Seattle's Curbside Recycling: Essential Guidelines for Plastic and Paper

Living in Seattle means being part of a community committed to environmental stewardship, and proper curbside recycling is a cornerstone of this effort. Understanding the specific rules for plastic and paper items not only helps reduce waste but also ensures the efficiency of our local recycling programs. Contamination from incorrect items can send entire batches of otherwise recyclable materials to the landfill, undermining our collective efforts. This guide aims to clarify Seattle’s curbside recycling guidelines for common plastic and paper household items, helping you recycle right.

Seattle’s Curbside Recycling Principles: Clean, Dry, and Empty

Seattle Public Utilities (SPU) maintains clear, fundamental principles for all curbside recycling: Clean, Dry, and Empty. Adhering to these three words is crucial for preventing contamination, which is the primary enemy of effective recycling. Any food residue, liquid, or non-recyclable material can spoil a whole bin of otherwise good recyclables, leading to increased processing costs and ultimately, more waste sent to landfills. Always ensure items are free of food, liquids, and any non-recyclable attachments before placing them in your blue bin.

Mastering Plastic Recycling: Bottles, Jugs, and Tubs Only

When it comes to plastics in Seattle, the rule is simple: focus on bottles, jugs, and tubs (BJT). These are rigid plastic containers commonly used for beverages, detergents, and food products like yogurt or butter. Understanding what to include and, more importantly, what to exclude, is key to successful plastic recycling.

Accepted Plastic Items:

  • Plastic Bottles: Soda bottles, water bottles, milk jugs, detergent bottles, shampoo bottles.
  • Plastic Jugs: Bleach jugs, laundry detergent jugs, gallon milk jugs.
  • Plastic Tubs: Yogurt containers, butter tubs, sour cream containers, deli containers (empty and rinsed).

Preparation for Plastic:

  • Rinse thoroughly: Ensure all food residue is removed. A quick rinse is often sufficient.
  • Remove caps: Small caps (under 3 inches) should be removed and placed in the garbage. Larger caps (3 inches or more) can be reattached to the empty container.
  • No plastic bags: Never bag your recyclables. Place items loose in the bin.

Plastics NOT Accepted (and why):

  • Plastic Bags & Film: Grocery bags, produce bags, dry cleaning bags, bubble wrap, plastic film. These items wrap around sorting machinery, causing breakdowns and contaminating other recyclables. Return these to designated store drop-offs.
  • Styrofoam: Packaging peanuts, foam cups, take-out containers. Styrofoam is not recyclable through Seattle’s curbside program due to its brittle nature and inability to be processed effectively.
  • Clamshell Containers: Produce or bakery clamshells. These are often made from a different type of plastic that is difficult to process with bottles, jugs, and tubs.
  • Small Plastic Items: Items smaller than 2 inches, such as small bottle caps, cutlery, or broken plastic pieces, are too small for sorting equipment and fall through, ending up as waste.
  • Plastic Strapping/Banding: These also jam machinery.

Paper and Cardboard Recycling: Rules for Every Fiber

Paper and cardboard are widely recyclable in Seattle, but proper preparation ensures they don’t become contaminants. The goal is always to keep paper products clean, dry, and compact.

Accepted Paper and Cardboard Items:

  • Newspapers & Magazines: All types of newsprint and glossy magazines.
  • Junk Mail & Envelopes: Including window envelopes. Remove any plastic cards.
  • Mixed Paper: Office paper, school paper, brochures, pamphlets, phone books.
  • Paperboard: Cereal boxes, tissue boxes, paper towel/toilet paper rolls (flattened).
  • Corrugated Cardboard: Shipping boxes, moving boxes. Must be flattened.
  • Paper Bags: Brown paper grocery bags.

Preparation for Paper & Cardboard:

  • Keep Dry: Wet paper or cardboard can lose its fiber integrity and become unrecyclable.
  • Flatten: Flatten all cardboard boxes to save space in your bin and on the collection truck.
  • No Food Residue: Paper or cardboard contaminated with food, grease, or liquids (e.g., greasy pizza boxes, soiled paper plates) cannot be recycled. The clean portions of pizza boxes can be torn off and recycled, but the greasy parts should go to compost or garbage.
  • Shredded Paper: Shredded paper is NOT accepted in curbside bins. It’s too small for sorting equipment and creates litter. Small amounts can be composted, or larger quantities should be placed in the garbage.

Avoiding Recycling Rejection: Top Contaminants & Their Impact

Understanding common mistakes is just as important as knowing what to recycle. Contamination significantly impacts the recycling stream, making the process less efficient and more costly. Incorrect items can damage machinery, reduce the quality of recycled materials, and divert usable resources to landfills.

Here are the most common mistakes Seattle residents make that lead to recycling rejection:

  • Recycling plastic bags, plastic film, or styrofoam in curbside bins, which jams sorting machinery and contaminates other recyclables.
  • Leaving food residue (e.g., cheese, grease) in plastic containers or on paper/cardboard, contaminating entire batches and making them unrecyclable.
  • Attempting to recycle small plastic items (under 2 inches) like bottle caps or loose pieces, as they fall through sorting equipment and become trash.
  • Placing shredded paper loose in the recycling bin, leading to scattering and difficulty in processing at the recycling facility.
  • Assuming all paper is recyclable, overlooking wax-coated paper (e.g., milk cartons, coffee cups) or heavily greased paper (e.g., greasy pizza boxes).
  • Failing to flatten cardboard boxes, which takes up excessive space and makes collection less efficient.

Decision Checklist for Seattle Recyclers

Before placing an item in your curbside recycling bin, quickly run through this checklist to ensure you’re recycling correctly and avoiding contamination:

  • Is this item a clean, dry plastic bottle, jug, or tub (not a plastic bag or film)?
  • Is this item clean, dry paper or cardboard, free of food waste and coatings?
  • Have I rinsed all food residue from containers, and are they dry before placing in the bin?
  • Is this item smaller than 2 inches in any dimension? (Small items often cannot be sorted and should be garbagaged)
  • Is this item shredded paper, either loose or in a plastic bag? (If yes, it’s not accepted curbside)
  • Does this item contain any hazardous materials or electronics? (If yes, do NOT put in recycling)

Resources and What to Do When You’re Unsure

Seattle Public Utilities (SPU) is your primary resource for all things recycling. Their ‘Where Does It Go?’ online tool is invaluable for checking specific items. When in doubt, it’s always best to err on the side of caution: if you’re not 100% sure an item is recyclable in your curbside bin, dispose of it in the garbage. This prevents contamination and ensures that other genuinely recyclable materials aren’t rejected.

Frequently Asked Questions (FAQ)

Q: Can I put plastic grocery bags in my curbside bin?
A: No, plastic bags are a major contaminant that jam sorting machinery. Please return them to designated store drop-offs or reuse them.

Q: Do I need to remove labels from plastic bottles?
A: No, you generally do not need to remove labels from plastic bottles or jugs. The recycling process can typically handle them.

Q: What about pizza boxes?
