what is the correct recycle thing to do with the empty ink carts that come
out of copy machines, the ones that held toner, (they are usally 10 to12 inches long) they are stacking up in my classroom, I couldnt let
them just throw them in the trash knowing they will never break down. I
also have empty ink carts from the large laser printers.
