The Can O Worms is pretty compact. It takes up as much room as a black bin but is shorter. I did get a bit fed up with mine though as I was already using a compost bin and this was producing compost much faster than the wormery. Plus, my worms kept crawling into the sump at the bottom and drowning if I didn't get them out every day! ::) So, I ended up putting my worms into the compost bin. I have two compost bins, so I used to keep orange peel etc that worms aren't fond of out of the one with worms in, but now I don't bother separating the scraps as I have noticed composting worms have found their way into the other bin and they don't seem to mind the citrus peel.
