Loowatt

Loowatt is a waterless toilet company, using a container-based sanitation model in which the containers holding waste are periodically removed for treatment. Waste from the toilet can be sent to an anaerobic digester to create biogas and fertilizer.^{[1][2][3][4][5]}

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".^[6][7][8]
