 Microsoft founder Bill Gates presented a container of feces (排泄物)to visitors to a trade show in China. No, not the China International Import Expo in Shanghai. Gates is at the “Reinvented Toilet” Expo in Beijing to discuss developing a safe process to remove human wastes.
 
“You might guess what’s in this beaker_and you’d be right. Human feces,” the Microsoft founder told the gathering. He said, “This small amount of feces could contain as many as 200 trillion rotavirus cells, 20 billion Shigella bacteria, and 100,000 parasitic worm eggs.” Gates noted that these microbes cause diseases that kill almost 500,000 children under the age of 5 every year.
 
More than 20 companies and research organizations are showing new toilet technologies at the three-day expo. These include self-contained toilets, a small self-powered waste treatment system called the Omni Processor and other inventions. The Bill and Melinda Gates Foundation presented its own idea for a future toilet that does not require water. Instead,it uses chemical to turn human waste into fertilizer. There are several designs of the toilet but all work by separating liquid and solid waste. “The current toilet simply sends the waste away in the water, whereas these toilets don’ t have the sewer (下水道).They take both the liquids and solids and do chemical work on it, including burning it in most cases,” Gates told Reuters. He compared the development of waterless toilets to that of personal computing in the mid-1970s.
 
The researchers are planning to show the waterless toilets to producers. Gates said he expects that a more than S6 billion market for the toilets will develop by 2030. The Bill and Melinda Gates Foundation has spent more than $200 million since 2011 to support research and development of safe sanitation technology.
