How the Rota-Loo Works
Composting is nature's own recycling process, it is how organic material is broken down by micro-organisms to produce a rich product called Humus, an organic fertiliser, mulch and soil conditioner made from decayed organic material.
Inside the Rota-Loo are six bins located on a turntable. When a bin is in use it is located directly below the toilet pedestal and human waste, toilet paper and bulking material is added to the bin. A ventilation system ensures moisture is drained away and evaporated to keep the solid waste dry and warm for optimum composting.
When a bin is full it is rotated to the next available bin and allowed to compost for at least 12 months, after which the humus (decomposed organic matter) can be emptied into a garden as fertiliser.
Rota-Loos fan forced ventilation system provides a slight negative pressure at the pedestal to ensure any odours (which are minimal if its all working correctly) are drawn away from users.
Some people think that all composting toilets smell. This is definitely not the case with the Rota-Loo system.
The smell that one normally associates with sewerage or septic tanks is actually caused by anaerobic bacteria. These are formed when too much water or liquid is mixed with urine and faecal material. The Rota-Loo is a waterless system where natural moisture is drained and evaporated so it is designed to maintain aerobic decomposition and not produce odour. A low cost Bio-Stimulant can also be added to the composting mass to help the aerobic activity and control odours.
As a further safeguard the ventilation fan ensures air is continually being pulled through the Rota-Loo to the vent, creating a negative pressure at the pedestal. This means that a small amount of air is always being taken from the toilet room... keeping it nice and fresh.
