Global Sanitation

Global Sanitation

Loowatt began to serve toilet customers in Madagascar in late 2012, with a pilot public toilet and treatment system producing energy and fertilizer. We are currently rolling out our waste-to-value urban sanitation pilot system with 100 household toilets in Antananarivo.

This work, funded by grants from the Bill & Melinda Gates Foundation’s Grand Challenges Explorations initiative, completes every step of the sanitation value chain: clean toilet provision, top-quality service, biogas, electricity, and fertiliser production.
