This is Steve‘s bin that I mentioned in my last post.

Glasdon UK: Plaza® Litter Bin

Had to be drunk proof, dustman proof, and bomb proof.  Also has to be emptied without needing a key, but be difficult to open if you don’t know how (to prevent Saturday night vandalism).  To top it all had to be designed to be able to be replaced after emptying so that it self locks, and yet is made by a moulding process that means there may be up to a couple of centimetres movement from the design spec.  I am very impressed.
