I have an answer about the non flushable but disposable options, as well as a wash and reuse option.
The first, the dust bin. Duh. As we say in the states, like Mexico. Pipes in MX aren’t large diameter, and in places where infrastructure is just patched, all TP goes in a waste basket. Brilliantly smart. No having to think, “does this flush?” because the answer is always, “no, you idiot.”
