Bottle caps or lids
Cartons (ie: milk, juice, ice tea, lemonade)
Carbon Paper
Cellophane (ie: candy wrappers, snack food bags)
Coffee Cups
Plastic bags (clean, dry bags can be recycled at many grocery stores)
Plastic tubs (ie: yogurt, cottage cheese)
Styrofoam

The only kiosk that collects athletic shoes is located in the Recycling Center in the Cohon University Center.
E-waste: E-Media, Small Electronics, and Film
CMU works with a vendor to recycle small non-regulated media, such as floppy disks, zip disks, cassette tapes, VHS tapes, CDs, and DVDs, cell phones, MP3 players, film negatives, microfiche, and more.

Wood pallets
We currently have a diversion source for 48" by 48" sized pallets. These need to be in good condition.
To request items collected for reuse, please submit a State that you are "requesting a warehouse pick up of standard size (48" x 48") pallets that are in good, reusable condition". When the work order is processed, please forward it to urs-penn@andrew.cmu.edu. Pallet pickup should not incur a fee to your department.
We can not accept oversized, broken, or damaged pallets. We also do not accept other wood waste. These items currently get removed as landfill.
If you frequently have waste waste, please contact GreenPractices@andrew.cmu.edu as we are researching recycling opportunities and it is helpful to know how much of this waste type is generated on campus.
Off-Campus Recycling
