Portland, Oregon Curbside Recycling Rules: Your Essential Guide

Thu Mar 05 2026

Navigating curbside recycling and composting in Portland, Oregon, can sometimes feel like a puzzle. Our local rules are specific, designed to minimize contamination and ensure that what you put in your bins truly gets recycled or composted. Understanding these guidelines is key to keeping our community green and our recycling system efficient.

Why Portland’s Specific Recycling Rules Matter

Portland’s recycling system is tailored to local processing capabilities and market demands for recycled materials. Unlike some other areas, our system often has unique requirements for sorting and material acceptance. Following these guidelines closely is crucial. Incorrect items, even small ones, can contaminate an entire truckload of recyclables, diverting otherwise good materials to the landfill. This ‘contamination’ increases processing costs, damages machinery, and undermines the effectiveness of our collective recycling efforts. Your diligence directly supports sustainable resource recovery in the Portland metropolitan area.

Your Green Cart: Mixed Recycling (Paper, Cardboard, Plastics, Metal)

Your large green recycling cart is for a specific range of mixed recyclables. Items must be empty, relatively clean, and placed loosely in the cart.

Paper Products: This includes newspapers, magazines, junk mail, office paper, phone books, paperboard (like cereal boxes, tissue boxes – flatten these), and milk/juice cartons (rinse and flatten). Please do not include shredded paper loose; place it in a paper bag. Heavy-duty cardboard should be flattened and cut to fit inside the cart without overflowing.
Plastic Containers: Only #1 and #2 plastic bottles and jugs with necks (like soda bottles, milk jugs, detergent bottles) are accepted. Additionally, rigid plastic tubs (like yogurt, sour cream, butter containers) are generally accepted. All plastics should be empty, rinsed, and lids removed (lids usually go in the trash). No other plastic types, such as clam shells, plastic cups, or plastic bags, are accepted.
Metal Items: Steel, tin, and aluminum cans (soda, food cans) are accepted. Rinse them clean. Aluminum foil and trays are generally not accepted in curbside recycling; verify with Metro’s tool for current guidelines.

Your Blue Bin: Glass-Only Recycling

Portland has a dedicated blue bin specifically for glass. This separation is vital because broken glass can contaminate other recyclables, making them harder or impossible to process. It also poses a safety hazard for workers.

Accepted: Only glass bottles and jars, any color. They must be empty and rinsed. Labels can remain. Remove all lids; metal lids can often be recycled with other metals if larger than 2 inches, but plastic lids typically go in the trash. No drinking glasses, ceramics, window glass, mirrors, Pyrex, or broken glass are accepted here.

Your Green Cart: Food Scraps & Yard Debris Composting

Portland’s green cart also serves as your curbside compost bin, accepting both food scraps and yard debris. This diverts significant organic waste from landfills.

Food Scraps: ALL food scraps are accepted, including meat, poultry, fish, bones, dairy products, fruits, vegetables, bread, pasta, and coffee grounds (with filters). Food-soiled paper products like paper towels, napkins, and pizza boxes (no plastic liners) are also compostable. Food scraps can be placed loose in the bin, or in BPI-certified compostable bags. Regular plastic bags are never allowed.
Yard Debris: Leaves, grass clippings, small branches (less than 4 inches in diameter and 36 inches long), and garden trimmings are accepted. No dirt, sod, rocks, or large stumps.

The ‘No’ List: Materials NOT Accepted in Any Curbside Bins

Many common household items are not suitable for curbside recycling or composting due to contamination risks, processing difficulties, or safety concerns. Placing these items in your bins is a major source of contamination.

Plastic Bags & Film: Never put plastic bags, plastic film, or flexible packaging in your green mixed recycling cart. They tangle machinery at processing facilities. Instead, consider taking clean, dry plastic bags to designated store drop-offs.
Styrofoam: All forms of Styrofoam (packing peanuts, cups, takeout containers) are not accepted.
Electronics (E-waste): Computers, TVs, phones, and other electronics contain hazardous materials and must be recycled through specialized programs.
Batteries: All batteries (AA, AAA, D, button, rechargeable) must be kept out of curbside bins. They can pose fire hazards.
Hazardous Waste: Paint, chemicals, motor oil, and pesticides require special disposal.
Clothing & Textiles: Donate usable clothing or find textile recycling programs.
Diapers, Medical Waste, Pet Waste: These are always trash.
Garden Hoses, Christmas Lights, Cords: These ‘tanglers’ cause serious problems for sorting equipment.
Ceramics, Drinking Glasses, Window Glass: These are different types of glass than bottles/jars and melt at different temperatures, contaminating glass recycling.

Decision Checklist for Portland Recyclers

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

Is this item explicitly listed as accepted for this specific bin on the official Portland Metro ‘What to do with’ recycling guide?
Is the item clean and dry, free of significant food residue, liquids, or grease that could contaminate other recyclables?
If it’s a plastic container, is it a #1 or #2 plastic BOTTLE or JUG with a neck, or a rigid tub (e.g., yogurt, sour cream)?
If it’s glass, is it a bottle or jar, and is it placed only in the blue glass-only bin, rinsed and without a lid?
If it’s a food scrap, is it unwrapped or securely contained within a BPI-certified compostable bag inside the green cart?
Will this item fit loosely in the correct bin without forcing, overflowing, or being contained within a non-recyclable bag?

Common Recycling Mistakes in Portland

Avoid these frequent errors to ensure your recycling efforts are effective:

Wishcycling: Placing items into recycling bins hoping they are recyclable (e.g., ceramics, plastic toys, small metal parts), often leading to contamination of the entire load.
Not rinsing containers: Leaving significant food residue (e.g., peanut butter, yogurt, sauces) in jars, bottles, and cans, which attracts pests and contaminates other clean recyclables.
Bagging recyclables: Placing loose mixed recyclables inside plastic bags; these bags are not sorted at facilities and cause equipment jams, resulting in the entire bag being sent to landfill.
Incorrectly disposing of plastic film/bags: Plastic bags, plastic film, and flexible packaging are NOT accepted in curbside recycling bins and are major contaminants that wrap around machinery.
Mixing glass: Placing glass bottles and jars in the mixed recycling green cart instead of the separate blue glass-only bin, leading to broken glass contaminating other materials and posing safety risks.
Composting non-BPI certified items: Using ‘biodegradable’ or non-certified compostable bags, plastics, or food service ware in the food scraps bin; only BPI-certified products fully break down in commercial compost facilities.

Beyond the Curb: Proper Disposal for Special Items

Many items not accepted in curbside bins have responsible disposal options in Portland:

Batteries: Drop off at many retail stores (e.g., Home Depot, Best Buy), Metro’s Household Hazardous Waste facilities, or local battery recyclers.
Paint & Chemicals: Metro’s Household Hazardous Waste Facilities accept a wide range of hazardous materials by appointment or during designated drop-off hours.
Electronics (E-waste): Recycle through Oregon E-Cycles at various collection sites, including many electronics retailers and specific recycling centers. Search the Oregon E-Cycles website for locations.
Motor Oil: Many auto parts stores accept used motor oil for recycling.
Large Rigid Plastics: Some harder-to-recycle plastics, like plastic laundry baskets or large buckets, may be accepted at specific recycling depots or transfer stations. Always confirm with the facility before dropping off.
