In general, a typical Colby recycling station in office and residence hall buildings is comprised of the following bins:

  • Mixed Recycling[Built into stations or loose bins that tend to be blue with a recycling logo.] Mixed recycling is one bin that accepts EVERYTHING recyclable. All papers (including all office paper, envelopes, and paperboard such as cereal boxes, beverage boxes, pizza boxes), bottles, plastics 1-7, cans, and other metal and glass. Please note, containers should be clean of food or drink residue. 
    Cardboard: Corrugate cardboard can also be put in mixed recycling, but if it’s too large it should be broken down and left next to any recycling station where it will be recycled appropriately. Mixed recycling is handled by Waste Management (
  • Composting (Spa Only)This bin is for food waste and compostable materials. Food waste is any and all food including meat products and bones. Compostable materials include spa plasticware, napkins and wax paper, paper cups and compostable lids, tea bags, and anything else that says compostable on it. Our composting goes to Exeter Agri-Energy, in Exeter, ME. (
  • Landfill: [Built into stations or a loose grey bin.] Any item that can’t be recycled, like food waste & wrappers, plastic bags, wax paper, styrofoam etc. can be placed in the trash container. All trash is brought by Waste Management ( to a landfill gas methane recapture facility in Norridgewock, Maine.

Other Recyclable Products:

  • Compact Fluorescent Lamps (CFL) – Submit a work order to PPD to have your burnt-out CFL picked up and disposed of properly.
  • Printer Cartridges – Have your own personal work printer? If so, the printer cartridges can be placed in the recycling room in the basement of Eustis and be properly recycled. Colby vendor PPCI recycles all campus printer cartridges.
  • Batteries – Bring used work batteries – alkaline or other to Miller 09 or the PPD building for them to be properly recycled.
  • Cell Phones – Bring any old cell phones to Miller 09 and they will be recycled at a local recycling center.
  • Office Goods and Clothing – The Sustainability Office and EnviroCo support two Freecycle Events during the year, an opportunity to donate lightly used items that others may want/need. If you have any clothing or folders, pens, pencils, staplers, staples, or other that you don’t need, drop them off at the Sustainability Office in Miller 09, and they will be a part of the campus Freecycle Event. Any items that aren’t claimed will be donated to the Mid-Maine Homeless Shelter.
  • Work Computers / Laptops – ITS (Lovejoy 120) and the Sustainability Office (Miller 09) are the two computer recycling centers on campus. All work computers’ hard drives are erased and then donated to local schools or non-profits or recycled locally.
  • Athletic Shoes / Dress shoes – Any shoes, no matter their shape, are accepted at Miller 09, or in the vestibule of the Athletic Center. Old, torn shoes, will be grinded up and used for rubber surfaces. Nicer, lightly used shoes will be donated to the Mid-Maine Homeless Shelter.
