Because of the variability of use, people and location, it’s impossible to give ‘hard and fast’ figures, but as a guide, we would expect the GT 120 container to provide the capacity of 200 – 220 ‘solid’ uses. The GT 330 container has a capacity of around 800 ‘solid’ uses.

The realised capacity depends on many factors, such as the ambient temperature, frequency and density of use (once composting kicks in, the mass will reduce in size, providing additional capacity), the amount of toilet paper used, and the amount of wood shavings or sawdust added. The urine use is unlimited as urine is both used in the composting process and evaporated, with any excess being passed out as leachate.

More leachate will be discharged in winter/cooler temperatures as the composting process will slow down.
