Using a patented and simple sealing technology to contain human waste within biodegradable film, with a unique odor-inhibiting system, the waste is then stored in a cartridge for periodic emptying, which can be weekly or daily, depending upon level of usage and capacity requirements.
The waste can then be treated through anaerobic digestion to produce biogas and fertiliser.
Loowatt began to serve toilet customers in Madagascar in late 2012, with a pilot public toilet and treatment system producing energy and fertiliser. It is 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.
