Peter Arndt, the "inventor" of the dry toilet, developed a new type of toilet bowl that can separate the liquids from the solids. In laboratory tests, the bowl can separate up to the 75% fo the liquids that are aimed to the walls.

This new bowl design, plus the already known eficiency of the dry toilet, allows the liquids to get dried and compacted faster.

In this second version of the dry toilet, the design has been simplified in a way that could be possible to remove the plastic tanks in the bottom of the pit, and maintenance will be reduced to a minimum.
