Loowatt is a waterless toilet company. Waste from the toilet can be sent to an anaerobic digester to create biogas.
In 2012, the company started a trial project in Antananarivo, Madagascar.
In July 2013, the company received a grant of US$1,269,936 from the Bill & Melinda Gates Foundation to design and build a "commodity-generating waterless toilet system".
