I expect no one treats it as contaminated. It goes in the trash or is spread.Definitely valid points dwh. Even if you adhere to treating 3-4 week old compost as contaminated, there is still a huge difference in mobility and freedom and length of stops at RV dumps:
I hate to think of fixing/cleaning a broken incinerating toilet. A composting toilet isn't going to break significantly, and is less complex. I can understand preferring an incinerating toilet, but it doesn't extend off-grid time compared to a no energy composting toilet or a hole in the ground.
I was close to ordering a vacuflush, but I've pretty much turned 180 degrees and thinking about low odor simplicity. When poo and technology combine I don't want to be the repair man.
