E-waste is any discarded product with circuitry or electrical components and a power or battery supply, from phones and laptops to fridges, lamps and solar panels. The Global E-waste Monitor estimates that 62 million tonnes were generated in 2022, up from 34 million tonnes in 2010, an average rise of 2.3 million tonnes a year. Formal collection and recycling has also grown, from 8 to 13.8 million tonnes, but generation is rising almost five times faster, so only 22.3% was documented as formally collected and recycled in 2022. About 14 million tonnes were thrown away with ordinary waste, mostly into landfills, and an estimated 18 million tonnes were handled in low- and lower-middle-income countries, mainly by informal recyclers whose work rarely appears in official data. The metals in the 2022 e-waste were worth an estimated USD 91 billion, yet recycling recovered secondary materials worth only about USD 28 billion.
The harm falls mostly on people who dismantle, burn or acid-treat old electronics by hand to recover copper, gold and other materials. Informal recycling can release up to 1,000 different chemicals, including lead, and the Monitor estimates that improper handling releases 58,000 kg of mercury and 45 million kg of plastics containing brominated flame retardants every year. WHO links exposure to stillbirth and premature birth, impaired neurodevelopment and learning, and reduced lung function, with children and pregnant women most at risk. A 2021 WHO report estimated that up to 18 million children and adolescents and 12.9 million women may be at risk of health harm from this work. Rich countries generate the most e-waste per person, and some of it is shipped to poorer countries without proper controls.
How e-waste is defined and measured
SDG target 12.5 aims, by 2030, to substantially reduce waste generation through prevention, reduction, recycling and reuse, and target 12.4 calls for sound management of chemicals and all wastes. The Global E-waste Monitor, produced by ITU and UNITAR, tracks equipment from the moment it is sold to the moment it is discarded and what happens to it then:
E-waste generated
The weight of electrical and electronic equipment that owners discard without intending to reuse it, in total and per person. It covers six categories, from large appliances and cooling equipment to screens, small IT devices, lamps and, more recently, solar panels. Batteries on their own are not counted as equipment.
Documented formal collection and recycling
The share of e-waste that official statistics record as collected and recycled in facilities meeting environmental standards. Collection and recycling by the informal sector is usually not captured, so 'not documented' does not always mean 'not recycled'.
Policy coverage
Whether a country has an e-waste policy, law or regulation, and whether it uses extended producer responsibility or sets collection and recycling targets. Having a law does not show how well it is enforced.
Transboundary movements
E-waste and used equipment shipped across borders, split into controlled shipments under waste rules and uncontrolled shipments, often declared as second-hand goods, from high-income to middle- and low-income countries.
