Hard-to-Recycle Materials

Cell Phone Recycling

Cell Phone Recycling

As cell phones are constantly being upgraded, the outdated phones need to be disposed of in a responsible and environmentally friendly manner.听This service is ONLY for waste generated on campus.

CU Recycling has formed a partnership with听听to reuse and recycle old cell phones.

To recycle your old cell phone on the CU campus, the main options are:

  • Drop Off Location: Environmental Center,听University Memorial Center- UMC 355.
  • Or check out the听.

Types of materials accepted

  • Any cell phone (working or broken).
  • Cell phone chargers.
  • Cell phone batteries.
  • iPods, MP3 players, portable CD players.
  • Tablets (working or broken).
  • Bluetooth devices (small).
  • Electronic accessories (small).

Electronics Recycling (E-Waste)

Did you know electronic waste, also known as e-waste, is the fastest-growing component of waste worldwide? In the United States alone, we throw out approximately 130,000 computers daily and 100 million cell phones annually. Please recycle aged electronics, cell phones or appliances that cannot be re-used.

Recycling E-Waste On Campus听

When recycling electronics, it is always good practice to ensure the equipment is being recycled responsibly.听Property Services听ensures all university-owned electronics are disposed of responsibly, following the highest industry standards for sustainability. In fact, 100 percent of the university's surplus electronics are diverted from landfill by staff.

Recycling E-Waste Off Campus听

听for electronic waste contains useful information for your off-campus recycling needs. The Eco-Cycle facility CHaRM (Center for Hard-to-Recycle Materials) in 麻豆影院 works with Electronics Recyclers International, who are certified to assure electronic scrap is safely processed.听听for specifics on accepted materials and fees.

Best Buy also offers electronics and appliance听recycling at their store locations with many FREE options to recycle materials. 听听to find out what is acceptable at a store near you!

Clothing

There are two big ways to join the sustainable Herd in reusing:

  • Before you head to the store to buy something new, check thrift shops and online exchange sites.
  • Instead of throwing your old items out, donate them or sell them secondhand.

These two actions will save the Earth while saving you money! Lucky for you, 麻豆影院 has plenty of resources to help you reuse. Thrift stores aren't all clothes and furniture- you can reuse almost anything around here!

Less clothing in landfills

  • .
  • Most clothes are made from听, which take hundreds of years to decompose in landfills.

Fewer resources used and wasted

  • Making clothes takes a lot of water. It is estimated that听听in growing the cotton used and in processing.
  • Thrifting will help keep these resources from going to waste and help stop the drive of companies to be constantly producing more.

Helps to reduce chemical pollution

  • Most cotton used to make clothing is genetically modified which means growing it is highly pesticide-intensive. Pesticides can lead to听.
  • Textile manufacturing processes usually involve harmful dies and crude oil by-products. These听听which contaminates surface and groundwater.

Compostable Paper

Due to changing guidelines the following items are not currently being accepted for composting

  • Plastic lined paper.
  • Wax coated paper is okay.
  • #7 PLA coated paper.
Paper Towels/Napkins/Wood

Due to changing guidelines the following items are not currently being accepted for composting

  • Paper towels, napkins, or tissues.
  • Do not put them in the recycling bin. The paper quality is too low to be recycled and there is often food residue on them.
  • Cloth, plastic coated, or other types of rags.
  • Wood.
Compostable Plastics

Due to changing guidelines the following items are not currently being accepted for composting

  • Certified compostable plastics, even if they have the following identifiers:
    • BPI Certified
    • #7 PLA on the plastic
    • The word "Compostable"
Plastic Bags
  • Plastic bags are a hard-to-recycle听item.
  • Bags need to be kept separate, clean and dry.
  • Take bags to a special place for recycling: CHaRM, Grocery Stores, Home Depot.
  • Do not put bags in your normal recycling bin.
  • Bags get caught in recycling sorting equipment and cause machines to break/bind up.
  • Avoid plastic bags and bring reusable bags wherever you go.
Paper Cups
  • Most paper cups have a plastic lining on the inside.
  • This plastic lining cannot be separated when recycling paper back to pulp.
  • Plastic linings create enough contamination to ruin a batch of paper recycling.
  • Do not put any paper cups into the recycling bin.
  • If the cup says compostable, it can go into the compost bin.
Wrappers and Packets
  • Do not recycle film plastics or thin plastic films in your normal recycling bin.
  • Wrappers and packets cannot be easily seperated with sorting equipment.
  • Wrappers and packets often do not have an end market to turn into a new product.
  • Some companies, like听, have options if wrappers are kept separate and shipped directly to them.
Frozen Food Boxes
  • Frozen food boxes have a "chemical wet strength" barrier that soaks through paper fibers.
  • "Wet strength" is used to prevent freezer burn or leakage in transport.
  • This chemical also contaminates the paper recycling process when mixed with normal paper fibers.
  • Some companies make recyclable frozen food boxes, but most frozen boxes are not recyclable so keep them out of the recycling.
Styrofoam
  • Styrofoam is not acceptable in your normal recycling bin.
  • #6PS (PolyStyrene) block foam is a hard-to-recycle item and has to be kept separate, clean and dry to be recycled at a special location (CHaRM in 麻豆影院).
  • Styrofoam serving ware (cups, plates, to-go boxes, utensils, etc.) cannot be recycled and must go to the landfill.
  • Styrofoam packing peanuts are not recyclable.听Please put them in a bag so they don't fly away, then put them in the landfill bin.
Neon and Goldenrod Paper
  • Neon, Goldenrod, and any heavily dyed paper is not recyclable.
  • The paper fibers have too much dye to be removed without a lot of chemicals, if at all.
  • Like with a red sock in a load of white laundry, neon and goldenrod paper will dye the rest of the recycled paper and ruin the batch.
Ceramics
  • Ceramics contaminate the glass recycling process.
  • Ceramics have a different melting temperature than glass.
  • If mixed with glass during recycling, ceramics cause impurities in the glass, causing it to break.
  • Donate any dishware, mugs or reusable dishware to your local thrift store.
  • Ceramics cannot be recycled themselves and must go to the landfill.
Mirrors, Lightbulbs and Glass Panes
  • These glass types all听contaminate the glass recycling process.
  • They have a different melting temperature than glass.
  • If mixed with glass, these items will cause impurities in the glass, causing it to break.
  • Donate any reusable mirrors听to your local thrift store.
  • Mirrors cannot be recycled themselves and must be put in the landfill.
  • Light Bulbs can be听听or听must be put in the landfill.
  • Glass Panes听can be听听or听must be put in the landfill.
Lab Glass and Pyrex
  • Lab glass and Pyrex have different melting temperatures than glass in drinking bottles.
  • Any amount of these items will contaminate the recycling process for glass drinking bottles.
  • No markets exist to use recycled lab glass or Pyrex, so they must go to the landfill.
