Composters & Toilets

Sun-Mar Composting Toilets

Composting is Nature's Way

Every living organism consumes nutrients and creates waste. To transform waste back to nutrients and complete this cycle, nature uses the processes of decomposition and evaporation. As is often the case, nature seems to be doing business in the best way possible.

That's why Sun-Mar toilets are designed not only to harness these natural processes, but to optimize and accelerate them.

Toilet waste is over 90% water content. This can be evaporated and carried back to the atmosphere through the vent system. The small amount of remaining material is recycled into a useful fertilizing soil.

Wherever there is a poorly working septic system, a Sun-Mar can take care of the toilet waste; where there is an outhouse we offer the luxury of an indoor facility; and where there is no toilet at all, a Sun-Mar provides the right environmental choice. Sun-Mar units are economical, quick to install and easy to use.

Because no chemicals and no septic systems are used, fragile environments can be protected. A Sun-Mar composting unit is an environmentally healthy choice for recycling human waste.

The Sun-Mar system produces no pollutants, while collecting nutrients. With a Sun-Mar, recycling is made easy!

Odor Free

As well as ensuring an aerobic breakdown in the Bio-drum, Sun-Mar ensures an odor free environment by engineering the air flow within the unit to maintain a partial vacuum at all times. Air is being drawn in either by a fan (or on non-electric units by the vent chimney) over the evaporating chamber and up the vent stack. Not only does this evaporate excess liquid, but by continuously pulling air in we ensure no smell escapes from the unit.

Evaporation is assisted on electric units by a thermostatically controlled heater in a sealed compartment underneath the evaporating chamber

Vent Stacks

The main task is the installation of the vent stack, which is included with all units. The vent kits included in the shipping carton are sufficient for installation in most single story buildings. If more is needed they are normally easy to find. All vent pipes are thin wall PVC. For more vent stack installation information, Electrical

All electric units are supplied with a power cord and plug which connects to a standard (3) pin 115 Volt outlet and powers both the fan and heating element. 12 Volt fans for non-electric models can be installed in-line with the stack, and connected to a battery which draws from an alternate source of energy, such as a solar panel.
It is recommended that all units be installed on a GFI (Ground Fault Interrupt) circuit to protect your unit from power surges.

Drains

Electric units include ½ emergency safety drains. These should be connected if heavy use, residential use or power outages are anticipated. NE (Non-electric), AC/DC, SPACESAVER and Sun-Mar Mobile units are all fitted with 1 drains, which should be connected to an approved drain pit, container, or other facility.

Winter Use

SUN-MAR units serve as a reliable year-round facility when prepared for continuous or periodic use during the cold winter months. If you use your cabin only once in a while in the winter, the unit may be used as a holding tank during this time. If your SUN-MAR will be in use every weekend in the winter, or in a residence, the temperature must be kept above 55o F at all times to keep the compost going. 

Please note all composters, toilets and rainhogs must ship truck freight. You may continue with checkout and we will contact you to confirm price before proceeding.
