Our local council won't take them, the chemists won't take them, so we are told to return them to the GP surgery. Only problem is I keep forgetting. We did it just the once when my son had to see our GP and he looked at me somewhat bemused when I asked if he could see to the disposal of it, but took it all the same. Now have about 6 more lined up in the garage. I must remember and take them down sometime. How big are all your sharps bins? Ours are only 1 litre and my son fills them up in no time, hence the collection! I wish we had decent size buckets, though I suppose that would take up more space in his room......
