"I'm sure that in a recycling context the glue can be undone with either heat or a chisel." Every decision impacting recycling has to be viewed with labor cost

"I'm sure that in a recycling context the glue can be undone with either heat or a chisel."
Every decision impacting recycling has to be viewed with labor costs factored in.
Virtually every recycling victory we've seen in the corporate sector in the past decade or two is due to efforts to make the recycling process cheap enough that the loss is negligible (and in the best cases, recycling is even profitable).
Nobody is saying that gluing things together makes them completely unrecyclable, but that glue could easily be the difference between a recycling company actually recycling parts vs throwing them in the landfill due to increased costs blowing the economics of recycling out of whack (if cost of recycling is significantly larger than cost of throwing item in the landfill, the item is almost certainly going in the landfill).
This is exactly the situation EPEAT was set up (as mentioned, with Apple's input) to watchdog over, and Apple is clearly now putting spectacular hardware design above any green/recycling factors. Whether or not that is a terrible thing is a personal choice to make, but you seem kind of fanboyish in your efforts to pretend like Apple's decision is somehow EPEAT's fault.
Accept that you prefer computers that are now actively non-recyclable and move on.
- jws 14y agoThat's 40 cents worth of scrap aluminum. I'm not seeing a plausible argument for labor rates making it landfill.
- ars 14y agoIt's far too dangerous to put either heat or a chisel anywhere near a Lithium ion battery. So, yes, it's completely unrecyclable.
- jws 14y agoDepending on the chemistry lithium ion batteries are safe to up to 400°F or more. Surely the manufacturing engineers pick a thermo adhesive with a melting point between the maximum operating temperature and the maximum safe storage temperature. Think about the iPad 2 screen glue. Glass glued in place, but a hair dryer is more than enough heat to release the glue.
- ars 14y ago"Depending on the chemistry" is not a valid answer when recycling something - they don't have time to lookup the specs of each battery. http://batteryuniversity.com/learn/article/lithium_ion_safety_concerns http://batteryuniversity.com/learn/article/lithium_ion_safet... says maximum temperature of 265°F, which is very very close to the temperature needed to melt the glue (250°F, for low temperature glues, and 380F for high temperature glue - which is very close to even your 400° number.)
