Dream, Barley and Twang: recycling electronics

[TheVat]

Waste electrical and electronic equipment (better known by its unfortunate acronym, Weee) is the fastest-growing waste stream in the world. Electronic waste amounted to 53.6m tonnes in 2019, a figure growing at about 2% a year. Consider: in 2021, tech companies sold an estimated 1.43bn smartphones, 341m computers, 210m TVs and 548m pairs of headphones. And that’s ignoring the millions of consoles, sex toys, electric scooters and other battery-powered devices we buy every year. Most are not disposed of but live on in perpetuity, tucked away, forgotten, like the old iPhones and headphones in my kitchen drawer, kept “just in case”. As the head of MusicMagpie, a UK secondhand retail and refurbishing service, tells me: “Our biggest competitor is apathy.”

Globally, only 17.4% of electronic waste is recycled. Between 7% and 20% is exported, 8% thrown into landfills and incinerators in the global north, and the rest is unaccounted for. Yet Weee is, by weight, among the most precious waste there is. One piece of electronic equipment can contain 60 elements, from copper and aluminium to rarer metals such as cobalt and tantalum, used in everything from motherboards to gyroscopic sensors. A typical iPhone, for example, contains 0.018g of gold, 0.34g of silver, 0.015g of palladium and a tiny fraction of platinum. Multiply by the sheer quantity of devices and the impact is vast: a single recycler in China, GEM, produces more cobalt than the country’s mines each year. The materials in our e-waste – including up to 7% of the world’s gold reserves – are worth £50.9bn a year...

Will we, I wonder, someday be mining landfills?  Seems to me that whatever does not get recycled and ends up in trash should at least be separated at the landfill into its own dump area, for possible future excavation.

I did read the other day there's a solar panel problem coming in a decade or two: the solars panels will be end-of-life. The numbers are huge.

Perhaps, it was this: Solar panels - an eco-disaster waiting to happen? - BBC News

There was a little discussion about it in the other thread: https://www.scienceforums.net/topic/131667-solar-panels-etc/?do=findComment&comment=1241447

Our local dump ( in London) has a separate section for electrical items. But I don’t know where they send it.
