To bring performing and affordable malodor counteracting solutions to the beneficiaries of the Foundation’s WSH initiatives by making the use of affected toilets a more desirable experience.
- The fecal reconstitution (4 molecules) produced similar results as the latrine reconstitution (same 4 molecules + 4 others found in latrines sludge) in every country.
- A reconstitution with butyric acid, p-cresol, indole and dimethyl trisulfide can evoke an olfactory experience similar to the one during the use of latrines in three different continents.
- This confirms and consolidates previous studies on fecal odors that butyric acid, p-cresol, indole and dimethyl trisulfide are strong contributors to the human fecal odor.
- Stable synthetic reconstitution of pit-latrine malodor is essential for perfume creation, the development of odor control method and for a better understanding of the perception of the latrine malodor.
The purpose of this project is to bring performing and affordable malodor counteracting solutions to the beneficiaries of the Foundation’s WSH initiatives by making the use of affected toilets a more desirable experience.
