The lack of clean water and effluent disposal in many developing countries has moved into the focus of public attention in recent years. This is why the United Nations has declared the decade from 2005 to 2015 to be the "International Decade for Action Water for Life".
Since 2012 TiSUN solar system has supported the ground-breaking project of the "LooWatt" toilet, which guarantees an energy efficient use of toilet water with the power of the sun and without any energy waste. It is an application that offers potential not only in developing countries, which is also confirmed by the “Climate week award for the best new product”. The “LooWatt” toilet system was honoured with this prize on March 4, 2013.
One billion people worldwide have no toilet facilities, every ninth person has no access to clean drinking water. Yet in the countries of the first world about four litres of fresh drinking water are used for a single toilet flush. The patented "LooWatt" toilet operates without water and has no unpleasant smell. The small parcels of “deposits” containing human waste are collected from a container and added to an anaerobic digestor, which produces methane gas. The gas is collected and can be used for light generation or cooking.
The digestion process occurs at temperatures between 30 and 35 °C, and in colder climates heat needs to be added to the digestor to achieve the best digestion. The TiSUN solar system adds the heat needed to achieve the required operating temperature of the system of 30 to 35 degrees.
Thanks to the solar system the “LooWatt” toilet is able to generate human biogas, which can be recycled. “The toilets are very successful and we are already in talks with several potential customers”, explains the inventor of the system, Virginia Gardiner. “With TiSUN we found a partner,that is interested in environmentally friendly usage of energy systems.”
