Help the ASCP divert compost and recycling from entering the landfill by using this sorting guide!


In a Fall 2018 waste audit, the ASCP discovered that, on average, 53% of the material in our surveyed landfill bins is compostable. We also know that plastics, which often end up in our campus landfill bins, never really decompose, but just fracture into smaller and smaller pieces to be ingested by wildlife and, eventually, humans.


Note: The Auraria campus is serviced by Alpine Waste. All waste haulers and processors accept different materials and offer different collection guidelines. This guide reflects Alpine’s guidelines and may differ from the waste hauler servicing your house/apartment.



Where does it go? Compost is organic matter that can be decomposed to create fertile soil. Auraria’s compost decomposes at a large industrial-scale site by the airport and is sold to farmers.


How to? You cannot compost any plastic or items with chemical residue on them. Items you should compost include:

  • ALL food items, including

    • Produce (remove the sticker!)

    • cooked and raw meat & dairy products

    • bones, fish, eggshells

  • Soiled wooden and paper items:

    • Napkins and greasy paper bags

    • Greasy pizza boxes (if clean, recycle!)

    • Chopsticks, toothpicks, popsicle sticks, wooden stir sticks

  • Food packaging and soiled paper products that are made of paper fibers, plants, corn, and SOME #7 PLA (MUST say PLA)

    • Compostable to-go containers and utensils

    • Compostable cups (look for “BPI Certified”)

    • sandwich/burger etc. wrappers

    • sugar packets

  • Tea bags and coffee filters

  • Plants and flowers



Where does it go? Recycled items are reconstructed into new bottles, cans or paper. Auraria Campus supports single stream recycling, meaning paper, plastic, metal and glass are all recycled in one bin.


How to? You cannot recycle Styrofoam, shrink wrap, or anything smaller than a business card (ie: creamer cups). Items must be CLEAN or our waste hauler will send them to the landfill. Be sure to wipe off leftover food residue with a napkin and throw the soiled napkin in the compost bin. Items you should recycle include:

  • All types of paper, including:

    • printer paper
      Note: shredded paper needs to be composted or recycled with special instructions. See below. 

    • newspaper

    • magazine

    • Cardboard - must be flattened

  • Rigid plastic containers

  • Plastic jugs and bottles marked #1 through #6
    Note: include the plastic bottle cap on top, it can be recycled too!
    TIP: wipe out the containers with a paper napkin and compost the napkin!

  • Plastic lined paper cups, including:

    • soda cups

    • coffee cups
      Note: plastic cup lids are not recyclable

  • Aluminum cans - dont crush them!

  • Cardboard cartons - milk, juice, etc.

  • Glass bottles - remove the cap



Where does it go? Landfill waste is piled into cells, layered with dirt, and left to sit—largely unchanged—forever. Over time, landfills produce methane, a potent greenhouse gas.  


How to? Do your part to help keep compostable and recyclable items out of landfills. Items that should be put in the landfill bin:

  • Single-use plastics including:

    • plastic utensils, plates, stir sticks, straws

    • condiment packets

    • creamer containers

    • plastic wrappers (chips, candy, bars)

    • plastic straws

  • Plastic clamshell containers

  • Styrofoam cups and containers

  • Anything seriously contaminated with food residue

  • Anything smaller than a business card

  • Shrink-wrap

  • Plastic bags (but you CAN recycle them at grocery stores!)

Hard to Recycle Items

Happy to help you dispose of your hard to recycle materials through our four programs by visiting the H2R page!


"What About This?"

Here are some helpful tips on tricky or hard to recycle items:



  • Thin plastic soda and coffee lids are NOT recyclable through Alpine, even though they have a recycle symbol and #.

  • Bottle/Jar Lids: If a lid is the same material as the bottle (ie: plastic on plastic), keep it on. If it is different (metal lid, glass bottle), remove the lid.



  • Large, dense packing Styrofoam (found around new appliances) CAN be recycled in our blue bins (clamshells cannot). This is a unique service offered by Alpine.


Many items CAN be recycled if they are batched together at special collection sites:



  • E-Waste can be dropped off in e-Waste bins located in front of the Tivoli Station Bookstore and in the northeast corner of the Arts Building. Acceptable items include:

    • batteries, power cords, small electronics (1.5” thick or less), laptops, tablets, and phones

    • The ASCP hosts two e-waste recycling events throughout the year for larger electronic items. Text ASCP to 22828 to sign up for the ASCP Newsletter, where events will be announced.



  • Plastic bags CAN be recycled in batches at many grocery store collection sites, including most Albertson's, King Soopers, Safeway, Whole Foods, Wal-Mart and Target!



  • Shredded paper will clog the machines at Alpine’s sorting facility. However, you can either compost it, recycle it by putting it in a closed paper bag or cereal box, or take it to Office Max or Shred Nations for a small fee. See Denver's Trash and Recycling Directory for more info. 



  • The Denver Trash and Recycling Directory allows you to type in the name of the material you would like to recycle and learn where to recycle or compost just about anything!
