Composting toilets have been around for many years, yet there are still plenty of misconceptions about what they are and how they are used. These toilets are useful when you live off the grid or if you want to reduce your home’s water use. They are also commonly used by people who own RVs or own a lake cabin that doesn’t have indoor plumbing.

All You Need to Know About Composting Toilets
If you don’t know much about composting toilets, you are probably imagining something similar to an outhouse or port-a-potty. That is definitely not what these toilets are.
A composting toilet can turn solid waste into useful compost. This works by creating an oxygen-rich environment that allows aerobic bacteria to break down the waste.
There are two designs of composting toilets. Self-Contained and Central, or Remote.
Self-Contained Composting Toilet
A Self-Contained Composting Toilet is one that contains its own composting system. A compost chamber is often positioned beneath the bowl.
These toilets are commonly found in RV’s, tiny homes, boats, or any place a person may reside without indoor plumbing. They are also found in seasonal lodging homes such as cabins or summer cottages. While most are designed for temporary use, there are some models that can be used in a residential setting.
Central or Remote Toilets
With a Central or Remote composting toilet, the unit directs waste to a central composter that is located in another part of the home. This could be in the basement or in some cases, outside. A large enough central system can easily connect to multiple toilets, allowing this type of compost toilet to be used in large homes that have several bathrooms.
How Do Composting Toilets Work?
There are three important variables that all composting toilets require to function correctly. These variables are moisture level, carbon-nitrogen balance, and temperature. Both self-contained and central composting toilet systems have to establish and maintain a specific level of moisture. They also need the right temperature and carbon-nitrogen balance for the bacteria to grow, thrive, and compost the waste.
You will need to have the right amount of moisture for a composting toilet to work as it should. Too much moisture will drown out the aerobic bacteria needed to compost the waste. It’s important to keep the compost moist, but not wet. The process of reaching this precise level begins with how the toilet deals with liquid waste.
The most common method is to divert the liquid waste into a separate container that the owners much empty out. There are some composting toilet models that come with a container to use. And there are also models such as those made by Sun-Mar that can evaporate liquid waste. However, you will still need a container or drain pit to use as backup for this type of toilet.
A composting toilet will also draw moisture from solid waste. This process involves using a ventilation system that constantly circulates air using a fan. This type of system can help reduce the volume of the compost by as much as 95%.
The proper disposal of liquid waste helps decrease the event of nitrogen buildup in the compost. However, you still need to add in materials that are rich in carbon to balance the carbon and nitrogen level. Some materials that you may want to add include peat or coconut fibers.
Getting the Right Temperature
To keep the aerobic bacteria alive, you will need to keep the temperature of the compost within a certain range, typically between 60 and 100 degrees Fahrenheit. There are some manufacturers of compost toilets who will help take the guesswork out of getting the temperature just right. Their toilets include features such as sensors, thermostats, and automatic mixers.
