Anybody had experience with these

EnviroPro Australia - cheap, affordable, quality Natures head composting toilet australia Natural waste and odour treatment products including composting toilets (http://www.enviropro.com.au/wastewater-treatment-products/waterless-composting-toilets/mobile-use/natures-head-composting-toilet)

I have read a few comments online, no smell, no chemicals, waterless....price aside they look a good option.

has to be vented externally,, uses peat moss??

I'm not sure what the rest of you lot do inside the toilet,,
but ours is quite a pleasant place to be,

where do they get the idea lack of smell is a selling point?

Only ever heard good things about them, but never used one, although I have been looking myself at this option. I believe Spudboy has one in his truck and has very good things to say about it.

One of the biggest benefits is how long they will go between emptying them. As well as the no smell bit...

The biggest drawback is using one requires knowledge of how it works - ie using the pee container so as not to get any in the compost mix, but that's only minor IMO.

Cant understand why they cant cope with urine.I would be adding compost worms to the tank,they will make the system work even faster.I use compost worms in my vegie garden,amazing creatures.If you get their conditions ideal they consume mountains of organic matter and turn it into a rich fertiliser.

A friend has installed two at different properties he's owned over the years and loves them. He thinks septics are primitive by comparison.
You can get them powered or unpowered, waterless or flushing, vented or unvented. They produce garden fertilizer.
Be aware that some councils insist on inspections for some composting toilets, which from what I can gather are unnecessary and just a way for the council to collect a fee for doing nothing useful, so check that out.
I'm seriously considering a Sun Mar one for our studio extension at Maleny. The $2600 approx. cost would be a fraction of the $10,000 cost of expanding the existing septic system, which needs a major overhaul, although it still works. Just need to do more research about our particular situation.

The one I linked is the smallest version to be installed in the defender.

The pee causes a couple of issues - it makes the compost too wet and fills the tank up too quickly and it also causes the compost to smell. The jug that catches the urine just unclips and empties where ever every couple of days.

Fair enough,I guess the tank on these units is quite small too.
I have a 800lt tank my worms live in.Must do a post in the gardening area.After many different attempts,this one is the best sofar.

No experience with them but reading the info in the link you posted (thanks!) - they seem like a well thought out bit of kit.
I recall showing my better half a camper build with one fitted - may well have been Spudboy's - but got a quite negative reaction at the time. She's much more positive now after having a read of how they actually work and has less of a vision of a bucket of poo sitting in the back waiting to turn into compost!!

With ~80 uses before emptying the compost it works out to over a month of full time use for two people. Makes it a much more attractive emptying regime than for a normal chemical toilet and being able to dispose of the waste without seeking out an appropriate dump point etc would be a bonus.
I'm guessing practically it would be even longer than a month as most of us take the opportunity to use the loo at fuel stops etc (as long as they are in a habitable state).

Other than the cost (probably about twice the price of a decent chemical loo in a caravan), I wonder why they're not more generally used? Guess its likely a perception thing?

We have friends who are greener than green.They built a straw bail house,off the grid too.They have solar and batteries.
Their toilet is a compost/worm driven unit.No smells at all and it takes anything dropped down it including kitchen scraps.It does have an extraction fan to draw air thru it to ensure no decaying poopie smells enter the house.Castings used in the garden.
