It would be interesting to capture a number of definitions for an "EOL product" from different category of researchers. Will EOL mean different to different people / researchers depending on their area of expertise / research?
Dear Mangesh, did you got any further with your question yet?
As you mention in your question, I believe that EOL has a different meaning depending on who you ask. Legally, if an EOL product is considered waste like in Europe, this is owner dependent. ("any substance or object which the holder discards or intends or is required to discard"). The leagal perspective, however, does not necessarly work with the function perspective which Carlo brought up. I can discard my television even though it is still working perfectly (It's becasue no one wants my CRT any more so I had to throw it away in order to make up space for my new 100 inch flat screen TV...)
In addition, the food packging for example might still be used by the same owner for the same or another function (soda bottle used for carrying water. I regulalry see tourist do that in southern Euopre where there are public drinking water sources). However, this might include some kind of modification, which in turn might be considered as a new life cylce hence the first EOL was reached. And there are probably many more thoughts about this around...
I haven't made up my mind yet to chose one single EOL definition, I might never do?! But I'd like to listen to more opinions on this, hope this discussion didn't end before it really started.
