How The BioLet 30 NE Works
If reliable power supply is not an option, the BioLet 30 NE is the way to go. Using a process called batch composting, the BioLet 30 NE can handle a high volume of usage. Batch composting is a process where you make a batch of material then remove it from service so the material can compost without anything new being added to it.
The BioLet 30 NE has a compost cover and ventilation pipes described in the above models, but it works by applying a very different approach. A large compost bin is housed inside the lower portion of the toilet. The toilet is used until the bin is approximately 3/4 full. The top of the toilet is then removed and the bin is removed from the unit and moved outside for further composing. A secondary bin is then placed into the unit for continued operation.
Air circulation through the unit occurs due to the natural convection of air through the ventilation pipe. This is induced by the heat that is produced by the composting process, temperature differentials between the inside and outside of the structure, and by the natural chimney effect created by the vent pipe. Installing an optional 12VDC fan into the vent pipe can induce additional circulation of air and increase the capacity of the unit.
