Bill Gates put a new meaning to pitching when he showed up with a jar of poop while hosting the ‘Reinvented Toilet Expo’
The expo was dedicated to paving the way to create self-contained toilets that do not need water or sewers.
‘Today, rich countries have a sewage system where you bring water in, put the human waste in it and it goes out to all the way to a treatment processing plant,’ Gates said.
‘That requires the installation of a lot of pipes. It’s very expensive and it’s not gonna happen in these newer, poorer cities.’
According to the WHO, around 2.3 billion people still do not have basic sanitation facilities such as toilets or latrines.
Gates pointed out the jar in his hand could contain ‘as many as 200 trillion rotavirus… 20 billion shigella bacteria and 100,000 parasitic worm eggs.’
Lack of clean sanitation comes at a staggering financial cost — The Gates Foundation estimates $223 billion a year in the form of higher health-care spending and lost productivity and wages.
Through the Gates Foundation’s ‘Reinvent the Toilet Challenge,’ Bill and Melinda Gates have funded teams seeking to develop waterless toilets over the past seven years up to the tune of $200 million.
To compete in the challenge, toilets had to cost less than 5 cents a day to operate, without the need for external electricity or running water.
The foundation funded scientists to invent toilets that are self-contained — they take human waste, kill dangerous pathogens and convert the resulting material into products with potential commercial value, like clean water, electricity, and fertilizer.
Gates chose to sell his pitch in a country that has struggled with clean sanitation. In 2015, Chinese President Xi Jinping called for a national ‘toilet revolution.’ The world’s second-largest economy since 2010, China has made significant improvements in public hygiene, but many rural towns still do not have access to modern toilets.
Gates acknowledges the production of these toilets is in its beginning phases and it would take at least a decade before reinvented toilets reach the masses in the poorest areas.
‘The very first ones are still fairly expensive. It’s gonna take time before we get the volume to really take down to the low end of the market,’ Gates said.
‘But this is how we bootstrap it, and we got a lot of enthusiasm here that this can be made cheap enough that we can cover Africa, which would not happen without this breakthrough.’
