BEIJING — Bill Gates believes the world needs better toilets.
Specifically, toilets that improve hygiene, don’t have to connect to sewage systems at all and can break down human waste into fertilizer.
So on Tuesday in Beijing, Mr. Gates held the Reinvented Toilet Expo, a chance for companies to showcase their takes on the simple bathroom fixture. Companies showed toilets that could separate urine from other waste for more efficient treatment, that recycled water for hand washing and that sported solar roofs.
It’s no laughing matter. About 4.5 billion people — more than half the world’s population — live without access to safe sanitation. Globally, Mr. Gates told attendees, unsafe sanitation costs an estimated $223 billion a year in the form of higher health costs and lost productivity and wages.
The reinvented toilets on display are a culmination of seven years of research and $200 million given by the Bill and Melinda Gates Foundation, which the former software tycoon runs with his wife, since 2011. On Tuesday, Mr. Gates pledged to give $200 million more in an effort get companies to see human waste as a big business.
