If only we could harness all of that waste that gets flushed down the toilet drain. Well, things are looking pretty promising as far as harnessing human waste goes. Scientists from Singapore’s Nanyang Technological University have developed a toilet that uses 90% less water than other toilets AND it is capable of generating energy.
It is called the No-Mix Vacuum Toilet and it divides waste into liquids and solids. It works by using vacuum tech similar to airline lavatories. It flushes solid and fluid wastes with 1 and 0.2 liters of H2O, respectively. Then it sends refuse to external processing facilities.
At that point, fertilizer ingredients such as nitrogen, potassium and phosphorous are harvested from the liquids. Even methane can be harvested from solids for conversion into electricity or as a replacement for other natural gasses. This is some seriously impressive potty tech here. In fact, two of the university’s restrooms will soon have the toilets installed and they are hoping to roll out worldwide within the next three years.
