Typical waste entering the toilet is over 90 percent water. The composting cycle evaporates the waste water and which is carried back to the atmosphere through the vent system. The remaining small amount of solid material is converted into a useful fertilizing soil by natural decomposition. The correct balance between moisture, oxygen, heat and organic material is needed to ensure a rich environment for the aerobic bacteria that transform the waste into fertilizing soil. This ensures odor-free operation and complete decomposition of waste.




When you consider that the average American uses 7,665 gallons of water (that’s approximately 2,400 cases – 24 count – of bottled water) each year just flushing the toilet, it makes you wonder about an alternative.

Important Note:
When human waste is properly composted, the end product does not contain any pathogens or viruses (these are destroyed by bacterial breakdown). This nutrient-rich fertilizer can then be used on plants or around the base of trees, as part of the natural cycling of nutrients, reducing your need for commercial fertilizers and preserving local water quality. It’s recommended that the fertilizer be used on non-edible gardens & plants.

The 3 important processes a composting toilet must perform:

Compost the waste and toilet paper quickly and without odor
Ensure that the finished compost is safe and easy to handle
Evaporate the liquid
Composting Toilet Manufacturers

Sun-Mar, is the forerunners of the composting toilet industry since the 1960’s. Different manufacturers have tried different methods to achieve these goals, but none has proved as efficient as the Bio-drum, designed by Sun-Mar. In their design all three tasks/processes require independent chambers, this isolates each step into its own separate environment. This revolutionary three chamber approach is incorporated into all Sun-Mar units.

Natures Head
The toilet is self-contained, urine diverting and the waterless operation allows for ease of use for many applications. The Nature’s Head is lightweight, odorless and compact making it a perfect fit for your home, cabin, tiny house, RV, workshop, boat and survival application.
