For over seven years, the University Book Store has been supporting campus sustainability through its plastic bag recycling program. Although standard plastic bags are banned in Seattle, the University Book Store uses bags made with a thicker plastic, which is allowed. The plastic in the book store bags is at least 2.25 mil thick (one mil is equal to one-thousandth of an inch), which allows the bags to be more easily reused and eventually recycled.

Styrofoam recycling at UW

Polystyrene foam (a.k.a Styrofoam) is a petroleum-based plastic. It’s typically tossed in the trash once it serves its purpose of insulating beverages and food or cushioning fragile items, but because Styrofoam does not decompose, a multitude of issues arise once it’s released into the environment. Examples include air and marine pollution, the release of toxic chemicals and the destruction of wildlife that ingests the plastic. So, how do you address a problem like polystyrene foam?
