Researchers in the U.S. say they have created an ultra-slip toilet cover that can help save huge amounts of water around the world.
Scientists at Pennsylvania State University say coating reduces the amount of water needed to flush excrement by 90%.
They say that it also prevents the accumulation of bacteria in the toilets and reduces the odors associated with them.
The spray, which is more slippery than Teflon, will be dependent on urine and must be reapplied after about 50 rinses.
Researchers hope the discovery can help reduce waste. More than 141 billion liters of water are used daily to flush toilets.
- Water bill too expensive to flush the toilet
- Public toilets are “absolutely necessary,” politicians warn
According to researchers who published their findings in the journal Nature Sustainability, the fresh water used to flush toilets in the world daily is six times the total water consumption in Africa.
“Our team has developed a strong bio-inspirational, liquid, dirt-repellent and bactericidal coating that can essentially make the toilet self-cleaning,” said Tak-Sing Wong, associate professor of engineering at Penn State News.
“Sticking to the toilet is not only unpleasant for users, but also causes serious health problems,” he said. “Our goal is to bring effective technologies to the market so that everyone can benefit,” he added.
