Disposable Toilet To Change the World

captn ecks writes "A biodegradable and self-sterilizing bag for people of the toilet-disenfranchised world (40% of humankind) to dispose of their bodily waste and turn it into safe fertilizer has been created by a Swedish entrepreneur. It's a dead simple and brilliant solution to a vexing problem. From the article: 'Once used, the bag can be knotted and buried, and a layer of urea crystals breaks down the waste into fertilizer, killing off disease-producing pathogens found in feces. The bag, called the Peepoo, is the brainchild of Anders Wilhelmson, an architect and professor in Stockholm. “Not only is it sanitary,” said Mr. Wilhelmson, who has patented the bag, “they can reuse this to grow crops.”'"

  1. Why don't they build themselves a sewer system by Spy+Handler · · Score: 4, Interesting

    ok these bags may be better than the current method but it's still pretty much a band-aid solution. It's hardly going to "save the world".

    What I don't get is, why doesn't Kenya and all these other 3rd world countries build a real sewer system? It's not rocket science; the Romans did it over 2000 years ago using nothing but hand tools, rocks and some volcanic cement. Yes it was labor intensive, but AFAIK labor shortage isn't a problem in most 3rd world countries, is it? Besides they should be able to get access to some heavy diesel equipment on loan through UNICEF or World Bank or some such organization.

      why doesn't Kenya and all these other 3rd world countries build a real sewer system?

      Way to wait till someone invents a simple solution, to come up with an even simpler solution!

      Also... I heard that a lot of people don't even have bread to eat. Why don't they just eat cake?

      "Why don't they just" is a good solution to having the poor pull themselves up out of poverty by their bootstraps, but there are a lot of interrelated problems keeping them down, that need to be solved first (or simultaneously) in order to allow building infrastructure to pay off. It's worth trying to tackle, I think, but I also think that a few thousand dollars worth of bags that turn disease-producing waste into fertilizer would go a LOT further than the same money spent on heavy diesel equipment.

      Also keep in mind that much of rural north america isn't fit with a sewer system, and if it's not feasible here it certainly isn't in rural parts of the third world. A sewer system isn't a solution for all parts of the world.

  2. Perhaps a buy one donate several model? by ravenscar · · Score: 5, Interesting

    It would be interesting to see a corporate model that allows these items to be sold to the hiker/camper crowd in the first world with revenue for those sales being used to donate the bags to places with a need. For example, I could easily see the Seattle area yuppie hiker crowd paying $10 for three bags at REI. Let's say it costs $5 to produce, package, import, market, and retail these bags. $4 of the remaining $5 could be used to produce more bags and donate them to international aid organizations.

  3. Shit provides both food and fuel by Colin+Smith · · Score: 5, Interesting

    e.g.

    You get methane which can be burned as fuel and the digestate is high in nitrogen, phosphorus and calcium.

    Alternatively, lower tech without the gas tight fittings, drop the methane capture idea and use a dry toilet. It's more a matter of education and organisation than anything else.

    I'll just point out that by not doing this in the west, we are effectively extracting phosphorus, nitrogen and calcium from our fields and pumping it into rivers and oceans. We then burn a load of fuel to dig up more phosphorus and calcium elsewhere and burn natural gas to produce nitrates to put back on the fields. It's dumb.

  5. Could also be used after earthquakes or tornadoes by Rick17JJ · · Score: 3, Interesting

    The disposable toilets could also be used after disasters such as earthquakes, floods, hurricanes or tornadoes. It also might be useful for homeowners to use during a several day long power outage after a wind storm or an ice storm. It would be an alternative to grabbing a shovel and going in the back yard or on undeveloped land nearby.

    Baby wipes or similar disposable disinfectant wipes could be used to clean the person's hands afterwards, if no working water faucet is available. I sometimes use a baby wipe for my hands after using a Clivus Multrum composting toilet or an old pit toilet in the national forest, where no running water is available. I usually keep several in my day pack when hiking, just in case. The baby wipes could also be used on overnight backpacking trips when camping where no running water is available.

    As a child, I remember visiting a several older relatives such as my grandparents, who had an outhouse on each of their farms. Grandpa's was a three hole outhouse. If I remember correctly, they had a small bucket of lime and would sometimes sprinkle a little over the poop. There was also some corn cobs and an old Sears catalog, just in case they ever ran out of toilet paper. If I am not mistaken, the corn cob is supposed to be used together with a page from the Sears catalog. As a child, I also enjoyed using the hand operated pump for pumping water from the well.

    Of course they did also have one toilet and running water in the house, but as a child I found it more interesting to use the outhouse and the hand pumped well.

  6. Re:What does a toilet have to do with voting? by GasparGMSwordsman · · Score: 3, Interesting
    When you actually understand the English language and use its rules, you quickly see that many words are simply modifiers on a base word. Here we have the base word "Enfranchise" with the addition of a negative modify "dis" and a past tense modifier of "ed".

    The results is Dis*Enfranchise*d. The definition of the word is similarly reflected by modifiers. We take the root word, negate it (as in make it negative or opposite to the original meaning) and also state that the subject it is referring to has already happened (as in the past).

    The definition Enfranchise according to Merriam-Webster is as follows:

    Main Entry: enfranchise
    Pronunciation: \in-fran-chz, en-\
    Function: transitive verb
    Inflected Form(s): enfranchised; enfranchising
    Etymology: Middle English, from Anglo-French enfranchiss-, stem of enfranchir, from en- + franc free -- more at frank
    Date: 15th century

    1 : to set free (as from slavery)
    2 : to endow with a franchise: as a : to admit to the privileges of a citizen and especially to the right of suffrage b : to admit (a municipality) to political privileges or rights

    Source:
    http://www.merriam-webster.com/dictionary/enfranchise

    The first definition, "to set free" is simple enough. The second definition is simply one who has received a Franchise (our subject is a group of people after all), so let us examine the definition of Franchise. In essence, it is a right to something. (The etymology of the word is interesting, its base having the meaning "free".)

    So back to analyzing the summary:

    If we assume the summary refers to those people who have no access to a toilet then the definition does match the usage of the word. In addition if you have no alternative other than using a toilet (or perceive no alternative) then the word would be correct in its usage. In either case the word would be correct in usabe bacause the person(s) are certainly not free, they are constrained in either choice or action.

    If we assume the usage is to apply to those who don't *like* toilets and would prefer an alternative then the word is misused.

    I would recommend reading a book of grammar and the rules of the English language before commenting on the meaning of words. I would also recommend that you stop assuming that you know exactly what group of unnamed people a speaker or author refers to.

    I am sure you have heard of the saying about what happens when you assume things. =)

    It's not that they don't have access to birth control (well, some don't, but...), it's that many/most people in those places don't necessarily want it. Change attitudes about that and they'll do a lot to get their own birth control. Otherwise, giving away a bunch of free rubbers just translates into amusing balloon tricks for the impoverished world.
