E-Waste: Pollutants, Health Impacts and Status in India

Environment & Ecology › Waste Management · Topic 14.5

Electronic waste (e-waste) is discarded electrical and electronic equipment such as computers, phones, televisions, refrigerators, batteries and lamps. It contains valuable materials, including gold, silver, copper and rare earth elements, but also hazardous substances: lead in solder and glass, mercury in lamps and switches, cadmium in batteries and chips, hexavalent chromium, brominated flame retardants, polychlorinated biphenyls, beryllium and arsenic. Crude recycling, such as open burning of wires and acid leaching of circuit boards, releases dioxins, furans and metals that damage the brain and nervous system (lead), kidneys (cadmium), lungs and skin, and harm children and pregnant women. The Global E-waste Monitor reported about 62 million tonnes of e-waste worldwide in 2022, of which only about a fifth was documented as properly recycled. India is among the largest generators, with over 1.5 million tonnes a year, mostly handled by the informal sector in places such as Moradabad, Seelampur and Mandoli; check the latest CPCB and Global E-waste Monitor figures.

Where Does It Fit?

This topic follows the general solid waste rules and takes up the fastest-growing waste stream, e-waste. It leads to the E-Waste Rules, 2016 and other special wastes. Previous topic: Solid Waste Management (SWM) Rules, 2016. Next topic: E-Waste (Management and Handling) Rules, 2016.

What Are the Pollutants and Health Impacts of E-Waste?

Pollutant	Source and health impact
Lead	Solder, CRT glass, batteries; damages brain and nervous system, especially in children
Mercury	Lamps, switches, flat screens; damages brain, kidneys and developing fetus
Cadmium	Batteries, chips, semiconductors; damages kidneys and bones, carcinogen
Hexavalent chromium	Metal coatings; causes skin and lung problems and cancer
Brominated flame retardants	Plastic casings and circuit boards; disrupt hormones and nervous system
PCBs, dioxins and furans	Capacitors and burning of plastics; toxic and carcinogenic
Beryllium and arsenic	Contacts and chips; lung disease and cancer

What Is the Situation in India?

Generation: over 1.5 million tonnes a year, rising steadily; India is among the top three or four countries
Informal sector: most e-waste is dismantled by small, unregistered units using crude methods
Hotspots: Moradabad (brass), Seelampur (Delhi), Mandoli, Bengaluru and Mumbai
Collection gap: a small share is collected through formal producer-responsibility systems
Imports: illegal import of foreign e-waste has been reported
Children: often work in dismantling, which raises health risks
Urban mining: recovery of metals from e-waste can supply materials with lower impact than mining
Law: E-Waste (Management and Handling) Rules, 2016 and later E-Waste (Management) Rules, 2022

What Else Should You Remember?

E-waste categories: large and small household appliances, IT and telecom equipment, lighting, medical devices, toys and tools
Global E-waste Monitor: a UN-backed report by UNITAR, ITU and others, with 2024 edition giving 62 million tonnes for 2022
Recycling rate: only about a fifth of global e-waste is documented as recycled
India’s rank: often listed as the third largest generator after China and the US
Per capita: India’s per capita e-waste is much lower than rich countries
Valuable metals: a tonne of mobile phones holds far more gold than a tonne of ore
Urban mining: recovering metals from products instead of mines
Open burning: releases dioxins and heavy metals
Acid baths: used to extract gold and pollute soil and water
Rag pickers: informal workers face lead and other exposures
Planned obsolescence: short product life increases waste
Right to repair: India launched a Right to Repair portal in 2022
Basel Convention: controls trade in hazardous wastes including e-waste
Basel Ban Amendment: prohibits export of hazardous wastes from developed to developing countries
Producer responsibility: manufacturers must collect and recycle end-of-life products
CPCB inventory: CPCB publishes estimates of e-waste generation and dismantling capacity
Authorised recyclers: registered with CPCB, many working below capacity
Mercury lamps: CFLs and tube lights contain mercury and need separate collection
Batteries: lithium-ion batteries from phones and EVs pose fire and metal recovery issues
Data security: devices must be wiped before recycling
Awareness: most consumers do not know where to give e-waste

Link to next: see E-Waste (Management and Handling) Rules, 2016
Link to mercury: see Mercury Pollution
Caution: generation and recycling figures vary across reports, so quote with the source
Exam hint: match each toxic metal with its source and health effect
Shipbreaking and import: old computers and ships can bring hazardous waste into India, so import of e-waste is restricted
Child health: children near informal dismantling sites show high blood lead levels in studies
Women workers: women often handle sorting and manual dismantling with little protection
Lithium-ion batteries: phones, laptops and EVs add batteries that can catch fire in waste trucks and plants
Design for recycling: products designed to be modular and repairable are easier to recycle

Why Does It Matter for the Exam?

Brain damage: Lead
Kidney damage: Cadmium
Handlers: Informal sector
Current affairs link: EPR certificates and right to repair
Common errors: calling e-waste only toxic and ignoring its resource value

As an analytical point, e-waste is both a hazard and a resource. Safe formal recycling and design for repair can protect workers and recover valuable metals, while informal dismantling needs to be brought into the regulated system rather than banned outright.

Frequently Asked Questions

What is e-waste?

E-waste is discarded electrical and electronic equipment, including computers, mobile phones, televisions, refrigerators, batteries, lamps and other gadgets, whether broken or obsolete. It contains valuable metals such as gold, silver and copper as well as hazardous substances such as lead, mercury, cadmium and brominated flame retardants.

Why is e-waste hazardous?

E-waste contains toxic substances that can leak or be released when equipment is broken, burned or treated with acids. Lead harms the brain, cadmium damages kidneys, mercury affects the nervous system and flame retardants and dioxins disrupt hormones and cause cancer. Workers and nearby residents, especially children, face the highest risks in informal recycling.

How much e-waste does India generate?

India generates over 1.5 million tonnes of e-waste a year according to official estimates, and the amount is growing fast with rising use of electronics. It is among the world's top few generators, though its per capita amount is low. Only a small portion is collected by formal recyclers, while the rest is handled informally.

What is urban mining?

Urban mining is the recovery of valuable materials, such as gold, silver, copper and rare earths, from discarded products like e-waste instead of extracting them from natural ore. It can reduce the environmental harm of mining and supply critical materials, if recycling is done by formal, safe and efficient methods.

Where does most of India's e-waste get processed?

Most e-waste in India is processed by the informal sector in clusters such as Moradabad, Seelampur in Delhi and Mandoli, using manual dismantling, open burning and acid leaching. This recovers some metals cheaply, but exposes workers and the environment to toxic substances, which is why formalisation and producer responsibility are central to the rules.
