Don't have this problem often (yet), but was so disturbed at the odors and obvious health hazards associated with disposing of poopy diapers. Really, these are toxic biohazards, as are baby diapers, but doubt the hazmat teams will come out and collect our soiled diapers and paper towels.
This is the solution I've come up with so far, however just on a diaper at a time solution. Here it is.
Get two layers of plastic bags into a waste bucket so you'll have two bags ready to help seal odors. Buy a lot of that super absorbent cat litter, perhaps with odor control. Put a few cups into the bottom of the bag. After removing and flushing large pieces, put the diaper into the bucket with poop showing (don't fold diaper over) and pour cat litter over all poop to absorb the moisture and odors. You can continue putting in wiping clothes, and pouring over more litter as needed. Seal up the inner bag. Pour some baking soda over this inner plastic bag to help cut odors, then seal up the outer bag.
These are great to have when you are taking an elderly parent out for the day and now have the responsibility for making the adult diaper change, the bags allow for quick and easy disposal - which is great - I leave a few handipacks in my car
inexpensive item well worth it -when you need it
It also feels better knowing that I am not taking this explosive toxic mess to my garbage can to foist surprises at me the next time I open the lid. Especially in hot weather. WHEW.
Anyway, this was explained in the original post connected to the question, and not the explanation doesn't show.
The procedures for cleaning up a sewage or vomit mess in a public place is like a hazmat crime scene. There are kits available for restaurants, hotels, malls with crime scene tape, biohazard marked plastic bags, etc. They have a solution that effective kills all bacteria, so they are then allowed to toss it in the garbage. But what do WE do with this stuff?
"Sunshine Cleaning" movie has a lot of info on the impact of biohazards. And it's a nifty movie.
But more important, why does the OP comment disappear? From now on if I post a new comment, I'm not going to the "more infor" for the headline, but straight to the comments area. Weird.
Good Will or a used children's store might have one at a good price.
Put kitty litter into the bottom of the bucket or box. Place dirty diaper face up, then pour on more litter as needed, add soiled paper towels, latex gloves, etc. Add more litter to cover poop stuff (perhaps enough to place next diaper face down into the litter). Layer the soiled diapers and kitty litter until the box is full, adding more litter if the box is smelly.
Between uses, twist the inner plastic bag closed, and put on the lid. When the bucket or box is full, twist inner bag closed with twisty tie, add some baking soda for more odor control. When bucket or box is full, seal up, perhaps mark SOILED DIAPERS!! on it and dispose in garbage can.
Suppose one could do this with urine soaked diapers as well, though many of them have odor control.
