Does your survival plan include bugging out to an off grid location away from major cities? If it doesn’t already; it should. In the case of a SHTF type scenario you won’t be able to rely on power and water utilities. So how do you use the toilet?

Composting toilets do not require water and some of them do not require any electricity. Composting toilets make for a great option in any off grid living condition.

How Does a Composting Toilet Work?

Human waste products are roughly 90% water. In many composting toilets the liquid is separated from the solid waste and the liquid evaporated. The evaporated liquid is vented to the outside.

The solid waste is converted to high quality fertilizer and turned to compost by mixing with organic material such as peat moss. When properly composted the remaining waste will not hold any pathogens or viruses and is safe for plant fertilization.

The best composting toilets will properly mix organic materials with the waste and separate the liquids from the solids resulting in an odor free process. This complete composting of solid waste is important to reducing odors and developing a nutrient rich fertilizer for your garden.

 

Top Factors to Consider Before Purchasing a Composting Toilet

When making a decision on what model of composting toilet is right for you it is important to take several factors into consideration. Some of the main features of the best composting toilets are as follows:

Features

Capacity – Do you want to empty the compost bin daily? If not, you may want to look at composting toilets that have a higher capacity.

Size – You will want to take careful consideration of the size of the space you plan to install your composting toilet. The height of toilet can also be of concern. Some models have a higher seating position than others which may be of concern for taller people or shorter people.

Price – Like with any major item you are looking to purchase, price is an important factor to consider. Composting toilets can be a bit pricey, but they are worth every penny in water and fertilizer savings. You also get what you pay for.

Can You Use Toilet Paper in a Composting Toilet?

Absolutely! The toilet paper actually aids in the decomposition process by adding additional organic matter to the waste. Most models of composting toilets suggest using single-ply toilet paper to improve breakdown time, but you don’t need to use any special toilet paper in these units.

Do Composting Toilets Smell Bad?

Believe it or not, no they don’t. If the composting toilet vent system is properly installed and the toilet has sufficient organic matter to aid in complete composting you will not smell it at all. Additionally, some models do a great job of separating liquid and solid wastes which also prevents your house from smelling like an outhouse.

Runner UpSeparett Villa 9210 AC/DC Composting Toilet


The Separett Villa 9210 is a urine diverting composting toilet with a waterless design. The unit is a bit on the pricey side, but is well worth the money due to its ease of use and quality construction.
