Researchers say the fresh water used to flush world toilets daily is six times the total consumption of Africa

Researchers in the US say they have created an ultra slippery toilet liner that could help save huge amounts of water around the world.

Scientists at the University of Penn say the coating reduces the amount of water needed to rinse off faeces by 90%.

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

The spray, which is more slippery than Teflon, would be hit by urine and need to be repeated after about 50 strokes.

Researchers hope the discovery could help reduce water waste. Every day, more than 141 billion liters of water are used to flush toilets.

  • The water bill is "too expensive" to drop the toilet
  • Politicians warn of the "absolute necessity" of public toilets

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

"Our team has developed solid bio-inspired, liquid, sludge and bacteria that cannot destroy the bacteria, which can essentially do self-cleaning of the toilet," Tak Singh Wong, an associate professor of mechanical engineering at the university, told Penn State News.

"Unnecessary sticking to the toilet is not only uncomfortable for the users but it is serious health care," he said. "Our goal is to bring influential technology to the market so that everyone can benefit," he added.
