Description
Our Green Loo GT 120 waterless composting toilet system has a special capacity to compost due to its capillary floor. Our Green Loo GT 120 is designed to ensure optimal levels of moisture, temperature, oxygen, carbon and nitrogen required to achieve good composting are present in the chamber. Moisture is managed through a drainage and evaporation system which removes excess liquid from the solids. Excess liquid evaporates through the ventilation pipe or is dispersed via a gravel filled dispersal trench.
Certified to Australian/New Zealand Standards 1546.2:2008
The Green Loo GT 120 composting system incorporate an unique and ingenious capillary tray at the bottom of the chamber, allowing for drainage when there is excess moisture in the compost and re-hydrating the compost through capillary action (like a self-watering flower pot) when the compost is too dry and requires extra moisture to optimize the composting process. Moisture is managed through a drainage and evaporation system which removes excess liquid from the solids. Excess liquid not evaporated is dispersed via a gravel filled dispersal trench.
The Green Loo GT 120 waterless composting toilet has a capacity of 120L. With an adequate number or spare containers, the Green Toilet has unlimited capacity. When the container is nearly full, it can be either emptied and returned or replaced with a spare container. The waste can then be left to decompose either inside the GT spare container or in a separate composter. Wheels make it easy to move the tank. For all year round use, the GT can be equipped with a heat conductor.

Maintenance
Every few months to a year the Green Loo composting toilet chambers will need to be rotated/exchanged. No official training is required to carry out the rotation.
If the toilet is used consistently by the same number of people, you will soon see how often the ‘In-Service’ chamber needs to be replaced as this is dependent on use.
You can purchase any number of compost chambers in a package but the minimum is two. You can either upgrade to the three chamber model when you first purchase the system or buy a third chamber at a later date.
A sufficient number of chambers must be purchased to allow the out-of-service chamber a minimum time from the time they are disconnected from the waste chute.
Every few weeks you should shine a torch down the toilet pedestal to see if it is full, (when the compost pile reaches the top of the internal vent pipes). This is not as bad as it sounds since the pile will always be covered with sugar cane mulch and toilet paper.
When the ‘In-Service’ chamber is full, you will need to swap it with the ‘Out-of-Service’ chamber.
To exchange the chambers:
- Disconnect the chamber(s) from the liquid drain and ventilation pipe
- The compost pile in the Out-of-Service chamber should have reduced in size to about 20% of its original size and contain a maximum of 75% moisture. This ‘humus’ must then be disposed of as per the local health department regulations. This normally means placing the humus under 10cm of soil or other plant based compost.
- Unscrew the flexible vent pipe from the compost chamber
- Close the liquid drain valve and disconnect it from the base of the chamber.
- Unstrap the lid of the chamber and lift it up the waste chute.
- Slide or roll the chamber on the trolley to one side and immediately put on the lid from the emptied Out-of-Service chamber. The lid contains an insect-screened air intake cap to allow circulation to continue.
- Depending on the model this full chamber is either connected up to the liquid drain and ventilation system beside the In-Service chamber or is capped with insect-meshed breathers and left in an airy and sunny spot on the property to compost.
- The empty chamber can then be placed into position under the toilet pedestal, the chamber lid lowered and the flexible vent pipe and liquid drain hose reconnected leaving the liquid drain valve in the open position
