Yes it is.

One thing important to take into account in the life of a device is what happens when it's thrown out.

A friend of mine works at an electronics recycling facility, and with regular desktop or laptop they're able to take them apart to scavenge some rare metals, separate inert materials like cases from dangerous ones like the battery.

That's much more costly for Apple products because of how they're integrated, so they end up not recycling much.

Doesn't Apple recycle them for you if you trade them in?
