#toilet coating

Worldwide, billions of people lack access to adequate toilet facilities, leading to many sanitation-related illnesses and deaths. Water scarcity plays a significant role in this, as many low-resource environments are not able to clean and maintain their toilets.

To design more sustainable toilet facilities, Penn State researchers have developed an ultra-slippery coating for the inside of toilet bowls to keep waste from sticking. While most research aims to create high-tech solutions, this coating is a simple way to half the amount of water needed by toilets.
