Gates Foundation Spent $200 Million Funding Toilet Research (bloomberg.com)

According to Bloomberg, the Bill & Melinda Gates Foundation "spent $200 million over seven years funding sanitation research, showcased some 20 novel toilet and sludge-processing designs that eliminate harmful pathogens and convert bodily waste into clean water and fertilizer." Gates told the Reinvented Toilet Expo in Beijing on Tuesday that these technologies at the event "are the most significant advances in sanitation in nearly 200 years." From the report: Holding a beaker of human excreta that, Gates said, contained as many as 200 trillion rotavirus cells, 20 billion Shigella bacteria, and 100,000 parasitic worm eggs, the Microsoft Corp. co-founder explained to a 400-strong crowd that new approaches for sterilizing human waste may help end almost 500,000 infant deaths and save $233 billion annually in costs linked to diarrhea, cholera and other diseases caused by poor water, sanitation and hygiene. One approach from the California Institute of Technology that Gates said he finds "super interesting" integrates an electrochemical reactor to break down water and human waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells as energy.

The reinvented toilet market, which has attracted companies including Japan's LIXIL Group, could generate $6 billion a year worldwide by 2030, according to Gates. The initial demand for the reinvented toilet will be in places like schools, apartment buildings, and community bathroom facilities. As adoption of these multi-unit toilets increases, and costs decline, a new category of reinvented household toilets will become available, the Gates Foundation said.

    I was once advised by a mentor to 'never skimp on anything that gets between you and the ground'. He was talking about tires, shoes, and beds, but toilets certainly qualify. Every human poops, and many of the worst diseases still extant (cholera and friends) thrive in conditions of poor sanitation. So don't make fun of this research -- respect the throne! Invest in it!

  4. Shit is a real problem by mveloso · · Score: 4, Insightful

    It's interesting to see this sort of research. Getting rid of people's shit is actually quite difficult to do in an efficient and sanitary way. It's also a difficult UX problem, because levels of care in excreting are substantially different across cultures.

    For example, in poor areas the idea of sitting on a toilet seat is a completely alien idea. People either squat over holes in the ground or stand on the toilet bowl and squat. People will occasionally shit or pee all over the toilet, causing problems. Getting the shit/pee out of the bowl along with toilet paper etc is difficult. Then there's the odors/smell/leftover shit problem.

    Plus toilets need cleaning...lots of cleaning. In fact, they're cleaned more often than any other area, generally speaking. And they're still filthy.

    We haven't even gotten to the "moving the shit out of the toilet" part at that point.

    Then of course there's the "what do you do with the combined shit and piss of 50,000 people."

    So kudos for the Gates Foundation for doing something creative with their money. These sort of structural problems get worse as time goes on. People don't understand the sheer amounts of infrastructure it takes to deal with shit like this. Here's an example:

    In NYC, there are about 3 million households. Each household has 2 toilets. Each toilet requires a holding tank of 6 or 13 gallons. So at any given time there are about 18-39 million gallons of water hanging around that had to be delivered to every household. Water pressure is generally 80psi, which means you need 80psi to 3m point locations across 302 square miles (784 sq km). That pressure doesn't just fill toilets, it supplies showers, sinks, washing machines, etc.

    And that's just one municipal water supply. The sewer system is completely independent

    It's surprising, to be honest, that universities or governments aren't looking at these sort of issues. I mean, there are all kinds of efficiencies that are possible. For example, why not use the water pipes for AC heat transfer?

      Having been peripherally associated with some foreign development projects, it’s astounding how many people here completely don’t get that the real problem in many places isn’t getting clean water (though that’s a sexy and easy(er) problem to solve, but rather what to do with the waste at the other end of the problem.

      I’ve supported a couple of charities that do their hardest to build safe, culturally appropriate latrines/privies. These are just as, if not more, critical than drilling wells etc...

    Look to the states that enforce laws and rules about tent cities, RV parking and trash in the street.
    They don't have such problems. Their cities stay clean and attract investment.
    Its a city police politics problem. Find out why the city police do not to enforce laws. Parking laws. Trash laws. Camping laws. Waste laws.

    Yeah, so it turns out pretty much every noncommercial toilet in America is a joke. The seals fail. They just fail. The huge amount of waste that arises from *having toilets with sucky designs in almost every home in the country* is insane.

    The fix is pretty simple: whenever a toilet shows up in a landfill or dumpster, bill the manufacturer.

    We don't do that, so every producer has an incentive to make toilets crappy enough that they fail within a few years.

    Uh, where exactly are you getting your data that confirms we're throwing away toilets every few years? My last house still had the avocado green and harvest gold toilets installed from the 70's (no, I'm not joking), and my current house still has the original hardware that's almost 20 years old. Yes, internal hardware like the flapper breaks down over time (more likely due to the chlorinated water attacking the rubber material), but you don't rip a toilet out of a house because the guts fail. Every toilet I've replaced has been due to something other than breakage (color, height, shape, water capacity, etc.)

    Much like consumer electronics, fashion has put more hardware into landfills than function has.
