4).
• Extended producer responsibility. Each producer must meet recycling targets set in Schedules III and IV, and may meet them only through registered recyclers.
• Refurbishing extends a device's working life for the same use, which delays it becoming waste.
• Cleaner design. Rule 16 limits hazardous substances in new equipment, so that the e-waste of the future is less toxic.
• Citizens in a city can repair before replacing, give old devices to authorised collection points, and never burn or bin them with wet waste.

Conclusion

E-waste in urban India grows with incomes and the pace of replacing gadgets. It is both a health hazard, because of its toxic metals, and a resource, because of the metals it holds. The 2022 Rules put the burden on producers through registration and recycling targets; they work only if households, offices and local bodies send their discarded devices into the formal recycling chain.
