Toilet turns human waste into biofuel, fertiliser
An aeroplane-style vacuum toilet can help turn human waste into electricity and fertilisers.
London: An aeroplane-style vacuum toilet can help turn human waste into electricity and fertilisers.
The No-Mix Vacuum Toilet, which uses vacuum suction technology like aeroplane toilets, splits human waste into solids and liquids, Daily mail reported Thursday.
Liquid waste is processed for chemicals such as phosophorous for fertilisers, and solid waste is processed to create "biogas" to replace natural gas for cooking.
Wang Jing-Yuan, of Singapore`s Nanyang Technological University (NTU), said: "With our innovative toilet system, we can use simpler and cheaper methods of harvesting the useful chemicals and even produce fuel and energy from waste."
Flushing takes up to 90 percent less water than a conventional loo.
The loo took 18 months to develop and, following trials in restrooms, people could be sat on it within three years, the newspaper said.
The loo is due to be unveiled at a convention in Singapore next week.
