All major types of dry composting toilets are approved by the 
Health Department in Western Australia. These include the two
major types of Clivus Multrum, the Dowmus, Rotaloo, and the 
Biolet. Some homemade DIY ones have been approved as well. 

Most operate on deposits falling on a slope which spreads them,
to allow evaporation and oxidation. Anaerobic bacteria and other
beasties die, and after a period of time, and some movement down 
the slope and over the retaining bar, dry, sweet smelling garden 
compost is available. The angle of the slope and the height of 
the "bar" are critical.
