The SUN-MAR SELF CONTAINED TOILET
The key to the success lies in its three chamber design. Each of the three chambers; patented Bio-drum™, compost
finishing drawer, and evaporation chamber, have their own independent environments for optimum efficiency. The
electric version has a thermostatically controlled heater and fan assembly to help evaporate liquid and should be
used where there is a constant electrical supply. The non-electric version is for use where there is no continuous
electric supply, and has no fan or heater.
The Patented Bio-Drum™
Unique to Sun-Mar, the patented Bio-drum™ provides the necessary mass to maintain good compost and allows
easy aeration of the compost by simply turning the drum. Excess liquid will exit through a screen in the bottom of the
drum into the evaporation chamber. Mixing compost in the Bio-drum™ is accomplished by rotating the handle in a
clock-wise direction. Compost is removed from the drum by pulling out the drum lock button and rotating the handle
in a counter clock-wise direction.
The Compost Finishing Drawer
The compost finishing drawer sits below the Bio-drum™ of the toilet. Compost in the drawer is isolated from mixing
with new waste while resting for 4 weeks so that it can finish composting.
The Evaporation Chamber
The evaporation chamber is the floor of the unit under the
compost finishing drawer. This is the area where any
excess liquid will gather for evaporation.
