Why Worms In the Toilet Might Be a Good Idea

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."

      The worms aren't necessary, and neither is the $40k price tag. There are already composting toilets 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.

      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.

There is even a specific jÅkasÅ law that regulates their construction, installation, inspection and desludging. JÅkasÅs use different technologies and serve different sizes of buildings from single-family homes to high-rise buildings, public or commercial buildings. Treated water can be easily reused for various purposes such as toilet flushing, watering gardens or car washing. Sludge from jÅkasÅs can be used as fertilizer

    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.
