Material Item Depiction More Information
Aluminum can alumnium cans Aluminum soda cans are the most recycled material in the U.S. It does not deteriorate, meaning industries can make new aluminum products as long as we keep supplying them! The most popular use of recycled aluminum cans is more aluminum cans. It can be melted down and made into new products continuously. Besides more cans, it can able be turned into airplane parts, car parts, aluminum fences, baseball bats, and furniture! 
Aluminum foil aluminum foil Before you consider recycling your aluminum foil, you have to determine whether your local program accepts it. Check your community's website or go to Earth911's recycling locator. In most cases, if they'll take aluminum foil, they'll also accepted disposable pie tins and roasting pans. Recycling centers will often ask that you clean the foil before tossing it in with your other recyclables. If it's covered in grease or food, most recycling centers cannot accept it. If the aluminum foil is a part of a package - like yogurt containers, paper boxes, or drink containers - separate it, even if all pieces are recyclable. Once they're separated, make sure all the materials are clean, then crumble it into a ball to avoid it being blown out of your recycling bin. 
Tin/steel can tin can Most steel cans will have a paper label, which does not need to be removed before recycled. You should rinse your can out to remove any leftover food or residue. Make sure to completely remove the lid and insert it into the can, then pink the top so it closes. This will prevent wildlife from getting their heads stuck in the cans. Steel cans may be recycled indefinitely with no loss of quality. This means that nearly two-thirds of all steel manufactured comes from recycled steel!
White paper white paper Recycling centers that process recycled paper are set up to remove things like staples, paper clips, and the plastic windows on envelopes. Therefore, it's not necessary to remove them before recycling the paper! Besides easily recognizable paper products (e.g., writing paper or paper towels), more than 5,000 products can be made from recycled paper, including: masking tape, bandages, egg cartons, lamp shades, coffee filters, hospital gowns, animal bedding, and more than 4,993 other products!
Mixed paper stack of books Mixed paper is a very broad category that includes item such as note cards, greeting cards, wrapping paper, gift bags, unwanted mail, colored computer paper, newspaper, file folders, brochures, catalogs, paperboard/chipboard, softcover books, telephone books, journals and magazines, to name a few! Before recycling books, look for options or resale, reuse, or donate at places like public libraries. Paperboard is a single layer of cardboard, this includes items like cereal boxes!
Paper plates & cups paper cup Not likely though. Carefully check your cups, plates, and other paper containers to make sure that there's not a waxy lining or plastic film on the inside of the cup. If there is, unfortunately the item will have to be placed in the trash. If paper is lined with either of these, it ceases to be recyclable paper because the wax and plastic coating cannot be separated from the paper portion of the product. 
Cardboard cardboard boxes Break down all boxes to save space and remove any plastic packaging or other debris. Most pizza boxes are accepted.  Make sure they are empty and leave out the greasy ones. If the cardboard has a plastic or wax coating, landfill it.

Plastics

First things first, grab that piece of plastic you are about to recycle and look it over to find the Plastic Identification Code (PIC), the number inside the recycle symbol. If a plastic is labeled as compostable, it cannot be recycled in our region. 

plastic type examples

It is important to note that the OSU Recycles program does not accept plastics for recycling other than #1-2 bottles. As of July, 2017, the City of Stillwater takes #1, #2, and #5 bottles, jugs and tubs in their single-stream curbside recycling program and at the Convenience Collection Center on Perkins Rd.  The ResLife Recycles program also accepts #1, #2, and #5 bottles, jugs and tubs.

  • #1 PET or PETE (Polyethylene Terephthalate)
    This is one of the most commonly used plastics. It’s lightweight, strong, typically transparent and is often used in food packaging and fabrics (polyester). 
     
    Examples: Beverage bottles, Food bottles/jars (salad dressing, peanut butter, honey, etc.) and polyester clothing or rope. 
  • #2 HDPE (High Density Polyethylene)
    Collectively, Polyethylene is the most common plastics in the world, but it’s classified into three types: High-Density, Low-Density and Linear Low-Density. High-Density Polyethylene is strong and resistant to moisture and chemicals, which makes it ideal for cartons, containers, pipes and other building materials. 
     
    Examples: Milk cartons, detergent bottles, cereal box liners, toys, buckets, park benches and rigid pipes.
  • #3 PVC (Polyvinyl Chloride)
    This hard and rigid plastic is resistant to chemicals and weathering, making it desired for building and construction applications; while the fact that it doesn’t conduct electricity makes it common for high-tech applications, such as wires and cable. It’s also widely used in medical applications because it’s impermeable to germs, is easily disinfected and provides single-use applications that reduce infections in healthcare. On the flip side, we must note that PVC is the most dangerous plastic to human health, known to leach dangerous toxins throughout its entire lifecycle (eg: lead, dioxins, vinyl chloride).  
     
    Examples: Plumbing pipes, credit cards, human and pet toys, rain gutters, teething rings, IV fluid bags and medical tubing and oxygen masks.
  • #4 LDPE (Low-Density Polyethylene)
    A softer, clearer, and more flexible version of HDPE. It’s often used as a liner inside beverage cartons, and in corrosion-resistant work surfaces and other products. 
     
    Examples: Plastic/cling wrap, sandwich and bread bags, bubble wrap, garbage bags, grocery bags and beverage cups.
  • #5 PP (Polypropylene)
    This is one of the most durable types of plastic. It is more heat resistant than some others, which makes it ideal for such things as food packaging and food storage that’s made to hold hot items or be heated itself. It’s flexible enough to allow for mild bending, but it retains its shape and strength for a long time.
     
    Examples: Straws, bottle caps, prescription bottles, hot food containers, packaging tape, disposable diapers and DVD/CD boxes.
  • #6 PS (Polystyrene)
    Better known as Styrofoam, this rigid plastic is low-cost and insulates very well, which has made it a staple in the food, packaging and construction industries. Like PVC, polystyrene is considered to be a dangerous plastic. It can easily leach harmful toxins such as styrene (a neurotoxin), which can easily then be absorbed by food and thus ingested by humans.
     
    Examples: Cups, takeout food containers, shipping and product packaging, egg cartons, cutlery and building insulation.
  • #7 Other
    This category is a catch-all for other types of plastic that don’t belong in any of the other six categories or are combinations of multiple types. We include it because you might occasionally come across the #7 recycling code, so it’s important to know what it means. The most important thing here is that these plastics aren’t typically recyclable. 
     
    Examples: Eyeglasses, baby and sports bottles, electronics, CD/DVDs, lighting fixtures and clear plastic cutlery.

Recycling FAQs

Here are some commonly asked questions regarding recycling at OSU. If you don't see your question listed below, please feel free to contact us at recycle@okstate.edu

  • Someone told me the recycling just goes to the landfill, is that true?
    No! The materials recycled here on campus are picked up by Republic Services and taken to Cedar Creek Farms, a local recycling facility.
     
    Keep in mind, if you see a custodian placing a bag of recyclables in a cart with bags of trash, that doesn’t mean it is being discarded.  At most campus buildings, the recycle dumpster is adjacent to the trash dumpster, so the custodian is simply using the same cart as a conveyance and will place bags in the appropriate container outdoors. All cardboard, paper, plastic bottles, and aluminum cans collected in the program do get recycled!
  • How do I arrange for a special event or office clean-up?
    Please contact the OSU Recycling Department in order to arrange for a special event or office clean up by email or by calling 405-744-4354. You will need to generate a work order, but there is no cost for this service.
  • Where do custodians take it?
    Custodians place tied-off bags of paper, tied-off bags of bottles/cans, and flattened cardboard outside into green recycle dumpsters when they take trash outside to beige refuse dumpsters.
  • Why recycle?
    After we’ve reduced the amount of waste we generate and reuse everything as much as possible, the next step is to recycle. Recycling is important because it helps decrease the need for virgin materials, which are often costly to extract in terms of the effect on the environment, on local communities, and on our wallets.
