5th Saturday

Less than 24-hour old sushi (receipt to prove it). The fish flew may have flown in from far away

Interestingly, a cabbage was split half and half between the landfill and the compost receptacles.

Andrew finds durable tubes in the landfill. These are good for protecting posters during transport.

Collection boxes for the Skin Deep Clothing Exchange and for reusable dining hall cups. Would these items have otherwise ended up in our waste streams?

A new idea occurred to us this weekend, noticing cross-contamination between landfill and recycling receptacles in Cassat. The receptacles here are the exact same shape, and looking overhead, they appear the same—both are lined with a black bag. Only when viewed laterally can you see the difference between these bins—one is grey, the other is blue. We now hypothesize that some cross-contamination may be due to simple placement errors, i.e. the student correctly identifies his or her item as recyclable, but accidentally places it in the wrong receptacle. A strategy for decreasing contamination rates may then be to not only color bins differently, but to make sure that they are shaped differently as well. These properties would overlap with the relative sizing of the bins: ideally, the compost and recycle bins are sized much larger than the landfill bin, to reinforce that most waste is compostable or recyclable.
