Automatic Aeration
Automatic Aeration™ is the Key
Santerra Green Systems are the most advanced composting toilet systems available today. A patented Automatic Six-Way Aeration™ process is what differentiates Santerra Green from others.

In short, this process speeds up the composting and evaporation process significantly through forced-air, heat and natural microbe-action. And, unlike others, there is no drum to manually turn.

About the Composting Process
Composting is simply nature's method of renewing and preserving itself. In nature, decayed organic material, whether plant or animal, gradually decomposes and becomes either water or enriched soil, very much like your garden compost.

But, the ongoing preservation of our precious lakes, rivers and streams is a problem that both ourselves and our children must accept responsibility for. Most conventional toilet systems such as septic tanks were not developed with the environment in mind, so they are often a major cause of unnecessary pollution.

Santerra Green help nature's proven method by reducing and recycling waste into natural compost, while using little or no water in the process.

What is waste?
Almost 90% of all toilet waste is water, the balance is organic material.

Where does it go?
A large percentage of the water portion of waste is evaporated through a vent to the outside, dramatically reducing the waste, which is then recycled into natural compost.

How does this happen?
The continuous action of aerobic microbes makes this happen. Periodically, a small amount of peat moss (standard, garden variety), and optionally, additional Compost Accelerator is added.

When do you empty it?
As little as once a year using the built-in Rake Bar (the bottom bar on the front of the Santerra System), the recycled waste is raked down into a collecting tray and a small amount of natural compost is emptied into your garden, completing nature's cycle.

Is "turning" necessary?
Some claim that turning the waste, like in a drum, is necessary. But, this is simply not the case.
