Our composting toilet system works well.
There is no smell, it is a joy to use and there is little effort involved in maintaining it.
I've just received a compost thermometer so we can now monitor how well the heap is doing.
My only regret is that I put in septic tank, percolation area, pipework, plumbing, flush loo etc etc etc bloody etc ten years ago when I could have saved so much money, hassle and worry using this system.
Sigh. You live and learn.
We now say things like, "gosh I was caught short when I was out today and had to use one of those antiquated flush loos - terrible experience" and (to guests) "you have a choice - you can use the old-fashioned water closet or the far superior composting toilet; don't be shy" or some such nonsense.
I have a prissy sister-in-law visiting this weekend who is not aware of our 'modernisation'. Could be interesting.

Update
Thought I'd give folks an update on my 'system'.
I have now dumped three loads of wood chip and poo into my compost bin. In as much as I can see what happens to it, it is slumping fast, which I take to be a sign of decay as well as settlement. It has been colonised by wood ants, which is fine with me.
I've added a box and toilet seat to the original bucket, which makes using it much more enticing. Still no smells or other issues. The only issues I have had are to do with mismanaging one bucket of my wood chip supply before bringing it indoors, as a result of which it has a few tiny flies.
It is gratifying to see how quickly the compost pile is growing compared to how quickly it grows if I only add plant material from gardening. Obviously, it is the wood chips that are doing most of that work but they are there because I have a reason to gather them and put them there. And fortify them with nitrogen before I put them there.
Separately, I noticed that the area in the garden where I peed through winter (and continue so to do) is the one area of hard-packed clayey-sandy soil that is supporting large plants (mugwort, nettles, one of the goosefoots, feverfew). They stand out as a dense island of tall, vigorous plants in what is otherwise a sparse mix of dandelion, deadly nightshade and the occasional birch seedling. One has to conclude that my pee has wrought a miracle!
These results have convinced me to install a separate urinal in the house when I eventually buy/build a house. I think the case for the power of collecting pee is overwhelming.
Poo less so but there are other reasons for keeping it out of flush toilets as all here know, so I will continue to collect it.

Re: Update
Isnt nature wonderful? Ive noticed this effect before in the dried up moats of castles and old country houses. Hundreds of years of pee and poo out of the garderobe into the moat producing a high nitrogen soil particularly attractive to nettles.longjohn wrote: Separately, I noticed that the area in the garden where I peed through winter (and continue so to do) is the one area of hard-packed clayey-sandy soil that is supporting large plants (mugwort, nettles, one of the goosefoots, feverfew).

I've just discovered one of the joys of compost loos. I'm sure plenty will be written about kenneal's poo palace, but I had the pleasure of filling it to the point where the next person to sit down would have had a rather messy experience. I had a great time compacting the contents of the bucket with a piece of wood . Roll on the day when I can have one of my own! Sorry I didn't take a picture .
If you want to go one better than just composting and are feeling keen, you could build yourself an anaerobic digester. Advantages - it provides methane to boil your kettle from the anaerobic methanogen bacteria that do the work, and all the nasty aerobic pathogens that might be in the pee and poo get killed off.JohnB wrote:I've just discovered one of the joys of compost loos.
This process is used in sewage farms. I saw one in action a long time ago - a self powered reactor, the methane evolved used to heat the reactor to provide an optimum operating temperature. A simplified version is widely used in Chinese rural areas.

Well...
I finally got my brother in law and my sister in law's fiance on board with regards to buying some farmland together in Normandy. Between us, we should eb able to buy cash somwhere about 150 acreas Once bought, I will be taking a year out go go over and split into three dwelling units and to get the land in to basic shape.
Hopefully we will have found somewhere and I will be beginning the work on it before Xmas.
Composting toilet included of course....
Finally, I feel like I am actually doing something
Once bought, I frankly couldn't give a sh*t what happens to it's exchange value in fiat terms.
My family's ticket to the future will have been secured (at least as far as that future can be secured)

Did anyone see this in Friday's Guardian - http://www.guardian.co.uk/environment/2 ... .recycling - ?
Says that 68% of sewage sludge in the UK already applied to fields supplying 3,000 of 146,000 farmers with savings on fertiliser of £450/hectare. Positive in one aspect, but not great percentages really are they - 68% supplying only a small fraction of farms?

It should be good stuff but unfortunately the way things work here, often the sewage gets mixed up with industrial effluent before being processed. There are ways and means of re-extracting the most serious heavy metals (Lead, Mercury etc) before selling/giving it on to farms, but that doesn't mean it's perfect.
