Re: Composting toilet
I looked at a Nature's Head toilet. The urine goes into a plastic bottle, the poop drops into a bin with some peat moss, and in theory, it gets broken down.
Very limited stuff to dump out. The urine bottle can be emptied on a toilet or another sanitary source.
No water needed, so no need to worry about winterizing.
In theory, the poop bin can be emptied out as dirt.
It appears messy to empty out the poop bin.
You have to have bags of peat moss to kick-start the chemical reactions and replace them every time the bin is emptied.
The fact that I've not seen spare parts, so if the urine bottle leaks or the poop bin breaks, that may be expensive.
Instead, I wonder about just a European style cassette toilet as a compromise.
