TerraCycle’s mail-in recycling programs in collaboration with Colgate and Tom’s of Maine are just about the only recycling options available. You can collect your empty toothpaste tubes (as well as old toothbrushes and floss containers) and ship them for free to TerraCycle to be recycled into new products. Large enough shipments can raise money for your chosen school or charity. Alternatively, you could upcycle that old tube into a useful craft.
