Exactly, this is what I was getting at too. Mine was bought via the council for about ten quid.
OP, these "tardis" type compost bins are just a plastic bin which you place on the ground. When you want to add stuff, you lift the lid to do so. The lid stays closed so you don't get flies. After several months, the compost is made and you lift a Shute at the bottom to take out as much as you need.
It's the size of a dustbin and it's a really handy thing. Instead of putting my half bucket of chicken poo in a waste bin, I put it in my compost bin. Same process - lift lid, dump, close lid - but the difference is that you get something useful at the end of it! Mine doesn't smell or attract flies at all.
But as I said before, if you're still dead set against a compost bin then just throw the droppings away, I guess.
