Many people will have heard of compost toilets as a method of greener living. However, you may not know that composting toilets are classified into two types: self-contained and central composting toilets.
Both, however, have the same goal: to kill germs and recycle our urine and human waste without requiring water. Instead of flushing, the waste is sent through a pipe to a composter, which is concealed from view by a trap door or screen.
They don't appear to be all that different from your conventional toilet. Composting, self-contained toilets are typically seen in cottages or for summer residential use. If more than two individuals are utilizing the unit, it should not be operated all year.
As the name indicates, the toilet and composter are integrated in one unit, so composting occurs just beneath your toilet seat.
However, there's still al lot to evaluate when it comes down to a self contained composting toilet. In this article, we will go through the ins and outs of a self contained compost toilet in comparison to the central system.
For a long time, the only toilets that many people knew about were those with an external waste tank. These are known as "wet-flush" systems. They have a number of disadvantages, but they are still the most common type of toilet in use today.
In the United States, self-contained toilets are not yet a necessity. But for other parts of the world, they provide an affordable and sustainable solution to sanitation needs. In fact, more than 1 billion people worldwide live in places where there is no toilet at all! Self-contained composting toilets have been used in many developing countries since 2005 as a means to address this problem without breaking the bank.
Self-contained toilets differentiate from central systems in that they are a single, self-contained unit. Central systems are made up of two major parts: the pedestal and the chamber.
Because self-contained composting toilet units are all-in-one, they are ideal for traditional houses which are built on concrete slabs or dwellings with no underfloor room, or boats.
These toilets are typically put in homes that have space beneath them. The composting chamber is located beneath the home, the pedestal is located above it in the bathroom, and the chute links these two components.
The chamber with a centralized system is generally a full level beneath the toilet itself.
Centralized composting toilet systems offer more capacity, are usually more costly, and are most commonly utilized in office or commercial buildings.
However, once installed, they require less frequent care and only need to be emptied roughly once a year. AlasCan, Clivus Multrum, CTS, EcoTech Carousel, Phoenix, and Sun-Mar Centrex are popular systems, with costs ranging from $1,400 to more than $10,000 depending on the system's capacity and intricacy.
There are both electric and non-electric options available for central composting toilets.
This makes it a more costly composting process, yet a convenient and easily maintained option.
Below are some Central composting toilet systems along with their prices, tools and features.
The Sun Mar Centrex 3000 composting self-contained toilets can accommodate 6 adults or a family of 8 on a regular basis at home, or 9 adults or a family of 11 on weekends and holidays.

The rotation of the Bio-Drum in a continuous flow system pushes compost along the drum before it drops automatically into the collecting container (50 liter) at the end of the unit.
