One Man's Trash is Another Mans...Trash

Living on campus there is one chore I know is a constant, taking out the trash.  However, this is true for everyone no matter where you live. Trash is a part of our daily lives. It is something that we accumulate in mass every day. I work in the scene shop at the theatre we have three large trash cans which we fill by the end of each week with scraps of wood, metal, and other building materials. We have a large industrial-size trash bin that gets dumped once a week, and it is normally full by mid-week. Last week I made a comment on the amount of litter on campus, and this week I wanted to try to find a cause for the litter. One big thing I hit on is there are a lot of trash cans on campus, but many of them are full by mid-week. I am not talking about the trash cans that are inside buildings, for those are dumped nightly, but the ones around campus.  There are only a handful of trash cans on the campus grounds itself, many of them are right outside buildings, however, many of them are always full.  I think there is a correlation between the litter on campus and the full trash cans. I want to ask about when the cans on campus are dumped because it does not seem like in is often enough. I also think there could be more trash can on campus. I know that both options will cost money, and that could raise tuition, however, something must be done.
