Loowatt creates physical, emotional and environmental wellbeing through waterless sanitation. Wherever there is a need for non-sewered toilets, people deserve a clean, safe, and desirable experience. Chemical toilets, bucket toilets, and pit latrines are make do answers that just won’t do. Loowatt provides waterless flush toilets for homes and pop-up locations everywhere. Our future-proof, patented technology provides a high quality waterless flush that locks in odour and disease without using scarce and high-value water. Servicing our toilets is safe, simple and quick. We support a closed-loop system, where waste is hygienically contained for easy transport to treatment infrastructure. This stops disease spreading and supports resource recovery. Wherever we install toilets, we work with local partners including servicing companies and utilities to ensure closed-loop and value-generating sanitation solutions that meet the requirements of the Sustainable Development Goals (SDG 6.2).

Other products

Loowatt toilets use a patented sealing mechanism to wrap human waste in biodegradable polymer film. The film, which lines the toilet bowl, is pulled through the sealing unit when the toilet is “flushed,” enclosing the waste in a removable cartridge. The cartridge is then emptied into an anaerobic digester, where the waste and polymer film are converted into natural gas and fertiliser. Providing sanitation also requires the safe collection, transport and treatment of faecal sludge. Loowatt develops toilets, pre-treatment technology, and a mobile app that support an efficient service that meets the standards of governments and utilities and can be scaled to address the sanitation challenges of growing urban centres.
