Between 1971 and 1979 Sun-Mar entrepreneur Hardy Sandberg developed and improved on the first composting toilets making them one of the most effective human waste management programs that utilize eco-friendly methods to save on water and ensure proper reuse of human waste in a safe and effective means.
Over time Sun-Mar have developed these waterless toilets that makes use of little-to-no water, making them very eco-friendly. They utilize the managed decomposition by aerobic means or the aerobic processing to decompose the human waste in its chambers.
There are two types of composting toilets, the self-contained and the central toilets.
In composting toilets the human excreta is churned alongside peat, saw dust or even coconut coir that ensure the odour is kept at a down low and the absorption of liquids during the aerobic processing is effective.
Some of these off-grid toilets utilize external composting steps to facilitate the bacterial breakdown of the waste. These types of toilets are common in many European and Far East countries that are keen on environmental conservation and effective water use.
Most of the water in the waste gets to evaporate into the atmosphere leaving behind well churned manure for use as a natural fertilizer.
The process of composting toilets simply harness the natural process of natural decomposition but manages it under proper decomposing conditions to ensure the most effective conversion of waste by regulating the amount of moisture, organic content and heat in the process.
This process ensure that all pathogens and are broken down leaving behind only nutrient rich organic content for your fertilizer needs.
Sun-Mar the premier composting toilet manufacturers since the 1960s developed the three chamber composting toilet systems which has proven very efficient and proper in the aerobic composition.
The first chamber is the composting chamber which is usually a cylindrical chamber with a handle for rotations. This chamber ensures control and regulation of oxygen, moisture and manages the aerobic breakdown in an effective and timed method.
Fitted with 110 volt electric models with a thermostatically controlled heating element, the evaporation chamber which is the 2nd chamber ensures that excess moisture drains out and evaporates.
This chamber can be removed and cleaned through the opening on Centrex 1000 and the 2000 units while the same can be done on the Centrex 3000 unit through the drawer access port.
The 3rd unit also known as the finishing drawer contains two removable and interchangeable compost finishing drawers. The first of the two interchangeable units is placed inside the collection housing unit while the second is located on the side the unit.
The composting is complete when the waste is moved to the second drawer and isolated from fresh waste and allowed to dry. This dry compost is odorless humus that is free from viruses and pathogenic materials and ready for use on plants and flowers.
