What Is A Composting Toilet?

First thing off, we need to understand what is a composting toilet. Composting toilet is a waterless toilet system that decomposed human waste and convert it into a compost substance. During the process, it maintains the nutrients from human waste which can be use as fertilizer for plants and other applications.

Due to its processing procedure it is also called as “biological toilet”. Another term it uses is “dry toilet” because it uses minimal water or doesn’t use water all.

How Do Composting Toilet Works?

To easily understand how the it works, decomposing the human waste proceeds in three important process. The main goal here is to convert the human waste into compost fast and safely for usage.

Firstly, the waste needs to be evaporate. There is a huge part of human waste that consists of water which is about 90-percent. This needs to separate the solid from liquid and afterwards the liquid should be evaporated fast in the air. This is the reason why it requires a proper air ventilation to scatter it in the open air.

Next is, to convert the solid waste into compost or fertilizer. An ideal composting toilet system needs an additive substance like peat moss and any other type to minimize the odor and breaks it down efficiently to become organic.

And lastly, provides a harmless and easy to handle compost. Handling people’s waste is something that no one wants to do, right? That is why the end product should be properly treated to make it safe, odor free, full of nutrient and to be use for your garden plants.

The following composting toilet system that we are going to review today satisfactory meets all this requirement for your safety.

The advantage it provides is that, it doesn’t require frequent maintenance and gives you comfort with almost the same as your regular toilet. However, it is fixed on your home and you cannot bring it along.

Composting procedure takes a long time to process because it doesn’t have a solution and adequate temperature for speedy method.

The second type is the “Self Contained Composting Toilet” which is the most popular and that’s what we are going to feature in our best composting toilet review here.

The self-contained composting toilet consists of a toilet bowl and the composting element is directly attached into it. In short, they act as one unit. Therefore, you can carry and take it anywhere you may want to.

To speed up the composting process and removes the odor, it requires a power supply for the heating element and fan. Some of them can be powered by 110v AC from your home outlets, 12v DC from car battery or solar cell for your total convenience.

There you have it, I hope you have now a clear understanding about the composting toilet with their advantages and disadvantage. I should be featuring three of them but the third one which is the Sun-Mar Excel Self-Contained Composting Toilet has a very low rating. Most customers who bought it has encountered many problems on it the fact that is more expensive than the two.

Both the Nature’s Head and the Villa 9215 AC/DC are excellent toilet and earns high ratings from customers. The choice lies on your own preferences and applications.
