I've always put them in my outside bin but at First Aid training at the weekend we were told we should be treating them as clinical waste and putting them in a yellow bin and paying the council to come and collect them.
Either that or send them home with the parents so they can put them in their own bins.
Anybody else heard of this? I have no idea where I'd put a clinical waste bin anyway - not prepared to have it in my house for up to two weeks at a time, can't have it in the garden as accessible to mindees and I'm certain I wouldn't be allowed to keep it in the street!
