Scientists from Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing byup to 90 per cent compared to current toiletsystems in Singapore.
Dubbed the No-Mix Vacuum Toilet, it has two chambers that separate the liquid and solid wastes. Using vacuum suction technology, such as those used in aircraft lavatories, flushing liquids would now take only 0.2 litres of water while flushing solids require just one litre.
The existing conventional water closet usesabout 4 to 6 litres of water per flush. If installed in a public restroom flushed 100 times a day, this next generation toilet system, will save about 160,000 litres in a year – enough to fill a small pool 10 x 8 metres x 2m.
