By recycling toilet waste in this way, no septic tanks, no holding tanks and no chemicals are required. Sun Mar composting toilets do not break the cycle of nature, nor do they have the inconvenience of the old outhouse. Like the compost heap in the garden, Sun Mar composting toilets allow human waste, toilet paper and organic material to break down through a natural process. Heat, oxygen, moisture and organic material are needed for microbes to transform human waste into good fertilizing soil. Oxygen is provided by the ventilation system.
Organic material is introduced by adding peat moss.
The remaining material is transformed into an inoffensive earth-like substance. Because Sun-Mar makes its units out of fiberglass and high grade stainless steel, freezing temperatures will not damage the toilet. The engineered air flow provides a negative pressure which ensures no back draft. The air is admitted through ventilation holes in the front. All of the electric Sun Mar composting toilets that we sell include a ventilating fan to ensure adequate airflow and eliminate odor.
