Urban mining: the gold in your old phone
E-waste is an urban mine. The 62 million tonnes discarded in 2022 held $62 billion in recoverable materials — and on the UN's own trajectory, ~70 Mt in 2025 contains roughly 560 tonnes of gold. A tonne of old phones has 40-400 times more gold than a tonne of gold ore. About 17-18 milligrams of gold are thrown away with e-waste every second. Only 22.3% gets formally recycled.
What this means for you
A single smartphone contains approximately 0.034 grams of gold (worth roughly $2 at current prices). That sounds trivial, but a tonne of old smartphones contains 300-400 grams of gold, which is 10-80 times richer than a tonne of gold ore from a mine. This is why the concept of "urban mining" exists: our cities are, functionally, mineral deposits.
The barrier to recovery is not technical; it is logistical and economic. Collecting, sorting, and processing small consumer electronics at scale is expensive, and manufacturers have historically not been required to fund it. Extended Producer Responsibility (EPR) laws in the EU now require electronics manufacturers to fund collection and recycling, but most of the world lacks equivalent regulation.
The practical takeaway: your old electronics have real material value. Before discarding any device, check whether your retailer or municipality has a takeback programme; in many regions, it does.
Gold discarded vs. total e-waste generated, today
Precious metals like gold, silver, and palladium are embedded in circuit boards, connectors, and contacts, and mostly lost forever when devices are thrown away.
The numbers: gold and valuable metals in e-waste
UN GEM 2022: $62 billion in recoverable materials in e-waste generated that year; less than 22.3% was formally recycled
One tonne of discarded circuit boards contains 40-400x more gold per tonne than gold ore from typical mines
Only 1% of rare earth element demand is met through e-waste recycling, despite critical importance for renewables and EVs
UN GEM 2019: 53.6 Mt e-waste contained $57 billion in recoverable gold, silver, copper, and other precious materials
E-waste is growing 5x faster than documented e-waste recycling (GEM 2024)
Urban mining: why your old phone is more valuable than gold ore
The $62 billion urban mine
The term "urban mine" describes the concept of recovering metals from manufactured goods rather than virgin ore. E-waste is among the richest urban mines: a single metric tonne of smartphone circuit boards can yield 300-400 grams of gold, compared to 5-10 grams from typical gold ore. The UN Global E-waste Monitor 2024 calculated that the 2022 global e-waste stream contained $62 billion in recoverable materials, more than the GDP of many developing nations, yet over 75% was lost to uncontrolled disposal or informal recycling with low recovery rates and high toxicological risk.
Informal recycling and its costs
In countries without formal e-waste infrastructure, informal recyclers recover gold and copper through open burning, acid baths, and manual dismantling, exposing workers (including children) to lead, mercury, cadmium, and brominated flame retardants. A 2022 WHO report identified e-waste as a growing public health concern for the 18 million children involved in informal recycling globally. The concentration of informal recycling in West Africa (Agbogbloshie, Ghana), South and Southeast Asia, and China makes this a systemic global justice issue as well as an environmental one.
Urban mining output growth over time
Each tonne of discarded circuit boards contains 40-800 times more gold than a tonne of gold ore, yet the global e-waste recycling rate sits below 25%. On the UN's own 2022→2030 trajectory (500 t gold in 62 Mt e-waste, rising to ~660 t in 82 Mt by 2030), roughly 560 tonnes of gold are being landfilled or incinerated in 2025 — tens of billions of dollars in recoverable value.

Key milestones in urban mining
- 2010UN estimates 33 Mt e-waste globally; Agbogbloshie (Ghana) emerges as world's largest informal e-waste site
- 2019UN GEM 2020: 53.6 Mt e-waste, a record high; $57B in recoverable materials; only 17.4% formally recycled
- 2021EU WEEE Directive target: 65% collection rate; actual EU rate ~42%, well below target
- 2022UN GEM 2024: 62 Mt e-waste; $62B recoverable; 22.3% recycled, a modest improvement but still far below need
- 2024UN GEM 2024 released: e-waste growing 5x faster than recycling; 82 Mt forecast by 2030
The economic case for urban mining
At $62B in recoverable materials from 2022's e-waste, the discarded resources exceed the annual GDP of Costa Rica
The ~560 tonnes of gold in e-waste per year (2025 est.) is more than the annual gold production of any country except China, Russia, Australia and the US
Roughly 17-18 milligrams of gold are thrown away every second — a 1-gram pea-sized nugget every minute

How the number is calculated
UN Global E-waste Monitor 2024 reports ~500 tonnes of gold in the 2022 e-waste stream (62 Mt) and forecasts ~660 tonnes in 82 Mt by 2030. Scaling linearly with total e-waste volume, 2025 (~70 Mt) contains roughly 560 tonnes of gold. Converting: 560,000 kg ÷ 31,536,000 seconds ≈ 0.01776 kg/sec = ~17.8 milligrams of gold discarded per second. At recent gold prices (~$100/g, ~$100,000/kg), that's about $1.78/second in lost gold value alone. The live counter shows cumulative grams of gold discarded today. Next authoritative update due with UN Global E-waste Monitor 2026 (late 2026).

Frequently asked questions
- How much gold is in global e-waste?
- The UN Global E-waste Monitor estimates approximately 300,000-500,000 kg (300-500 tonnes) of gold flows through the global e-waste stream each year, contained in circuit boards, connectors, and contact plating. The total value of all recoverable materials (not just gold) in 2022's e-waste was estimated at $62 billion USD.
- Is it economical to recover gold from e-waste?
- Yes, urban mining of e-waste yields gold at concentrations of 0.03-0.04% (300-400 grams per tonne), which is 10-100 times more concentrated than typical gold ore mines (0.4-5 g/tonne for large operations). Formal e-waste recyclers using hydrometallurgical or pyrometallurgical processes routinely recover gold profitably, but only 22.3% of global e-waste reaches formal recycling.
- What other valuable metals are in e-waste?
- Beyond gold, e-waste contains silver (~0.02% by weight), palladium, platinum, cobalt (from batteries), copper (major component at ~2.7% of e-waste), indium, tellurium, and rare earth elements. The combined recoverable material value of 2022's global e-waste was estimated at $62 billion, the bulk from copper and iron by weight, but gold and platinum-group metals by value.
How the e-waste gold recovery estimate is calculated
Gold content data comes from the UN Global E-waste Monitor 2024, published jointly by ITU, UNITAR, and five other UN agencies. Independent corroboration comes from the World Gold Council's annual e-waste gold supply report and academic studies published in Resources, Conservation and Recycling (Elsevier). Gold concentration data (g/tonne of circuit boards) is drawn from peer-reviewed metallurgical engineering literature.
