General Recycling

“Commingle,” or single stream recycling allows you to recycle materials without taking the time or effort to sort them. With commingled recycling service, all of your approved recyclables can be tossed into one easy-to-use recycle bin. We provide adequate recycling bins to ensure that there is always a convenient choice between trash and recycling.

Are you wondering how your recyclables are sorted? Check out Waste Management's video on what happens to your recycling.

Plastics come in many varieties and utilize a numbering system from 1-7. Plastics accepted in typical recycling programs are #1, #2 and #5. #1 and #2 are clear beverage containers and #5 are typically yogurt and cottage cheese containers. At NIU, we recycle all plastics, numbers 1-7. Any plastic with an RID number also is recyclable through Waste Management with the exception of polystyrene (Styrofoam). Polystyrene, plastic bags, and most plastic packaging are not recyclable. Hard plastic caps are also not recyclable.


Make sure paper recyclables are dry, wrapped in twine or in a paper bag, and contain no plastic or other materials before placing them in a recycle bin. Acceptable recycle bin paper includes newspapers, printer paper, junk mail, magazines, notebooks, cardboard and phone books. There are some papers that will not be accepted, such as food contaminated paper, wax paper, wax milk cartons, carbon paper, and etc. Tissues and used paper towels are not recyclable. At NIU, there are some recycling bins specifically for paper, but paper and cardboard can also be mixed in our single stream recycling system.


All colored glass is recyclable: brown, green, clear, etc. Pyrex glass, window glass, and ceramics are not recyclable in our program. Broken glass should NOT be placed in the recycling bin for safety reasons. Most glass that is recycled at curbside in your recycle bin is bottle glass. Other types may require a local recycle hauler to come to your home and pick it up.


The vast majority of aluminum recycling consists of aluminum beverage containers. Make sure they are empty and clean. Other types of aluminum are acceptable if they have been imprinted with a recycling symbol and are small enough to fit in the recycling bin.


Other materials such as motor oil, batteries, tires, and toxic items, must be recycled elsewhere. It is best to find a reputable hauler who can be trusted to recycle those materials properly. See our Community Resources page for further information on ways to recycle various materials.
