I think they do give some consideration to that. For example you can send any Apple device back to Apple, or drop it off at one of their stores, and they will recycle it. In the U.S. at least, they will send you a prepaid shipping label to ship it.
And if that doesn't happen, and the machine ends up in a landfill, that's where their standard list of "made without arsenic, lead, etc" can help. In terms of the shell, aluminum and glass, while energy-intensive to produce, are arguably more benign substances to have in a landfill than plastic.
