I have a camp toilet (plastic bucket and comfortable seat) with a set of waste bags that once formerly stated that they could be tossed in normal trash,  I don't believe their current products make that claim anymore but state "dispose of properly," which kind of dodges the issue.  Frankly, this makes the trek to the camp facility that much more appealing.

Still  a camp toilet is very handy.  I keep one around, especially against the day when the Big One shakes us awake, damages the plumbing, and we are on our own for a time.  I live in southern California, can't you tell......

Camp toilets are useful in other situations as well
