Hi all.
Still developing our our offgrid ecolodge in northern Indonesia,  and experimenting with different designs for composting toilets.
We are following the principles and designs from Jenkins' humanure handbook,  and following solid advice we've received on this forum.  We've built a humanure hacienda,  and it's all working really well.
The problem is that we're a resort not a family home,  so there will be many composting toilets which fill buckets quickly.  Even with the handful of volunteers we have over here, emptying the toilets is becoming more regular and harder work.  Since we stopped separating urine,  buckets have become much heavier.  
Then recently I've seen people using wheelie bins. This is very appealing to us.  Are there any good reasons why using a wheelie bin in conjunction with a large 'hacienda' style compost bin would not be effective? Perhaps the longer duration of time the guests' deposits stay in the wheelie bin rather than the hot composting area has an effect on the process,  or the length of time the compost needs before it can be used in soil?
Hopefully not,  and we can start building our prototype right away!

I hope you'll share the building process with us here. I'm interested to see how it goes.

A while ago I searched on Permies for "willow feeder" because I didn't know what it meant, but this is what the Wheaton labs community are calling their wheelie bin system and there is heaps of information here about how they go about dealing with humanure on a community scale.

Milkwood also have information on their site about how they use wheelie bin compost loos to deal with humanure from lots of people: https://www.milkwood.net/2010/11/23/the-most-lovable-loo-in-the-west/

This is great.  The link is a place with exactly Our challenge.  They are just leaving the wheelie bins in the sun for a year though,  which would mean we would need to buy many wheelie bins.  Can't I empty a full wheelie bin into a humanure hacienda, clean and reuse straight away? Would need some kind of pulley system to lift the heavy bin and flip it,  but that might be a fun project.

In theory you could treat it like a giant bucket in that way, but because it gets riskier with pathogens, parasites, etc when you have lots of different people using it, many of those that use theirs for courses and events leave it sitting for a year as an extra precaution.

Nature Loo told us to leave ours 6 months at above 15 or 18°c though, so maybe with higher temperatures it takes less time.
