Is Styrofoam Recyclable? Important Recycling Tips
Styrofoam, or expanded polystyrene (EPS), is a big problem in recycling. It’s everywhere, from food containers to packaging. But, only a few recycling facilities accept. Most of it goes to landfills, where it takes 500 years to break down.
Learning about styrofoam recycling is key. It helps us make better choices about what we use and throw away. In this article, we’ll look into styrofoam’s recycling challenges. You’ll get tips to help you deal with styrofoam recycling.
Key Takeaways
- Styrofoam, also known as expanded polystyrene (EPS), is notoriously difficult to recycle due to its lightweight and bulky nature.
- Only a small number of recycling facilities accept styrofoam, and less than 1% of the 15 million metric tons produced annually is actually recycled.
- Styrofoam is non-biodegradable and can take up to 500 years to decompose, contributing to significant environmental pollution when sent to landfills or littered.
- Recycling centres face challenges in processing styrofoam due to the difficulty in reverting it to its basic form and the presence of harmful toxins.
- Exploring eco-friendly alternatives to styrofoam, such as biodegradable packaging and reusable containers, can help reduce our environmental impact.
Understanding Styrofoam and EPS: What’s the Difference?
When we talk about packaging and insulation, “Styrofoam” and “EPS” are often mixed up. But they are not the same. Let’s look at what makes Styrofoam and EPS different.
True Styrofoam vs. Expanded Polystyrene
Styrofoam is a brand name for a special type of EPS by DuPont for insulation. EPS is used in many things like egg cartons and packaging peanuts. Even though both are polystyrene foam, they are not the same.
Common Uses in Everyday Life
EPS foam is light and easy to use, making it great for insulation and packaging. Styrofoam is strong and good for building things.
Properties and Composition
EPS foam keeps buildings cool and saves energy. Styrofoam also keeps buildings warm and saves energy. But EPS is lighter and less strong than Styrofoam.
Property | Styrofoam | EPS |
---|---|---|
Density | Higher | Lower |
Compressive Strength | Greater | Slightly Lower |
Thermal Insulation | Excellent | Excellent |
Recyclability | Challenging | Possible, but Challenging |
In short, Styrofoam and EPS are similar but different. They are used in different ways in our daily lives.
Environmental Impact of Styrofoam Waste
Styrofoam, also known as expanded polystyrene (EPS) foam, is harmful to the environment. It breaks into small pieces, polluting land and water. This can confuse wildlife, causing serious harm. Styrofoam also harms the ozone layer and contributes to climate change.
The Earth Resource Foundation says Styrofoam makers were the fifth biggest polluters in 1986. Over 90,000 workers face dangers from styrene each year. Styrene, found in Styrofoam, can make food and drinks unsafe.
The damage from Styrofoam waste is huge. Washington University reports Styrofoam takes 500 years to decompose. A Recycling Revolution says Styrofoam fills 30% of landfills. The U.S., the biggest trash maker, is especially hit by this problem.
Switching to eco-friendly options like paper or reusable dishes can help. By using less Styrofoam, we can protect our planet. This reduces plastic pollution’s harm.

Is Styrofoam is Recyclable: The Truth About Recycling Symbols
Expanded polystyrene (EPS), known as Styrofoam, has a recycling symbol. But, it’s not usually accepted in curbside recycling. This is because EPS is light and bulky, making it hard to collect and transport.
Why Most Curbside Programs Don’t Accept It
EPS needs special equipment to be recycled, which many facilities don’t have. Its lightness also makes it expensive to store and move. These reasons stop local authorities from adding it to curbside recycling.
The Challenge of Processing EPS
EPS is hard to clean because it’s porous. Often, it’s dirty with food or drink spills. This dirtiness can ruin the quality of the recycled material, making it useless.
Special Recycling Facilities and Requirements
But, some places have special EPS recycling facilities. For example, the Foodservice Packaging Institute lists places where you can drop off foam for recycling. Some shipping stores also take packaging peanuts for reuse.
Despite these efforts, recycling EPS is still a big challenge. Only about 12% of EPS is recycled, according to the industry. New methods, like thermal compaction and using limonene solvents, are being tried to make recycling better.
Recycling Symbols | What They Mean |
---|---|
Recycling code 70 GL | Mixed glass containers |
Recycling code 71 GL | Clear glass containers |
Recycling code 72 GL | Green glass containers |
Even though recycling EPS is tough, we can help by choosing biodegradable packaging. We can also use less Styrofoam and find new uses for EPS products.
How Styrofoam Recycling Actually Works
Recycling styrofoam, or expanded polystyrene (EPS), is a complex task. Yet, there are specific steps to recycle this common material. The EPS recycling process includes cleaning, foam shredding, and pelletising.
First, styrofoam is cleaned to remove dirt and residue. This is key to making sure it’s ready for recycling. Then, the clean styrofoam is shredded into small pieces. This makes it easier to move and process.
The last step is pelletising. Here, the shredded foam is melted and turned into a uniform paste. This paste is then formed into small pellets. These pellets can be used to make new items, like picture frames and park benches.
Chemical recycling is a new method that can handle dirtier foam. It breaks down the polystyrene at a molecular level. But, recycling EPS is still expensive. It’s often cheaper to make new EPS from oil.
Recycling Step | Description |
---|---|
Cleaning | Removing contaminants and residue from collected styrofoam |
Foam Shredding | Reducing the bulky styrofoam into smaller, more manageable pieces |
Pelletising | Heating and melting the shredded foam into dense, uniform pellets |
Chemical Recycling | Breaking down polystyrene at the molecular level for more efficient recycling |
The EPS recycling process may seem complex. But it shows our dedication to recycling this common packaging material.
Eco-Friendly Alternatives to Styrofoam
Styrofoam, or expanded polystyrene (EPS), harms the environment. Businesses and consumers are looking for better options. Luckily, many eco-friendly alternatives are now available. They work well and reduce waste and harm to the planet.
Biodegradable Packaging Options
Companies are making new materials from natural things like mushrooms, corn starch, and seaweed. These biodegradable solutions, like molded pulp and seaweed packaging, break down and improve soil. They also keep things cool and safe, just like styrofoam.
Reusable Container Solutions
Using foam packaging again can cut down on waste. People and businesses are choosing reusable containers. These are made from strong, eco-friendly materials like organic fabrics and bamboo. They help reduce single-use waste and support a circular economy.
Innovative Sustainable Materials
New materials are being created for sustainable packaging. They match styrofoam’s performance but are better for the planet. Examples include air pillows, biodegradable paper foams, and mushroom packaging. These options help businesses meet customer needs and protect our planet.
