Quoting Amelia Margaret:" How do you dispose of them? We recently moved to a house with a septic system and I am seriously grossed ... [snip!] ... am seriously grossed out by not being able to flush them. What is the non-grossest way of disposing of them if you can't flush?"
get one of those trash cans with the metal spring loaded push flap that you can put stuff in but it snaps back shut

wrap it up in tissue paper and toss it in.. theres really no other way if you dont want to put it in a plastic bag and take it outside EVERY TIME you change it.
