[Greenbuilding] [BULK] Re: [BULK] Composting toilets

I've never seen any need to separate urine, and my calculations indicated that the pile needed the extra nitrogen to achieve a good carbon/nitrogen ratio. (I was using sawdust)  The Humanure guy agrees in his book - he saw no reason to separate human wastes or kitchen wastes for that matter.  My vote is to save your money and use it elsewhere.

I'm very interested in a urine-separating toilet (a pricey porcelain seat)
which can be connected through the floor to a urine tank at the front and a
bucket at the back. I have been led to believe that keeping things separate
has all sorts of salutary benefits (less smell, urine is a good fertilizer
diluted with water, the composting material in composting toilets can get
too wet, etc.). I'm curious if anyone on this list has personal experience
with these?

I'm also specifically curious how much of an issue smell is with your
composting toilets--of any variety? I get the idea that with a well designed
stack and a tight fitting lid/seat it is fairly easy to reduce this to a
minor inconvenience. I'm not personally offended by the smell of an
outhouse. But I live in a city on 1/12 of an acre with all sorts of finicky
visitors and relatives. Turning folks off to the whole idea by confirming
their misconceptions about the undesirability of such alternatives is not my
goal. If you can speak to how you've dealt with this I'd be grateful.

I have to admit that the cost and simplicity of your $15-$50 versions are
tempting.
