Doesn't anyone know?

I don't know either, but I will give you an idea. Maybe you could call your local waste management type service and ask. If so, I am sure they could tell you where to take them. I know the plastic part would be recyclable, the problem is I am not sure about the magnetic tape.

I would call up your local thrift stores and see which one wants them. I'm sure they would go and you would get a tax receipt for the donation. Are they empty? If not you might make sure there isn't anything on them that you don't want others to hear. I have purchased empty ones at my local thrift store.

I couldn't find anything on the internet. But you can submit environmental questions to this email. Maybe they can give you an answer. earthtalk@emagazine.com Here is the website that I found the email at http://environment.about.com/od/earthtalkcolumns/a/recycleplastics.htm Sorry I couldn't find you an answer.

Hello youdontsay, In fact I also wonder whether they are recyclable or not. Like you, I have boxes at home and I don't even know what to do with them. I am not going to throw them if I know that somewhere, somehow, near my area I can just send them to a recycle center. Fortunate for me, they are all music tapes that I collected when I was just a teenager. I don't even have a cassette player at home or in my car! I think the best that I could do right now is just to let them stay there in one of the rooms...

DUUUUUUUUUUUUUUUUUUUUH put it on Ebay and sell them one by one!
