The world of composting toilets has been marred by controversy in recent years. Eco-minded individuals believe that human waste should be treated just like any other organic waste. Is it a reliable way of toileting? Let’s delve a little further.
Composting toilets, also known as dry toilets, are biological sewerage systems that turn solid human waste into an inert oxygen-endowed environment where bacteria break down the water in it. The process is called aerobic decomposition.
1. Remote/Central – The bathroom here directs all the liquid and solid waste into a centralized or remote composite that is located in a non-edible garden. It can fundamentally be outside if weather conditions are favorable, in a dungeon, or the basement.
2. Self-contained – Composting toilets in this form typically house the composting system within their set-up. The compost system is positioned under the bowl where all human etcetera gets deposited.
Environmentalists continue to laud the use of composting toilets as a great alternative to flushing toilets. They are particularly applicable in areas where water is inadequate and cannot support mains supply to toilets. Estimates show that the use of composting toilets can save up to 280 gallons of water in a single day, translating to over 24, 984 liters per person in a year.
The main benefits of composting toilets include:
- They are more eco-friendly
- They circumvent costs associated with water and maintenance of flushing toilets
- They foster the growth of non-edible crops in areas where the amendment of soil is allowed
- They are ideally suited for remote areas

How to Shop for The Perfect Composting Toilet
You can buy a complete composting toilet, of course, and that will require you to go shopping for the one that has the best individual features. Since you are dealing with human waste that will be deposited somewhere in the open environment, you need to be cautious. Here are the must-have features in a composting toilet.
- An exhaust system, which removes unpleasant smell, gases, and heat from the decomposition process.
- A method to manage excess leachate and liquid
- A way to withdraw the compost mixture
- A ventilation system to foster the growth of aerobic microorganisms through aeration
- The compost unit, where solid human waste and other additives mix for composting
A conventional composting toilet is made of a compost bin, a toilet seat, a ventilation fan, a method to turn the compost sewage, and a door to pave the way for finished compost.
You can opt for a different system to deposit urine. It is crucial because urine has an overpowering scent, and it is the reason why potty-toilets smell filthy. Additionally, the critical right to erect a composting toilet is to do away with excess moisture, and separating urine is the first step to achieve that. If you don’t eliminate urine, the composting process will inevitably take longer.
Another critical aspect of the composting toilet set-up is the heater. The heater is highly applicable in areas where temperatures tend to drop drastically. It would help if you had it to facilitate the composting process. If the waste becomes too cold, it will cease to compost rendering the chamber a typical storage segment.
If you don’t want to settle for the artificial composting system, you can purchase a fully-equipped system that entails the following individual components:
- Agitator bar
- Spider handle
- Mounting screw
- Compost chamber
- Liquid drain
- Liquid bottle with a grip
Choosing the best composting toilet can be tricky. However, it would help if you explored different composting toilet types in the market so that you pick one that suits your needs. Here are some:
