E-Waste and Where Old Electronics Actually Go

The world generated a record 62 million tonnes of electronic waste in 2022 — an average of 7.8 kilograms for every single person on the planet — according to the UN's Global E-waste Monitor, the most authoritative tracking effort on this specific problem. Only 22.3% of that mass was documented as formally collected and recycled in an environmentally sound way. The other roughly 78% didn't simply vanish. It went somewhere, and where it actually went is a more specific and more troubling story than "landfill."

The Scale, and Why It's Accelerating

E-waste generation grew 82% between 2010 and 2022, and it's not slowing down — the same UN monitoring effort projects the total will reach 82 million tonnes by 2030, a further 33% increase from the 2022 figure. That growth rate meaningfully outpaces the growth in formal recycling capacity: documented formal collection and recycling did grow over the same period, from roughly 8 billion kilograms in 2010 to about 13.8 billion kilograms in 2022, but that's growing far more slowly than the waste itself is being generated, meaning the gap between what's produced and what's properly processed is actually widening year over year rather than closing. The right-to-repair movement covered elsewhere on this site is, among other things, a direct response to exactly this dynamic — a device that's uneconomical or impossible to repair gets replaced instead, which is precisely what's driving both sides of this widening gap at once.

The Wealth Actually Being Thrown Away

Before getting to where discarded electronics physically end up, it's worth being specific about what's actually being lost, because the framing of e-waste as purely an environmental liability undersells a genuinely striking economic fact: this waste stream is also, quite literally, one of the richest ore sources on the planet by concentration. A tonne of discarded circuit boards can contain gold at a concentration roughly 100 times higher than a tonne of freshly mined gold ore — in some high-grade estimates, as much as 800 times higher — because manufacturing concentrates trace precious metals into circuit pathways and connectors far more densely than any natural gold deposit does. Put in dollar terms: globally, the raw materials embedded in a single year's e-waste are valued at roughly $91 billion, and current recycling efforts recover only about $28 billion of that — meaning roughly $63 billion in recoverable gold, copper, silver, and other materials is being lost annually, mostly through incineration, landfilling, or the kind of inadequate informal processing covered below. At a smaller, more concrete scale: an estimated 642 million smartphones currently sit unused in drawers across the European Union alone, collectively containing around 8.6 metric tonnes of gold and other recoverable materials worth an estimated $1.26 billion — sitting completely idle, neither recycled nor in use.

Where the Uncollected Majority Actually Ends Up

The formal-recycling gap isn't evenly distributed globally, and the regional difference is stark: Europe's documented formal collection and recycling rate sits at 42.8%, while the same figure for African countries is under 1%. That gap exists partly because a real share of the waste generated in wealthier countries is legally or illegally exported to lower-income countries in the first place, often under the label of "used equipment for reuse" rather than declared waste, a categorization that in practice determines which regulatory regime, if any, actually applies to a given shipment.

Ghana receives an estimated 15% of the world's e-waste, much of which ends up at Agbogbloshie, a site in Accra that has become one of the largest informal e-waste processing hubs in Africa and has been documented as a serious pollution hotspot by multiple independent research teams. The processing methods used there are informal by necessity rather than choice — without industrial equipment to safely separate valuable metals from the plastics and cabling surrounding them, workers burn cables and components outdoors to strip away the non-metal material and access the copper and other metals underneath. That burning process releases lead, cadmium, chromium, nickel, and arsenic directly into the air, soil, and water of the surrounding area, and peer-reviewed research has documented measurable health effects — including cognitive effects in children attending schools near the site — among the people living and working in the immediate vicinity, not just the workers directly handling the material.

Why This Keeps Happening Despite the Value Being Lost

The uncomfortable economic logic underneath all of this is that the $63 billion in unrecovered material value described above isn't evenly capturable — recovering it safely and efficiently requires industrial-scale processing infrastructure that's expensive to build and operate to proper environmental and safety standards, while the informal alternative, however hazardous, requires almost no capital investment and provides real, if extremely dangerous, income to people with genuinely limited alternatives. That's not a justification for the status quo — it's the actual structural reason a wealth-generating waste stream keeps flowing toward the processing method least equipped to safely capture that wealth or protect the people extracting it, rather than toward the formal recycling infrastructure that could recover more value while causing dramatically less harm in the process.
