Tea Tins

You know, Earth Day was a couple of Sundays ago, and it occurs to me that the little tins I get from Adagio would be great to recycle somehow. Maybe they should make the containers out of aluminum so we can recycle them easily. Maybe they could take them back? I wonder how much it would cost...It seems a shame to have to throw them away. I know I solicited feedback on Teachat.com (?) and people just said they use them for other things, but I think that's unsatisfying. The tea tin I have from Twinings is the same way: it's beautiful, and should be recyclable somehow.
