In a nutshell...
No.
Theres hardly any Ali in it, the foils covered in oxide, theres too much other gunk in there and it'd cost more to convert the Ali oxide back into Aluminium in a arc furnace than its worth.
Plus all the enviromental stuff........

The smelters make a metric ton of Ali per day per cell, in rows of 50, about 10 rows per smelter.
From Alumina that costs US$350 per ton and its 99.998% pure Ali.
That then gets made into capactors......
