How Do Composting Toilets Work?

Composting toilets are a natural way to process and decompose human waste. If we take a look at human waste it is 90% water which is very easily evaporate and released to the atmosphere. The solid component left can be re-used for fertilizing soil.

If you imagine a home compost for food scraps then this is almost the same concept as a composting toilet. With the optimal balance in the composting chamber the perfect environment can be created for bacteria to convert waste into fertilized soil that can be re-used.

With a composting toilet the processing chamber can be designed to effectively break down human waste. When properly done the fertilized soil will contain no pathogens or viruses as the bacteria has effectively broken these down.

In a nut shell there are 3 key elements that a composting toilet must successfully achieve:

  • Break down the waste and toilet paper with no odor
  • Promote sufficient bacteria to break down the solid waste
  • Evaporate the liquid component of the waste.

Now that we have an understanding of how they work let’s take a detailed look at the best composting toilets!
