Scientists Develop Toilet System That Can Turn Waste Into Energy
Scientists from Singapore’s Nanyang Technological University have recently developed a toilet system that uses 90% less water than others and is capable of generating energy. Named as the No-Mix Vacuum Toilet, the porcelain pedestal’s pot divides waste between two partitions with one side for liquids and the other for solids. Flushing fluid and solid wastes with 1 and 0.2 liters of H2O, respectively, the can will be able to route refuse to external processing facilities.
Fertilizer ingredients such as nitrogen, potassium and phosphorous can then be harvested from liquids. Methane can also be extracted from solids for conversion to electricity or as a replacement for other natural gasses. Two of the university’s restrooms have been assigned to have No-mix vacuum toilets installed in the near future.
The team behind this project expect that the new toilet system will spread around the world within three years.
