Bio hazard or not?

Makhaila • -M.
My friend brought up a good question that I want to ask. Whenever you get blood on anything it's considered bio hazard and thrown in that bin not the trash, but everyone is perfectly okay with women throwing used pads/tampons in the trash, when that is clearly covered in blood. Why is this? Why don't we have to put our period stuff in the bio hazard bin when everything else with blood goes in there as well???
