Energy-producing waterless toilet system

2011 - 2015 • Loowatt Ltd
project database

Purpose

Developing and testing a waterless toilet that seals and stores waste in biodegradable film, within a portable container, for easy transport to a local anaerobic digester in Antananarivo, Madagascar.

Activities

Loowatt received GCE Phase 1 funding in 2011 to implement the Antananarivo Pilot. The system began to serve paying customers in late 2012.

In this project, Loowatt Ltd. further developed and tested a waterless toilet that seals and stores waste in biodegradable film, within a portable container, for easy transport to a local anaerobic digester. The toilet was functionally resolved in 2011 and had been tested extensively, first in the company’s UK office, and then in a London community. Loowatt implemented a pilot system including a toilet, anaerobic digester, and fertilizer production facility in Antananarivo, Madagascar, which has now been serving paying toilet and energy customers, and producing compost, since November 2012. All system components were designed and fully specified by Loowatt Ltd. Additional local support was provided by Water and Sanitation for the Urban Poor. Loowatt’s unique technology has applications in many parts of the world and the company is looking to expand its operations in 2013.
