How Does an RV Composting Toilet Work?

Composting toilets work by turning your waste into compost. This helps in encouraging and increasing the activity of microorganism already present in your waste.

Composting toilets make use of no water, and only needs a dry medium such as peat moss in order to control the smell and to provide the carbon which the waste needs to start decomposition. Furthermore, in these toilets, your urine and feces are divided and held in separate holding tanks. Similarly, they are also emptied separately as well.

When these tanks are full, urine can be dumped in the toilet, and the composted waste becomes safe to dispose of along with the other trash without any extra treatment. The compost can further be used as a fertilizer; however, some rules and regulations forbid the use of human compost, so it is a good idea to check the regulations first.

Characteristics of our Favorite Models

Before investing in the best composting toilet for your RV, it is important to take a look at the top features present in these products. Mentioned below are some things you should consider when searching for these toilets.

Size and Usage

When investing in these toilets, you need to keep in mind that toilets for multiple users are made of tougher materials and come with a large waste tank. This is because if you overload a small toilet, it can create stress and unwanted odor, causing the life expectancy of the component to decrease. Even though there is no exact formula to decide which toilet you must buy, you should search up the expectancy of the product you are buying.

Also, if there are more than four people using this toilet, then invest in a medium or large size one instead of a small one.

Easy Installation

These composting toilets are very easy to install and are self-contained. In fact, installation should not be a deciding factor when investing in these units. However, there are certain features such as handles and vents mounted on both sides that make these units very helpful to pick up and use. Moreover, it is a good idea to buy a product that has tech support available readily along with an instructional video as well.

Ease of Cleaning

These composting toilets are not difficult to clean at all. However, the quality of components does matter. With use, some toilets tend to sag or bow, and this can affect the precision of parts such as the storage tank for waste. Moreover, it can also become difficult to open it, and this makes it susceptible to spilling.

When investing in these units, it is a smart idea to search for toilets that can be easily cleaned by a household cleaner. Also, try to buy models that do not require special equipment for cleaning.

This process usually takes around six weeks to be finished. Once that's done, the waste is buried, and the pin becomes empty and replaced. This process then repeats itself.

Continuous System

The other type of composting toilet is the one which comes with a continuous system and has a single chamber. This chamber is where all the waste goes, and the waste remains in this place until the entire composting process is completed.
