OTJI 3.0 READY FOR SERIAL PRODUCTION

Our urine-diverting-dry-toilet bowl Otji 3.0 is now mature for serial production. The design of Otji 3.0 contains the knowledge of over 15 years field-experience all around urine-diverting-dry-toilets (UDDT). The last couple of months we have spent to sharpen precision, functionality and appearance of our new design. Now the prototype of Otji 3.0 is ready for the factory.

Urine-diversion could become a cornerstone of climate-smart, resource-efficient dry sanitation systems. By separating urine at source urine-diversion enables the capture of several nutrients and is therefore increasingly recognized as a promising component towards sustainable agriculture.

But experience has shown that not all UDDT-pedestals did find sufficient support among the community where they were installed. The Otji 3.0 will soon offer a user-friendly, attractive design that could overcome acceptance obstacles and therefore unlock huge opportunities of nutrient recycling.

PARTICIPATORY ECOLOGICAL SANITATION AT "ECOESCUELA KOYAM": A COMMUNITY-LED RESPONSE TO CHILE'S WATER CRISIS

The Araucanía region of Chile, the ancestral homeland of the Mapuche people, is a land of extraordinary natural beauty and cultural richness. It is also a region under severe ecological stress. Despite abundant rainfall, rivers and lakes are chronically contaminated due to the absence of proper wastewater treatment. This water crisis threatens health, biodiversity, and local economies alike.

OTJI TOILET LAUNCHES "OTJI 3.0"

Dry sanitation is technically, economically and ecologically the preferable sanitation solution, not only for over 25% world population which is not having access to water-based sanitation. But dry sanitation needs more attention and constant innovation to finally overcome its commonly negative image as low-standard option and to unlock its huge benefits. A properly designed dry toilet is in fact superior towards water-toilet as it saves valuable water and at the same time prevents ground water contamination. Its off-grid installation is far less costly, while also maintenance is inexpensive.

ADVANCING LOW-CARBON CEMENT: LC3 FEASIBILITY STUDIES IN URUGUAY AND SENEGAL

As part of a project submitted to the Klik Foundation and supported by GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit), the consulting team from Grupo Sofonías and the EcoSur Network is carrying out a comprehensive feasibility study for the implementation of LC3 (Limestone Calcined Clay Cement) in Uruguay.
