Scientists from Nanyang Technological University (NTU) have invented the No-Mix Vacuum Toilet that turns human waste into electricity and fertilisers and reduces the amount of water needed for flushing by up to 90%.
The system is known as the No-Mix Vacuum Toilet, due to its vacuum suction technology that is similar to those found on aircraft. The toilet system works by having two chambers separate the liquid and solid wastes so that only 0.2 liters (.05 gallons) of water are required for flushing instead of the usual 4 to 6 liters (1-1.5 gallons). If this system is installed in your average public restroom, it is estimated that is would save about 160,000 liters per year (42,267 gallons)!
