Spain has a hard time figuring out how to get their sewage system to handle regular toilet paper and many regions/places require you to deposit the toilet paper in trash cans next to the toilet. That being said, I think there are better options like a clever public awareness campaign, banning the claim of being flushable, required packaging that says not to flush, requiring to be packaged with plastic bags for disposal, or even just accumulating all the costs of issues from the wipes and charge them to the industry as a whole in various taxes and fees, which will push the incentive to solve the problem on the industry.

I used to use wet wipes and flushed them, now I have a bidet and have only ever used wet wipes when traveling, where, ironically, Spain’s issues with basic things like flushing toilet paper, make disposing/not flushing wet wipes easy because many bathrooms have a lidded trash can next to the toilet/in the stall.

Ironically, their bigger issues produce a solution to a different, bigger problem.

Note: Yes, I’m aware it’s not everywhere in Spain or only Spain, but I am curious to hear where everywhere everyone has encountered having to put their toilet paper on a trash can instead of flushing.
