MullToa Works with Nature
MullToa unites the natural composting process with advanced Swedish technology accelerating and optimizing biological decomposition, evaporating excess liquid and exhausting odours … all within an elegant bathroom fixture that is easy to use and economical to operate.
The closed-system Mulltoa's are fully automatic electric toilets that anticipate your every move! Sitting on the toilet seat opens the trap doors; closing the toilet seat lid activates the stainless steel mixing mechanism that efficiently breaks down paper and distributes moisture into the compost material in the upper chamber. Material in the upper chamber is finished in the lower chamber and eventually emptied into a garden composter. The non-composted portion and the dry, composted portion are kept separate.

A fan circulates warm air under and around the compost for fast decomposition and evaporation of liquid. A float switch operates and addtional heater (MullToa 60 & 45) if excess liquid is detected. Once a week or as needed, mulch is added through the toilet seat opening.
Using efficient Swedish technology electrical consumption is very low with an adjustable thermostat, which is set according to the number of people using the toilet. When you are away for more than two days, just turn your MullToa off!
