Portable toilets are needed on every construction site, and in lots of other places too. Generally speaking, though, they are not pleasant spaces. But that doesn't seem to be the case in Switzerland. I just discovered a Swiss company called Kompotoi . They make high-quality portable toilets out of spruce, and they have made a commitment to composting as much human waste as possible.
But the really unique feature that I had never seen before is that each toilet comes equipped with a bin of wood shavings ("litter"), which you are supposed to sprinkle over your poop once you're done. This serves two important functions. One, it dries out the waste which greatly reduces any smells. I can attest that the toilet I used smelt just fine. And two, doesn't it just look better to go into a toilet and see wood shavings as opposed to poop?
This might be an instance of "yeah, only in Switzerland." The retail price for their classic toilet model is CHF 5,966. That works out to about C$9,500 once you covert it to our painfully weak dollar.
