The power of your poo may soon be stored and converted to electricity and fertilizer with an innovative new toilet.
Scientists from Nanyang Technological University have created the â€œNo-Mix Vacuum Toilet,â€ made of two separate chambers that separate liquid and solid waste. That might not sound like anything useful, but one of the most compelling aspects of the new throne is that it reduces the amount of water used per flush by up to 90 percent in comparison to conventional toilets.
A conventional toilet uses about four to six liters of water per flush, but the vacuum suction technology in the No-Mix Vacuum toilet only uses 0.2 liters to flush liquid waste, and one liter to flush solids.
The toilet also turns waste into useful materials. According to NTU Assistant Professor Chang Wei-Chung from the School of Civil and Environmental Engineering, â€œthe new system will not only save water, but the most important thing is we can convert the natural human waste into something very useful, such as the fertilisers, the biogas, energy and electricity as well. So that is the biggest advantage.â€
Associate Professor Wang Jing-Yuan notes that there are considerably fewer natural resources in Singapore than many other places, leading him to wonder how waste materials can be used and turned into usable resources.
The group has been working on the toilet since 2010, claiming there is really no difference between using this toilet and a conventional toilet, other than louder noises than people are used to.
Starting in July, a six-month trial will be carried out with prototypes installed on the NTU campus, where around 500 students will get to try them out. If all goes well with testing and reviews, they hope to commercialize the system and make it available for use in other countries.
