What is e-waste?
E-waste (electronic waste) is any electrical or electronic item that is old, broken or no longer wanted: mobile phones, chargers, computers, printers, TVs, fridges, batteries and cables. As we change phones and laptops quickly, the e-waste pile grows every year. India is among the top producers of e-waste in the world.
Hazards of e-waste
E-waste has useful metals (copper, gold, silver) but also harmful ones. When it is dumped in the open or burnt to take out metals, these poisons escape.
- Lead (in old screens, solder): harms the brain, nerves and kidneys, especially in children.
- Mercury (in some lamps, switches): damages the nerves and brain.
- Cadmium (in batteries): harms kidneys and bones.
- Burning plastics releases toxic gases such as dioxins; they cause breathing problems.
Effects on the environment
Soil: metals seep in and enter crops. Water: they reach groundwater and rivers. Air: smoke from burning pollutes the air. Informal workers, often children, who break e-waste by hand are hit the hardest.
E-waste management
The best way is the 3 Rs, in this order:
- Reduce: buy only what you need, use devices longer.
- Reuse: repair, upgrade, sell or donate working devices; reuse parts.
- Recycle: send the rest to an authorised recycler, who safely takes out metals and plastics.
E-waste rules in India
The E-Waste (Management) Rules, 2022 (from the Ministry of Environment, under the Environment Protection Act) follow Extended Producer Responsibility (EPR): the company that makes or sells a product must collect it back at the end of its life and get it recycled. Consumers should give e-waste only to authorised collection centres or take-back schemes, never to the dustbin.
Health effects of technology use: body
Using computers and phones for long hours can cause:
- Eye strain (dry, tired, blurry eyes) from staring at bright screens and blinking less.
- Neck and back pain from bending over phones or a low screen ('text neck').
- Repetitive Strain Injury (RSI) and carpal tunnel pain in the wrist and fingers from long typing or gaming.
Ergonomics
Ergonomics means designing and arranging the workplace so the body is comfortable. Tips: top of the screen at eye level, about an arm's length away; back straight and supported; feet flat on the floor; wrists straight while typing; good room light without glare.
Health effects of technology use: mind
Internet or gadget addiction means you cannot control screen use even when it harms studies, sleep or relationships. Signs: feeling restless without the phone, losing track of time, skipping meals or sleep. Too much screen time, especially at night, also affects sleep because bright screens keep the brain awake. Social media comparison can cause stress and low mood.
Healthy habits: the 20-20-20 rule for eyes, screens off one hour before bed, fixed screen-free times (meals, family time), outdoor play and exercise, and using screen-time limits on the phone.
Key formulas and definitions
- E-waste = discarded electrical/electronic equipment
- Toxic metals: lead, mercury, cadmium (+ dioxins from burning)
- Management order: Reduce β Reuse β Recycle (authorised recycler)
- E-Waste (Management) Rules 2022: EPR = maker takes back
- Eye care: 20-20-20 (20 min, 20 feet, 20 s)
Worked examples
1. Arrange these in the 3R order of preference: (a) send an old laptop to an authorised recycler, (b) repair the laptop and give it to a cousin, (c) do not buy a new laptop while the old one works.
Reduce (c) first, then Reuse (b), then Recycle (a). Reducing avoids waste entirely, so it comes first.
2. A scrap dealer burns cables in the open to get copper. Name two harms.
Burning plastic releases toxic gases such as dioxins that cause breathing problems; metal residue pollutes the soil and water nearby.
3. Rohan studies on his laptop kept on his lap with his head bent for 4 hours. Name two problems and two fixes.
Problems: neck/back pain and eye strain. Fixes: put the laptop on a table with the screen at eye level (use a stand), and follow 20-20-20 with short breaks.
4. What does Extended Producer Responsibility mean for a mobile phone company?
The company must set up collection (take-back) of its old phones and make sure they are recycled by authorised recyclers, meeting yearly collection targets.
Common mistakes
- Putting old batteries and phones in the normal dustbin. They must go to e-waste collection points.
- Thinking recycling is the first choice. Reduce and reuse come before recycle.
- Thinking only the eyes are affected by screens. Posture, wrists, sleep and mood are affected too.
- Selling e-waste to informal burners because they pay more. It poisons workers and the environment; use authorised recyclers.
