Shenanigans. Most of the time, with the more recent developments, most ears cannot tell the difference.
But to respond more meaningfully to the original question:
It'd be an interesting exercise, at least, to determine what the failure rates would be for components harvested from old electronics, vs. new - and see whether the labor and energy inputs necessary to harvest those parts and to QC them would be any less than it is to manufacture new ones - and further, to examine the undesirable outputs in the form of carbon emissions and other pollutants. Some manufactured goods are not made the way they used to be made because they were more environmentally unfriendly than current options. See, e.g., the elimination of Freon as a refrigerant in the USA.
As a separate issue, a lot of what is marketed as "green" technology is simply stuff that uses less fossil fuels or generate less carbon emissions
in the hands of the consumer . See, e.g., hybrid vehicle technologies (which rarely if ever mention energy and material inputs attendant upon such things as manufacture of nickel-metal hydrides and other materials unique to their manufacture). Without claiming to have an informed opinion on the objective green-ness of such technologies, I'd suggest there's a fair amount of snake-oil being sold among the legitimate environmentally sound stuff. Certainly, in the USA, viable alternatives to dependence on foreign oil are desirable, but the public has proven highly resistant to real change such as willingness to enact public financing for mass transit, and then USE the mass transit constructed thereby. But what many Americans have done -- believing they are doing the environmentally friendly thing -- is to buy into a version of eco-friendliness that lets them own 2 cars per family, and so on.
All of this is of course more complex than I can hope to discuss meaningfully on an internet forum, and in any case, I realize I've veered into territory that is perhaps more political than this forum's charter permits, so excuse the drift...
