Whether homemade, or dynamically designed, a toilet that is designed for camping provides an alternative to human waste pollution. There are a variety of models to choose from, from light-weight foldable devices, to fully-flushable systems. The Easy Care Toilet is one of the most efficient toilets, and is used by both the US Military and the National Park Service. It is lightweight and easy to unfold and then re-pack, ideal for hiking to multiple campsites. The BioToi camping toilet was designed for the Norweigian army. It is inexpensive and simple, although not quite as easy to carry as the Easy Care model. Visa Potty is a portable, flushable model. A little more expensive, but well-designed for use and cleaning.
What then, makes these toilets eco-friendly? What about outdoor facilities which use chemicals to break-down waste, or bags that will only pollute the environment? To practice sustainable camping, it is important to not only use a camping toilet, but to use one that will not have a negative impact on the environment.
If purchasing a product, look for models which use biodegradable bags, such as patented Wag Bags. Wag Bags are made from polymers and natural starches, and are made to break down within six to eight months. During long camping trips, or in situations where it may not be possible to store waste to be disposed of off-site, these bags can be buried in the ground. If burying excrement, dig a hole six inches deep, at least two hundred feet from any water or other campsites. Do not bury toilet paper.
Toilets which use chemicals are not safe for the environment. Toxic chemicals, to mask odors and break down organic material, are dangerous for animals, children, and the earth. Try to avoid introducing any unnatural substances into a delicate ecosystem.
