Sun-Mar
Composting Toilets
 Energistx
brings to you the best brands of ecological technologies for
the home and beyond. Sun-mar leads the industry in reliable,
attractive toilet models in a range of sizes and applications.
Working like the compost heap in the backyard, but without
odor and much faster, Sun-Mar toilets break down human waste
and toilet paper through the natural process of decomposition
without the need for traditional plumbing and water infrastructure.
Because most of this waste is evaporated, only a very limited
quantity of finished compost is produced.
The combination of turning the compost evenly
in a drum simulates the windrow environment, and the fan on
an electric unit or passive venting on a non-electric unit
allows more oxygen to move through the pile when the unit
isn't being turned, without sacrificing the vital component
of moisture.The combination of all of these factors ensures
a rich environment for aerobic bacteria to break down every
part of the pile. It just makes good sense.Oxygen, moisture,
heat and organic material are needed to allow minute natural
organisms to transform the waste to fertilizing soil.
How
the System Works
 •
Oxygen is provided by drum rotation and by the ventilation
system. The drum is easily rotated via a handle at the front
of the unit.
• Moisture is obtained directly from human waste.
• Organic material in the form of peat mix is added
manually, since this organic carbon is absorbent, holds oxygen,
and is cheap and readily available.
• Heat is generated by the compost itself, assisted
by the heating element (on electric models).
• Microbes are contained in the rich top soil which
is added to the compost.
Odor
Free
The
engineered air flow within Sun-Mar units ensures that a partial
vacuum is maintained within the unit at all times. Air is
drawn in 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.
In addition, the tumbling action of the composting drum results
in such a moist and beautifully oxygenated compost that an
aerobic breakdown takes place which is both fast and odorless.
Breakdown is odorless because aerobic microbes produce only
carbon dioxide and water vapor, quite unlike the unpleasant
anaerobic smell often found in a septic tank, outhouse, or
backyard compost.
Microbes
and the Bio-Drum TM
Sun-Mar's
unique Bio-DrumTM has been developed to provide the optimum
conditions for aerobic composting. Using such design, Sun-Mar
has been able to ensure that the compost in the drum is maintained
in the moist, warm, well mixed, oxygen rich condition which
aerobic bacteria need for optimum performance.
Sun-Mar has also found that such approach avoids the anaerobic
activity which occurs wherever there is insufficient oxygen.
This is important because anaerobic activity is slow and produces
offensive odors. The use of this revolutionary Bio-DrumTM
results in composting speeds double those of the old single
chamber units with mechanical mixers.
Start
Up and Use
Sun-Mar
units require very little maintenance. Peat moss should be
added at the rate of one cupful per person per day. Toilet
paper is decomposed easily by Sun-mar units and should be
added as usual. The compost should be mixed and aerated every
third day (or at the end of the weekend) while the toilet
is in use, simply by turning the drum handle and rotating
the drum 4-6 complete revolutions. In cottage use, some composted
material may only need to be extracted in the spring. In residential
or commercial use extraction will be more frequent.

Installation
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 thinwall PVC.
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.
