The one fact that should stop you in your tracks
There are more smartphones on Earth than there are people. As of 2024, there are roughly 8.9 billion active mobile connections worldwide against a global population of around 8.1 billion, according to GSMA Intelligence. Let that sit for a moment. We've built a civilisation where the average person owns more than one phone - and yet millions of those devices will end up in a drawer, a landfill or an incinerator before anyone extracts a single gram of what's inside them.
That's not just wasteful. It's genuinely baffling when you understand what's actually in these things.
Here are 12 facts that put it all into perspective - some will make you angry, some will make you laugh, and at least one will make you dig out that old iPhone from your bedside table.

Mind-blowing numbers: phones, waste and the scale of the problem
1. The UK has roughly 125 million unused phones sitting in homes right now. That figure, cited by Material Focus in their 2023 research into electrical waste, is staggering. That's almost two unused handsets for every household in the country. We upgrade, we forget, we stuff them in drawers. Meanwhile, each one contains materials that took enormous energy and environmental cost to extract from the ground.
2. Globally, a new smartphone is sold approximately every 0.4 seconds. Statista data puts annual global smartphone shipments at around 1.2 billion units per year. That's over 3.2 million phones a day. The manufacturing pipeline never stops - which makes the recycling pipeline's sluggishness all the more stark by comparison.
3. The world generated 62 million tonnes of e-waste in 2022 - the highest ever recorded, according to the UN's Global E-waste Monitor. That's heavier than 800 fully loaded Airbus A380 superjumbos taking off every single day of the year. Phones are a fraction of that total, but they're among the most resource-dense devices in the pile.
4. Less than a quarter of that e-waste was formally recycled. The UN puts the documented recycling rate at just 22.3%. The rest was either dumped, incinerated or handled informally in ways that release toxic materials into soil and water. This is the gap that proper recycling programmes - and services like OnRecycle - exist to close.
What's actually inside your phone? The precious metals breakdown
5. Your phone contains real gold - roughly 0.034 grams of it. That might sound trivial, but scale it up. A tonne of smartphones contains about 300 to 350 grams of gold, according to research from the Royal Society of Chemistry. A tonne of gold ore from a typical mine? Around 5 to 6 grams. Your phone is, gram for gram, a richer gold deposit than most of what's still in the ground.
6. Gold isn't even the most interesting material in there. A typical modern smartphone contains around 0.015 grams of palladium, 0.004 grams of platinum and roughly 0.34 grams of silver. It also contains copper (around 15 grams), cobalt (about 5-7 grams) and a cocktail of rare earth elements including neodymium, praseodymium and terbium. These aren't incidental traces - they're doing specific, irreplaceable jobs inside your device. The vibration motor, the speaker magnets, the camera autofocus mechanism - all rely on rare earths.
7. Some of those rare earth elements come from genuinely scarce places. Around 60% of the world's cobalt supply comes from the Democratic Republic of Congo, according to the US Geological Survey. China controls roughly 85% of global rare earth processing capacity. When you recycle a phone, you're not just recovering metal - you're theoretically reducing the geopolitical pressure on some of the world's most contested supply chains. That's a bigger statement than most people expect from dropping a phone in a recycling bin.

Wild comparisons that put e-waste in perspective
8. The total value of raw materials in 2022's global e-waste pile was estimated at $91 billion. The UN calculated that figure - and less than a quarter of it was recovered. We are, as a species, burying the equivalent of a mid-sized country's GDP worth of materials every year. The gold alone in annual global e-waste is worth more than the GDP of many nations.
9. If you stacked every unused phone in the UK on top of each other, the tower would reach roughly 12,500 kilometres high. A standard smartphone is about 7-8mm thick. At 125 million units, that's a stack stretching past the Moon's orbit. It's a silly image, but it lands the point better than any bar chart.
10. Manufacturing a new smartphone produces around 70kg of CO2 equivalent, according to lifecycle analysis from researchers at McMaster University in Canada. About 80% of a phone's total lifetime carbon footprint is generated before you even switch it on - in mining, processing and manufacturing. Every time someone recycles or resells a phone instead of buying new, they're avoiding the majority of that carbon cost. Selling your old phone isn't just financially smart - it's one of the most effective individual actions you can take on electronics waste.
The recycling process: what actually happens to your old phone
11. Modern recycling plants can recover over 25 different materials from a single handset. The process at specialist e-waste facilities typically starts with manual dismantling to remove batteries (which can't go through shredders safely), followed by mechanical shredding, then a sequence of magnetic separation, eddy current separation and chemical hydrometallurgical processes to isolate individual metals. Companies like Umicore in Belgium operate some of the world's most advanced precious metal recovery facilities, processing e-waste from dozens of countries.
What's surprising is how much depends on the phone arriving in good enough condition. Cracked screens, water damage and missing components all reduce recovery rates. The better condition your phone is in, the more of it can be reclaimed - which is one reason why selling your phone while it still has value is the smarter move compared to waiting until it's completely dead.
From the thousands of devices that pass through our platform at OnRecycle, we see this all the time: people holding onto phones for years past the point of peak value, then finding they're worth a fraction of what they'd have got eighteen months earlier. A working iPhone 13 in good condition fetches meaningfully more than one with a cracked back and a swollen battery.

How phone recycling went from nothing to a global industry
It's easy to forget that mobile phone recycling programmes barely existed before the mid-2000s. The first major manufacturer take-back schemes launched around 2004 to 2006, driven partly by EU legislation (the WEEE Directive came into force in 2004) and partly by growing public pressure. Before that, old handsets either went in the bin or sat indefinitely in drawers - the same drawers many of them still occupy today.
The comparison price model that services like ours use didn't exist either. Before aggregator platforms arrived, you'd either take your phone to a high street trade-in kiosk at a fraction of its real value, or navigate a confusing array of individual recycling sites with no way of knowing whether you were getting a fair deal. Our data shows that users who compare prices through sell your phone consistently receive 20-40% more than the first quote they'd seen elsewhere. That gap still surprises people.
What's coming next: the future of phone recycling
12. The EU's Right to Repair legislation, which came into force in 2024, is already changing how phones are designed. Manufacturers are now legally required to make spare parts available for a minimum number of years after a product goes on sale. Apple introduced its Self Repair Programme in the UK in 2023. Fairphone, a Dutch company, has been building modular, repairable phones since 2013 - their Fairphone 5 launched in 2023 with a promised software support life of ten years and replaceable components including the battery, screen and camera module.
Researchers at universities including Cambridge and MIT are also working on hydrometallurgical and even biological processes - using bacteria and fungi - to extract precious metals from e-waste more efficiently and with less chemical waste than current methods. It's early-stage, but the direction of travel is clear: the industry is finally catching up with the scale of the problem.
The honest truth is that the single most effective thing most people can do right now isn't to wait for better technology. It's to stop leaving working phones in drawers. If your old device still powers on, it has value - financial value to you and material value to the recycling chain.
Head over to get a quote on your old handset and see what it's worth today. Takes about thirty seconds. And now that you know what's inside it, you'll understand exactly why it's worth something to someone.
