Denver Curbside Recycling: Schedule, Accepted Items & Best Practices

Denver’s commitment to sustainability starts at your curb. Navigating residential recycling schedules and understanding accepted materials can sometimes feel complex, but it’s crucial for effective waste reduction. This guide provides clear, actionable information for Denver residents to ensure their recycling efforts are successful, helping keep our city clean and green.

Find Your Specific Denver Recycling Pickup Schedule

Denver provides a convenient online tool to pinpoint your exact bi-weekly recycling collection day. This service ensures you never miss a pickup and can plan accordingly.

To find your schedule:

  1. Visit the Official Denver Waste Services Schedule Website: Navigate to the Denver Solid Waste Management’s dedicated online portal.
  2. Enter Your Denver Address: Input your full residential address into the search bar.
  3. View Your Personalized Calendar: The tool will display your specific recycling collection dates, clearly indicating which weeks your blue cart will be serviced. Remember, collections are bi-weekly.
  4. Consider a Printed Calendar: Many residents also receive an annual waste services calendar by mail, which includes both trash and recycling dates. Keep this handy as a physical backup.

It is essential to verify your specific address’s schedule, as collection routes can vary even within the same neighborhood.

Accepted Materials: What Goes in Your Blue Denver Recycling Cart?

Understanding what is accepted in Denver’s blue curbside recycling cart is paramount to preventing contamination. Only place items explicitly listed below.

Paper and Cardboard

  • Corrugated Cardboard: Flattened boxes from shipping, moving, etc. (must be clean and dry).
  • Paperboard: Cereal boxes, tissue boxes, paper towel rolls (flattened, no food residue).
  • Mixed Paper: Junk mail, magazines, newspapers, catalogs, phone books, office paper, envelopes (no shredded paper).
  • Paper Cartons: Juice, milk, soup, broth cartons (rinsed, caps left on or removed).

Plastics

  • Plastic Bottles, Jugs, and Tubs: These are generally identifiable by a #1 (PET) or #2 (HDPE) symbol. Examples include soda bottles, milk jugs, detergent bottles, yogurt containers, butter tubs, and some deli containers (rinsed, caps on or off).
  • Please note: Denver primarily accepts plastics #1 and #2 in bottle, jug, or tub form. Other plastic types or forms are generally not accepted.

Metals

  • Aluminum Cans: Soda, beer, and other beverage cans (rinsed).
  • Steel/Tin Cans: Food cans like soup, vegetable, or pet food cans (rinsed, labels can remain).
  • Empty Aluminum Foil/Trays: Clean, balled up foil or clean aluminum food trays.

All accepted materials should be clean, dry, and placed loosely into the blue cart.

Contaminants: What NEVER Goes in Your Denver Recycling Cart?

Placing non-recyclable items, often called “wishcycling,” contaminates the recycling stream, making it harder and more expensive to process legitimate recyclables. Entire loads can be rejected due to high contamination.

Common contaminants to keep out:

  • Plastic Bags & Plastic Film: Grocery bags, sandwich bags, plastic film, bubble wrap. These jam sorting machinery. Take them to designated store drop-off locations.
  • Styrofoam: Cups, packing peanuts, takeout containers. These are not recyclable in Denver’s curbside program.
  • Food Waste: Any food scraps, greasy pizza boxes, or containers with significant food residue. These attract pests and contaminate paper/cardboard.
  • Electronics (E-waste): TVs, computers, cell phones, batteries. These require special hazardous waste disposal.
  • Glass (Broken or Unbroken): Important change: Denver’s curbside program generally does not accept glass. Residents must take glass to designated drop-off centers. Verify current city guidelines as programs can evolve.
  • Clothing & Textiles: Donate usable clothing; worn textiles can often be recycled at specialized centers.
  • Hazardous Waste: Paint, chemicals, motor oil, medical waste. These need specialized disposal.
  • Garden Hoses, Wires, Chains: These “tanglers” cause significant issues for sorting equipment.
  • Ceramics, Dishes, Drinking Glasses: These are not the same type of glass as bottles/jars and melt at different temperatures.
  • Diapers: Never place soiled diapers in recycling.

When in doubt, throw it out – or better yet, verify its recyclability with official Denver resources.

Preparing Your Recyclables for Denver Pickup

Proper preparation ensures your efforts lead to actual recycling. A few simple steps make a big difference:

  • Rinse Containers: Quickly rinse all plastic, metal, and carton containers to remove food residue. This prevents odors and contamination.
  • Dry Items: Ensure items are relatively dry before placing them in the cart. Wet paper and cardboard can mold and become unrecyclable.
  • Flatten Cardboard: Break down and flatten all cardboard boxes to save space in your cart and facilitate collection.
  • Lids & Caps: Small plastic lids and caps can usually be left on plastic bottles and jugs. Metal lids from jars should be removed and can be recycled if they are steel/tin.
  • Loose in the Cart: Always place items loosely in your blue cart. Never bag recyclables, even in clear bags, as they will be treated as trash.

Understanding Your Denver Recycling Cart & Collection Day

Your blue cart is designed for convenience and efficiency. Knowing the rules for its use helps ensure smooth service.

  • Bi-Weekly Collection: Remember that recycling is collected every other week. Confirm your designated week using the online schedule tool.
  • Placement: Place your cart at the curb with wheels against the curb, handle facing your house. Ensure at least three feet of clearance around the cart from obstacles like parked cars, mailboxes, or other waste bins.
  • Time: Carts must be at the curb by 7:00 AM on your collection day, but no earlier than 5:00 PM the day before.
  • Lid Closed: The lid must be completely closed. Overfilled carts with open lids can lead to spilled materials or missed collection.
  • Weight Limit: While there’s no strict household weight limit listed, ensure the cart isn’t excessively heavy, preventing the automated arm from lifting it.
  • Missed Collection: If your recycling was out on time and properly prepared but missed, contact Denver Solid Waste Management or 311 within 24 hours of your scheduled pickup day.
  • Damaged or Stolen Cart: Report damaged or stolen carts to the city to arrange for repair or replacement.

Decision Checklist for Your Blue Cart

  • Have I entered my address into Denver’s Waste Services Schedule tool to confirm my exact bi-weekly pickup day and week?
  • Are ALL items in my blue cart on Denver’s official ‘Accepted Materials’ list and free from unapproved items?
  • Are all plastic, glass, and metal containers thoroughly rinsed and free of significant food residue?
  • Is all cardboard flattened and dry, and are paper products clean and free of food grease?
  • Is the cart placed at the curb by 7 AM on collection day, with at least three feet of clearance from obstacles and the lid closed?
  • Have I removed all plastic bags, even if they contain recyclables, from the cart?

Common Recycling Mistakes to Avoid in Denver

  • Wishcycling: Placing items in the recycling cart hoping they are recyclable without verifying, leading to contamination and potential rejection of entire loads.
  • Not cleaning containers: Leaving significant food residue in plastic, glass, or metal containers, which contaminates other materials, attracts pests, and can lead to the entire cart being rejected.
  • Recycling items in plastic bags: Bagging recyclables or placing grocery bags directly into the cart; plastic bags tangle machinery and are not accepted in Denver’s curbside program.
  • Including unaccepted plastics: Attempting to recycle plastics other than #1 (PET) and #2 (HDPE) bottles, jugs, and tubs, such as plastic clam-shells, Styrofoam, or plastic film.
  • Overfilling or improperly placing carts: Leaving cart lids open, exceeding weight limits, or blocking cart access (e.g., by parked cars or trash cans), leading to missed pickups or spillage.
