Composting Toilets: How it works: Oxygen

Installation | Moisture | Oxygen | Temperature | Pathogens

Micro-organisms that require oxygen to survive are called aerobes. Organic materials are decomposed most rapidly by aerobes ~ much more rapidly than the anaerobes used in septic systems.

Aerobes need many cubic metres of oxygen per day for rapid breakdown. A small ventilation fan in the Nature Loo supplies up to 420 litres of air per minute, more than enough to keep the process going at optimum levels. This has the added advantage of acting as a highly efficient extractor fan to remove rising odours from the toilet room.
