Seattle Curbside Recycling Rules: Your Guide to Accepted Items

Seattle is committed to sustainability, and your role in proper curbside recycling is crucial. Understanding the specific rules for what can and cannot go into your residential recycling bin not only helps the environment but also ensures the efficiency of the city’s recycling programs. This guide provides clear, actionable information to help every Seattle resident become a curbside recycling expert, minimizing contamination and maximizing material recovery.

Seattle’s Curbside Recyclables: What’s Accepted?

Knowing exactly what items are accepted in Seattle’s residential curbside bins is the first step towards effective recycling. The city focuses on common household materials, ensuring they can be efficiently processed.

Paper and Cardboard

Recycling paper and cardboard helps save trees and energy. In Seattle, you can recycle:

  • Corrugated Cardboard: Shipping boxes, flattened.
  • Paperboard: Cereal boxes, tissue boxes, paper towel rolls, flattened.
  • Mixed Paper: Newspapers, magazines, junk mail, envelopes (windows are generally acceptable), phone books, catalogs, paperback books, paper egg cartons.
  • Milk and Juice Cartons: Gable-top cartons (like milk or juice cartons) and aseptic cartons (like soup or broth cartons).
  • Paper Bags: Clean paper bags.

Ensure all paper and cardboard are clean and dry. Flattening boxes saves space in your bin and helps with collection.

Plastic Containers

Seattle accepts rigid plastic containers, primarily those shaped like bottles, tubs, and jugs. Look for the recycling symbol, but more importantly, focus on the container’s form:

  • Bottles: Drink bottles (soda, water), detergent bottles, shampoo bottles.
  • Tubs: Yogurt, sour cream, butter, and similar food tubs.
  • Jugs: Milk jugs, juice jugs, water jugs.
  • Plastic Nursery Pots: From plants, typically #2 or #5 plastic.

All plastic containers must be empty, clean, and dry. No plastic bags, film, or Styrofoam is allowed.

Metal Cans and Foil

Metal items are highly valuable for recycling due to their infinite recyclability.

  • Aluminum Cans: Soda and beer cans.
  • Steel/Tin Cans: Food cans (vegetables, soup, pet food).
  • Aluminum Foil: Clean aluminum foil and disposable aluminum trays (pie plates, roasting pans), crumpled into a ball larger than a golf ball.

Rinse cans thoroughly to remove food residue.

Glass Bottles and Jars

Glass is another infinitely recyclable material.

  • Bottles: Beverage bottles (soda, beer, wine).
  • Jars: Food jars (jam, pickles, sauces).

All glass must be empty, clean, and dry. Remove metal lids and place them with other metal recycling. Plastic lids from glass jars should be discarded in the garbage.

Non-Recyclables: Items to Keep Out of Your Bin

Placing non-recyclable items into your curbside bin, often called “wishcycling,” can contaminate entire loads, making them unusable and increasing waste processing costs. Understanding what to exclude is as important as knowing what to include.

The Big No-Nos: Plastic Bags, Styrofoam, Electronics

These are among the most common contaminants:

  • Plastic Bags and Film: Grocery bags, bread bags, produce bags, dry cleaning bags, and plastic film (like plastic wrap, bubble wrap). These items jam sorting machinery and are never accepted in curbside bins. Many grocery stores offer drop-off programs for plastic film.
  • Styrofoam: Packing peanuts, foam cups, takeout containers, and protective packaging. Styrofoam is not accepted in curbside recycling in Seattle. Search for specialized drop-off locations or dispose of it in the garbage.
  • Electronics (E-Waste): Computers, TVs, cell phones, batteries, and other electronic devices contain hazardous materials and should never go in your recycling bin or garbage. Seattle has dedicated e-waste recycling facilities.

Food Waste and Contaminated Items

While food waste is compostable, it does not belong in the recycling bin. Items heavily soiled with food (e.g., greasy pizza boxes) cannot be recycled with other clean paper products. Even small amounts of food residue can spoil an entire batch of recyclables.

  • Food Scraps: Use your food and yard waste bin for these.
  • Soiled Cardboard/Paper: If a pizza box bottom is heavily greased, tear off the clean top and recycle that, discarding the soiled portion.

Hazardous Waste and Batteries

These items pose significant safety and environmental risks:

  • Batteries: All types of batteries (alkaline, rechargeable, car batteries) should be recycled at designated drop-off locations. Never put them in curbside bins, as they can cause fires.
  • Hazardous Waste: Paint, motor oil, pesticides, cleaning chemicals, and fluorescent bulbs must be taken to household hazardous waste facilities.

Preparation is Key: The ‘Empty, Clean, Dry’ Rule in Practice

Proper preparation of recyclables is paramount to prevent contamination and ensure materials can be successfully processed. The golden rule in Seattle is “Empty, Clean, and Dry.”

Rinsing and Drying

Any container that held food or liquid must be rinsed out. A quick rinse with water is usually sufficient. This prevents food residue from molding or attracting pests, which can contaminate other clean recyclables and create unpleasant odors at sorting facilities. After rinsing, allow items to air dry or give them a quick shake to remove excess water.

Flattening Cardboard

Flattening cardboard boxes (like shipping boxes or cereal boxes) is essential for two reasons:

  1. Space Efficiency: Flattened boxes take up significantly less room in your recycling bin, allowing you to fit more.
  2. Collection Efficiency: Flattened items are easier for collection trucks to compact and for sorting machinery to process.

Managing Lids

  • Plastic Lids from Plastic Containers: For plastic bottles and tubs, generally, leave plastic caps and lids on if they are securely attached and smaller than 3 inches in diameter. Larger plastic lids can be placed loosely in the bin.
  • Lids from Glass Jars: Remove metal lids from glass jars and place them loosely in your metal recycling. Plastic lids from glass jars should be discarded in the garbage.
  • Pump/Spray Nozzles: These are typically made of mixed materials and should be removed and discarded.

Decision Checklist for Your Recycling Bin

Use this quick checklist before placing an item in your curbside bin:

  • Is the item explicitly listed on Seattle Public Utilities’ accepted materials list?
  • Is the item completely empty, clean, and dry, free from any food or liquid residue?
  • Is it a rigid plastic container (bottles, tubs, jugs) and NOT a plastic bag, film, or Styrofoam?
  • Is the item larger than a credit card? Small items often fall through sorting machinery.
  • If it’s paper or cardboard, is it clean and dry, without significant grease or food stains?

Navigating Confusing Items and Avoiding ‘Wishcycling’

Some items consistently cause confusion. Understanding these nuanced rules can significantly improve your recycling habits and help Seattle reach its waste diversion goals. The practice of “wishcycling”—putting an item in the recycling bin hoping it’s recyclable—often does more harm than good.

Greasy Pizza Boxes

A common dilemma! The top of a pizza box, if clean, can often be recycled. However, the bottom, typically soaked in grease and food residue, is not recyclable through curbside programs. Tear off and recycle the clean top portion, and compost or discard the greasy bottom.

Small Plastics

Items smaller than a credit card, even if made of accepted plastic types (like pill bottles or small plastic toys), are generally not accepted in curbside recycling. They are too small for sorting machinery and often fall through the cracks, ending up as non-recyclable residue. Dispose of these in the garbage.

Shredded Paper

While paper is recyclable, shredded paper is often problematic. Its small size causes it to fall through sorting screens and contaminate other materials. Seattle Public Utilities advises placing shredded paper in a paper bag and then putting that bag into your food and yard waste bin for composting, not your recycling bin. Alternatively, some local community centers or businesses offer secure paper shredding and recycling events.

The “When in Doubt, Throw It Out” Principle

If you’re unsure whether an item is recyclable, it’s always best to err on the side of caution. Placing a non-recyclable item in the bin can contaminate an entire load, leading to more waste in landfills. Use Seattle Public Utilities’ official resources (mentioned below) to look up specific items. If you still can’t find clear guidance, it’s better to dispose of it in the garbage than to risk contaminating the recycling stream.

Seattle’s Recycling Resources and Enforcement

Seattle provides robust resources to help residents recycle correctly. Utilizing these tools and understanding compliance helps everyone contribute to a cleaner city.

Official Resources

The primary resource for all Seattle residents is Seattle Public Utilities (SPU). Their website features a comprehensive “What to do with my stuff” tool, allowing you to search for hundreds of specific items and get detailed disposal instructions for recycling, composting, or garbage. You can also find downloadable guides, collection calendars, and contact information for specific questions.

Understanding Compliance

SPU actively monitors curbside recycling to ensure compliance with guidelines. While the focus is on education, repeated contamination can lead to service adjustments or communication from SPU. The collective effort of residents adhering to these rules ensures the efficiency and cost-effectiveness of Seattle’s recycling program, preventing valuable resources from being landfilled due to avoidable contamination.

Common Curbside Recycling Mistakes in Seattle

Avoiding these frequent errors will significantly improve the quality of Seattle’s recycling stream:

  • Placing plastic bags, plastic film, or other flexible plastics into the curbside recycling bin, causing machinery jams.
  • Failing to rinse food containers (e.g., yogurt cups, peanut butter jars), leading to contamination of other recyclables.
  • Attempting to recycle Styrofoam (packing peanuts, foam cups, takeout containers) which is not accepted curbside.
  • Putting greasy pizza boxes or cardboard with significant food residue into the paper recycling stream.
  • Recycling electronics, batteries, or hazardous waste in curbside bins, posing safety and environmental risks.
  • Including small items (smaller than a credit card) that fall through sorting equipment.

Frequently Asked Questions

Q: Can I recycle plastic grocery bags in my curbside bin?

A: No, plastic bags and other plastic film (like bread bags or bubble wrap) jam sorting machinery and are not accepted in Seattle’s curbside recycling. You can often drop them off at participating grocery stores for specialized recycling.

Q: What should I do with a greasy pizza box?

A: If the bottom of the pizza box is heavily soiled with grease or food, it should be composted in your food and yard waste bin, or if composting isn’t an option, placed in the garbage. However, the clean top portion of the box can be torn off and recycled with other cardboard.

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

A: No, it’s not necessary to remove labels from glass bottles or jars, or from plastic containers. The recycling process accounts for these. Just ensure the containers are empty, clean, and dry.

Q: Are small plastic items, like pill bottles, recyclable?

A: Generally, no. Items smaller than a credit card, even if made of recyclable plastic, are too small for the sorting machinery at recycling facilities. They often fall through and end up as waste. Please place these small items in your garbage bin.

Q: Where can I recycle electronics or batteries in Seattle?

A: Electronics (e-waste) and batteries should never go into your curbside recycling or garbage bins. Seattle has designated drop-off locations and special events for these items. Check the Seattle Public Utilities “What to do with my stuff” tool for specific nearby facilities.
