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!

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. Thatís 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.

                            has saved to date!

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 itís getting scarce. So scarce that we canít 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.
