The town of Agbogbloshie in the west African country of Ghana has been called a digital dumping ground. Millions of tons of discarded electronics wind up there annually, so people can try to recover anything of value. It’s therefore one of the most polluted places in the world, because workers burn plastic coatings to get at the metal in the guts of gadgets.   
 
But Agbogbloshie is about to get cleaner, thanks to the opening of a new facility for handling such e-waste. Four machines that can strip plastic will prevent the burning that produces hazardous smoke.
 
E-waste is a large and growing problem thanks to the large and growing appetite for electronics. Responsible recyclers exist, but too much e-waste still ends up being exported and improperly disposed of in places like Agbogbloshie.
 
The worst e-waste remains batteries. The most common type, lead-acid batteries, are classified as toxic waste once used. And more and more rechargeable lithium ion batteries are finding their way into landfills and other unsafe disposal sites.
 
But the problem of e-waste can be solved with proper recycling. The new machines in Agbogbloshie should be able to strip enough wires to produce about 10 metric tons of copper a month. That's good news for livelihoods—and lungs—of local residents.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
