Composting Toilets in your Motorhome

[Moose Mobile]

Just reading the van specs on the Consort Motorhome website and I see they are offering a composting toilet as an option when buying. Is this becoming a thing? Are any other makers offering composting toilets as standard items?

We’ve a OGO composting toilet in our van, the solids in effect end up in a bucket 1/2 full what looks like garden potting compost. There is agitator that mixes it all up drying out the solids. As it is all dried out there is no residual smell and the total volume of after a few weeks is surprisingly small & it just gets added to our garden compost heap.

For us it’s a great no hassle solution.

Surely you could achieve the same result at zero cost by pissing in the sink. I'm sure simple arrangements could be made for short men and ladies.

Yes would work,
Oh a small problem!
How to empty a cassette full but no liquid?
Answers please.
Couple of suggestions:-
Spoon
Gloved hand
Sure we can think of more!

Well that works if you don’t use your van or toilet very much.
We need to empty our solids every 5/6 days.
If we don’t it needs to be compressed but that only helps for a couple more days.
But then it could be our fibre rich diet!

After my bowl cancer op in 04 I had an ileostomy bag fitted for a couple of years until they decided I might beat the odds and did a reversal.
Emptying was never a problem, sat at the back of the toilet seat, lean forward and emptied it straight down the toilet.
The contents are like a thickish soup, it's only with a colostomy bag you get real poo.

At the newark show this year there were a couple of vans with separating toilets installed as standard. Can’t remember the make. Be interesting to see the situation at the NEC.

Saw them as either optional or standard in some of the more “upmarket” (expensive) 4x4 PVC’s.

I watch 'Foxes Afloat' on YouTube, they had commissioned a canal boat fand had one of those loos with the agitator paddle ... they had to add coir to the mix for it to work properly and mentioned that if they didn't get it right could be a bit 'fudgy'! When they were having their next canal boat built they'd spec'd a normal cassette toilet as it was less hassle than trying to keep 'fudgy' happy!

“Fudgy” is pretty much the original state of the material being processed, isn’t it? So ew… that’s all I need. And presumably bound together by coir?

Just for you Minxy , the Stanford Paediatric version of the Bristol stool chart. I like it. Much more fun than the original! https://share.google/images/uteRJ7jLcCy5Yun5S

I think I’m closer to getting it now. Some of these products are possibly aimed at the underserved coprophiliac market.

What happens to urine?

They use a waxed liner in the toilet. This holds the urine long enough for it to be incinerated just like any solids. The slight issue with lots of urine deposits burnt is a different residue left on side of ash bowel, easily cleaned with a soak in warm water.

 

[Jays2]

Incinerated urine , you mean boiled dry!
You can’t burn a liquid by product.
Or why would you burn a solid?
Bag it and bin it, just like picking up dog waste and putting in a bin!
This is what I don’t understand about people who S.it everywhere and walk away, just pick it up, bag it and bin it.
Then as a further example of behaviour, you can always spot a women’s piss spot, they leave behind a tissue to wipe their lady parts ! Then leave it behind to indicate to other women this is the piss spot just for you.
What they forgot is guys pick these up and sell them on the dark web!
You are dispossessing your DNA!

The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day).20 Aug 2023

If alone!

Have you ever boiled a pan dry?

And the smell!

I visited the Centre for Alternative Technology (CAT) in Wales about 15 years ago. Their public toilets were separator toilets, the urine went straight to feeding tomato plants while the solids were collected in well ventilated holding tanks, when they opened the access point they use to empty the solids, we were invited to take a 'sniff' .... due to the forced ventilation there was no smell whatsoever... It was like a giant SOG and when it was full, they left it to dry, aided by the forced ventilation. They then emptied it using a tractor/digger and put it into a large holding area for a few years so it broke down naturally and then used it for compost. They had several holding areas working on a rotation system.

This is the conversion I made to turn our standard Thetford toilet into a separating toilet to extend our emptying time when off grid.
A simple plastic plate that drops into place and a bowl with plastic bag liner to catch the number two's, nothing exotic, just a simple solution.

Much cheaper to just pump it in the nearest river, like the sewer companies do.
