I'm sure guys would have seen one of those water-saving urinals that uses biotechnology instead of water to "clean up" liquid waste. I've always been curious about how it's done exactly, but apparantly it's a trade secret or something, and all I've found was that microbes are used (obviously) to clean up uric acid (well, duh). You don't need a Ph.D

Anyway, I am still doubtful about this flushless urinals. I mean they still have to "settle" the urinal wall....

How they settle the urinal wall is one of my first problem I thought about as well. But it seems to be working though. NIE has been using it for a long time.
