Your Guide to Seattle Curbside Recycling Rules

Living in Seattle comes with a commitment to environmental stewardship, and understanding your curbside recycling rules is a big part of that. Proper recycling reduces landfill waste, conserves resources, and supports a cleaner city. This guide simplifies Seattle Public Utilities (SPU) guidelines, helping you recycle correctly and avoid common pitfalls.

Seattle’s Curbside Recycling Basics: What Goes In & What Stays Out

Seattle’s recycling program focuses on collecting specific materials to ensure efficient processing. Knowing what is accepted and, crucially, what is not, is the first step to becoming a recycling pro.

Accepted Items (Generally):

• Paper & Cardboard: This includes newspapers, magazines, junk mail, flattened cardboard boxes (cereal boxes, shipping boxes), paperboard, and paper bags. Keep them dry and free of food residue.
• Glass: Only glass bottles and jars are accepted. Rinse them clean and remove lids.
• Metal: Aluminum and tin cans (soda cans, food cans) are recyclable. Rinse them clean.
• Rigid Plastics: Look for plastic bottles, jugs, and tubs (like yogurt cups, butter tubs, milk jugs). These must be clean, dry, and empty. Refer to specific material guidelines below for more detail.

Items Never Accepted in Curbside Bins:

• Plastic Bags, Film, & Flexible Packaging: This is a major contaminant. Plastic bags tangle machinery and must be kept out. This includes produce bags, bread bags, shrink wrap, and plastic film packaging.
• Styrofoam: All forms of Styrofoam (packing peanuts, cups, food containers) go in the trash.
• Electronics (E-Waste): Computers, TVs, phones, and other electronics require special drop-off.
• Batteries: All types of batteries need proper disposal to prevent fires and pollution.
• Ceramics & Dishes: These items are not recyclable with glass bottles.
• Garden Hoses, Wires, Ropes: These “tanglers” damage sorting equipment.
• Diapers, Medical Waste: These belong in the trash for hygiene and safety.
• Clothing & Textiles: Donate or dispose of these properly; they don’t go into curbside recycling.

Preparing Your Recyclables: Clean, Dry, and Loose Requirements

Proper preparation is just as important as knowing what to recycle. Contaminated or improperly prepared items can cause an entire batch of recyclables to be sent to the landfill. Remember these key rules:

• Clean & Dry: All food and beverage containers must be rinsed clean and dry. Leftover food residue or liquids can contaminate paper and other materials, making them unrecyclable. A quick rinse is usually sufficient.
• Empty: Ensure containers are completely empty. Liquids can spoil paper and cardboard.
• Loose: Never put your recyclables in plastic bags. Items should be placed directly and loosely into your recycling cart. Plastic bags (even if filled with acceptable recyclables) are considered contaminants and will cause the entire bag’s contents to be landfilled.
• Flatten Cardboard: Flatten cardboard boxes to save space in your bin and on the collection truck.

Material-Specific Guidelines: From Pizza Boxes to Plastic Containers

Recycling rules can get nuanced for certain items. Here’s a closer look at specific materials:

• Pizza Boxes: Only the clean, non-greasy portions of pizza boxes are accepted. Tear off and compost or trash any sections soiled with grease or food.
• Plastic Containers: Focus on rigid plastic bottles, jugs, and tubs. If it’s a squeeze bottle, a milk jug, a yogurt cup, or a butter tub, it’s generally good. The chasing arrows symbol with numbers 1, 2, or 5 can be a helpful guide, but the container’s shape and rigidity are more important. No plastic clamshells, trays, or packaging from baked goods or produce.
• Glass: Only glass bottles and jars (for food and beverages). No drinking glasses, window glass, ceramics, or pyrex. Remove lids (metal lids can go in with metal cans if separated, plastic lids go in the trash).
• Metal Cans: Aluminum cans and steel/tin food cans are accepted. Rinse them clean.
• Shredded Paper: Collect shredded paper in a paper bag (not plastic!) and place the sealed paper bag in your recycling bin. Loose shredded paper is too small and falls through sorting equipment.

Beyond the Bin: What to Do with Non-Curbside Recyclables

Many items not accepted in your curbside bin still have responsible disposal options. Knowing these alternatives is crucial for comprehensive waste reduction.

• Plastic Bags & Film: Take clean, dry plastic bags, plastic film, and shrink wrap to designated drop-off locations at grocery stores or large retailers. Never put them in your curbside bin.
• Electronics (E-Waste): Visit E-Cycle Washington collection sites or King County Transfer Stations for proper electronics recycling. Many retailers also offer take-back programs.
• Batteries: Household batteries can be dropped off at various retail locations or King County Transfer Stations. Car batteries have separate recycling points.
• Hazardous Waste: Paints, chemicals, pesticides, and other hazardous materials should never go in your trash or recycling. Utilize King County’s Household Hazardous Waste facilities for safe disposal.
• Clothing & Textiles: Donate usable clothing to charities. For unwearable textiles, check with local textile recycling programs.

Avoiding Rejected Loads: Identifying Common Contaminants

Contamination is the biggest challenge for recycling programs. A few incorrect items can lead to an entire truckload of otherwise good recyclables being sent to the landfill. Use this checklist and be aware of common mistakes to ensure your recycling efforts count.

Your Seattle Recycling Decision Checklist

• Is this item clean, dry, and empty with no food or liquid residue left inside?
• Is it a rigid plastic container (bottle, tub, jug), glass bottle/jar, metal can, or clean paper/cardboard?
• Does this item contain plastic bags, plastic film, or other flexible plastics (which must go to store drop-offs or trash)?
• Is this item smaller than two inches in two dimensions (e.g., bottle caps, loose shredded paper, small plastic pieces), making it too small to be sorted?
• Is this item explicitly on the ‘never accepted’ list (e.g., Styrofoam, ceramics, electronics, batteries, garden hoses)?
• When in doubt, have I used the official Seattle Public Utilities ‘Where Does It Go?’ tool for a definitive answer?

Common Recycling Mistakes in Seattle

• Placing recyclables inside plastic bags or adding any plastic bags/film directly into the curbside bin.
• Not thoroughly rinsing food or beverage containers, leaving residue that contaminates other items and equipment.
• Including non-recyclable items like Styrofoam, ceramics, clothing, electronics, or garden hoses in the recycling bin.
• Recycling small items (e.g., bottle caps, shredded paper not in paper bags) loose, which fall through sorting machinery.
• Assuming all plastics with a chasing arrows symbol are accepted; only specific rigid container types are typically allowed.
• Putting greasy pizza boxes or other food-soiled paper/cardboard directly into recycling instead of composting or trashing.

Frequently Asked Questions

Q: Can I recycle plastic clamshell containers from berries or baked goods?

No, plastic clamshells are generally not accepted in Seattle’s curbside recycling. They are made of a different type of plastic that is difficult to process with bottles and tubs. These should go in the trash.

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

No, you do not need to remove labels from glass bottles and jars. The recycling process is designed to handle them.

Q: What if my recycling bin is rejected?

If your recycling bin is rejected, the collector usually leaves a tag explaining why. Common reasons include contamination (like plastic bags or food waste) or incorrect items. Review the tag, remove the problematic items, and present your bin again on the next collection day.

Q: Are greasy pizza boxes recyclable?

Only the clean, non-greasy portions of pizza boxes are recyclable. Tear off and discard any sections stained with food or grease, as these contaminate the paper fiber. The clean cardboard can then be recycled.
