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

Scientists in the United States say they have created an ultra-smooth toilet cover that can help save large amounts of water around the world.

Scientists at Penn State University say the coating cuts 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, will be affected by urine and will need to search again for about 50 rinses.

Researchers hope the discovery can help reduce water waste. Every day, more than 1[ads1]41 billion gallons of water is used to flush toilets.

  • Water bill & # 39; too expensive & # 39; to flush toilet
  • Public toilets & # 39; absolute necessity & # 39 ;, politicians are warned

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

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

"Poop sticking to the toilet is not only uncomfortable for users, but it also causes serious health problems," he said. "Our goal is to bring powerful technology to the market so everyone can benefit," he added.
