The Working Mechanism

Composting toilets have been made to aid in recycling. They recycle human excrements via a natural evaporation and decomposition process. On average, human waste is made of 90% water. This returns to the atmosphere through the vent system of the toilet. In some modern systems, there is a heating component which pushes the evaporation along further, speeding things up. However, the compost should never be fully dry as the decomposition needs moisture to continue. The remaining solid waste is then converted into manure through natural decomposition which is useful for the soil. This is done with the aid of bulking material. This consists of popcorn, peat moss, sawdust and some other materials. This is sometimes mixed with waste using a crank handle. The material mixes with the waste and allows for a proper aeration of the pile. This makes sure that the oxygen to flow through the compost and speed up the process and make sure that the compost is safe to handle. This alsi makes sure that the compost is free of any odour.

Types of Composting Toilets

There are two main types of composting toilets. Both have a different set of perks and advantages to them.

  1. Self-contained Composting Toilets: This type of toilet needs a direct installation in the bathroom. They have two common types: ones that run on electricity and ones that do not require electricity to work. The electric units use the power source to fuel a heating component which is controlled by a thermostat. It also powers a fan. Moreover, the electric model has the perk of being able to hold a lot more waste in the Bio-drum as they tend to have more capacity. The additional warmth enhances air circulation which encourages bacterial activity for composting. There are several advantages of self-contained composting toilets:Top 10 Best Composting Toilets in 2019
  • They are economical
  • There is no need for plumbing
  • They work great during the winter season
  • They are extremely easy to clean
  • They have a sleek high-gloss finish

There are some disadvantages of a self-contained composting toilets:

  • These are only the best for people with a constant electric supply
  • There may be some electrical issues
  1. Central Composting Toilet Systems: These exclusive toilets work with a two-piece system. It makes use of features from both, traditional toilets and eco-friendly central composting systems. This particular type of toilet has two main types:
  • Waterless: It does not need any water to function. The air flow of the unit is connected via a pipe to another component called the Centrex A/F which is located under the toilet. It ensures that entire process of composting is free of odour and stink. The A/F unit has been tailored to create a slight vacuum to push down air in the bathroom. This type is thus the perfect fit for places where water supply is limited.
  • Pint Flush: This version is more popular amongst the two options. This can be due to the water seal and the flushing liquid features. These lend it a resemblance to a traditional toilet.

Pros of Composting Toilets:

Top 10 Best Composting Toilets in 2019

There are many pros of owning a composting toilet.

  • The toilet will not clog: Since there is nothing to flush down the drain, nothing will get stuck in the pipes. There is no need to even own a plunger of any kind. A typical toilet appears to be large enough for all the waste to get in and go through, but it narrows down to fit into the pipes which leads some kind of clog and leaves behind some kinds of stains and messes on the toilet. Since this is not how composting toilets work, there is no chance of a clog.
  • There won’t be any noises/splashes: Composting toilets are dry in nature which means that there is no sound created when nature calls. Since there is no water involved, there are no splashes and there are no flushing noises created which can be embarrassing. These toilets also make sure that the urine is separated from the solid waste.
  • Composting toilets do not stink: A general assumption about composting toilets is that they make the house smell and stink up. But this is not the case. As a general rule, there is very little odour created. Any minimal odour created is similar to that of the smell of wood.
  • Compost toilets conserve water: A traditional toilet uses up about 1.6 gallons of water due to low-flush technology. Older technologies can utilise up to 7 gallons of water. This means that multiple people households waste millions of gallons of water per day. The water and waste is then purified at a waste processing plant, where purifiers and chemicals are to clean water and the process starts all over again. Using a composting toilet in a single household can save over 30k gallons of cleaning water every year.
  • The clean-up is easier: Since there is no splashing, no clogs and the mechanism is made differently, the bathroom tends to be cleaner and more sanitary.
