Sustainability Journal – Dry toilet

Compost toilets are a low cost, chemical free method for dealing with solid waste.
The dry toilet eliminates waste, avoids to use the flush,  recycles otherwise noxious waste to sweet smelling humus. A normal home toilet can use up to 6-liters of the water with every flush. If you start calculating the number of flushes, you might be shocked to see how much water you are actually wasting to get rid of your own waste.

Our dry toilet is in our garden in a small shelter. There is a hole which is use like toilet (so you are not sitting during your process – actually is better for your digestive system). After use the toilet we should add sawdust. When the hole is full, we take off the matter and put it on the place which we choosed. (Be careful what you have near in this place, because this matter is very rich with nitrogen material and because of that we killed one tree already). There this material is resting and we will can to use this kind of compost for our trees in the right time (around one year after).

How it works?

The dry toilet doesn’t use water. Just after use, you should add handful of carbon organic matter which is dropped into the toilet. This organic matter should be small for more efficiency. For example, it could be: sawdust, wood ash, peanut shells, rice husks, half-finished compost, crushed leaves, etc. The matter in compost toilet should rest one a year before use. The type of compost produced is suitable for fruit trees, trees and bushes, it is not recommended that it is used directly on the vegetable patch.

Sometime is recommended not pee in the dry toilet (could be bad stink because after the matter in the toilet is to much wet and the process of composting is not ideal) but if you are adding enough carbon materials and putting the matter from the toilet into a bin outside for composting process regularly so should be ok.

One of another question is how we can substitute a toilet paper (because it is not question about a recycle but we should not forget how is a process of making of the toilet paper) … Some ideas is to use natural leaves, but we are still thinkig about it…
