Can Styrofoam Be Recycled?

Introduction

Every year, Americans throw away billions of foam cups and containers. This white, lightweight material takes up space in landfills and can last for centuries. Many people wonder: can styrofoam be recycled through waste management systems? The answer isn’t simple. While technically recyclable, most styrofoam ends up in landfills due to collection and processing challenges. This guide explores styrofoam recycling options, explains why it’s difficult, and offers practical solutions for eco-conscious consumers looking to reduce their environmental impact.

What Is Styrofoam? Understanding The Material

The Difference Between Styrofoam And EPS

Many people call all foam products “styrofoam,” but this isn’t accurate. True Styrofoam is a trademark owned by Dow Chemical Company for blue insulation boards used in construction.

What most people call styrofoam is actually expanded polystyrene foam (EPS). This white, lightweight material is made from polystyrene beads expanded with steam. It’s the stuff used for:

Coffee cups
Food containers
Packaging materials
Coolers
Protective packaging for electronics

For this article, we’ll use “styrofoam” (lowercase) as most people do when referring to EPS products.

How Styrofoam Is Made

The production process for styrofoam involves:

Creating tiny polystyrene beads filled with pentane gas
Heating these beads with steam
Expanding the beads to 40-80 times their original size
Molding the expanded beads into desired shapes
Cooling and setting the foam

This process creates a material that’s 95-98% air, making it extremely lightweight yet effective for insulation and protection.

Can Styrofoam Be Recycled Through Waste Management?

The Technical Truth About Styrofoam Recycling

Yes, styrofoam can be recycled—technically speaking. The material has recycling code #6 (polystyrene). When properly collected and processed, it can be turned into:

Picture frames
Crown molding
Office supplies
Insulation
Other plastic products

But there’s a big gap between what’s possible and what happens in practice.

Why Most Waste Management Programs Don’t Accept Styrofoam

Despite being technically recyclable, most curbside programs reject styrofoam for several reasons:

High volume-to-weight ratio: Styrofoam takes up massive space while weighing very little, making transportation costly.
Food contamination: Food residue makes recycling difficult and expensive.
Special equipment needed: Standard recycling machinery can’t process foam efficiently.
Limited market demand: There’s little economic incentive for recyclers to process styrofoam.
Transportation costs: Moving bulky styrofoam to specialized facilities is expensive.

This chart shows the acceptance rate of various materials in typical municipal recycling programs:

Material	Acceptance Rate in Curbside Programs
Aluminum	95%
Paper	90%
Plastic #1 & #2	80%
Glass	75%
Plastic #5	35%
Styrofoam (EPS)	<10%

Where Does Styrofoam End Up?

When not recycled, styrofoam follows these paths:

Landfills: Most foam ends up here, taking up to 500+ years to break down.
Incineration: Some waste management facilities burn styrofoam, releasing potentially harmful chemicals.
Environmental pollution: Lightweight foam easily blows away, ending up in waterways and natural areas.
Ocean waste: Breaks down into microplastics that harm marine life.

The Environmental Impact of Styrofoam Waste

Landfill Problems

Styrofoam creates significant problems in landfills:

Takes up 30% of landfill space by volume
Persists for centuries without breaking down
Leaches chemicals as it slowly degrades
Contains styrene, a possible human carcinogen

Wildlife and Ecosystem Threats

When styrofoam enters the environment:

Animals mistake small pieces for food
Marine creatures ingest microplastics
Birds use foam pieces in nest building
Chemical components enter the food chain

Carbon Footprint Concerns

The styrofoam lifecycle generates environmental costs:

Production requires petroleum, a non-renewable resource
Manufacturing releases greenhouse gases
Transportation of bulky products increases carbon emissions
Limited recycling means more virgin material production

Specialized Styrofoam Recycling Options

Drop-Off Locations for Styrofoam
