Frequently Asked Questions

Composting toilets are definitely not a cheap investment. Many of them have price tags that are well over $1000! Before you make a decision on the best composting toilet for your situation, take a look at these frequently asked questions. This should give you more insight into the features to look for in a composting toilet.

How Do Composting Toilets Work?

A composting toilet is designed as a waterless waste system that requires no sewage or water connection. They are designed to use the natural processes of decomposition and evaporation to recycle human waste.

Solid waste is more than 90% water which can be evaporated and carried back to the atmosphere through a ventilation system. The small amount of solid material can then be converted into fertilizing soil by natural decomposition.

Composting toilets have to maintain the correct balance between oxygen, moisture, heat and organic material to ensure a rich environment for aerobic bacteria to transform the waste into compost.

Is Urine Good For Compost?

Human urine is rich in nitrogen, potassium and phosphate which are all essential for healthy plants. It has smaller amounts of trace elements plants need to thrive. Urine can also speed up the chemical process in a compost heap, making it a better fertilizer for growing plants in your garden.

What Is A Compost Toilet System?

A composting toilet is a type of waterless toilet that treats human waste by allowing it to decompose organically. True composting toilets do not require the waste to be treated with chemicals to speed up the decomposition.

Can You Put Tampons In A Composting Toilet?

Tampons can be placed in a composting toilet, however, you may find that not all the materials in the tampon product will decompose as quickly as expected. Depending on the product, the material may not fully decompose at all. This means you may need to separate the non-decomposed materials from your compost heap.

Do Composting Toilets Need Electricity?

Not all composting toilets require electricity. Usually, power is only required for a circulation or ventilation fan. Some composting toilets have a small heater to help evaporate liquid waste more fully. Some toilets use batteries instead of AC outlet power.

How Often Does A Composting Toilet Need To Be Emptied?

The size of the composting tank will determine how often the toilet needs to be emptied. Most composting toilets can be used for a couple of weeks with 2-4 people using it regularly. Level indicators can help determine when the toilet is reaching a height that requires emptying.

Do You Need A Permit For A Composting Toilet?

Some cities and municipalities require permits for a composting toilet in order to ensure the waste is being handled appropriately. Before you install a composting toilet, be sure you are checking with your local housing authority to determine if they require a permit to be filed.

How Much Does A Composting Toilet Cost?

Commercial composting toilets can cost up to $10,000! Luckily, residential composting toilets are much cheaper. A self-contained composting toilet can cost anywhere from $500 up to $2000 or more. More cost doesn’t always mean better quality, however. Be sure you understand what features you are getting for the cost!

What Are The Benefits Of A Composting Toilet?

There are many benefits to using a composting toilet. These types of toilets are ideal for RVs, boats or even small cabins or lake houses. One of the biggest benefits of a composting toilet is that it can be installed in any location where there is not a water source or waste system close by.
