Introduction
Used razor blades are still dangerously sharp and can cause serious injury if thrown away without precautions. Stainless steel and carbon steel blades can be recycled, but most importantly must be isolated from the possibility of harming others.
Blades can be wrapped in the paper they were shipped in, or in several layers of paper; but this method is far from foolproof and is not particularly convenient. Blades can be inserted into the bottom portion of some plastic blade dispensers; but again, this method is not particularly secure unless the plastic dispenser is taped shut.
Used razor blades may be considered medical waste; it may be useful to consider them as such when examining the possibilities for disposing of used blades. Check with your local government regarding laws and ordinances regulating disposal/recycling of used razor blades.
