These systems are small, waterless systems that can be placed in existing houses, marine locations, Tiny houses, vacation homes and other locations where there is low to medium use.
However. it is important to note that these are not “composting toilets” as such, just commodes, where the toilet is a temporary holding facility and composting must be carried out in a separate composting area. This could be composting tanks like the ones used for garden compost, or a open composting pile.
So you need both the “composting toilet” listed below and a composting area for the full system.
With the use of compostable bags, the contents could be disposed of at a municipal sewage treatment facility, but that defeats the idea of a composting toilet, although it does still offer water saving benefits.

KAKAPO COMPOSTING TOILETS
Manufacturer – ADVANCED EPOXY FLOORING
Country – NEW ZEALAND
System webpage – www.kakapos.net/
System Type – Dry – Compact – Remote Composting
Summary – The Kakapo is a horizontal drum type composting toilet that is designed for partial to full composting in the unit depending on the use.
With the use of a family of 5, the system requires 2 week cranking and removal of the material for “finishing off” of the partially composted contents in an outside composting pile.
Cabin and occasional use will only require 6 month yo yearly extraction and in this case the contents should be fully composted. The drum is located outside the building and rotating the drum with the crank hane when required, moves the composting waste to the rear for extraction.
The main advantage of the system is its ability to be used in locations where you cannot have a basement to go down to such as a concrete slab house. Sitting at normal toilet seat level it does requires a small (350mm) excavation where the tank sits external to the slab. If this is not possible, the system can be sat on the floor, and a step up to the seat is required. A rotary vent is used for air flow and liquids extraction to a container for reuse in fertigation or drained to an outside treatment pit.
A simple and effective system for installing to an existing house.
