If done right, it's the same as a normal toilet, but substitute the "flush" for scooping some sawdust down the hole. I've used quite a few, and if you do it right, you can't smell a thing.
Thanks for the toilet link... That looks really interesting. What do you think of it? Other than that website,I cannot find anything about that toilet anywhere. I'm confused about where the waste goes and how it can have no smell... Is it only for peeing?
Not inside but outside yes if there is no wind/certain air pressure. The toilet has intake air and an exhaust chimney that you put through the roof or a wall. So generally the exhaust should go up like smoke from a chimney but it can also come down at time. It doesn't smell like poo/pee but it does smell something.
At least the model we have at our summer cottage, you can go multiple times while it's still burning since the incinerator and the part where you are doing your business are two separate areas. To "flush" you just press the button that opens the hatch and drops down in to the incinerator.
You have to empty it maybe once month and there is only handful of ash. It's definitely easier to maintain than composting toilet where usually you need to throw in some dry mulch/compost material so doesn't get smelly. Eventually you still have to empty the compost and hope it has mostly turned in to soil. It also smaller than composting toilet so you can fit in inside a small cottage.
I installed a composting toilet a few months ago at an off-grid cabin in the mountains. The important thing to get right is the venting system. This keeps a negative pressure in the compost chamber so air is continually drawn down through the toilet and up out the vent stack. When this is working correctly the bathroom will have no smell at all.
The second thing to worry about is the overflow drain. Depending on temperature and usage, urine may not evaporate faster then it is added. There is an overflow drain to handle this situation. Local building codes may require you to pipe the overflow to a conventional septic system, thus negating a lot of the cost and simplicity benefits of a composting toilet.
Why do people here have such a fascination with toilets?
The way a regular toilet works: Water automatically enters the bowl. You do your thing. You press a lever.
The way an RV toilet works: Water enters the bowl when you press a pedal. You do your thing. You press another pedal. That's my toilet anyway. From the perspective of one's posterior it's pretty much the same thing and you can do all this while sitting on the throne.
Some RVs have flush toilets or even vacuum toilets.
