Does sound interesting. I wouldn't have thought it would compost at a rate to stop smells. And what do you do when you empty it.?
Yes it is the same brand as what Kimberley use (Natures Head). Kimberley made me aware of compost toilets which sparked my interest and a heap of online research gave me the confidence to give it a crack. After all the research I couldn't find a better quality unit that would suit the space and application. It is designed so when used in a shower recess that the water won't go in and the seat stays dry and size is very small.
When I say no smell I really mean it. The three of us (2A 1C) used it for four days and I could stick my head in the bowl with flap open with no offensive odour. Just popped my head in again tonight to verify my response to you after a day of the camper being locked up and again no difference.
This couple have a heap of good info in the youtube vids to get you started if genuinely interested -

- Sewerage is the result of mixing 1's & 2's. Keep them separate and you are a large way there.
- 1's are basically sterile for up to 48hrs. Empty the 1's every day or other day and you can tip it over established trees (supposedly good for them), tip it down the drain whatever. We didn't seem to have any odour from this either but a teaspoon of sugar into the 1's tank sorts that if you do.
- The real nastys in 2's will die of in between 6-8 hours. So just wait half a day or more from last use before emptying. You should get your hands dirty when emptying though. No liquid sewerage to splash around as it sloshes out at the dump point!
- 2's go into the compost which starts life as a $2 from bunnings coir peat brick mixed with 3L of water. This will last in excess of 80 'motions'. So you only empty every 5-6 weeks when using full time or for us I am anticipating about 4 months.
- The longer you leave the compost the more it breaks down so keeping longer isn't a bad thing.
- When you empty it you can put over the garden (not eating plants advised) or put it in a rubbish bag and into any bin which will be my preferred option. You can also just dig a hole and bury it if in the bush though I can't see why you would do that as it doesn't take much forward planning to empty before going offline for an extended period. I am not lucky enough to be away from work for anywhere near as long as it will last.
- No flushing! Just a couple of turns of the handle after use and no water used except for the initial 3L when starting a new compost.
