Composting toliet trailers / mobile bathrooms / and best composting humanure ideas / threads

Hi friends and permies,

I am seeking this thread or article Paul posted a while back about his composting trailers/ composting bathrooms they have built for events and so forth, can someone help me find that thread/article/posting??? They were so cool and we are looking to do something like that. For the record I would also be open to buying something like that... but we can build it. Can anyone help link?

While im at it can folks please post the best threads on composting toliets, especially mitigating smell with the least electricity as possible?

We have been humanure composting about 7 years and use sawdust/biochar as our medium in a tub (human kitty litter box basically). I have been supplementing with an EM1 type spray to help keep the microbes smelling good and the smells reasonable in the bathroom. Im looking for more, for instance, good ideas on microbe sprays in the bathroom, best carbon mixes, and best clever mechanical systems for composting toliets. At one point I saw this awesome rotating carosel design there are many out there, please share the best threads or links you've got thanks permies.

Love,
Nom
