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.

Composting Toilets Work in Two Fundamental Ways

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:

Nature’s head self-contained composting toilet – It is one of the top-rated in the market and comes with an intuitive design. It has a firm spider handle, a peat moss starter to help in the decomposition, and a solid waste unit that can withstand over 90 uses before emptying. It also boasts of a space-saving design that makes it a great fit in tight spaces.

Nature’s head dry composting toilet – If you are looking for a model that efficiently diverts urine, this one is right on the money. It is also compact and lightweight, with a standard handle that is viable whether you are in a boat, at home, RV, or a remote cabin. The fact that it is stainless makes it such a convenient option for an outdoor toilet setting- it can withstand extreme weather conditions.

Villa 9215 DC/AC – It is the perfect choice when you want to go fully waterless. It is also a pretty versatile model because it can use both solar and electric energy to operate. What’s more, it comes with up to 10 compostable bags that will make sure you don’t have to empty the bin now and then.

Composting Toilets Q&A

What are Composting Toilets?

They are the category of toilets that use little or water to flush solid human waste. Instead, the waste is mixed with other additives such as sawdust to turn it into a useful fertilizing compound.

How do Composting Toilets Work?

Composting toilets work by depending on bacteria to break down waste through a process known as aerobic decomposition. The resultant mixture can be hauled away, but only with licensed permission from the relevant authority.

Do Composting Toilets Smell?

No. A composting toilet will not, at any time, stink up your house. A bathroom that has a composting toilet will smell better! It is because the urine that causes the characteristic odor is usually done away within the early phases of composting.

Where to Use Composting Toilets?

You can utilize composting toilets in a boat, at home, when camping, when in remote areas, or an RV.

When to Empty Compost?

For a couple, it may take 3-4 weeks for the composting bin to fill up. A family of 4 or 6 would take half the time to fill it. It would be best if you emptied the compost bin whenever the need to arises. Please don’t wait for too long to leave the waste; it may lead to a burst or clogging.
