If you manage recycling and waste programs in a college town, the student population is your biggest logistical nightmare. Students are itinerant – they roll into town in autumn, pour out again in the spring and disappear entirely a few years later.
This means they’re a lot less invested in the long term health of your city than your permanent residents are; and, therefore, they are less likely to think about proper waste disposal or the benefits of recycling.
Working with student populations can be complex and variable. They may have come from towns with recycling programs different from yours. Depending on their upbringing, they might know little or nothing at all about recycling. They have new priorities, academic and social goals which keep them from thinking about larger community or environmental issues. They might also be facing adult responsibilities for the first time, with varying degrees of success.
