Peter is at least partly right. However not all wastewater treatment plant sludge meets a happy end, I am a sanitary engineer, I know. And I would think that you could usually find ecologically suitable places for the solids, but it might be a bit of work and not always possible. I do like the idea of composting, but not sure I would ever actually do it myself. Hard to imagine it would truly be smell free.
I also like the toto idea, spray is cleaner and probably better for the environment than TP. I have hand held bidet sprayers in my home. Anyone ever do this in an AS?
Let us know where you end up!
