Researchers in the US said they have developed an ultra-slippery toilet coating that could help save huge amounts of water around the world.
Penn State University scientists report that the coating lowers the amount of water required to rinse excrement by 90%.
It also prevents the accumulation of bacteria in toilet bowls and reduces the associated odors.
This is slipperier than Teflon, it would be infested with urine and needs to be reapplied after about 50 flushes.
The researchers hope that the discovery could help to reduce water wastage. Every day, more than 1
- Water bill "too expensive" for toilet flush
- Public toilets "absolute necessity", politicians are warned
According to the researchers who published their findings in the journal Nature Sustainability, the fresh water is used to flush the toilet Toilets in the world use water in Africa six times a day.
"Our team has developed a robust, biologically-inspired, liquid, mud and bacteria-repellent coating that can essentially make a toilet self-cleaning," said Tak-Sing Wong "Sticking to the toilet is not only unpleasant for users but also raises serious health concerns, "he told Penn State News, a professor of mechanical engineering at the university. "Our goal is to put effective technologies on the market that everyone can benefit from," he added.
