Our Story

In 2003, the out-break of SARS in Hong Kong killing hundreds of people reminded us how important the sanitation issue was. This was how the team of DEHTLET started to investigate an ecological alternative and user-friendly way to treat human waste without the use of chemicals and water.

The conventional on-site wastewater disposal systems applying the “drop and store” principle. The pit latrines or the portable chemical toilets create awful smell, insect breading and contamination risks. To minimise the drawbacks of the existing system, DEHTLET emphasis on the benefits of reliability and sustainability with simple mechanism.
