If you are considering a composting toilet for your home, it can be overwhelming to know where to start!

How do you use one? Can you pee in a composting toilet? How often should you empty the composting chamber? How do I dispose of the waste?

This blog post will answer all those questions and more. Read on for tips that will have you using a composting toilet like a pro in no time!

How do composting toilets work?

A composting toilet is a type of dry toilet that treats feces through a biological process known as composting. There are 2 types of composting toilet system; self-contained, also known as split system composting toilet, and central composting toilet (internal link)

This process decomposes organic elements, transforming human waste into compost. Microorganisms undertake composting under controlled aerobic circumstances (primarily bacteria and fungus).

Because the majority of these toilets do not use water to clean or flush, they are referred to as "dry toilets" or "waterless toilets."

After each use, a carbon addition such as sawdust or peat moss is supplied to assist in the decomposition of the solid waste in various types of composting toilets. This method creates air gaps for the aerobic decomposition of human excrement.

This also raises the amounts of carbon and nitrogen, which reduces possible smells.

A composting toilet is ideal for holiday homes, your own house, RV's, cabins and pretty much any other residence you can think of!

How to use composting toilets?

Using composting toilets for day to day use is a lot more simple than many people would think.

Let's begin by looking through:

Step by step guide on how to use composting toilets

Step 1:

Begin by putting compost material such as peat moss or coconut coir- these materials tend to help with reducing bacteria that typically makes the toilet smell.

Step 2:

Sit on the toilet seat if you need to urinate. Don't be concerned about where the liquid is going as it will enter the liquid chamber via the openings.

This is done to prevent the toilet from smelling when the liquid and solid feces combine. Adding a little moisture by adding water can dilute the liquid waste, but you will have to empty it more frequently.

Step 3:

If you're using the toilet for a 'number 2' - or in other words, solid human waste- engage the trap door (bear in mind, there may be different technicalities depending on which composting toilet product you buy) as soon as you sit.

The toilet paper goes in the waste container with the other solid wastes- Make sure you use toilet paper that will degrade and decompose really fast.

Step 4:

Some of the composite toilet designs have a waste-stirring mechanism. Stirring permits the mixing of solid wastes with dry turf. The ventilator delivers air to dry and prevent the solid waste from stinking.

Step 5:

Every 3 to 4 days empty the liquid waste to avoid odor. After around 90 uses, dump the solid trash. You may discharge the solid waste into an organic bag since it will easily decompose.

You may even vacuum it into your compost heap and utilize it on your garden later on.

How do you dispose of urine from a composting toilet?

Peeing in compost piles is possible!

Through the microbiological process of decomposition, urine and other organic waste in a compost pile will decompose into fertilizing material. The bacteria in a compost pile that generate heat are big enough to avoid being destroyed by ammonia or urea.

Composting toilets make it simple to separate and utilize solid waste for fertilization on the one hand, and to separate and use liquid manure as mulch in a water-rich landscape on the other.

When you don't filter out germs before exposing them to an open environment, adding liquid manure from septic tanks might cause environmental concerns.

Find out how to dispose of solid and liquid waste from composting toilets in detail.

Can you use regular toilet paper in a composting toilet?

Regular toilet paper can be used with a compost toilet- toilet paper can be put directly into the solids bin, or solids waste chamber of the composting toilet.

It will break down in there along with other human excreta. But it is best to avoid using too much as depending on the material of the toilet paper, it can affect the decomposition process.

How much toilet paper can be put into the compost chamber?

Although there is no limit to how much toilet paper you can use, it's best to consider the capacity of the toilet bowl as you don't want it to overflow.

It's also important to consider the environmental impacts of some types of toilet paper - I would suggest using one that is advertised towards RV or boats.

These are typically more eco-friendly and is one way of you continuing to help the environment without depriving yourself off a basic necessity. They are eco-friendly as they tend to avoid using harmful chemicals in the dying and bleaching process of its manufacture.

One suggestion is experimenting with your tissue in smaller quantities to ensure it decomposes easily so as not to affect the decomposition process.

How often do you have to clean a composting toilet?

As we mentioned compost toilets need to be emptied every 3-4 days, although this can vary depending on what compost toilets product you decide to install and purchase.

However it is also vital to ensure that a thorough clean is carried out for composting toilets every few months, ideally every 2-3 months.

This is so that you are maintaining good sanitation and hygiene, and ensuring the composting bin is thoroughly cleaned out, preventing bacteria build-up and bad odor.

When you clean your composting toilet, be sure not to let any chemicals enter the chamber, as this can mess with the composting process.

Do Composting toilets stink?

When managed correctly, composting toilets should not stink.

Toilets compost using high-carbon content, the odors of human waste are neutralized. They produce a perfect environment in which breakdown processes may commence with germs, good bacteria and other microorganisms.

The end result of a composting toilet is soil, which smells like a forest floor. A rich and fertile soil.

Usually, a few scoops of sawdust, coconut coir or other high-carbon dry material are inserted into the toilet after use.

The high-carbon organic substance neutralizes the scent right away and stimulates microorganisms to start the natural decomposition and composting process.

How do you know when to empty a composting toilet?

Knowing when to empty a composting toilet is very simple and largely depends on the capacity and volume of the composting toilet, and also how many people use the toilet.

When the pile in the composting chamber is full, you will know that the contents require disposal.

As a typical guide, empty contents from the liquids and solids tank every 3-4 days. Your composting toilet may have a guide for the liquid container, to show when it is getting full.

Where do you dump your waste from a composting toilet?

Emptying a composting toilet can be a harmful process if carried out incorrectly.

A disposal station in a toilet urine bottle is the perfect place for the safe disposal of the pee collected. These dumping stations process waste liquid in a waste treatment facility and have sewage sludge rules.

There are also disposal stations for solid excreta, and some disposal points have stations for both solids and liquids.
It is important to wear a mask and gloves to protect yourself from inhaling bacteria that could potentially be harmful to you.

Do not empty the toilet in the vicinity of waterways or water supply. Make sure your dumping site with the nearest water body is at least two hundred feet away.


Human consumption and freshwater pollution reached a stage where scarcity of water in the coming decades may limit agricultural productivity, ecosystem functionality and the urban supply of drinking water.

There are many different companies that produce and manufacture composting toilets to choose from- this includes Airhead, Nature's Head composting toilets, Sun mar and Separett villa composting toilets.
