Well to try and answer all questions....I did this also as a kid way back in the day (saved up and donated to a local hospital) and from what I remember, they use the aluminum from the tabs to make a machine or something?? Not 100% sure but what I can do is definitely get a correct answer from my coworker so I have an accurate answer. I really do appreciate the response though on this thread
Stay tuned, I will get an answer tomorrow when I get to work and post it in the evening.
