Bill Gates lauds futuristic toilets; market to be $6b by 2030
US billionaire philanthropist Bill Gates unveiled on Tuesday in Beijing a futuristic toilet that doesn’t need water or sewers and uses chemicals to turn human waste into fertilizer.
He compared the change from traditional toilets to waterless models as similar to development in computing around the time he founded Microsoft in the mid-1970s.
“In the way that a personal computer is sort of self-contained, not a gigantic thing, we can do this chemical processing at the household level,” he said.
Gates said the next step for the project is to pitch the concept to manufacturers, saying he expects the market for the toilets to be over $6 billion by 2030.
The Microsoft Corp (MSFT.O) co-founder, who a day earlier was one of the high profile guests at a major trade event in Shanghai, also lauded the globalized and free trade systems that made the toilet technology possible.
“I honestly believe trade allows every country to do what it’s best at,” he told Reuters in an interview on Tuesday.
“So when I talk about components of this toilet being made in China, others in Thailand, others in the United States – you really want to be bringing together all of that IQ so that you’re getting that combination.”
The toilet, which Gates said was ready for sale after years of development, is the brainchild of research projects funded by the Bill and Melinda Gates Foundation, the world’s biggest private philanthropy organization.
There are multiple 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. They take both the liquids and solids and do chemical work on it, including burning it in most cases,” Gates told media.
