Portland, Oregon Residential Single-Stream Recycling: What to Recycle and How

Understanding Portland’s Single-Stream Recycling: The Basics

Portland, Oregon, embraces single-stream recycling for residential properties, offering a convenient way to manage household waste. This system allows you to place all your accepted recyclable materials together into one blue roll cart, simplifying the process for residents. However, this convenience comes with a critical responsibility: proper sorting and preparation. Placing incorrect items, known as “wishcycling,” can contaminate an entire load, sending valuable resources to the landfill and undermining recycling efforts. Understanding and adhering to local guidelines is essential to ensure materials are viable for recycling and truly make a positive environmental impact.

Accepted Materials: What Goes IN Your Blue Roll Cart

Knowing precisely what Portland’s single-stream system accepts is key to successful recycling. For your blue roll cart, focus on these main categories of clean, empty, and dry items:

Paper and Cardboard

  • Corrugated Cardboard: Flattened moving boxes, shipping boxes, pizza boxes (remove significant food residue and liners).
  • Mixed Paper: Junk mail, newspapers, magazines, catalogs, phone books, paperbacks, cereal boxes (remove plastic liners), paper egg cartons, milk and juice cartons (rinse, flatten).
  • Shredded Paper: Place securely inside a paper bag before putting it in your cart to prevent small pieces from scattering and jamming machinery.

Plastics

  • Rigid Plastics Labeled #1, #2, and #5: Look for the chasing arrows symbol with the number inside. This typically includes plastic bottles (soda, water, milk jugs), plastic tubs (yogurt, butter, sour cream), and other rigid plastic containers. Rinse them thoroughly and ideally, leave caps on bottles larger than 2 inches.

Metal

  • Aluminum Cans: Soda cans, beer cans.
  • Steel/Tin Cans: Food cans (vegetables, soup, pet food). Rinse them clean. Empty aerosol cans are also accepted.
  • Aluminum Foil and Trays: Clean aluminum foil and disposable aluminum baking trays are accepted.

Glass

  • Glass Bottles and Jars: Clear, brown, and green glass food and beverage containers. Rinse them clean and remove lids (lids can often be recycled with metal if clean, or placed in trash). Labels do not need to be removed.

Common Contaminants: What Stays OUT of the Blue Cart

Just as important as knowing what to recycle is understanding what not to recycle in your blue cart. These items are common contaminants that can clog machinery, reduce the quality of recycled materials, or pose safety hazards.

Avoid these common mistakes:

  • “Wishcycling”: Placing items into the blue cart hoping they are recyclable, leading to contamination of the entire load. If in doubt, throw it out.
  • Plastic bags, plastic film (e.g., grocery bags, bubble wrap), or Styrofoam: These items are never accepted in the blue roll cart. They jam sorting machinery and cannot be processed efficiently.
  • Recycling containers with significant food residue or liquid: This contaminates other materials, attracts pests, and renders the items unrecyclable. Always rinse containers thoroughly.
  • Disposing of small, loose items: Items smaller than 2x2 inches (e.g., loose bottle caps not on bottles, very small plastic pieces) fall through sorting machinery and become waste.
  • Recycling tangling items: Hoses, wires, holiday lights, clothing, or other flexible items jam sorting equipment and create safety hazards for workers.
  • Not checking with specific haulers or official Metro resources: Recycling guidelines can change, and specific haulers may have slight variations. Always stay informed.

Preparing Your Recyclables: Clean, Empty, Dry, and Size Matters

Proper preparation is crucial for ensuring your recyclables can actually be processed. Think of these steps as giving your items the best chance at a new life:

  • Clean and Empty: All containers (bottles, jars, tubs, cans) must be rinsed thoroughly to remove food residue. Even a small amount of liquid or food can contaminate an entire bale of recyclables.
  • Dry: Allow items to air dry if possible, or give them a quick shake to remove excess water. Wet paper and cardboard can degrade and become unrecyclable.
  • Plastic Caps: For plastic bottles and jugs (e.g., milk jugs, detergent bottles), it’s generally recommended to leave the plastic caps on. If the cap is larger than 2 inches, it can often be left on as it will be sorted with the bottle. Smaller loose caps may fall through sorting equipment. Check with your specific hauler if unsure.
  • Shredded Paper: To prevent confetti-like paper from littering the sorting facility or falling through machinery, place shredded paper inside a paper bag (like a lunch bag or grocery bag) and then secure it before putting it in the blue cart.
  • Size Matters: Generally, items smaller than 2x2 inches are too small for sorting equipment and should be discarded. Flatten cardboard boxes to save space in your cart and aid in sorting.

Your Recycling Decision Checklist:

Before tossing an item into your blue cart, quickly run through these questions:

  • Is this item clean, empty, and dry before placing it in the cart?
  • Is it made of rigid plastic labeled #1, #2, or #5, paper/cardboard, metal, or glass?
  • Is it a plastic bag, plastic film, or Styrofoam? (If yes, it does not belong in the blue cart).
  • Is the item smaller than 2x2 inches (e.g., loose bottle caps not on bottles, very small plastic pieces) or a tangler (e.g., wires, hoses)?
  • If it’s shredded paper, is it securely contained within a paper bag?
  • Have I removed all non-recyclable components (e.g., pump dispensers, food residue, electronic parts) from accepted items?

Beyond the Blue Cart: Special Recycling & Disposal in Portland

Many items are recyclable but simply don’t belong in your single-stream blue cart due to their material type or processing requirements. Fortunately, Portland offers numerous alternatives:

  • Plastic Film & Bags: Look for designated drop-off bins at local grocery stores and retailers. These programs specifically collect clean, dry plastic film, grocery bags, bread bags, and bubble wrap.
  • Batteries: Household batteries (AA, AAA, C, D, 9V) and rechargeable batteries should be recycled at special collection sites. Many electronics stores and local transfer stations offer battery recycling. Car batteries are also accepted at specific facilities.
  • Hazardous Waste: Items like paint, chemicals, motor oil, and fluorescent bulbs are not for curbside recycling or trash. Portland Metro operates household hazardous waste facilities.
  • Electronics (E-Waste): Old TVs, computers, printers, and other electronics contain valuable materials and harmful chemicals. Oregon’s E-Cycles program provides free drop-off locations for residents.
  • Styrofoam: While not accepted in blue carts, some private facilities or occasional collection events may accept specific types of clean, dry block Styrofoam. Always verify current options.

Your Hauler & Official Resources: Staying Up-to-Date

Recycling guidelines can evolve, and your specific waste hauler may have additional or slightly varied instructions.

  • Identify Your Hauler: Your waste management provider is typically listed on your utility bill. Most residents are served by franchised haulers.
  • Official Resources: For the most accurate and current information, always consult:
    • Portland Metro: Their website (oregonmetro.gov) is the primary source for regional recycling and waste disposal guidelines, including specific search tools for “What To Do With” various items.
    • City of Portland Bureau of Planning and Sustainability: The city’s website (portland.gov/sustainability) also offers valuable local resources and connections to Metro’s recycling information.
