Hi all,
We're building an off-grid beach resort for budget travellers in Central Sulawesi, northern Indonesia. And yes, it's right where the Earthquake and Tsunami were, but we're fine and the
project continues.
Each of our bungalows will feature a composting toilet. As we're still in the build stage we need to make sure we get the design for the toilets right, and the process for using the organic matter correct, from the beginning.
Currently we have a simple 'bucket-in-a-box with a seat on top' system set up as a trial. We have a
urine diverted installed, and use mostly sawdust for to cover each deposit. We figure that paying guests would prefer this kind of system to one where you poo into a large container which takes months to fill and takes up more space.
How are we doing so far?
Then, to recycle the contents of the buckets, we plan to leave them in the hot equatorial sun to dry out for a couple of months. Then, we have built 1.5m3 composting boxes. We will layer up with plenty of browns and greens and bacterial activators, leaving a 'nest' in the middle for a few buckets of the dried toilet material. We'll then Close it all up, ensure that thermophillic composting is taking place and that the inside of the pile is nice and hot for a while, then start turning.
Are we going down the right path here? Realistically for how long
should the
humanure be left in the
compost pile before turning/ using the compost to ensure all of the pathogens are dead?
Right now we're only producing a couple of buckets of poo each month as it's just the owners, craftsmen and volunteers on site. But when guests start arriving we will have much more, so we need to get these systems correct from the beginning.
Any advice very much appreciated!
Thanks
