Building a better composting toilet
This week, I've written about
like the Clivus Multrum (easy to use but not as safe) and Joseph
Jenkins' thermophilic composting system (more time-consuming but
producing vegetable-garden-safe compost). Today, I'd like to
mention two systems that seem to combine the best of both worlds.
The first system isn't
one I've actually seen online, but it seems to be an obvious upgrade to
Jenkins' Humanure Hacienda for those of us who don't mind cold
butts. Why not simply make a platform above each composting bin
and deposit your waste directly? Presumably, the slatted bin
sides and the addition of straw or hay and food scraps would still
prompt the pile to heat up, and there'd be no need to handle poop.
A design that's already been
tried out is Milkwood's
rollie bin composting toilet. This Australian farm
brings in a lot of students and interns, so the proprietors didn't feel
comfortable handling strangers' waste. Instead, they built a
raised outhouse that dropped humanure into a rolling trashcan.
When the first can filled up, it could simply be rolled out of the way
to compost in the sun for a year while a new can took its place.
What kind of interesting
composting toilet have you come up with? I'm very curious to hear
from anyone who's designed a thermophilic humanure composting system
that's not based on Jenkins' design.
