Seattle Residential Curbside Recycling: What to Put in Your Blue Bin

Introduction: Why Seattle’s Curbside Rules Matter

Recycling in Seattle isn’t just about tossing items into a bin; it’s about following specific guidelines to ensure what you recycle can actually be processed and reused. Adhering to Seattle Public Utilities (SPU) rules is crucial. When non-recyclable items or contaminants (like food residue) end up in the blue bin, they can spoil entire batches of valuable materials, increase processing costs, and even send otherwise recyclable goods to the landfill. This guide aims to clarify Seattle’s residential curbside recycling program, helping you contribute effectively to the city’s waste reduction and resource recovery efforts.

Accepted Materials: Your Curbside Recycling Basics

Seattle’s curbside program focuses on common household items that can be efficiently sorted and processed. Always ensure items are clean, empty, and dry before placing them in your blue bin.

Paper & Cardboard

  • Accepted: Flattened cardboard boxes (e.g., shipping, cereal, tissue boxes), paper bags, newspapers, magazines, catalogs, junk mail, office paper, phone books, paper egg cartons, paper tubes (from toilet paper/paper towels).
  • Note: Shredded paper is accepted only if placed in a paper bag (not plastic) and rolled shut at the top.

Plastics

  • Accepted: Rigid plastic containers with symbols #1, #2, or #5. This typically includes plastic bottles (like milk jugs, detergent bottles), tubs (like yogurt, butter, sour cream containers), and jugs. They must be empty and rinsed.
  • Important: Lids smaller than 3 inches in diameter should be discarded in the trash unless attached to the container, as they often fall through sorting machinery.

Metal & Glass

  • Accepted: Clean aluminum cans, steel/tin cans (e.g., soup, vegetable cans), aluminum foil (clean, rolled into a ball 2 inches or larger), and glass bottles and jars of any color (empty and rinsed).
  • Note: Keep glass bottles and jars separate from ceramics, which are not recyclable curbside.

Prohibited Materials: What Never Goes in the Blue Bin

Understanding what not to put in your recycling bin is just as important as knowing what to include. These items are common contaminants that can damage equipment, endanger workers, or render entire loads unrecyclable.

  • Plastic Bags & Plastic Film: Absolutely no plastic bags, plastic wrap, or plastic film of any kind (e.g., grocery bags, dry cleaning bags, produce bags, bubble wrap). They tangle in sorting machinery. Look for specific drop-off locations for plastic film.
  • Styrofoam: All forms of Styrofoam (e.g., packing peanuts, cups, take-out containers) are not accepted curbside.
  • Food Waste & Liquids: Food-soiled items or containers with significant food/liquid residue. Always rinse containers thoroughly.
  • Small Items: Anything smaller than 2x2 inches (e.g., bottle caps not attached to containers, loose shredded paper, plastic cutlery) often falls through sorting screens and becomes trash.
  • Ceramics & Dishes: Plates, mugs, vases, drinking glasses, window glass, mirrors, Pyrex. These have different melting points than recyclable glass bottles and jars.
  • Electronics & Batteries: Never in the blue bin. These require special disposal due to hazardous materials.
  • Hazardous Waste: Paint, chemicals, motor oil, fluorescent bulbs. These need specific hazardous waste drop-off facilities.
  • Textiles & Clothing: Not accepted curbside. Look for donation centers or textile recycling programs.
  • Garden Hoses, Wires, Chains: These ‘tanglers’ can jam machinery.

Preparation Protocol: Clean, Dry, and Ready

Proper preparation ensures that your recyclables can actually be recycled. A little effort goes a long way in preventing contamination.

  • Rinse Containers: Quickly rinse out food and liquid residue from plastic bottles, tubs, jugs, glass jars, and metal cans. They don’t need to be spotless, just free of significant debris.
  • Empty: Ensure containers are completely empty. Liquids can contaminate paper products.
  • Dry: While rinsing is important, avoid placing dripping wet items in the bin, especially paper and cardboard.
  • Flatten Cardboard: Break down and flatten cardboard boxes to save space in your bin and on the collection truck.
  • Attach Lids: If a plastic lid is larger than 3 inches in diameter, it can usually be recycled loose. If smaller, reattach it to the empty plastic bottle/jug so it doesn’t get lost in sorting.
  • Keep It Loose: Place all accepted recyclables loose in your blue bin. Do not bag them, except for shredded paper in a paper bag as noted above.

Beyond the Bin: Special Items & Drop-Off Options

For items not accepted in your curbside bin, Seattle offers various alternative disposal and recycling options.

  • Plastic Film: Many local grocery stores (e.g., QFC, Fred Meyer, PCC) have collection bins for clean, dry plastic film (e.g., grocery bags, bread bags, produce bags, stretch wrap).
  • Electronics (E-Waste): King County offers several drop-off locations for electronics. Search for ‘King County E-cycle Washington’ for facilities.
  • Batteries: Rechargeable batteries (e.g., from laptops, power tools) can be dropped off at participating retail locations (e.g., electronics stores, hardware stores) or King County Household Hazardous Waste facilities. Alkaline batteries (AA, AAA, C, D) can be safely disposed of in the trash, though some facilities may accept them for recycling.
  • Household Hazardous Waste (HHW): Items like paint, pesticides, automotive fluids, and fluorescent bulbs should be taken to King County Household Hazardous Waste drop-off sites. Check their website for locations and accepted materials.
  • Large Appliances & Scrap Metal: Contact your waste hauler for special pickup options or look for local scrap metal recyclers.

Navigating Your Collection Schedule & Bins

Most residential properties in Seattle receive weekly recycling collection. Seattle Public Utilities (SPU) typically provides a blue recycling cart.

  • Collection Day: Your specific collection day depends on your address. You can look up your schedule on the SPU website.
  • Bin Placement: Place your blue cart at the curb or alley by 7:00 AM on your collection day, ensuring it’s at least three feet away from other carts, parked cars, or obstacles. The lid should be fully closed.
  • Bin Size: SPU offers different recycling cart sizes. If your household’s needs change, you may be able to request a different size by contacting SPU.

Official Resources & Troubleshooting

For the most current and specific information, Seattle Public Utilities is your primary resource.

  • SPU Website: Visit seattle.gov/utilities/services/recycling for comprehensive guidelines, program updates, and resources.
  • ‘What Do I Do With…?’ Tool: SPU provides an online tool where you can search for specific items to determine their proper disposal method in Seattle. This is an excellent first step if you’re unsure about an item.
  • Missed Collections: If your recycling was not picked up as scheduled, contact SPU or your waste hauler directly to report the issue.
  • Contact SPU: For questions or assistance, SPU customer service can provide definitive answers on specific recycling challenges.

Your Curbside Recycling Decision Checklist

When in doubt, use this checklist to help determine if an item belongs in your blue bin:

  • Is this item explicitly listed as accepted by Seattle Public Utilities for curbside recycling?
  • Is the item clean, empty, and dry, free of significant food or liquid residue?
  • Is it a rigid plastic container (bottles, tubs, jugs), metal can, glass bottle/jar, or clean paper/cardboard?
  • Is the item larger than 2 inches by 2 inches to avoid falling through sorting equipment?
  • Does it contain any hazardous materials, electronics, plastic film/bags, or Styrofoam?
  • If unsure, have you checked the ‘What do I do with…?’ tool on the SPU website?

Common Recycling Mistakes in Seattle

Avoid these common pitfalls to keep Seattle’s recycling stream clean and effective:

  • Wishcycling: Placing non-recyclable items (e.g., ceramics, garden hoses, textiles) into the blue bin, hoping they will be recycled, leading to contamination.
  • Bagging recyclables: Putting loose recyclables inside plastic bags or trash bags; bags jam sorting machinery and recyclables inside are often discarded.
  • Not rinsing containers: Leaving significant food residue in containers contaminates paper and other materials, rendering them unrecyclable.
  • Recycling small items: Shredded paper (unless bagged according to specific SPU rules for paper), bottle caps, or small plastic items (under 2x2 inches) often fall through sorting equipment and become trash.
  • Including plastic film/bags: All plastic bags, wraps, and films are NOT accepted curbside in Seattle due to equipment entanglement; they require special drop-off.
  • Assuming all plastics are recyclable: Only rigid plastics #1, #2, and #5 are generally accepted curbside in Seattle; items like plastic cutlery, toys, or clamshell containers are often not accepted.

Frequently Asked Questions (FAQ)

Q: Can I recycle pizza boxes in Seattle?

A: Only the clean, non-greasy parts of a pizza box can be recycled. If the box is soiled with grease or food, tear off the clean lid and recycle that portion, placing the greasy bottom in your compost (if available) or the trash.

Q: Do I need to remove labels from jars and bottles?

A: No, it’s not necessary to remove labels from glass bottles or plastic containers. The recycling process can handle these, so a quick rinse is sufficient.

Q: What about plastic cutlery or straws?

A: Plastic cutlery, straws, and other small, non-rigid plastics are generally not accepted in Seattle’s curbside recycling. They are too small or not the correct type of plastic for the sorting machinery and should be placed in the trash.
