[Greenbuilding] ventilation and urine-diverting dry toilet

[J Daglish]

Try sucking the air out through the toilet bowl... via the flush pipe
if you have one...probably  i legal?

For in wall cisterns a 45degree saddle connection with a vertical
extract pipe nom Ø40mm is made into the flushpipe directly.

This one through the overflow pipe (which you dont have :)

You could put a self closing siphon (a flat plastic tube that uncurls
when wetted to release the liquid .. if think NASA invention)  on the
waste like they do with waterless urinals.
