Scientists and researchers at the Singapore’s Nanyang Technological University (NTU) have been working since 2010 to make towns and cities more sustainable by taking waste from housing and turning it into energy.
Dubbed as Toilet 2.0, the ‘No Mix Vacuum Toilet’ is an aeroplane-style vacuum toilet which splits waste into solids and liquids. Liquid waste is processed for chemicals such as phosphorus for fertilisers, while solid waste is processed in a bioreactor to create ‘biogas’ – a methane-rich gas which is, the scientists promise, odourless and safe for cooking.
The toilet system is currently being tested in the University itself since July this year.

Other than generating electricity and fertilisers, the “No Mix Vacuum Toilet” can also reduce water for flushing by up to 90 per cent. According to the inventors, if it is installed in a public restroom and flushed 100 times a day, it will save 160,000 litres in a year – enough to fill a small swimming pool.
If you happen to visit the Singapore’s Nanyang Technology University, do let us know if you manage to try the “No Mix Vacuum Toilet”.
