The 'Compostable Bags Recyclable' Myth
The idea that you can recycle compostable items is a widespread misunderstanding. You might be surprised to learn that studies show nearly one-third of people incorrectly place compostable packaging into their recycling bins. This simple mistake creates big problems for recycling programs. Let's explore why the "compostable bags recyclable" concept is a myth.
Why They Contaminate the Recycling Stream
Recycling facilities are designed to sort and process specific materials like glass, metal, paper, and certain plastics. Compostable bags are not on that list. When you toss a compostable bag into your recycling bin, the sorting machines cannot distinguish it from other plastics. This single bag can ruin a large batch of recyclable packaging. The presence of compostable materials makes the entire recycling process more difficult and expensive.
Key Takeaway: Compostable items are considered contaminants in the recycling system. They lower the quality of the final recycled materials.
Designed to Decompose, Not Be Remade
Compostable and recyclable materials have opposite goals. A compostable bag is made from materials like PLA (polylactic acid), which comes from plant sources. These compostable materials are designed to break down completely. In an industrial composting facility, high heat and moisture trigger a process called hydrolysis. Microbes then consume the material, turning it into natural elements like water and carbon dioxide.
Recyclable plastics, like PET, are made to be durable. They can be melted down and reformed into new products. The table below shows the key differences.
Feature |
Compostable (PLA) |
Recyclable (PET) |
|---|---|---|
End-of-Life |
Breaks down into natural elements |
Remade into new products |
Source |
Plant-based (renewable) |
Petroleum-based |
Heat Tolerance |
Low; softens around 60°C |
Higher; more durable |
This shows why the "compostable bags recyclable" belief is incorrect. A compostable bag is designed to disappear, while a recyclable one is designed to be reused. Their chemistries are simply incompatible.
Your Step-by-Step Disposal Guide
You now know that compostable bags do not belong in recycling. So, what should you do with them? Following the right steps ensures your eco-friendly choice has a positive impact. These sustainable end-of-life strategies will help you dispose of your bags correctly.
Option 1: Industrial Composting for Compostable Packaging
The best destination for a compostable bag is an industrial composting facility. These large-scale operations create the perfect environment for decomposition.
Industrial composting systems use specific conditions to break down materials quickly.
High Temperatures: The compost pile must reach and maintain temperatures between 120°F and 160°F. This heat is generated by microbial activity.
Controlled Moisture: Adequate moisture is essential for microbes to survive and work. The facility manages water levels to speed up the process and prevent overheating.
Under these controlled conditions, a compostable bag can break down in about 3 months. This process turns your waste into valuable, nutrient-rich soil. You can find a local facility by using online tools. The BPI's 'Find A Composter' project and the Compost Manufacturing Alliance (CMA) facility locator are great resources to start your search.
Option 2: Home Composting (With Certified Bags)
You can compost some bags at home, but you must check the label first. Only bags specifically marked as "Home Compostable" will break down in your backyard bin. Home composting systems operate at lower temperatures and have more variable moisture levels.
The table below shows the main differences.
Feature |
Home Compostable |
Industrially Compostable |
|---|---|---|
Temperature |
Lower, variable temperatures |
High, consistent heat (131-140°F) |
Breakdown Time |
Longer (6-12 months) |
Faster (around 3 months) |
Certification |
TÜV Austria OK Compost HOME |
BPI Certified, ASTM D6400 |
Tip: For successful home composting, tear the bag into smaller pieces. This helps it break down faster. Always maintain a good balance of "greens" (food scraps) and "browns" (dry leaves) and turn your pile regularly to add air.
Option 3: The Last Resort - The Trash Can
If you cannot find a composting facility and the bag is not certified for home use, your last option is the trash can. This is the least preferred of all end-of-life scenarios. When a compostable bag ends up in a landfill, it gets buried under tons of other waste. This environment lacks oxygen.
Without oxygen, the bag and its organic contents undergo anaerobic decomposition. This process releases methane, a greenhouse gas that is much more potent than carbon dioxide. Sending a compostable item to the landfill unfortunately negates many of its environmental benefits.

Quick Guide: Compostable vs. Recyclable
Understanding the labels on your products is key to proper disposal. This quick guide will help you tell the difference between compostable, recyclable, and biodegradable items so you can make the best choice for your sustainability goals.
Compostable: Breaks Down into Natural Elements
Compostable materials are designed to return to the earth. When placed in the right conditions, these items break down completely into natural elements.
A truly compostable product decomposes into water, carbon dioxide, and nutrient-rich biomass. This process leaves no toxic residue behind and creates healthy soil.
You can identify these products by looking for official certification marks.
BPI Certified: Meets standards for industrial composting systems in North America.
OK Compost HOME: Certified to break down in a backyard compost pile.
These labels guarantee the compostable materials will decompose safely, turning waste into a valuable resource for the planet.
Recyclable: Remade into New Products
Recyclable items are meant to have a second life. Instead of breaking down, they are collected and reprocessed into new goods. The process of designing for recyclability ensures materials can be used again. Your local recycling programs collect items like plastic bottles and containers. These are then sorted, cleaned, shredded, and melted into pellets. Companies use these pellets to create everything from new bottles to clothing and construction materials. You can spot these items by looking for the classic Mobius Loop (♻️) symbol.
Biodegradable: An Often-Misleading Term
The term "biodegradable" can be confusing. While it sounds eco-friendly, it often lacks important details. Biodegradable materials will break down over time, but the term itself does not specify how long it will take or what conditions are needed. According to the FTC Green Guides, a product can only be marketed as biodegradable if it completely decomposes within one year of disposal. Many biodegradable materials do not meet this standard, especially in a landfill. For this reason, you should always prefer items clearly labeled as compostable.
Remember, the "compostable bags recyclable" concept is a myth. Your compostable bags are designed for composting, not recycling. Following these sustainable end-of-life strategies helps reduce harmful landfill emissions and supports your commitment to sustainability.
Your correct disposal options are:
Send your compostable bag to an industrial composting facility.
Use a certified home compost bin if the bag is approved for it.
Place it in the trash as a final resort.
Adopting these eco-friendly practices makes a real difference. Now you can solve this green puzzle every time. Choose certified eco-friendly products, know your local options, and go for a greener pack. ♻️
