I'm new to the Permies forums. So hi!
The very first topic I came across was this one and I just had to laugh.
My personal solution puts me in neither category 'A' nor 'B'......or maybe both?
(Either way, I'm on the 'edge', lol).
My rented place has a septic tank which I do my best to avoid using.
In my laundry room (so, ok, it's technically indoors, but it's right next to the back door) I've placed a commode chair - the type that many elderly and disabled people use -
which is where I pee.
It has a conventional toilet seat, so it's comfortable and there's no issue of splashies, and a removable plastic bucket with a lid, so also no smellies.
When it gets half full I dilute it with some laundry water (which I collect in a bucket from each wash) and add it with the paper to the compost/kitchen-scraps-disposal-system.
I bought the commode chair for a few dollars from a charity shop. They are in plentiful supply (at least where I live) so, yeah, no new materials are needed.
