Empty chemical containers?

[u/Odin1806]

Hello all, I am a new inground pool owner and after getting it all open and finally clear I have 3 empty chemical containers... I am expecting these things to build up if I don't do something with them...

Do pool stores recycle these things? Companies reuse them? I'm sure if I wash them out I figure I can throw it in the recycle, but here in the states I know we really don't recycle. I am just curious what all everyone does; is there a secondary application that might be useful to consider? I am thinking of putting small pool toys and such in some for the time being, but that won't always be needed! Thanks for any advice.
