Composting toilets convert human waste to fertilizing soil. Sun-Mar uses a unique three chamber system, each with its own independent environment for optimum efficiency.
The composting drum is the first chamber, where the compost is kept moist and warm. Peat moss and kitchen scraps are added to the drum to keep the compost working. The second chamber, the finishing drawer, is the third chamber, is where the liquids are evaporated and carried away by the exhaust stack. On electric models, the thermostatically controlled heating element and fan speed the process.
The self-contained units are available in three sizes. Central composting units, where the compost is separate from the toilet, are made in two sizes.
