4 Facts About Portable Composting Toilets

A portable composting toilet is a green alternative to a traditional portable toilet. Rather than requiring the use of disposable bags the composting toilet uses composting principles to provide a virtually odor free alternative.

Reduces Water Use

Since it is a self contained unit, the portable composting toilet uses no outside water source. Traditional toilets can use as much as five gallons of fresh water per flush. Eliminating that water for waste processing means conservation of resources for drinking. The closed system works through aerobic decomposition of the solid waste and evaporation of the liquid waste resulting in solid garden mulch.

Produces Fertilizer

The byproduct of the portable composting toilet is a mulch made from human waste. Other items that would normally go into a traditional compost pile can also be added to the composting toilet, such as coffee grounds, egg shells and vegetable waste. They type of toilet you would need depends on local laws regarding liquid fertilizer. The composting toilet will typically either produce two types of fertilizer, or will evaporate the liquid and leave behind just the solid waste. This waste is high in nutrients that plants need to grow.

They don't Smell

Composting toilets are not the same as old style outhouses.  Since they are not an open system, they don't vent the byproducts of the breakdown of material to the atmosphere. A properly configured composting toilet produces no noticeable odor. Because of the air flow in the design, these toilets typically produce less odor than a traditional toilet. The only time that a composting toilet will produce an odor is if the unit is not emptied before it gets over full and the air flow is disturbed. Also available are natural additives and enzymes that can be mixed into the composting unit to aid in the breakdown of the waste and elimination of odor.  These additives stimulate the growth and activity of the anaerobic bacteria in the compost.

They're Good for the Environment

Composting toilets are good for the environment since they reduce the amount of fresh water used for processing waste. They also reduce the need for septic systems that are built under ground and can pollute the ground water supply. They eliminate the need for complex waste treatment plants and reduce the possibility of cross contamination. This is particularly important at natural locations such as beaches, national parks and public gatherings.

Portable composting toilets are a green method for disposing of human waste. These toilets are a convenient addition to your RV, poolside, or camping equipment. They provide the benefit of reduced water use in conjunction with the creation of usable fertilizer for your garden.  When selecting a portable composting toilet, you should make certain that it can accommodate the number of people that are expected to be using it.  Size it to small and you may overfill the unit and get unpleasant odors.
