There was a discussion on bikejournal about reusing old tubes...I know many of us have found uses but another option is sending them to Splaff, a company that makes sandals from recycled materials.
I'll add the information to the wiki herehttp://www.bikecollectives.org/wiki/index.php?title=Splaff%2C_Inc.linked from the shop recycling pagehttp://www.bikecollectives.org/wiki/index.php?title=Shop_Recycling .
