Something I've learned from other like-minded individuals is to just CALL! Most products, if not all, have their 1-800 numbers listed somewhere on the label - you can ask them how their items can be recycled. Also, I'd recommend calling even if you know it can't be recycled. Why? Because it lets them know that we ARE consciously thinking about the packaging that our products come in, and that we're basing their decisions, accordingly. If their sales drop - it won't be long before they start making significant changes. All times I've called - they have been deeply concerned that I, a consumer, will stop buying their product unless they alter their packaging. We actually have a lot more power than we think.
I also like to call companies out on their green washing - they need to know they're not fooling anyone (well, most of us).
