I put them in the bin, however, toast lover, you should not put them down the toilet, they only have to be filtered out the other end, thats if they dont get stuck first, and cause a build up upstream, then when they have been removed, they have to be sent for disposal, so this causes more cost and handling, and potential contamination than sticking them in the bin, so please, from a plumbers point of view, put them in the waste bin, thanks,
