The wire under the bin to deter vermin is a brill idea.
There is a new type of bin that I saw on the recent compost course; a 'hot bin'. It is £129, gasp, I understand it is being made by one guy in a shed, so hopefully the price will come down when Dragons Den or similar fund him. It is made from very sturdy polystyrene type material, it is 3 or 4 cm thick, about the size of a domestic wheely bin. The heat enables you to put in ALL kitchen waste as far as I understand. I have seen it for sale in some catalogue also.
