Scientists from the Nanyang Technological University (NTU) to develop a new toilet that can turn human waste into electricity and fertilizer. Improved watering system, so as to conserve water usage.

Called the No-Mix Vacuum Toilets, 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 liter of water while flushing solids require just one liter.
Two containers are prepared for the sort of solid manure and liquid manure. Of storage containers, solid waste flowed into the bioreactor. Is able to suck up biogas plants such as methane stored in human feces.
This flammable gas can be used to power electricity. "Human manure can be converted into useful material. This is a big advantage," said researchers from the School of Civil and Environmental Engineering, Chang Wei-Chung.

In addition to creating an electricity, solid waste can be converted into fertilizer. Some of the material in the feces as nitrogen, phosphorus, and potassium can indeed be used to fertilize the soil after further processing.
Researchers also pinned dirt suction system. This system uses less water. Consequently, the toilet only need a cup of water to flush the dirt. "The use of water could save up to 90 percent," he said.
Wei-Chung said the lack of natural resources in Singapore to make researchers think seriously how to utilize the waste into useful things. In July, two cardboard toilet Wei-Chung will be installed at the NTU campus. A total of 500 students will be the first users of this toilet as well as a tester.
After that, the toilet will be installed in a city to be tested by a resident for two years. If testing goes well, two and a half years later, the Singapore government will export this multifunctional toilet to various countries. *** [SCIENCEDAILY | ANTON WILLIAM | KORAN TEMPO 3923]
