Residential Curbside Recycling Rules in Portland, Oregon

Portland, Oregon, is known for its commitment to sustainability, and effective curbside recycling plays a crucial role in these efforts. Understanding the specific rules for residential properties ensures your efforts contribute positively to the city’s waste reduction goals and avoids contamination fees. This guide provides clear, actionable steps for Portland residents to recycle correctly.

Understanding Your Portland Recycling System

Residential properties in Portland typically utilize a multi-bin system for curbside collection, managed by contracted waste haulers. This generally includes a large mixed recycling roll cart (often blue or green) for paper, plastics, and metals, and a separate, smaller bin specifically for glass bottles and jars (often a yellow crate). Many homes also have a green compost bin for food scraps and yard debris, though this guide focuses on recycling specifics. Collections for recycling are typically bi-weekly, while compost and trash are usually weekly. Your specific collection schedule and bin types are determined by your service provider.

Your Mixed Recycling Roll Cart: Accepted Materials

Your mixed recycling cart is designed for a range of common household items, provided they are clean and dry.

Paper and Cardboard

  • Accepted: Clean paper (junk mail, newspapers, magazines, phone books, catalogs), paperboard (cereal boxes, tissue boxes), corrugated cardboard (shipping boxes).
  • Preparation: Flatten all cardboard boxes. Break down large pieces to fit inside the cart. All paper and cardboard must be dry.

Plastics

  • Accepted: Plastic bottles, jugs, and tubs numbered #1, #2, #4, #5. This includes items like milk jugs, detergent bottles, yogurt cups, butter tubs, and shampoo bottles.
  • Preparation: Rinse containers thoroughly. You may leave plastic caps and lids securely attached to plastic bottles/jugs. Do not include plastic clamshell containers or plastic bags.

Metals

  • Accepted: Aluminum cans (soda, beer), tin and steel food cans (soup, vegetable, pet food).
  • Preparation: Rinse thoroughly. Labels can remain on cans.

Glass Bottle and Jar Recycling: Specifics

Portland’s system uses a dedicated bin for glass to prevent breakage and contamination of other recyclables.

  • Accepted: Food and beverage glass bottles and jars of any color (e.g., soda bottles, jam jars, pickle jars).
  • Preparation: Empty and rinse thoroughly. Remove all lids and caps (metal lids can go in mixed recycling if clean, plastic caps go in the trash). No need to remove labels.
  • Not Accepted: Drinking glasses, ceramics, window glass, mirrors, Pyrex, or any other type of glass that is not a food or beverage bottle/jar. These items melt at different temperatures and contaminate the recycling stream.

Common Contaminants: What to Keep Out

Placing non-recyclable items into your bins leads to “wishcycling,” which contaminates valuable materials and increases processing costs. Here’s what not to put in your curbside recycling:

  • Plastic Bags & Film: Grocery bags, produce bags, plastic wraps, and films jam sorting machinery. Take these to designated store drop-offs.
  • Styrofoam: Packing peanuts, foam cups, or takeout containers are not accepted in curbside recycling.
  • Food Waste: Any significant food residue contaminates paper and plastics, making them unrecyclable. Use your compost bin for food scraps.
  • Electronics (E-Waste): Computers, TVs, phones, and other electronics contain hazardous materials and require special disposal.
  • Textiles: Clothing, fabric scraps, or old linens should be donated or taken to textile recycling facilities, not curbside.
  • Small Items: Anything smaller than 2 inches (e.g., shredded paper not contained in a paper bag, single bottle caps not attached to bottles, small plastic pieces) can fall through sorting machinery and become litter or contamination.

Proper Preparation for Successful Recycling

Correct preparation is key to ensuring your recyclables are actually recycled.

  1. Rinse Thoroughly: All food and beverage containers (plastic, glass, metal) must be empty and rinsed clean. Even a small amount of residue can contaminate a whole batch.
  2. Dry Materials: Paper and cardboard must be dry. Wet paper can clog machinery and reduce fiber quality.
  3. Flatten Cardboard: Break down and flatten all corrugated cardboard boxes. This saves space in your bin and helps with collection efficiency.
  4. Manage Lids and Caps:
    • Plastic caps and lids should be securely reattached to plastic bottles and jugs #1, #2, #4, #5.
    • Remove all lids and caps from glass bottles and jars.
    • Clean metal lids from glass jars can go into the mixed recycling bin.
  5. No Shredded Paper (Loose): Shredded paper is too small for sorting equipment. Place it in a paper bag before putting it in your mixed recycling cart, or compost it.

Key Decisions for Portland Recycling

Use this quick checklist to decide what goes where:

  • Is this item clean and completely dry, free of food residue?
  • Does this item precisely match an accepted material type for this specific recycling bin?
  • Is this item a plastic bag, film, or wrap? (If yes, do NOT put in curbside bin).
  • Is this item Styrofoam packaging or a Styrofoam food container? (If yes, do NOT put in curbside bin).
  • If it’s paper or cardboard, is it free of significant food grease, wax coatings, or plastic lining?
  • Is the item larger than 2 inches in any dimension? (Smaller items can fall through sorting machinery).

Avoiding Common Recycling Mistakes in Portland

Being aware of these frequent errors can significantly improve the quality of Portland’s recycling stream:

  • ‘Wishcycling’: Placing items not explicitly listed as accepted into the recycling bin, hoping they can be recycled, leading to contamination.
  • Failing to clean containers: Leaving significant food residue (e.g., yogurt, peanut butter) in jars and tubs, which contaminates other materials in the bin.
  • Recycling plastic bags/film: Placing grocery bags, produce bags, or plastic film in curbside bins, which causes severe machinery jams and forces manual removal.
  • Including Styrofoam: Attempting to recycle Styrofoam packaging or food containers, which are not accepted in Portland’s curbside program and must go to specialized drop-offs or landfill.
  • Not flattening cardboard: Placing unflattened boxes into the mixed recycling bin, taking up excessive space and preventing other items from being collected efficiently.
  • Recycling small items: Tossing items smaller than 2 inches (e.g., unbagged shredded paper, single bottle caps) into the mixed stream, as they fall through sorting machinery and are lost.

Frequently Asked Questions About Portland Curbside Recycling

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

A: No, you do not need to remove labels from cans or glass and plastic bottles/jars. The recycling process can handle these.

Q: Can I recycle plastic clamshell containers (like those used for berries or takeout)?

A: No, plastic clamshell containers are generally not accepted in Portland’s curbside mixed recycling bins. They are often made from a different type of plastic (PET #1 thermoform) that is not easily processed with bottles and tubs. Place these in your garbage.

Q: What should I do with shredded paper?

A: Shredded paper is too small to be sorted effectively when loose. Collect shredded paper in a paper bag (like a lunch bag or grocery bag) and then place the sealed paper bag into your mixed recycling cart. Alternatively, shredded paper can be added to your compost bin if it’s free of plastic or shiny coatings.
