I agree that the present accepted systems for waste disposal are not
always safe. They could be, maybe. Refer to my statements to that
effect in my last message. Ideologically I feel the concept of waste is
a major culpret in the whole dysfunctional reliance upon traditional
treatment systems. composting toilets offer a way to break this notion
of waste and view our excreta as a wonderful resource.
I did realize that Hal was probably not an avocate of the pit privy,
however I did use his statement to launch into a debate that we feel is
needed and worthwhile.
The hydrogen sulfide question is as Hal states, mostly at low enough
concentrations to be of no noticable effect even in the pit privy
situation (unless its inside an airtight structure). However it is a
concern inasmuch as we don't know the health effects of longterm, low
Finally, the pit privy can be an advancement to other methods of excreta
disposal such as the nightsoil buckets directly to vegetable garden
method which is employed throughout parts of the world. However there
are other methods that provide a more decent quality of life to
populations who choose to use them.
