Dry Toilet

True transformation is about doing, in fact, what we believe! 

Sustainability lies in thinking about solutions to the paradigms and problems that we face today as a society. Chemical toilets and using holy water in an irresponsible way, is no longer the way of thinking that we want. We believe in new ways of relating with ourselves and with nature. Therefore, we seek coherence between what we do and what we promote, so that we can tune into the resonance of true sustainability. 

The correct use of dry toilets is very simple and guarantees the success of this technique:Just throw enough amount of sawdust, like a dry “dump.” 



Dry toilet is an ecological alternative in the treatment of human feces. Despite the aesthetic resemblance to the common toilet, stools are stored in a place that is not in contact with the external environment, where each defecation is poured a handful of sawdust to keep them dry, to avoid stench and to prepare the organic compound for fertilizer. 

Without water, the dry toilet prevents the discharge of waste in pipes connected to the treatment centers or directly in streams and rivers, not to pollute them, and also produces organic compound at the end of its process.

Do dry toilets smell bad?

No! When built, maintained and used properly, dry toilets do not smell bad.

Can I urinate in the dry toilet?

We propose that women do and men do not. Too much urine can soak the compound, which is not good for the process. Since it is easier for men to urinate in trees, which need urea, we propose this way!

Can I throw used toilet paper with feces?

Yes! The paper also helps in the formation of the compound. Just remember to cover it along with sawdust.

Can I throw absorbents, diapers and cigarette butts in the dry toilet?

No! Never throw any type of plastic or other material that is difficult to decompose. This disrupts the bacteria that are friendly to organic compost.

How is dry toilet cleaning done?

Cleaning of toilet seats is carried out with common bactericidal disinfectants. We just take care not to drop it into the compost, which must be kept dry, and which needs the compost-friendly bacteria to transform.

How does the dry toilet work?

The dry toilet turns the human feces into organic fertilizer compost for planting. It provides specific conditions for the right bacteria to develop and play their part in the transformation process.

The conditions should be:

– Hot: Composting is done between 40 and 70 degrees, by bacteria that like heat. That is why it is very important to build the bathroom in a place where there is a lot of sun.

– Wet: Like a sponge that has just been squeezed, it cannot be too dry or too soggy.

– Uniform: All parts must be mixed and of the same consistency. The compound cannot be compacted or uneven.

– No bad smell: Bacteria that generate bad smell do not help in composting. If the dry toilet shows bad smell, this is the signal for interventions such as throwing a little bit of lime, ash, more sawdust or whatever it takes to return to optimal composting conditions.
