Many things are structured around distancing us from waste. One example I can think of is sanitary disposal boxes in the  public bathroom.  After one has used a sanitary napkin  and needs to dispose of it they are able to put it in a little brown paper bag inside the metal waste receptacle in the bathroom stall. Keeps the biological waste away from other people that have to use the stall and makes it more discreet as they are able to not throw it away outside of the individual stall which can sometimes be embarrassing for some people.  In many men’s bathrooms those  receptacles aren’t there  which can create some frustration for those who need to use those bathrooms but menstruate.  These receptacles provide a place to dispose of waste that is in general in society seen as shameful or embarrassing. where a lot of people will be very embarrassed if their pad rapper crinkles while they’re trying to unwrap it and it’s a shame that periods and menstruation is so Vilified when it’s a natural biological process that nearly half the population has.
