I'm currently doing a three-bin system for the kitchen scraps and yard waste (with some added horse manure to get things going whenever I fill up a new bin). That one actually gives me some amount of compost I use in said yard again.

Three months ago I also started a wannebe-Johnson-Su like bioreactor, so a cylinder shaped pile of shredded leafs and wood chips. It's only 80~90cm in diameter and roughly 1m high so nowhere close to the actual Johnson-Su design, but it's what I could make with the leafs/wood and the materials I had lying around.

Lastly I've got a very small vermicomposting setup, a bucket with the bottom cut out and some thick wire going back and forth for the bottom. This is more of a small scale continuous flow setup, which I have not harvested yet. Not too sure whether this thing is gonna work out, to be honest.
