Scientists say that the fresh water used to flush the world's toilets every day is six times Africa's total consumption

Researchers in the United States say they have created an ultra-high quality toilet coating that can help save large amounts of water around the world.

Researchers at Penn State University say that the coating reduces the amount of water needed to flush excrement by 90%.

They say it also prevents bacteria from building up in toilet bowls and reduces associated odors.

The spray, which is more slippery than Teflon, would be affected by urine and must be reapplied after about 50 rinses.

Researchers hope the discovery can help reduce water waste. Every day, more than 141 billion gallons of water is used to flush toilets.

According to the researchers, who published their findings in the journal Nature Sustainability, the fresh water used to flush the world's toilets every day is six times Africa's total water consumption.

"Our team has developed a robust bio-inspired, liquid, sludge and bacteria repellent coating that can essentially make a toilet self-cleaning," Tak-Sing Wong, associate professor of mechanical engineering at the university, told Penn State News.

"Poop that stays at the toilet is not only uncomfortable for users, but it also presents serious health problems," he said. "Our goal is to bring impact to the market so everyone can benefit," he added.
