While some stores and businesses have cell phone recycling stations to drop off your old and worn cell phone which is then taken to a facility to be shredded or physically dismantled, Nokia is looking to a new method that could be more cost effective. Through research done at the Nokia Research Center in conjunction with three universities in Finland, is showcasing a prototype cell phone that can be disassembled by applying heat which then separates the various components of the phone to make them easier to recycle. From Nokia:

The idea is to disassemble a mobile phone by a heat-activated mechanism without any contact. By using a centralized heat source like laser heating, the shape memory alloy (SMA) actuator is activated, and the mobile phone covers are opened. The battery, display, printed wiring board (PWB) and mechanical parts are separated and can then be recycled in their material specific recycling processes. The required temperature for the disassembly is 60-150 ºC.

Nokia goes on to say that takes on average two minutes to dismantle a cell phone using traditional methods. With its new process, the company cuts that time down to two seconds. And for those of you worrying about your phone falling to pieces while sitting inside your hot car, don't worry. The 60C threshold for disassembly should be well above their average temperature of a car left in the hot sun all day.

Non-removable battery?

Conveniently for sales, this also sounds like the phone can't be taken apart for repair, and even the battery may not be removable.

What's wrong with having a pinhole that you shove a screwdriver in, and the phone pops apart? Sounds cheaper than buying specialized equipment in order to be able to disassemble Nokia phones.

Kind of like those old star wars speeder bike toys, press the button on the back and all the parts blow off of it... Might be that the mechanics to do this limit the size of the device, or that said mechanics would be too vulnerable to breakage...

If you leave a normal phone in the car through a hot day you might expect parts of it to stop working by the way... It's like a video tape or CD, don't leave it in the car it friggin melts!!

I am actually guilty of this. In my old Isuzu on a 109F texas summer, I lost a bunch of cd's and a cell phone that was on the dash of my car for a good 8 hours. My fishing tacklebox (in the trunk) required tools to be opened.
