Introduction

Composting is a cornerstone of sustainable waste management, transforming organic waste into valuable resources like nutrient-rich fertilizers. In Portland, residents and businesses play a pivotal role in this process through the use of green bins. Understanding what can and cannot be disposed of in these bins is essential not only for effective composting but also for broader initiatives like manure recycling, which contribute significantly to environmental sustainability.

Residential Composting in Portland

For Portland homeowners, curbside compost collection is a convenient way to manage organic waste. The green bins accept a variety of materials that feed into the composting system:

Food Waste: All types of food scraps are welcome, including meat, poultry, fish, shellfish, eggs, cheese, dairy products, bread, baked goods, pasta, rice, beans, nuts, seeds, vegetables, and fruits.
Yard Waste: Leaves, weeds, grass clippings, vines, flowers, house plants, and plant clippings can be composted alongside food waste.
Paper Products: Paper coffee filters, paper tea bags, and pizza boxes (with any plastic or wax removed) are acceptable.

It’s important to avoid placing non-compostable items in the green bin to maintain the efficiency of the composting process and support initiatives like manure recycling.

Business Composting in Portland

Businesses in Portland have specific composting guidelines that differ slightly from residential practices:

Accepted Materials: Only food waste is permitted in business green bins. This includes raw or cooked food, plate scrapings, leftovers, and spoiled food.
Bin Liners: Businesses must use BPI-certified compostable bags exclusively.
Exclusions: Yard waste and food-soiled paper are not allowed, ensuring that commercial composting remains streamlined and effective.

By adhering to these guidelines, businesses contribute to reducing overall waste and support programs like manure recycling, which relies on effective organic waste management.

Yard Waste Guidelines

For homes and small apartment complexes (up to four units), yard waste can be composted along with food waste:

Allowed Yard Waste: Weeds, leaves, vines, grass, flowers, house plants, plant clippings, and pumpkins.
Branch Size: Small branches less than 4 inches thick and 36 inches long are acceptable.
Other Items: Food-soiled napkins and paper towels, as well as pizza delivery boxes without plastic or wax.

Proper disposal of yard waste not only enriches compost but also plays a role in manure recycling by providing additional organic material for recycling processes.

What’s Not Allowed

Whether you’re a homeowner or a business, certain items are prohibited in Portland’s green bins to ensure the composting process remains efficient and safe:

Non-Compostable Items: No coffee cups, paper plates, take-out food containers or wrappers, drink cups, straws, or utensils.
Misleading Labels: Items labeled as “compostable,” “biodegradable,” or “made from plants” are not allowed unless they are BPI-certified compostable bags.
Other Restrictions: Waxed paper, parchment paper, facial tissues, beverage stir sticks, toothpicks, plastic bags, plastic wrap, metal, glass, liquids, grease, or cooking oil must be excluded.

Improper items can contaminate the compost and hinder initiatives like manure recycling, which depend on pure organic inputs.

How Composting Benefits the Environment

Composting transforms organic waste into valuable products, reducing landfill usage and lowering greenhouse gas emissions. Additionally, it supports manure recycling by providing a steady supply of compostable material that can be converted into organic fertilizers, clean water, and renewable energy. This cycle not only minimizes waste but also promotes sustainable agricultural practices.
