Today's Lighter TVs Mean Much Less E-Waste

MojoKid writes "We all know that today's flat-screen TVs weigh far less than old-style CRTs, or they wouldn't be able to hang on the wall. New research from the Consumer Electronics Association finds that this translates into a massive savings of electronics waste. The report found that today's flat screen TVs are 82% lighter and 75% smaller than cathode ray tube (CRT) TVs. In other words, 40- to 70-inch flat-panel TVs weigh 34% less than 13- to 36-inch CRT TVs. This reduction in materials has a staggering downstream effect. The report claimed that an old 36-inch CRT TV generated about the same amount of electronics waste as 5,080 cell phones. However, today's 70-inch flat-screen TV generate the equivalent of just 953 cell phones."

What is that in terms of Library of Congress units?

Consider projection systems

Projection systems create even less waste, allow for much larger images, and can generally be refurbished with nothing more complicated than a new bulb.

When my family gathers around for a movie, my 200" diagonal display allows me to include several generations. But the actual display hardware only consumes about 1/3 a cubic foot. The "display" is just wall space, which isn't going anywhere or being used for anything else.

This would be the first device built in the last decade that lasts longer than ones built 30 years ago.

Face it, we're in a world of throwaway electronics. The ancient ones here might remember how our parents sent the TV for repairs every now and then and how we had the same TV from the moment we start noticing that there is a TV 'til about puberty or beyond. Today, you'll be hard pressed to find any kind of electronics that survive 5 years or more.

You know what else creates less e-waste?

You know what else creates less e-waste? Hanging on to your perfectly good older TV instead of buying a newer, bigger TV every time the electronics companies bring them to market. Oh, but let me guess: I bet a 3-D LED TV saves the planet even more than the regular, 2-D kind, right?

Perhaps, but there's other factors to consider. For example, technology improves: I have a 1920x1080 22" LCD monitor or this computer. It is much more useful to me than an old 800x600 CRT or even my 19" 1280x1024 LCD monitor I purchased in 2003 (it's dimmed and gotten a bit yellow over the years).

In addition to improved technology, a lot of newer devices use considerably less resources to manufacture and operate. The electricity costs of running a CRT monitor or TV are much greater than that of an LCD monitor or TV of comparable size. I'm not sure about plasma, but I don't have such displays here.

Yes, there's a lot of e-waste and people should definitely waste less, but there are several compelling reasons to upgrade equipment over time.

Yes, it's an unfortunately naive question, but the persnickety answer is that the white LEDs that form the backlight internally have phosphors to generate broad-spectrum light.
