i'd like to know also.  i asked today @ my pharmacy, and they had no idea.  so i want to pass it on, get something going. thanks. starting a search.

if you check on the bottom of the bottle, you will see a #5 inside the recycle symbol.  this is what i found:   Polypropylene, commonly found in self-sealing containers, like Tupperware, is accepted by very few curbside recycling programs due to its very low rate of recyclability.

How's that for reincarnation?  and more here: http://www.lime.com/features/limes_guide_to_recycling/story/11485/how_to_recycle_everything   striving to be green
