Why Worms In the Toilet Might Be a Good Idea 124

derekmead writes "Billions worldwide still don't have access to proper sanitation, and those that do still require a ton of water and electricity to keep waste flowing. A French company is offering one solution: Use turd-eating worms to compost waste right at the source. Ecosphere Technologies has developed an outhouse that, rather than relying on chemicals like a port-a-john, relies on about a pound of red wiggler worms. A new installation in Quebec uses imported worms, placed inside of a mixture of dung and straw underneath to toilet, to devour feces delivered to them by a conveyor belt system. (When someone uses the toilet, pee filters through sand to wash away, while a pedal allows the user to transport their poo to the worm space.) The whole system uses no water or electricity, and a series of passive vents allegedly keeps the toilet smelling great. The company claims it can be used 10,000 times without servicing, which is far better than what a port-a-potty can boast, although with a current price tag of $40k for the worm system, port-a-potties are still a lot cheaper."

      I'd also just point out that earthworms eat the shit in outhouse pits when the uses don't dump a ton of lime into it. All the outhouses need is solar powered positive pit ventilation.

          It's bad enough when the waste pump on a boat toilet needs fixing - at least that thing's mostly a small sealed unit with just a couple of hoses clamped on. That's one conveyor belt that you'd want to make sure was damned reliable and never ever needed repairs rr maintenance on - it's going to be one hell of a nasty job if it gets so crusted up it can't move or the bearings go or something like that.

          • That was actually my first thought as well. Also, from what I understand it is just a composting toilet which are not all that complicated or expensive. The only innovative thing seems to be the poo-conveyor. Maybe that is why it is so expensive... $35k for the super fuckin' reliable conveyor, $5k for the rest.

          This problem has been solved before - In Ye Olden Dayes a common technique was to have your outhouse in the center of a copse of coppiced trees (willow being one of the preferred species due to it's particularly "hungry" roots), which would then convert your waste into firewood while cleaning out the pit for you. Unfortunately then as now mixing liquid and solid wastes produces a fairly toxic mass that's harmful to most life. So what was the solution? Some contrived conveyor system? No - they just put a catchment basin just beneath the front of the seat to catch liquids and redirect them under the trees at the surface. Sure, women had to pay a bit more attention to their aim, but the system was nice and simple with no moving parts to go wrong, and the trees were perfectly capable of dealing with both kinds of waste as long as it wasn't mixed together.

    Perhaps this is too expensive to replace the portable restrooms in developing countries, but perhaps this could be used in larger-scale applications to help deal with the solid waste in waste treatment facilities? Instead of using harsher chemicals, we could augment it with more biological processes such as this to increase the efficiency of the treatment. Just a thought anyway.

      The worms aren't necessary, and neither is the $40k price tag. There are already composting toilets [wikipedia.org] available commercially in the $500-$2000 range. And even that's overpriced because they're relatively new. I've heard of people making their own with a 5 gallon bucket (cheapest way to test for yourself how well they work). All you need is a handful of peat moss or coconut husk, and a spoonful of microbes to get the process started.

      And before you ask, no they don't stink. The stinky smell comes from anerobic bacteria breaking down fecal matter. When you immerse feces in water, it cuts off the oxygen supply which kills the aerobic bacteria, and the stinky anerobic bacteria flourish. Because a composting toilet channels liquids away from the solids reservoir (the 5 gallon bucket works better for men), the aerobic bacteria dominate and break down the feces without causing the stink. Think about how much biomass there is outdoors in wild animals. If all their feces stank that badly as a sewage treatment plant, we'd never want to go outside.

      They're starting to become popular aboard boats, where dumping laws require toilets flush into holding tanks which can to be pumped out back at the harbor. These holding tanks and their plumbing tend to leak and stink up the boat after some years.
      • by slashmojo (818930)

        Yes exactly, compost toilets have been a fairly common choice amongst boaters for a while now and not much more expensive than the usual boaty alternatives plus they require less holes in the hull which is always a bonus on a boat. Of course you still need somewhere to dump the compost as marinas are not generally very green and tend to frown upon compost heaps springing up around the pontoons.
