7 Reasons to Consider a Composting Toilet

Why should you consider a composting toilet? In order to answer this question, it is important to first understand how composting toilets work. True composting toilets optimize the natural microbial decomposition process to fully convert waste into fertilizing soil. In fact, most waste treatment systems, including municipal wastewater plants and septic systems, also rely on bacteria to digest waste. Composting toilets, however, are able to process the waste much more efficiently by eliminating detergents, flushing water, and by introducing carbon and oxygen. The most advanced composting toilets support aerobic microbes (microorganisms that need oxygen to survive). Aerobic microbes dramatically speed up decomposition and are odorless. Typically, the liquid waste is evaporated. The result is an environmentally friendly toilet that can be quickly and easily installed anywhere at a fraction of the cost of conventional systems.

So once again, why should you consider a composting toilet? There are several really good reasons to consider using a composting toilet.

7 Reasons to Consider a Using Composting Toilet

1) Unlike traditional flush toilets, no water or sewer connection is required. Therefore, if a water and sewer connection is not available or not practical, then a composting toilet would be a great choice. Even if a water and sewer system is available the connection may be expensive and very disruptive.

2) To protect public health and safety. Since many composting toilets have no discharge, there is no possibility for them to contaminate lake or groundwater with pathogens and viruses. The same cannot be said of septic systems. Therefore, anyone with a lakefront property or with a well should seriously consider a composting toilet. After all it is the same water you drink or swim in!

3) To protect the environment. Using a composting toilet will reduce your household water consumption by approximately 25 percent and keep unwanted nutrients such as nitrogen out of our water.

4) Ease of installation. Most composting toilets can be easily installed within an hour or two. Also, unlike septic systems, many composting toilets do not have set back restrictions from lakes, streams, wells, etc.

5) Composting toilets are not prone to catastrophic failures such as flooding or sewage backflows. This makes them a good option for use in areas susceptible to flooding

6) Portability. Since many composting toilets do not require a water or sewer connection they can be moved fairly easily. This makes them a great choice for tiny homes, boats, and RVs.

7) Disaster relief. When conventional treatment infrastructure is devastated by natural disasters, composting toilets can provide a rapid and cost-effective means of restoring proper sanitation.


What Features do the Best Composting Toilets Have?

The best systems fully process waste and produce safe compost. The best way to determine if the system produces a safe end product is to make sure that it is tested and certified to American National Standards Institute/NSF International (ANSI/NSF) standard 41. NSF International is a public health and safety organization and most regulators require systems to be certified to this performance standard.

What to do with the Finished Compost?

Composting toilets that fully process waste will reduce the volume by over 90 percent. Therefore, removal of finished compost is done very infrequently. The compost is often used as a fertilizer for ornamental gardens, trees, or shrubs.

Does a Compost Toilet Smell?

No! Composting toilets are vented to exhaust odors from the bathroom. Advanced systems go even further by allowing aerobic microbes to thrive, which eliminates the odor-causing bacteria.


Do Composting Toilets use Water?

Most composting toilets do not use water; however, some central systems use ultra-low flush toilets, which do use a very small amount of water to transport waste to the composting tank. This is a fraction of the water consumed by traditional flush toilets.

Do Composting Toilets use Electricity?

Composting toilets are available in both electric and non-electric models. The electric models have improved air flow and evaporation, however, both versions use microorganisms to decompose the solid waste.


Although composting toilets are unlikely to replace conventional waste treatment infrastructure, they do allow toilet facilities to be easily and economically added literally anywhere. For that reason, you can be certain they will continue to increase in popularity.

Happy Composting!
