This is just an observation but one never hears of anyone taking a multi-blade cartridge to a sharps disposal place yet they are just as sharp (X3-5 blades per cartridge) and just as contaminated. On top of that, they have plastic that won't break down. It seems to me that putting used blades in a sealed metal blade bank and then wrapping the blade bank well in masking tape would be safer in a landfill than all of those used Mach-3, Fusion, and Hydro cartridges. I do realize that there are local ordinances which is why this is just an observation. Perhaps many local ordinances do include cartridges in their proper disposal requirements.
