Environmental Benefits
By using a Sun-Mar composting toilet you are doing your environment a huge favor.
- You are protecting your lake and ground water from being polluted by pathogens and
nutrients
- You are saving huge amounts of water
- You are recycling the nutrients directly back to the plants they came from.
No other way of handling human waste can compare with a Sun-Mar!
The lake you could be saving!

Excel, Year Installed: 1998
Where Installed: Alleghany
National Forest,PA
"Thanks to the Sun-Mar Excel unit I
was able to obtain a sewage
permit and begin construction on
our cabin in the Alleghany National
Forest. The Excel model was
approved as an alternative to a
septic system. We have used the
Excel model for four years and are
very satisfied with its performance."

Excel, Installed 1999
Installed in cabin near Crystal
Lake, Laramie County, Wyoming
We installed the Excel unit in
November of 1999. Since the cabin
is without plumbing, the Excel was
and is ideal. It looks good and
everyone can use it without a
problem. It has serviced a large
group (12) on a given day and is
odorless. We are so glad we found
this system, otherwise we would
not have purchased our
"get-a-way".
TESTIMONIAL

Protecting Your Lake or Ground Water
..Toilet waste is over 90% water content. Sun-Mar evaporates this liquid and carries it back to the atmosphere via the vent system.
Depending on the model, a Sun-Mar can evaporate up to 2 gallons per day. That’s a lot, when you consider there is no flushing
water to bother with. By evaporating liquids, your Sun-Mar is ensuring that no pathogens or nutrients escape to pollute your lake,
river, stream or groundwater. Zero output means zero pollution.
..Regular toilets allow pathogens and nutrients especially potassium and nitrogen to pollute your water. This will gradually kill your
lake by fostering weed growth and so removing dissolved oxygen.
Nothing can beat a Sun-Mar when it comes to preserving the environment.
Saving Water
..Water is our most valuable resource, and in many places it’s getting scarce. So scarce that we can’t afford to be flushing it down
the toilet. Because many Sun-Mar models use no water at all, a Sun-Mar saves a huge amount of water.
..A four-person household using a traditional 3.5 gallon flush toilet will flush some 70 gallons per day down the toilet. This works
out to an annual volume of over 25,000 gallons per year. So far we calculate that based on our mix of residential and seasonally
used units, Sun-Mar has saved a massive 3.2 billion gallons of water up to January 2008, a figure that is increasing by an amazing
6,103 gallons each and every minute.
Nothing can beat a Sun-Mar when it comes to saving water.
Recycling Nutrients
..Waste is mostly made up of moisture, and complex organic molecules. These molecules contain plenty of carbon and hydrogen
atoms. In a Sun-Mar, aerobic bacteria work to break these molecules down by converting the hydrogen to water and the carbon to
carbon dioxide. Both are vented to atmosphere along with the moisture
..The small amount of remaining materials are largely oxidized salts which are collected by a Sun-Mar in the finishing drawer.
..This is a valuable resource which is ideally suited for uptake by plants, and constitutes less than 3% of the original volume of the
waste.
By recycling in this way Sun-Mar returns the nutrients to the plants they came from.
