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.

Don't leave it in your car during a Texas summer :-)

60C is 140F.

This temperature it easily attainable inside a vehicle left out in the hot sun all day.

They must be thinking of an average finnish summer or something... For example, this years summer in most parts of central europe has seen temperatures that will definitely exceed 60°C inside a car.

I sense alot of people going ballistic on Nokia when this hits the market.

Conclusion: When it's hot, dont buy Nokia stock!

as far as im aware the temprature in this years heatwave topped out at 36C. Now it would get hotter in the car but only by 10C, that leaves some 14C at least.

Granted its a little close, but i seriously doubt a car would reach 60C even if left out in the sun all day. Certain parts of the car interior would melt at 60C.

Don't forget that this is 60C rather than 60F (not to you Griswold, but rather to others who might get confused).

In Northern Cali it has been a 115 in the shade and in a car it could easily get that when in the sun it easily is breaking 120.

I live in southern New Mexico, where the summers days usually top out at about 105-110 F. I keep a thermometer in my car, and that thing has reported 140+ F on several of these such days. And that was in the shade....

I live in the Okanagan up in hottest part of Canada. It is generally about 30-45~ here in the shade in the summer. That means 60 should be quite easy to get in a black vehicle with no tinted windows in the sun, but I see this as a gimmick not worth getting anyways so who cares?

Umm.. what's the point of having a phone if you leave it in the car?

I personally know a lot of people who leave their cell phone in their car to keep it plugged in to charge it. The idea is that they only need it when they go out, and they always take their car.

I agree -- what's the point to a cell phone if its left in your car all the time. But in any case, on a hot day with the sun beaming into your car -- the temperature in the car will be well more than 10 degrees hotter....of course it depends on the interior and color. My car black leather interior...right about now it'll easily be 20 degrees hotter in the car than it is outside. I've seen the temperature (my car has digital temperature readout for both inside and outside the car) in my car hit 130 F already. 140F is definitely well within reason.

No, that's not hot enough! Automotive electronics for the passenger area of a car are specified to operate up to 85ºC (underhood is specified up to 125ºC).

I was going by Nokia's commentary:

quote:
The required temperature for the disassembly is 60-150 ºC. If it were lower the phone could dismantle by itself, for instance in a hot car, and if it were higher the plastics would melt.

Well, 60-150ºC is a wide range, but clearly they can't have the phone "self destruct" below 90ºC. I'm sure Nokia is well aware of this, however.

You honestly believe that Nokia is making a "self-destructing" phone and didn't think about hot cars etc. I would quess that you need to apply a fairly large amount of heat to a one specific part (via laser etc).

That's silly, the idea is to make it easy recyclable, not by a university lab but by small organistaion that handle waste, imagine if they had to place each phone in a specific position and use a directed laser, then it would be easier and cheaper to use screws wouldn't it?

I agree btw that 60C is too low, not just cars in summer but near a heater in winter too.

No lasers? Funny I thought this was in the article...

Non-removable battery?
By Lord Evermore on 7/29/2006 8:39:30 PM , Rating: 2
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.


Perfect!

Now when the batteries explode, whole phone will fall apart, spilling firey blobs everywhere instead of being one mass that fuses together to slow down exposure to air.

60c is easy

ESp in the desert, if your a solider with a cell phone in the deert 140F inside of a car is quite normal.

60 - 150 is a POSSIBLE range of values
By a1trips on 7/30/2006 8:26:02 PM , Rating: 2
None of you geniuses is even considering the fact that the process might be tweakable so it only triggers at 150 plus temps.
Course you DO NOT have similar examples in FOOD( chocolate ),metals ( steel softening points) or in a dozen otehr fields.
makes you think.

Check your phone manuals
By GaryJohnson on 7/30/2006 12:06:46 PM , Rating: 2
From a Motorola Manual:
"Never expose batteries to temperatures above 45°C (113°F)."

From a Nokia Manual:
"Always try to keep the battery between 15°C (59°F) and 25°C (77°F)."

From a QTEK Manual:
"Do not leave the product or its battery in places where the temperature may exceed 60°C (140°F)."




Dell and Nokia share technology!

Hm, anything that melts and isnt pure cannot be said to only melt at 60C. if it is set to do that, a matter of time at a lower heat will also make it soft enough to pop as well.

i foress 130 degrees, the temperature of a car after 3-4 hours in sun, easily working at this seal.

140 is also possible in mid summer all day long scheme.

however, if you have a battery in the heat for that length, you are quickly killing your phone anyways (as well as being an idiot). still, this does truly sound like a DELL waiting to happen :)

It might take them two minutes to dismantle a phone using traditional methods, but with a very traditional method (a large hammer) I can do it in two seconds already :)
