60秒科学:Better E-Waste Handling Helps Environment and Health


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

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.
