Electronic Waste on the Decline, New Study Finds - 0 views
-
the total mass of electronic waste generated by Americans has been declining since 2015
-
The biggest contributor to this decline is the disappearance of the large, bulky cathode-ray tube (CRT) televisions and computer monitors from American homes,

“If you look at the state laws that exist in many places for e-waste recycling, many of them set their targets based on product mass,” she says. As the overall mass of e-waste declines, meeting those targets becomes more difficult. Moreover, says Babbitt, the main goal of these regulations had been to keep electronics with high levels of lead and mercury out of landfills, where they can eventually leach into the surrounding environment. But these days, a more pertinent concern is how to recover elements like cobalt (used in lithium-ion batteries) or indium (found in flat-panel displays). These elements aren’t as environmentally toxic; rather, they are relatively scarce in the Earth’s crust, so failing to recapture them for reuse in new electronics is wasteful. “The e-waste recycling system is somewhat backwards-looking,” says Babbitt; it has struggled to keep pace with the changing nature of electronics.

This article highlights how the way we need to look at E waste needs to change overall. As discussed in E wasteland and here as a topic wee TVs and monitors based on CRT technology which has basically disappeared at this point from the waste stream. Since regulations in the past have been based largely on the overall mass of the waste and now that newer technologies have less mass than older ones regulations and recycling requirements need to be rethought. It also focuses on the newer challenges with new technology being based on rare earth metals and the need to recover them more efficiently and reuse them instead of mining new virgin materials.
