Very interesting, especially the bit about not putting the compost on fruit and veg.
It's a shame it's so expensive, but sounds like a clever product. I'm not sure I'll be able to make something so good, but I'm going to give it a shot!
I had a thought earlier, and that is that in Sainsburys (I think) they have degradable nappy sacks, so in theory you could pick up the dog poo if you were out and about as usual, and fling the lot, bag and all, into the wormery. My next thought is that councils should do this in parks - there's nothing more repulsive than overflowing dog poo bins. One lovely walk near here has the most horrible thing ever - some cretin goes to the trouble of collecting the dog poo in a bag, then hurls it up into the trees. In the winter it's like a dog poo tree. Shudder.
