I don't know much about composting (I've always composted - having lived in collectives/communes most of my life so far - but don't know the science behind it per-se), but I'm about to learn. Because I know I will have a composting toilet in The COMET, I have been looking into more information about composting food waste and humanure.
I've been reading The Humanure Handbook (third edition) which you can find here for free download: http://humanurehandbook.com/
Now that I've decided to build my own composting toilet for The Comet camper and opted not to purchase a very expensive one, I really look forward to reading this book.
I'm hoping to make the most out of a composting toilet/other compost situation on the road by having a "bumper" garden...I'm working on a design for a little greenhouse that mounts onto the back of The COMET.
I've also been reading about worm farms and worm bin composting...there are some great DIY guides out there for making your own cheap worm bin.
This may not be ideal for the mobile lifestyle, but I plan on living in The COMET in some places for extended amounts of time at some point, and it's pretty interesting anyway. Maybe I can get my parents to get a worm bin!
Another composting situation that REALLY appeals to me (and is not perfect for mobile living either, but hey!) is a bunny rabbit compost set-up.
Apparently rabbit poop is really good for compost, and can even be used raw (without going through a composting process at all!).
I was reading about a set-up where there is a compost bin directly underneath the rabbit's coop/dwelling, and the poop just goes right into the compost! I'm not exactly sure how well this works in practice, but it seems like a great idea.
I'd be really excited about a bunny or two...of course they are adorable and I love little animals!
