Seattle Curbside Recycling: Your Guide to Proper Sorting

Seattle residents play a crucial role in maintaining our city’s commitment to sustainability through proper curbside recycling. Understanding what can and cannot go into your blue bin is essential for effective waste diversion and to prevent contamination of valuable materials. This guide provides clear, practical instructions based on Seattle Public Utilities (SPU) guidelines, helping you navigate the system with confidence. By following these straightforward steps, you contribute directly to a cleaner, greener Seattle.

Navigating Seattle’s Curbside Recycling System

Seattle operates a comprehensive curbside recycling program for residential properties. This system is designed to recover valuable resources and reduce landfill waste. Your primary resource for up-to-date and official information is Seattle Public Utilities (SPU). Their website provides detailed lists, tools, and updates on acceptable materials and program changes. Familiarizing yourself with these resources is the first step towards successful recycling.

Accepted Materials: What Belongs in Your Blue Bin

Your blue recycling bin is designated for specific categories of materials. Generally, these include:

  • Paper & Cardboard: This encompasses newspapers, magazines, catalogs, junk mail, office paper, phone books, paperboard (like cereal boxes – flatten them!), and corrugated cardboard (must be flattened and cut to fit entirely within the bin).
  • Plastic Containers: Only plastic bottles, jugs, and tubs (e.g., yogurt containers, butter tubs) are accepted. Look for a neck and a wider base. Rinse them clean.
  • Glass Bottles & Jars: All colors of glass bottles and jars are accepted. They must be empty and rinsed. Lids should be removed and can be recycled separately if they are metal, or put in the trash if plastic.
  • Metal Cans: Aluminum and steel (tin) cans, including beverage cans, food cans, and aluminum foil (balled up), are recyclable. Ensure they are clean and dry.

Unaccepted Materials: Common Contaminants to Avoid

Many items commonly mistaken for recyclables can cause significant problems for the recycling process. These “wish-cyclers” contaminate good materials, damage machinery, and increase processing costs. Never place these items in your blue bin:

  • Plastic Bags & Film: This includes grocery bags, dry cleaning bags, plastic wrap, and any stretchy plastic film. They jam sorting equipment.
  • Styrofoam: All forms of Styrofoam (packaging peanuts, cups, take-out containers) are not accepted.
  • Food-Soiled Items: Pizza boxes with grease stains, paper plates, or containers with significant food residue must go in the compost or trash.
  • Ceramics & Dishes: Pottery, ceramic mugs, and glassware (other than bottles/jars) melt at different temperatures and are not recyclable curbside.
  • Diapers, Clothing, and Textiles: These are not recyclable in the blue bin. Consider donation for textiles or proper disposal for diapers.
  • Hazardous Waste: Batteries, electronics, paint, chemicals, and motor oil require special disposal.

Preparing Your Recyclables for Collection

Proper preparation is key to ensuring your items are actually recycled.

  1. Clean & Dry: Rinse all plastic, glass, and metal containers thoroughly. Food residue attracts pests and contaminates paper products.
  2. Empty: Ensure containers are completely empty.
  3. Flatten Cardboard: Break down and flatten all cardboard boxes. This saves space in your bin and on the collection truck.
  4. Remove Lids: For plastic containers, remove the lids. Small plastic lids are generally too small to be sorted and should go into the trash. Metal lids can often be recycled if they are large enough or placed inside a metal can.
  5. No Bags: Do not bag your recyclables. Place them loose in the blue bin.

Decision Checklist for Your Recycling Bin:

  • Is this item explicitly listed as accepted by Seattle Public Utilities (SPU) for curbside recycling?
  • Is the item completely clean and dry, free from any food residue or liquid? (Rinse containers thoroughly).
  • Is this item made of plastic film, Styrofoam, or ceramics? (If yes, do not recycle curbside).
  • Is the item smaller than 2x2 inches? (If yes, dispose of in trash as small items fall through sorting machinery).
  • Are all cardboard boxes flattened and cut to fit entirely within the recycling bin without overflowing?
  • Does this item contain any batteries or hazardous materials? (If yes, seek special disposal, not curbside).

Curbside Collection Logistics & Bin Guidelines

Seattle’s recycling collection generally occurs on a designated day, often bi-weekly, depending on your address.

  • Collection Day: Check your specific collection schedule on the SPU website or through their mobile app.
  • Bin Placement: Place your blue bin at the curb or alley by 7:00 AM on your collection day. Ensure it’s accessible and not blocked by vehicles or other obstructions.
  • Lid Closed: The lid must be completely closed to prevent litter and protect contents from rain.
  • Weight Limits: While specific weight limits can vary, avoid overloading your bin to the point where it cannot be safely lifted by collectors or the automated arm.
  • No Overflow: Items should fit completely inside the bin with the lid closed. Overflowing bins may not be collected. If you consistently have too much recycling, you might need an additional bin (contact SPU).

Beyond the Blue Bin: Resources for Other Waste

Many items not accepted in your curbside bin can still be recycled or disposed of responsibly through other programs.

  • Electronics (E-Waste): Computers, TVs, and other electronics can be recycled at designated King County E-Cycle Washington drop-off sites.
  • Batteries: Household batteries (alkaline, rechargeable) should never go in the trash. Drop them off at various retail locations or transfer stations.
  • Hazardous Waste: Paint, chemicals, and motor oil require proper disposal at King County Household Hazardous Waste facilities.
  • Plastic Film: While not accepted curbside, many grocery stores offer drop-off bins for clean, dry plastic bags and film.
  • Compost: Food scraps and yard waste are collected separately in Seattle’s residential composting program.

How to Verify in Seattle Today

Uncertain about a specific item? Here’s how to get current, accurate information for Seattle residents:

Simply type in the item you’re questioning (e.g., “plastic packaging,” “coffee cup lid”) for an immediate, definitive answer on how to dispose of it.
  2. Download the Seattle Recycles App: For on-the-go verification, download the official Seattle Recycles mobile app. It provides the same “Look Up An Item” functionality and personalized collection calendars right on your smartphone.
  3. Consult the SPU Recycling Brochure: If you prefer a physical guide, Seattle Public Utilities often mails out updated recycling brochures. You can also typically find printable versions on their website, providing a quick visual reference for common items.

Common Recycling Mistakes to Avoid

Avoiding these common errors helps ensure the efficiency and effectiveness of Seattle’s recycling program:

  • Placing plastic bags, plastic film, or Styrofoam in the recycling bin, which jams machinery and contaminates bales.
  • Recycling items with significant food residue or liquid, which contaminates paper and other materials, making them unrecyclable.
  • Including small items (e.g., loose plastic bottle caps, shredded paper not contained in a paper bag) which fall through sorting equipment.
  • Assuming all plastic items are recyclable; only specific shapes (bottles, jugs, tubs) are accepted, not plastic packaging or toys.
  • Not flattening cardboard boxes, leading to bin overflow, missed collection, or damage to collection equipment.
  • Putting electronic waste, batteries, or hazardous waste in the curbside bin, posing fire hazards and damaging processing equipment.

Frequently Asked Questions (FAQ)

Q: Can I recycle shredded paper in my blue bin?
A: Yes, but it must be contained. Place shredded paper inside a paper bag (like a brown paper lunch bag), fold or roll the top closed, and put it in your blue bin. Loose shredded paper is too small and falls through the sorting machinery.

Q: Do I need to remove labels from jars and bottles?
A: No, you do not need to remove labels from glass jars or plastic bottles. The recycling process accounts for these. Just ensure the containers are clean and empty.

Q: What if I have more recycling than fits in my blue bin?
A: Seattle Public Utilities offers options for additional capacity. You can request a larger recycling cart or a second cart for a fee. Alternatively, you can take excess recyclables to a King County Transfer Station or Community Recycling & Disposal event.
